Go Power! GP-SF-1.5 SUNfilm 1.5 Watt Solar Panel

I recently purchased this charger to keep my car battery from dying when I do not use it for a week or so. I have other Go power products and I have had good sucess with them. I unfortunately had my battery die on me when I left my car for a week without starting it. I figured this might work instead of buying a new battery. So far it has worked. I plug it into my cigarette lighter and put it on the dash whenever I am going to leave the car for more than a day. I have tried it after a week of not running the car and the car still started. I would recommend this product.

However the cord to the unit is so flimsy that it broke. About three months ago so it really didn't last long. While it worked it worked well but it really is not worth it because it is made horrible well. The cord is pretty important no?

Works like a charm. After a month of exposure, I am seeing some small degradation bubbles in the cell. Not a big deal, will probably last over a year. For the price, that is great.

Its OK, does not work unless your battery is completely charged and good. will not charge a low battery, which is what i needed, but will work to keep my mower/tractor charged during the winter months without using an extension cord.

Oh boy... Let me tell you my story:

I don't drive my car much so I figure these things would keep my battery in good shape.

I bought two of these, figure if it works, I'll give one to my friend.

My battery on my car still works fine, just low since I don't drive it much.

I installed the device, 2~3 days later, when I try to start my car, it won't stop at all and no power to the car whatsoever, if I didn't install this thing, my car would still start, this thing not only didn't charge my battery, it did the opposite and drained my battery at a faster rate than it's natural 1% per day drain.

You thought maybe the product is DOA? Well, I installed the 2nd one since I bought two, 3 days later, still no power.

Conclusion:

This thing does not charge a 2008 Toyota Yaris, not only it doesn't charge, it also drain possibly harm your battery, I'll find out later today when my friend comes over for a jump start with a jumper cable, if it still doesn't start, then this product killed my battery when my battery was fine before I installed this, I really hope this thing didn't kill my battery.

Since my car is a pretty typical common economical car, if it doesn't work for my car, it wouldn't work for many cars out there, so beware. I would recommend those portable jump starter device, those are similar to the way you use a jumper cable and jump start with another car, except it has a battery to it so you don't need another car to do it.
