The ezGear powerPlay Do is the Ultimate charging solution for your Wiimote. With the powerPlay Duo, you can use one battery with your Wii, while the other battery sits in the charging station. When your first battery runs out, just swap them and keep playing.
The specially designed powerPlay dock can charge the powerPlay battery while in the Wiimote or on its own. The powerPlay conveniently plugs into the USB 2.0 port on the back of the Wii so it does not use any extra power outlets.
