I think it is dependent on the device supplying Power
I think that most PC's give 500 ma (milliamps) max at the usb.
The Stock charger is 900 ma.
Aftermarket chargers, car and home are a mixed bag. I have a plug in charger with usb that only puts out 100 ma.. and that thing is useless, unless you turn your phone off.
I have another that puts out 500 ma and that is ok..
The stock plug in is best, obviously, but...
I have a Car Charger for my TomTom and that thing puts out 2000 ma.. and it will charge my TP from Dead in about 30 minutes, off or on....
I guess it just depends on what you have it hooked up too.
