Sunforce 45444 600W Wind Turbine

I purchased this windmill to augment a solar panel I use to charge a 12 volt battery bank. I have a solar powered well system for watering cattle, and the solar was not keeping up during times of low light. I intend for this unit to be an augment to my current system, not the only source of electrical current. I purchased this unit because it was 200 more watts output than the most popular sun force mill, but I was sort of disappointed that it is not made in USA like the 400 watt model. It is made in Taiwan. I guess this is ok, as Taiwan is an ally of the USA, so at least it was not made in PRC.

The package arrived quickly, and everything was in order and exactly as described. I assembled the unit in just under 30 minutes. There was an extra set of screws, nuts, and bolts included, and this could be handy for fumble fingers like myself. The fasteners are of good quality, and they were all present and accounted for. I did not have to use any of the extras (yet). Also included is a electro brake switch which I am not planning on using.

I first tried to mount the mill on a 21 foot piece of chain link fence top-rail, but it buckled over in the middle. I opted for a heavy piece of tubing from the chain link fence wholesaler, and it works great. I used #10 SOJ cable for my electrical connections. The mill started turning even before I had it hoisted all the way up, and it makes a pleasant enough sound as it turns. There is some small noticeable vibrations that may be due to a small imbalance in the rotor blades or something, but nothing that seems detrimental to the mill.

I made all the electrical connections without any trouble. The charge controller seems to be a fairly substantial unit, but could have been labeled on the back a little more clearly about which color wire goes to which screw, but the instruction manual cleared this up and there were no problems. The controller has a switch on the front that brakes the rotors to keep them from turning. I have not tested this in a stiff wind, but it stops the rotors in 8-10 MPH winds. Also included is a 30 amp panel meter to plumb into the electrical system in case you want to monitor current flow going to your battery bank.

The mill turns pretty much most of the time, although the charge light on the controller will only illuminate when there is a fairly good gust of sustained wind. This intermittent charging will work fine for me as this is supplemental to my solar panel, and I expect to get the most charging on cloudy days and windy seasons when the sun doesn't tend to shine so much. The unit is located in North East Oklahoma. I can readily see that another 21 ft of tower length would increase the output due to more undisturbed winds, but for now this is working pretty good, and I didn't have to use guy wires as the pole is attached to the side of the well house.

I am satisfied with this unit.

***** The Caveat ******

After reading so many negative reviews on this same product, I feel I must amend my review so that I am disclosing everything. Now pay attention: This unit requires wind to work! That's right, I know this is surprising, but this baby doesn't do a thing without wind! And even when it is working at max speed and full power, it will not replace your utility company, your neighbors will not be buying power off of your grid, and you will not be getting a fat rebate check from the grid. They won't be shutting down 3-mile island just because you have a wind turbine in the back yard. Hope this helps alleviate all the disappointed folks looking to start selling wind power and offering free rides to the moon.

The "Product Features" summary incorrectly states that it starts to "operate" at 4 mph, implying it's producing power. If you read the manual, there is a diagram that shows the turbine starts producing at 4 m/s that's 4 meters per second, or about 9 mph, and then the power production is small. It does not produce 600W until you get up to about 30mph. That's a **lot** of wind!

I bought this from Fry's electronics years ago. i installed this after a lot of effort. it really is hard to get something that high and stable at the same time. I suggest that you set up the pole first before you buy the turbine. Finally, after many tech support emails later, i could only get a trickle of a charge. After everything looked good, Sunforce said that i did not have enough wind! I found that was not true, because I tested it blowing as fast as possible, and I still get the same trickle charge. i'm just too tired of spending more time and effort on this turbine. It is now way past the return period, and it would be hard to prove that their product is defective in small claims since i'm not an engineer. I don't buy any sunforce products now. Neither should you. Also, i suggest that you try to turn the turbine with a drill first to see if you get a charge before installing. I should have done this first myself.

"OK, I'll take your bait and do the math.

The stated rotor diameter was 2 ft (2/3.28ft/m = 0.61 m or 0.3048 m radius) and the stated power was 600 watts. We'll assume air density to be 1.25 kg/m^3, and the coefficient of performance = 0.4. The Betz Limit of coefficient of performance is 59.3% and is the theoretical maximum Cp.

The basic equation is

P = rho/2 * area in m^2 * (velocity in m/s)^3 * Cp

The area is pi *r^2 = pi * 0.3048^2= 0.2919 m^2. (For reference, 1ft radius^2 * pi = 3.14 ft^2.)

Rearranging the equation, the velocity through the rotor must be

cube root of (P / (rho/2 * A * Cp))

Cube root (600/(0.625 * 0.2919 *0.40))

= Cube root (8222) = 20.18 m/s (1 m/s = 2.24 mph)

Regressing to the English mph, that's a windy 45.14 miles per hour.

