Instructions
Connect the charging station to your Wii's USB port, or another USB power source if your Wii has no more slots open.
Disconnect the standard Wii controller battery pack and replace it with the charging station's charging pack.
Mount each controller into the charging station slot facing forward, making sure that the wrist strap does not block the charger.
Check the LED light on the charging station, which is usually a blue light for most charging stations, to ensure that your controllers are being charged.
