On a side note, this phone simply doesn't get hot, even plugged in with a heavy load. It's truly a "cool" phone. And plugged into the car, it gains fairly rapidly on the battery charge percentage, even under heavy load.

You can charge it with that one, by the way. As long as it's 1 amp or lower, and 5 volts, it's fine. Just note that the lower the amperage is, the slower it will charge (and once you get below ~500ma, you may only break even, that is, not even charge).
5 v and 1000 milliamps
