T-Mobile Universal Micro-USB Car Charger w/ USB PortProduct Review (submitted on December 18, 2012):
The first one I got was a turkey. I contacted customer support and they had a new one for me within a week without any hassles. The replacement works just fine. It puts out good power without my phone complaining of an insufficient charge. There is a little bit of static that comes through while hooking through the car stereo via the headphone jack on my phone but it's not terrible.
