Keep your 3DS™ powered for up to twice as long with the Charge Base from Nyko. The Charge Base comes with the Nyko Power Pak+, a double capacity Lithium Ion Polymer battery, designed specifically for the 3DS and a custom charging dock that allows for easy charging and storage of the handheld. Once installed onto the back of the 3DS system, the Power Pak+ battery provides double the capacity of the stock battery while also giving the system a textured grip and de-bossed finger rests, perfect for extended game play sessions. The included charging dock is powered by the stock AC Adaptor that comes with the 3DS and allows for convenient storage and charging of the system. No excess cords, plugs or adaptors, just drop and charge. The Charge Base is everything you need to store, charge and keep your system powered for twice as long.