Did I do that calculation right? Think I did. However, in such a small aperture, flow throttling likely would occur slowing the wind speed from that outside the turbine influence. The conclusion is that the 600 watts is a maximum rated power value. If the speed is cut in half, the power is one-eighth. So 22.5 mph yields 75 W, 11.25 mph yields 9 W, so this turbine is good for trickle charging a battery (just like a small solar module.)"

This wind turbine will make good yard art and a good plaything, but if you really want energy output you need a real wind turbine, and you need to put it up high in the sky where the speedier and non-turbulent wind is.

And as long as you are going to the significant expense of putting up a decent-sized tower, you might as well purchase a heavy-duty turbine that has enough output to pay for itself.

Oh yes, and none of this is worthwhile unless you have a good wind resource, and that can only be determined by measurement and/or careful and pro-level observation.

Wagan EL2201 Elite 400 Watt Pure Sine Wave Inverter

After much research, I bought the Wagan EL2201 because I was looking for a pure-sine-wave inverter in this size range and Wagan's other products seem to have a fantastic reputation.

There are lots of poor reviews on this one, and the problem seems to be the same: The unit starts up once, then immediately dies.

Problem: The cigarette lighter adapter comes with a fast-blow fuse. My unit did the same thing, and I found that the fuse (located inside the plug itself) had blown as soon as I plugged a very low-draw radio into the inverter. Inverters have lots of capacitors that need to charge then the unit powers up, creating a momentary large load that a slow-blow fuse can absorb, while a fast-blow cannot.

A 400-Watt inverter is pretty large to run on a cigarette lighter plug in the first place, and should definitely be run directly from the battery or hard-wired if you plan on using anything with a significant draw.

In fact, the instructions say NOT to use the cigarette lighter if you plan on running anything more than 150W.

Solution: Replace the fast-blow fuse included with the inverter with a slow-blow OR a larger fuse (do NOT exceed the rating of your vehicle's outlet!). This is a $0.50 fix and my inverter now works flawlessly!

I'm guessing that the poor reviews are from those who use the lighter adapter and have this problem, while the positives are those who either hard-wire or connect directly to battery.

Now my inverter works great, doesn't play havoc with ANYTHING (unlike my modified sine-wave inverters), and the price was right. The built-in USB is a nice touch too.

Bottom Line: Great inverter for the price if you don't mind replacing a fuse or hard-wiring. As mentioned before, an inverter this size probably should be hard-wired anyway.

I see some very negative reviews of this 400 watt inverter, but my wife and I have been very pleased. We live in a 100% solar home and have found the unit great for running our computer, printer, and powered computer speakers all at the same time. I have even run my Pioneer surround sound, DVD player, and 100watt powered sub-woofer at the same time. This use has been during the day, but there was certainly no shortage of power from the unit whenever the input voltage has been sufficient. One thing I need to mention is that I replaced the cord with the cigar lighter end on it with my own 2 foot long, 10 gauge wire with a three prong plug on it that plugs into our 12vdc in house recepticles. When I first bought the unit I had issues with low voltage signal too, but I do not believe the supplied cigar plug makes good enough contact to conduct the needed voltage. If you have the low voltage issue, try another type of plug or direct wire it. It is not unusual for this unit to be on 6 to 10 hours a day in our home and operates flawlessly. Yes, the cooling fan kicks on and off, but that is what it is supposed to do. I have also used it to charge various battery operated items drills, NiCad chargers, and the like, once again no problems. The ONLY reason I did not give it a five star rating is due to the issue with the cord. When you consider that most cigar lighter sockets are designed to handle 15 amps DC before blowing the on-board fuse (that's with the vehicle running), its easy to see why only the lightest of loads can be run using the supplied plug. Anything large use battery clips, direct wire or hardwire it into your system. Bought the unit about six months ago, should have done the review sooner.

If you draw more than about 5-10W the fan comes on and it's pretty noisy. Otherwise my unit works fine (I am not using the cigarette lighter plug).

Summary: If you're looking at this inverter, trust me and buy the Power Bright APS300-12 Pure Sine Power Inverter 300 Watt 12 Volt DC To 110 Volt AC instead! See why below --

Let me preface by saying that I had really high hopes for this inverter. What's not to love? Pure sine, 400 watts, USB port, yes please! My experience however, was far from pleasant. I was excited to test the (first) unit out after it arrived, as the inverter it was replacing, (180 watts) was not large enough to run the equipment I was trying to operate. I wanted to go with a pure sine unit as well because it would be powering electronics like audio gear or a TV. Well, I plugged it in only to find that the red light came on immediately. Bummer. I unplugged and plugged the unit back in and no change. I then decided to just give it a minute and tried the USB port to see if it would charge my phone. That at least worked. Shortly thereafter, the unit started smoking and emitting that ever-so-putrid burning electronics smell. DONE!

