So if I get a PSP cable I can stick one end in the USB adaptor and the other in the round, yellow DC socket on the device and it should charge. That shouldn't be too hard.
But does anyone know why I can't charge it from the USB socket? What is the difference between the two power sources? 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.
