The Joytech Wii Powerstation provides two rechargeable battery packs and a charging/docking station for the Wii Remote controls. This eliminates the need to replace your batteries, and while you are playing with one the other can be recharging allowing you to play longer and not go through so many batteries. You just swap out the battery pack, put the old one on the charger and you are back in the game, literally.

The pictures appear that the station is powered by USB, but there are no specifications that we could find for sure. This currently is not yet available, but the Gameseek web site states that pre-ordered Wii Powerstations would start shipping on January 26th, 2007.