I let Amazon know and boxed it up to send back. Exchange was easy as pie and in a few days another (second) unit arrived. Excited to test the replacement out as I thought I may have just gotten a dud, I plugged it in and turned it on. No red light! Super! I then began to do some testing. I plugged in my laptop to the inverter and my touchpad immediately stopped working. Weird. So I did some more testing. I plugged in an audio amp and it worked but was very noisy on both the output and the sound the transformer was making on the amp itself. I plugged in a strand of LED Christmas lights and not all the lights would work. I plugged in my laptop again and noticed it would not charge. It would momentarily then stop then charge again and repeat. The transformer in the power supply was also making an abnormal buzzing sound. Through the course of more testing, I found that anything I plugged into the inverter that had a capacitive touch interface would stop working as soon as plugged it into the inverter (smartphone, touchpad, etc). I also found that the unit put out a large amounts of RF interference (AM radio distorted when inverter was on). Super weird. The fan was also running almost constantly even with a low load on the unit.

The RF issue has been commented on by others that have bought the Aims 180 pure sine inverter (which is as far as I can tell identical to the Wagan 180 watt pure sine version). So has the issue of blowing up, smoking, etc. Before I start to ramble, these units over promise and under deliver. I returned the second unit to Amazon after being so dissatisfied.

I ended up purchasing the Power Bright APS300-12 Pure Sine Power Inverter 300 Watt 12 Volt DC To 110 Volt AC. I could not be more satisfied with that unit. Way better built than the Wagan. Works as advertised. I was sold within minutes and will not hesitate to buy another Power Bright inverter.

I hope reading this saves you all the trouble I went through!

ReVIVE Solar ReStore XL 4000mAh Solar Charger Power Bank & USB Rechargeable External Battery Travel

So... a little preamble to my video I shot this in my car in the middle of the day, so it's kind of hard to see how bright the LED on the XL really is. The light is actually super bright. There are three LED bulbs in there so it gives off a lot of light when it's dark out, and my video doesn't really do it justice. Also, I apologize for the poor video quality. I initially shot it in 1080p, but the file was too big to upload so I had to downgrade it to a more memory-friendly setting. Anyways, I hope you like the video and find it at least somewhat helpful. This solar charger is awesome and I take it with me everywhere. I use my droid razr pretty hard, so I need all the juice I can get, and since I never seem to be near an outlet when I need one, this thing has been a lifesaver. Places I've taken it with me so far include: beach, camping, concert, and hiking. Also, one last thing. I reccomend using the OEM usb charge cable that your device came with because some generic USB cables are shoddy and they just don't seem to work as well on average.

I'm a bit dissapointed with this product. After leaving it in direct sunlight for over 20 hours, the charger capacity was still at 50%. When directly in the product details, it states 13 hrs for a FULL charge via solar. That being said, the main reason I bought this was to have a solar charger with enough Amps to charge my phones (EVO, GS3) AND tablet (Galaxy Tab 10.1), which it does. (FYI, The tab needs to be turned off to charge).

At 50% solar charged, it will only provide about 25% battery recharge to the tablet and approx 60% to my phone. So, granted it does work. But its unacceptable for a solar charger to not be able to charge 100% within 20 hrs of direct sun exposure.

I followed the instructions as stated by charging 100% via USB first and that provided 100% battery to my EVO and about 25% to the tablet. I'm torn on whether or not I keep this.

Want ReVIVE Solar ReStore XL 4000mAh Solar Charger Power Bank & USB Rechargeable External Battery Travel Discount?

I picked this up after spending an entire afternoon, from like 11:30 until a 7:30 game, at Lambeau Field for Family Day, tailgating. I had my son with me, we both had our iPhones and iPads. I didn't mind if his things got low on battery, but I wanted to make sure my phone stayed working so I had it available during the game. So every once in a while I'd plug it into the cigarette charger, and start the car and let it run for a bit, getting it back up to 80 or 85%. I realized I needed something to help me charge stuff up away from home.

So I did some digging and found this unit, and figured it was worth a shot. I liked that it wasn't strictly a solar charger, that you could charge it up via USB or wall outlet as well. On the down side you can't "charge and play", but for me that was less of a requirement.

I ordered this, and two extra solar panels. I fully charged the unit via the wall outlet, then turned an ipad onto one of my clock programs that keeps the screen lit without sleeping, and let it run down, then plugged it into this and let it run this down as well overnight while I had the LED light turned on. I then set it out on my patio table and let it charge itself back up. I had it sitting out all day, but I did not angle it to keep it tracking the sun directly (was busy doing other things). And about four oclock the sun's shadow is hitting the table anyway. It did not get fully charged during that stretch (was only about 6 or 7 hours in direct sunlight but not perpendicular to it at all times) but I didn't expect it to from what they said. The following day I did manage to get it topped off.

