what is the difference on your ipod a USB 2.0 cable and a USB power adapter. Or even if there is a diifernece.
The USB 2.0 cable supplied with the iPod can be used to charge and sync the iPod. The cable can charge and sync when connected to a computer. The power adaptor is for charging the iPod through the SAME USB CABLE which is supplied with the iPod through a normal power outlet, this is useful if your USB ports are occupied or you are travelling without your computer.
the power adapter is so you can charge it off of a regular outlet rather than having to have a computer handy to charge it through the usb port. i recommend getting the power adapter, i have it and its good
