The Energy Pak installs conveniently on the underside of the Balance Board and features a unique AC Port Relocator that allows users to easily play with the board and charge the battery simultaneously, without ever having to remove the Pak or turn the Balance Board over. An easy-to-read LED charge light indicates the charge status of the battery, letting the user know when it is time to recharge, and when the charging cycle is complete. The Energy Pak can be quickly charged with the included, detachable AC adaptor, and provides up to 20 hours of playtime per charge.

"It is difficult enough trying to keep up with a regular fitness program without the hassle of swapping out alkaline or other rechargeable batteries," said Chris Arbogast, Director of Marketing at Nyko Technologies. "Like all of our charging solutions, the Energy Pak is as easy to use as it is functional. Users will be able to recharge the Wii Balance Board while in use or in between gaming sessions, all without ever needing to flip the board over to switch out battery packs."
