This charger can store up to three Wiimotes simultaneously loaded werden.Der biggest advantage however is that you mitsammt the Wiimote Wii Motion and rubber sleeve can put on the charging station.
The charging time when the battery is completely emptied ca.4 hours (ohnen rubber sheath) .With rubber sheath is the loading time of about 5 hours.
It can, however, also special batteries for Wiiboard .... so be loaded.
Conclusion: I would highly recommend any charging station.
