Product Description:
Complete with a charging cable and rechargeable battery pack, the Xbox 360 Play and Charge Kit is all you need to juice up your Xbox 360 Wireless Controller?even in the midst of battle.

Rating : - Great unit, Great Price
This is a must have with your 360 and a controller. And in black to match your Elite controllers.

You can plug it in via USB to your Xbox 360 and charge the included battery pack while you play your game.

You can also remove your battery pack, and plug the cable directly to your 360 for wired gaming (so your controller won't shut off while you are in the middle of that hired driver Forza race.

This charges via any USB port on your 360, your computer, your cable box, or your dog (if he has included USB hub).

I recommend buying one of these, then buying the Quick Charge Kit. Then you'll have 2 battery packs, the quick charge dock, and a USB charge cable.
