This battery pack is designed specifically to fit the Xbox One controller. It features a capacity of 650mAh. which is enough for up to 6 hours of continuous gaming. Additionally it can be used while charging so when it gets low just plug it in and play on!
Unlike the Playstation® 3 controllers which can only be charged when plugged into the Playstation system this battery pack can be charged from any USB power source that is capable of putting out at least 200mA of power which includes almost every USB port charger and external battery charger ever made.
The battery pack uses a USB micro-B connector for power and comes with a 19" USB A male to USB micro-B male cable.
Note: For best results and the longest battery life this battery should be fully charged and discharged about 3-6 times before doing a partial charge or simultaneous play/charge.