I bought two extra panels for it as well, and it definitely charges MUCH faster now, although I'm usually just using it via usb or wall outlet since I haven't been in a position to need to do it strictly via solar since purchase. But at least I know when I do, it'll be working well.

I, as another reviewer, had worried at first after peeling off the protective cover, since like his, mine was tucked under very well. I, too, wondered if I just did a boneheaded thing... But a tweezers got that last little corner out from under the plastic and it works like a champ.

If you get the add on panels, there is a button on the piece that bridges them to the XL (it came with one, and the panels came with one, so I actually have two adapters now in case one breaks or something) and when you push the button in sunlight, each panel has an LED that lights up to show it's completed the circuit and is charging the battery. Nice touch since otherwise there's no way to know for sure. Only complaint is the panels are kind of cheaply made, and one of mine came broken where the spring clip from the other inserts to hold it together. Fortunately I was able to use that on the outside, so there was nothing to hook there, and I can use it anyway.

The carabiner works for the unit alone, but there's no way I'd use it when I have the panels attached -as noted, they're poorly constructed where they hook to each other and those corners break easily. And I'm not sure I'd want to have this hanging from the suction cups either. They're double sided suction cups, like an hourglass, and not only would I not want this coming off the window at the wrong time while driving, they'd also impair the solar collection both cups on at the same time detracts from a large percentage of the solar panel area. But with my panels they'd not be very useful anyway.

12V / 18Ah Sealed Lead Acid Battery with Nut and Bolt Terminals - UVUB12180B1

I currently work on handicapped scooter equipment and have had extensive past experience with both computer and surveillance battery backup systems. I was well pleased with the batteries I received from eComElectronics through the Amazom site. The batteries were holding a good charge when received and performed well. In the past, I have purchased batteries from other sources that probably had an extensive time on the shelf before sold, as indicated by charge held upon receipt, as well as poor performance and response to recharging. Fortunately, I have the equipment to "exercise" batteries and get them up to par if they are able to. Most people, especially senior and/or handicapped needing replacement batteries for their equipment, are stuck with what they receive. To those people, from my experience, eComElectronics through Amazon is a reliable source. You not only get the support of the seller, but the backing of Amazon as well. As we all know, that is rare these days.

I bought this battery about 3 years ago and have had zero problems with this battery,I would buy another one of these if needed.

Multi-Use Vehicle Charger with Dual USB Ports and Dual 12 Volt Sockets - Magnadyne

This is a compact unit that I use to charge my cell phone and Garmin Nuvi 660 GPS using the two DC outlets, and to charge my Ipod Nano and Palm TX using the two USB outlets. I purchased a DC outlet extension cord at Radio Shack, and plug the charger into this so that I can position the charger right next to my seat.

I have tried various other chargers, and this is the most convenient one that I have found. In addition, the charger's capacity is sufficient to handle all of my gadgets being charged simultaneously.

Update July 22, 2009: Some months ago I replaced my Palm TX with an iPod Touch 2G. This unit charges it just fine using the same USB cable that I use to charge the Touch on my laptop.

Update August 23, 2009: I now charge my new BlackBerry Tour on this unit.

Update October 10, 2010: I just ordered my third unit--not because I had a problem with the other two, but because I wanted one for each car. Three years later my original unit is working just fine, as is the secind unit that I purchased a year after that. This is definitely a quality product that has performed well and held up well.

Update December 3, 2010: I just received my fourth unit that I am giving to one of my children to use in their car. This is a quality unit, and I have not had any problems with any of the units that I have bought.

Update August 1, 2012: Still using all four units without any problems. I have inserted a Powergen USB car charger into one of the 12V sockets, so now I have 4 USB ports--which I need for an iPad 3, two iPhones 4S, and a Kindle 3.

This device is really helpful not just for road warriors, but the average person who may have quite a number of devices that can be powered/charged by USB. It can handle and is fused at 20 amps.

I have two. On is 8 months old, the other about four months. You do not need to direct wire, but it is easy and in both my vehicles they are directly wired. One went to the front cigarette lighter wiring (about a 10 minute install) meaning I have a net of three cigarette lighter 12v outlets, plus two USB limited to 15 amps of the supporting OEM cigarette lighter fuse. In my second vehicle I have it direct wired to the battery main bus with an inline fuse (from an inexpensive $20 car amplifier power supply wiring kit). That was about 40 minute install. They can support a high powered laptop, treo, navigation unit, dvd player for the kids in back, and also charge an ipod or bluetooth set -all concurrently. It is also not difficult to open up the device and and use the 5v leg to run a direct 5v usb for hardwiring nav units.

