The Energizer Power & Play Charging System for 360 allows up to two controllers to be charged simultaneously. Charging time is approximately two and a half hours. There is one caveat, batteries are not included and you will need to own a rechargeable battery pack made by Microsoft or use Energizer rechargeable batteries. All other rechargeable batteries and battery packs may or may not work with this system.
