Is there some actual 'talking' going on when I plug into a computer that doesn't happen from a wall socket? I've charged the device on my work PC before, and I don't have the drivers/software installed there.
There have been several discussions on USB to wall/mains chargers. This thread
is just one of several.
I simpify charging by using both a Sony A/C charger made specifically for the PRS-505/700 and a PSP A/C charger. Yellow adapter goes through transformer and plugs directly into wall/mains. This gives a full, deep charge, in the shortest amount of time.
Hope it explains a few technical details.
