Eneloop Wii from Sanyo

Sanyo has teamed up with Nintendo to bring the Eneloop Wii battery charging pack for your Wiimote, ensuring that you never have to take batteries out ever again. All you need to do is place it in the charger stand (or cradle) when you’re done, and it will go straight to the charging process. It will take approximately 220 minutes for a full charge. Heck, it can even be daisy chained so that all the remotes can be charged sequentially (not simultaneously, unfortunately) from a single AC adapter. Unfortunately, the Eneloop Wii is a Japan-only product at this point in time.