The USB 5 volts is pretty clean and accurate checking with load on car start I am getting 5.1v and it settles at 4.95v, all well within tolerances for any usb device.

this is exactly what any blackberry, ipodding tuning road-warrior needs. dual 12v and 5v usb...genius.

my only hitch is that it takes a few seconds to buffer the power to the USB ports. My blackberry 7130e didnt start charging until a few seconds after the charger was plugged in. It works so im not concerned.

the usb ports have enough power to charge any USB device you can throw at it. I used this to supplement a high-speed portable hard drive that needed more power than my ultra portable laptop could supply it. so one plug went to PC usb for data and the other went to this baby and i was mint.

Love the mounting equipment. velcro or screw mount..your choice!

Cables and construction are solid and wire is heavy guage so it wont over heat under high load.

This unit would not charge my Nokia n900 using its USB outputs, until I modified it. But then, neither would at least three other dumb USB chargers I had on hand. Finally, I searched the net for n900 charging issues, and found that the n900 expects the charger to behave as the USB specification for dumb chargers reads, and many don't. Specifically, it expects to see 200 ohms resistance between the D+ and Dpins (the two center pins) and this unit appears to have an open circuit there. It seems that many phones, specifically some iPhone and Blackberry units, do not conform to the USB spec either, and expect to see around 2 volts on D+ which this unit provides.

So, if your phone will charge when connected to a computer, but not when connected to a dumb charger, this is why.

Using a magnifier to see the pins adequately, I connected D+ and Dtogether with a little solder bridge on the printed circuit board. Although this isn't a 200 ohm resistor, it's sufficient to inform the n900 that it's connected to a dumb charger, and it starts to charge.

The power is nicely filtered and regulated, no noise on the audio output while charging, so this plays fine in the car while charging while some other dumb chargers contributed so much buzzing from their switching regulators that it wasn't possible to listen to music.

I guess manufacturers of dumb chargers are between a rock and a hard place, as not every phone expects the same thing. The ultimate unit would offer a switch on each USB port to fix this. Those who don't want to open their charger can also make a USB cable with a short or 200 ohm resistor between D+ and Dto solve this problem.

This works and it comes with the hardware to mount it somewhere so it won't slide around. As an extension and socket splitter it is OK.

However they missed an essential trick on the USB power supply. If a device wants a smart USB powered device like an iPhone or iPod to see it as a high power source, and not as a data connection, it needs to short the data interface pins with a resistor not more than 200k ohms. That is in the USB spec. You can tell this hasn't been done because when you plug in an Android phone it asks if you want to mount as a media device or a hard drive.

So if you are looking for a neat way to power and charge a modern smart device then this isn't it. For the 2c it would cost them for the resistors the manufacturers really should have done this. I may even try it myself since it looks like there is room to work in there and I have an electronics lab to play in.

AGPtek® 30A Solar Panel Power Battery Charge Controller / Regulator 12V / 24V 30 Amp with PWM Type

Pros: High power handling, low price, PWM, descaler(?)

Cons: Manual is jibberish, technical data incomplete, display LED has only one segment, the function button feels really cheap

Comments: Before I get into my commentary, a tutorial and some useful information (stuff that should have been in the manual).

1 The charge controller will manage the load automatically.

2 The minimum battery voltage must be 12.35v or the load will cut off.

3 The setting for keeping the load on (without the timer function) is 6.6 (I will call this the normal setting from here on)

4 The load indicator is always yellow (provided you have sufficient battery power)

5 The charge controller won't work without a battery connected to it.

*/TUTORIAL:

The charge controller has a single digit LED mode indicator which has two states (flashing or steady) that indicate whether you are in programming mode (flashing) or display mode (steady). A number may or may not have a decimal point. If it has a (.) to the right of the number, it means that the number is a decimal. No decimal point means that the number you are looking at is a whole number (totally counter intuitive).

* Every time you press the button (if you are in the programming mode), the number will advance to the next higher number.

* A button press will only advance you to the next number.

* Holding the button down will not cause the number to automatically advance.

* Pressing the button will advance the number through all the whole numbers, all the decimal numbers and then cycle back to the beginning of the sequence (0-9 and then .0-.9)

In order to get to the normal setting, you must:

a) Press and hold the button (there is only one button on the far right) until the LED begins to flash.

b) Repeatedly press the button until you get to the number BEFORE the whole number you are trying to set (in my example, until you see the 5)

c) Press and hold the button once again. This will change the number to 6 and it will stop flashing.

** At this point, you have set the controller for 6.x and you will have to repeat the process to get to .6

d) Press and hold the button until the number begins to flash

e) Repeatedly press the button until you get to the decimal number before 6. (in my example, until you see 5.)

f) Press and hold the button once again. This will change the number to 6. and it will stop flashing.

If you have followed all the steps, have your battery connected (charged above 12.35v) and have your solar panel generating sufficient power, LED-1 (far left) will be green, LED-2 (center) will be green and LED-3 will be yellow (indicating that there is power at the load terminals.

End Of Tutorial */

Beyond the little tutorial above, there's not really much to know about the controller itself. It's pretty much a set and forget device. There is not reset button (to restore it to factory default) and no self test mode but for most purposes it shouldn't be necessary.

