Title: A must have
Review: Lets see what is it and if you need it or not.....Basically what they give you is a 'batery pack' and a cable, what you do is use the batteries in your control and when u need to recharge just plug the cable in, the control will still the wireless and the cable will only charge the batery pack, since the charge is made from an USB connector, you can even plug the cable into a standard USB port in your computer and play in your xbox it will work :)But what happen if you already have plenty of these rechargable bateries ?Well use them, ok it is easier to just plug a cable, but it is wiser to don't spend money in something you don't really need if you have an alternative.
