One way is to plug it into the computer via the USB cable. That will charge the battery. But if you plug the USB cable into a USB hub, you will need a powered USB hub to charge the battery. A powered USB hub will have a power adaptor that plugs into the wall. Bypassing the hub and plugging it directly into the computer should always work if the computer is powered up.