Another poster stated that the unit can desulfate batteries. I have not verified that but if that is true, then you should also be able to connect this charge controller to a battery charger to recondition batteries (and save on the expense of a standalone desulfator).

Thanks for reading.

This charger has been in service for over a week now. Batteries are charged every sunny day.

Keep in mind, this charger will take a max of 360 watts or 30 amps of solar power at 12 volts; 720 watts or 30 amps max at 24 volts. The "Product Description" doesn't say what size wire you can connect to this but I was able to use 8 gauge wire, no problem.

It does have an LED display for lighting options (on the load side) but I haven't tried to use it. Unless you're very good at reading/understanding broken-English, you'll probably have to read the little manual several times to successfully use the Lighting Control. Says it has a 30 amp load capacity.

Are there better 30amp PWM charge controllers available? Yes.. but not for $25!

This is an awesome little package. The instructions say that it can use any wire up to #4.

I used a size 8 .... as #8 and #10 are typical wires for solar and electrical. Even the solar for my house uses these size wires.

It does everything I need it to do, plus some. One thing I really needed to know, did it desulfate the batteries. YES IT DOES ... whoo hoo

Very user friendly and easy to use ... it has little pictures on the machine instead of words ... so you know exactly what goes where, and you don't have to worry about losing the instructions.

Samsung Intercept Moment 2 M910 Cell Phone Rapid Car Charger

Item works as advertised, but two things I noticed:

1-plastic housing that goes in cigarette lighter is somewhat flimsy and has already starting cracking on my unit. Don't rough house with this charger, treat it gently.

2-charging cuts on & off when USB connector is jostled forcefully. Not a big headache if you play nice but I thought you should know.

For the low price of the item you can/should overlook these two observations.

The charger stays put in cigarette lighter and on the phone USB connector. The coiled cord is flexible enough that you can handle the phone without either end pulling out of its intended location.

I got one in April by June it was no longer working. First day I plugged it in it had a burnt odor. It worked good for the short amount of time it did work. No warranty info came with it.

JR Products 48315 White Deluxe Assist Handle

I purchased JR Products 48315 Deluxe White Assist Handle from Amazon in the fall of 2010, but didn't install it on my travel trailer until the spring of 2011. It was easy to install drill 4 holes and attach with screws/flat washers (not included) and served its purpose well, but unfortunately it only lasted a few months. Although the mounting screws remain securely fastened to the trailer, the ends of the handle where it touches the side of the trailer (top and bottom) are cracking and the handle itself is pulling away from the trailer. If it lasted a few years I would have ordered another as a replacement. But apparantly the quality of the plastic isn't up to the task, so I'll have to shop for a better quality handle.

Cobra LI-7200-2 WX VP Micotalk GMRS/FRS 22-Channel 27-Mile Range 2-Way Radio with 10-Channel NOAA W

• Ultra-compact GMRS/FRS two-way radio with range of up to 27 miles
• 22 channels (7 GMRS/FRS, 7 FRS, 8 GMRS) with 142 privacy codes
• Full coverage of all government operated NOAA broadcasts
• Value pack includes two radios, rechargeable batteries, and two-port desktop charger
• One-year warranty

I had reasonable expectations for two-way radios like the consumer-grade Cobra Li7200 when I bought them. Based on my research, I knew that the whimsical claims on the bubble packs of 10's of miles of range (27 miles in the case of these radios) were pure fantasy. In urban areas, a mile or maybe two of range is the best you get; in more open areas, a little more. I also had a good idea of how the "privacy" codes work (they don't keep other people from hearing your broadcasts they allow you to tune out other people), the GMRS licensing requirements ($85/five years to the FCC to use the higher power GMRS frequencies, and the basic operation of two-way radios in general (they aren't cell phones you can't listen and talk at the same time, you have to pause after pressing the transmit key, the voice quality varies with transmitter power, distance, and intervening obstacles/terrain).

Based on my limited experience with these radios, I'm not disappointed. They worked fine on a recent vacation to a remote lake area. We used them to communicate between our rental house and the beach, while hiking on trails in the mountains [big kids and little kids move at different paces], between vehicles while caravanning to/from an off-road park, and to keep in touch while off-roading. While off-roading, one of the other vehicles had Motorola consumer-grade GMRS radios, and the Cobras and the Motorolas interoperated just fine, including both channel numbers (same channel number to frequency assignments) and CTCSS "privacy" codes. We probably never used them more than 1 to 2 miles apart, but we weren't going for any distance records.

The NOAA weather radio capability of the Cobra LI7200s was a key item for me. I wanted to be able to listen to NOAA weather service broadcasts because the area we were in was known for rapidly changing weather, and we needed to plan trips (hikes and beaching) without resorting to television news or non-existent Internet service. About the only weather radio features not found on these units is a weather radio "scan" (so I manually ploughed through the 10 weather frequencies until I found the local station, which wasn't hard because they broadcast continuously), and a "NOAA Weather Alert" (automatically monitors for NOAA WX ALERT signals) this last feature is appealing but wasn't available on the Cobras.

