Apple iPad will be charged when attached to a computer via a standard USB port (most PCs or older Mac computers), but only when it is in sleep mode. This is not a good way to charge it because you cannot use iPad on the same time. Officially, 10W power adapter is the only tool to charge iPad while using it for PC users. So how to charge Apple iPad on PC?
