Nyko preparing GamePad battery extender, doubles play time

Nyko is working on an accessory for the Wii U GamePad – known as “U Boost” – which promises to extend the battery life of the controller. Supposedly, the new rechargeable lithium polymer battery doubles the GamePad’s play time.

Amazon UK lists a November 30 release date for U Boost. You’ll be able to use the existing Wii U GamePad AC adaptor with the new battery.