There seem to be two different approaches to batteries for consumer-grade GMRS radios; some take "AA" size batteries that can be rechargables or non-rechargables, others (such as the Cobra) use proprietary Lithium-Ion rechargables. If you know you can stick the radios in the charging cradle every day or two, the proprietary rechargables seem to be a good option they hold lots of power but are very lightweight. If you want the ability to go to non-rechargable backups when you are away from civilization, get a radio that takes them instead.

There appear to be three top-brand consumer-grade FRS/GMRS radios Motorola (actually made by a company called GIANT who license the Motorola name for this product), Midland, and Cobra. All three offer several models, mostly varying in size/output power (bigger size generally more power) and a few other features such as the NOAA weather radio capability. The Cobra LI7200s are the biggest/most powerful Cobras I found; I didn't find the size to be inconvenient nor the weight to be too much, and I wanted the maximum power I could get. If the Midland GXT900 had been shipping back in June 2008, I might very well have gotten those instead, as they have a higher rated power output registered with the FCC and they have the NOAA WX ALERT function, but I'm not unhappy with the Cobras. Some folks like the Motorola, others pan them. I wasn't sure I would like them because despite Motorola's excellent reputation with business radios the consumer-grade GMRS radios aren't really Motorolas.

For anyone thinking of using the Cobra with an external microphone/speaker, I will point out the the manual says "When using an external speaker/microphone accessory on channels 1-7 or 15-22, your microTALK radio will only operate on medium or low power." Since channels 8-14 are FRS channels that operate exclusively on low power, this means that these radios won't operate on high power with an external speaker/microphone accessory. This isn't a concern for me.

I didn't use the VOX (voice-activated transmit) or memory functions. I did use the channel scan functions to find clear channels (not a problem where we were located).

If you get a GMRS radio and you plan to use the GMRS frequencies, please go ahead and get properly licensed, then follow the radio rules about sharing channels. Have fun and save money on your cell phone bill!

I bought these specifically to use while skiing in Colorado. I was able to communicate with the other unit from everywhere across two peaks of the ski resort. When I went to a third peak (putting 1 peak between units) I couldn't commnicate with the other unit. 27 mile range it isn't. In the mountains over variable terrain and trees you're looking at more like a mile. However, it was perfectly acceptable performance or the ski resort application. I had no trouble communicating with someone at the base of the mountain when I was getting off of the highest ski lift. Easy to use & figure out. I'd recommend it.

I live in a very hilly area that doesn't lend itself to quality communication (even with cell phones). These radios are capable of 1 mile clear communication in a hilly terrain. I'm not sure of the range in open areas, but I'm sure it's much further.

They appear to be well made. One improvement would be to have a rubber ring surround the perimeter of the radio in case of a fall on a hard surface.

Radios charge and when almost fully charged, the leds get dim and eventually go out (when fully charged).

The li-on rechargeable battery easily comes out of its compartment without removing the belt clips.

Sound quality is excellent! I have a more expensive pair of Motorola radios with very poor quality audio.

Yuasa YUAM6212B YT12B-BS Battery

Replaced the Battery on my Triumph Bonneville 2009 EFI. This is the exact same as came stock. And it cranks nicely! I didn't even realize that my previous battery wasn't cranking so great until I replaced it.

From what I hear when they switched to EFI from carbs the battery got smaller to make room for the ECU. So every Bonnie, Scrambler, and Thruxton from 2009,2010 and possibly 2011 have this (smaller) battery YT12B-BS.

I hear that they increased the size on the 2012 and some of the 2011... to the standard 12-BS instead of the 12B-BS.

Almost every website (i'm looking at you amazon!)has this info wrong and assumes that '09,'10 have the same battery as previous years and the current year. Including the Yuasa US website!!!

Initially thought that I would not know what to do with adding the acid, but it was really easy. The battery came dry and all you have to do is follow instructions to add the acid. It was very safe to perform and after sealing it I waited a few minutes and installed the battery right away. I have a 2004 Yamaha FZ 6 and it started on my first try. Excellent product and I'm pleased with the purchase.

Go Power! GP-SW1500-12 1500-Watt Pure Sine Wave Inverter

I have bought two other brands that have failed. One never did work and I was still charged 20% to return it! I did some research and found the Go Power to be backed by a serious company. After over two years of continuous operation, 24/7/365, it has delivered quality power to my three computers, scanner, laser printer, DVR, satellite controllers, speakers, wave radio, well, you get the picture. Don't mess around with a cheaper product, you'll end up paying more in the long run. With what I know now, I would pay the $950 list price.

