Connect one end of a USB cable into the headphone port of the iPod. Connect the other end to a high-powered USB port on a laptop or computer.
Make sure that the computer is powered on and not in sleep mode. If the status light on the top of the iPod glows orange, the device is charging.
iPod Shuffle batteries take approximately two hours to fully charge. When the status light glows green, the device is fully charged and can be disconnected from the computer.
