Does car usb charger work for all usb powered devices?
I have a Sprint car charger with 2 USB ports and I was wondering if that will be compatible for all USB powered devices like GPS, iPhone, tablets, etc.
It should be ok for *most* devices, but tablets may be a problem. Tablets usually require over 2 amps of current, and not all USB chargers are able to provide that. The GPS and iPhone should both charge fine.
The package that the charger came in may have the amps rating somewhere on it. 1 amp is fine for most portable devices, but Tablets will require 2 or more amps.
It will be ok for all the items whoes amp below 1amp
