Mad Catz Wii Fit Battery Pack

Really good for Wii Balance Board owners as it eliminates the need of finding4 extra AA batteries whenever power is low. However, I find that that USBcharging is way too slow and would've preferred a wall charger.

This battery pak will guarantee you 20 hours of full on gameplay for the Wiibalance board accessory. I highly recommend it among Wii balance board owners.Certainly beats buying a full packet of new batteries every now and then.
