Rally 7413 200W Cup Holder Power Inverter with USB Port

This product does all that it was advertised to do and has plenty of outlets--2 standard wall outlets, a car outlet and a USB outlet. You can run a cell phone charger, a satellite radio and your MP3 player off of this power inverter. The one glitch, it has to be turned off and on--in other words, when you plug in a device, it will not start charging right away--you must flip the power switch back to off and then on again. Don't assume that just because you have it turned on that it is actually charging. It is a small inconvenience, but otherwise, the product works great!

I wanted an inverter to power my laptop charger. Didn't want to permanently install one, but didn't want one sliding around on the floor or dash either. This design fits great in one of the center cup holders and plugs in the lighter socket nearby. Has a USB plug to charge your Iphone or Ipod, TWO AC outlets, and a built-in lighter plug so you can still use another 12volt device without having to unplug the inverter. It isn't completely silent, but at 200 watts the fan is necessary. I was a little disappointed in how the fan was attached inside the vent opening it pushed into the housing with very little pressure had to take the housing apart to re-attach it with some superglue.

I received this product this evening, and I have to admit it looks great. I was really excited to try it because it seemed far better in construction than some reviews have said. I took it out to our 2003 Pontiac Montana. We power stuff through the utility & cigarette lighter adapters all the time. First problem: It would not stay put in the socket, but instantly popped out. I tried numerous times to get it to stick. Finally, I just decided to hold it in and see if I could power it one. No luck. Just plugging the adapter into the vehicle blew the fuse.

"Hmm, must be a fluke, I thought, I'll try it in my Camry." Took it over to the Camry, plugged it in, and before I could even try turning it on, my radio went dead -and the power port with it. It had blown the fuse in the Camry, too. And this is with nothing plugged into the inverter, mind you!

It's going back. Totally unreliable, and so far all it's done is blow fuses.

I have been using this power inverter for the past couple of weeks and could not be more pleased with it. It performs exactly as I would expect it to. The USB and 120v outlets work perfectly. There is also a lighter adapter, so your radar detector, GPS, etc. can still function. Or, you can get an extra adapter and convert this into an additional USB port(s) if you need to. Because it has a ground fault interrupter circuit, you need to turn it off and on again each time you start your car (if you don't, it will shut itself off automatically). A couple of other reviewers complained about this, but this is a great feature to have in a small priced item. After completing this review, I will be purchasing a second one for another vehicle.

First, I'm very happy this power inverter has a 12V female connector allowing me to continue having a 12V power port available. This is constant whether the power inverter is on or off. The USB power port is also constant. The only need for the power inverter to be in the "on" position is for using the 110V outlets. They (either individually or simultaneously) can handle a max of 200W with a spike (1/3 of a second) of 400W. I've only used them with a little more than 100W so far without any problems.

Second, the bad, really, not so bad...The fan does make noise but only when the power inverter is switched on to use the 110V outlets. This is acceptable and necessary for cooling the unit. Since using the 110V outlets may be rare anyway and when being used while driving, the road noise, A/C and talking make the fan noise virtually unnoticeable. Another thing is the protective caps are a bit difficult to remove, especially the USB cap. This cap can be left off/open for regular use.

As for the power inverter sitting securely in your cup holder depends on your cup holder. In my case, the unit was not very stable where I used foam around the bottom to give it a snug fit in my cup holder. Foam also allows air flow to the fan intake vents. I never received a "rubber chunk" as another reviewer stated.

Overall, I am very happy with this power inverter...With all these functions in my vehicle, it's like having a car office.
