I charge all of my ipods and BB's off the same chargers. Some will just charge slower than others. It all works off USB cords and there's no way that anyone could tell me that every USB port from all computers put out the same amps/watts whatever. 99% of phones, ipods, whatever will control the input from the charger. Some will just charge slower or faster than others. I know that motorola products only like to be charged off of computers or motorola branded chargers. Something written into the code won't allow them to be charged off generic usb chargers.