I'm a mobile DJ and bought this inverter to power my 4000 watt PA/Lighting system. It replaced a modified sine wave unit that was noisy (static) through the speakers. This unit is completely quiet and actually provides cleaner power then my mains service. It works very well and doesn't seem to break a sweat running the PA and lighting system also powering a laptop, mixer and effects rack. It is light weight and feels very sturdy. All of the connections are good and will accommodate 4ga battery cables. I also like the separate voltage and capacity displays to give me an idea of how much time remains.

This was a real plug and play unit for me since I waws bypassing a modified sine wave inverter. Very solidly built.

The only reason it didn't get 5 stars is there's nothing more than bar readouts for load and voltage and I prefer meters or digital readouts.

Three plus months in operation and I have yet to see any issues.

If needed, I would defintley buy another of these.

I would not buy this brand again, based on my bad experience. However, I bought mine back in 2003, so perhaps the bugs in this model have been worked out by now.

I would've given it 2 stars, but it did get me through Hurricane Sandy by powering my 2 refrigerators (its first emergency use), so I'm thankful enough that I'm giving it 3 stars despite its bugs. Mine does not work correctly in all modes, doesn't work the way the instructions said it should work.

I found some workarounds, but they're complicated, so I had to write my own instructions and tape them to the inverter -I'm pasting them below:

A) Without remote control installed:

Problem: Inverter does not work correctly with low power loads, like a transistor radio, whether or not it's in power saving mode.

1) With power saving mode enabled, it would work for about 30 seconds or so, then turn off, when attached to low-power loads like radios.

2) Even when the power-saving mode is disabled, it still acts as if it's in power-saving mode(!): it stays on for 30 seconds or so, then turns off (at least for about 10 seconds, then I think it went back on again by itself for another 30 seconds or so, but Corina thinks it stayed off), when attached to low-power loads like radios.

Cases where it works correctly: It seems to work okay only for high-power loads, over 100 watts, even with power-saving mode enabled. I've used it successfully for my electric drill and my weed-wacker-type Toro trimmer, and it takes a few seconds to come on but it works.

B) With remote control installed:

Problem: inverter does not work correctly in power-saving mode (even though I set the dip switches as instructed, five six and seven off). When put into power saving mode using remote (hold down button for 5 seconds until green light comes on remote), inverter acts up like it did without the remote control when power-saving mode was disabled (A2 above): it stays on for 30 seconds or so (green light solid on remote and inverter), then turns off for a few seconds (green light off for a few seconds on remote and inverter), then turns back on again (and turns on again even without any load attached!)

Cases where it works correctly:

When using remote, it works fine with power-saving mode disabled using the remote (orange light solid for inverter on, orange light flashing for inverter off). Turn the inverter on and off (keeping power-saving disabled) by one press on the remote button.

Summary and tips:

Without remote, works only for high-power loads (like drills, trimmer, etc.), regardless of whether inverter is in power saving mode or not.

With remote, works only with power-saving disabled (orange light on for inverter on, orange light flashing for inverter off).

If I need power-saving mode: disconnect remote, and use only high-power loads.

If I need to use low-power loads (like CF lights or small radios): keep remote connected, with power-saving disabled (orange light), and then switch the remote on by a short push (orange light turns solid).

GTMax Premium Rapid 2000MAH Micro-USB Car Charger Vehicle Power Adapter with Blue LED For Cell Phon

I noticed that my Samsung Galaxy 2 note wasn't charging in my car, charge would stay the same. Then I realized it needs a 2 amp charger. So I bought 2 of these for both of my cars and wasn't disappointed. Now it charges in no time and the white back piece glows a cool blue to let you know you have power.

Only problem is that I seldom need it because battery life is so good on the note 2.

I bought two based on the good reviews. However, with the GTMax car charger / car audio jack plugged in my phone the same time, it often generates quite loud, wired noise from the car audio speakers. This happened before the audio kicked in (when audio is on, it has no noise).

I'm NOT sure if this chargers is compatible with Samsung Galaxy S3. I have it charged my phone for a few times. It seems it charged the phone ok. But I'm still concerned if it could damage my phone in the near future.

I don't have the same noise problem with my previous smartphone with a no-name car charger.

Also note this charger has no label whatsoever for voltage/output/input information.

I'll return these chargers, just for a peace of mind.

Update 1/14/2012

My friend has a Samsung Galaxy Note 2 and the charger charged his phone ok. No loud humming noise as when I charged my S3. I noticed this charger is rated 2.0 A while S3 original charger is 1.0 A. Galaxy Note2 original charger is 2.0 A. I guess this charger is too strong for S3, and it may just good for Note 2 or similar device that requires 2.0 A charger.

I recommend you use this charger for a suitable phone. I'm just not comfortable to use it with my S3. I gave the chargers to my friend as a result.

I bump the rating up from 1 star to 3 stars.
