Nyko Nyko Xbox One Modular Power Station With 2 Rechargeable Batteries

It is a USB-powered battery charging dock that attaches to the side of the original Xbox One console. The station comes with two 1000 mAh rechargeable battery packs for Xbox One wireless controllers. Hidden indicator lights display the charging status of the batteries. The modular design means no extra cables are needed to power the unit, as it uses the console's side USB port.
