Excellent value, more flexible than description suggests
on February 17, 2012
I bought this to charge my Kindle and LG cell phone in the car. It is in no way limited to charging the products listed in the description. What it does is to convert the power available in a car into the power available at computer USB ports (but, of course, with no data). A sticker on the item says "5.0 volts at 1000 mA". I measured the voltage at 5.25 volts, but that's OK. As to 1000 mA, this is surely more than anyone is going to need and I don't think I'd try to draw that much current in case the thing heats up (for the price, it must be just a linear regulator and the voltage difference between the car and the output just produces heat proportional to the current you draw). Also, the connector is a full-size USB type A jack, not a Mini-USA jack as the description would suggest. I'm using the cable that came with my Kindle. The device is solidly built, although very light, and plugs firmly into the car. The USB connection is a bit tight, but I can't see any problem with that. All-in-all, I'm very pleased. It was delivered by air-mail directly from China but arrived in two weeks, well before the promised date.
