How many amps does this charger kick out, do you know?
It seems to give out 950. my Gnex (personal phone) couldn't measure that cause of how Samsung makes phones.
I can tell you that I have tried at least 5 of the current top car chargers, nothing could compare.
AOKP and the stock rom liked it. Stock android roms tend to charge at half speed, on chargers that have a USB port (and charge/sync wire)
