imported it when it was 1st released,
This review is from: U Boost (Nintendo Wii U) (Accessory)
I have followed this and the Power pak since they where announced. As we all know, the Wii U Gamepad battery is...very short.
I imported this and the Nyko battery extender at a high cost. Google "Nyko Power Pak problems".
On to the Uboost, It lasted maybe a week longer than the power pak,with the same problem. Taking forever to charge and completely discharging after a few mins. I did complain to Nyko when the power back broke but the only offered to send me a uboost. So it was pointless.
I'm not alone in having issues with this item, but you know Amazon will support you if problems develops with this. BUT>
I dont recommend it myself.
