    Well, it uses two AAAs, so 1.5x2 = 3 volts. USB = 5volts. Does the shuffle also accept 3 volt input? Or is there some chip inside the pack that makes it 5 volts at a lower amperage? I was thinking a 5volt regulator, however, I thought that those can only reduce voltage, not raise it.

    As far as I know, those are two completely different things. It doesn't really matter what the voltage is, one just goes faster than the other. So, the AAA batteries might only give enough power for the iPod to charge off of, while the USB power allows it to charge while playing.

    no...as far as I know you can't charge the shuffle off the battery pack, it only extends the use of it. And the shuffle plugs into the battery packs via USB port. The reason why I ask is that I'm curious, I don't intend on messing with the battery pack, I actually don't intend on buying a battery pack for it at all. However, I may buy/make a USB power supply for my car. btw, it adds up to 20 hours of play time after the shuffles batteries are dead, for a grand total of up to 32 hours of play time.
