A:AnswerXbox Series S/X controllers use replaceable AA batteries by default. This kit includes a rechargeable battery with USB-C charging cable. If you don't mind swapping out batteries this isn't necessary, but if you'd prefer to just recharge your controller this is the way to go. For what it's worth, Xbox has been doing this same concept since the Xbox 360, and in my experience these kits are worth the cost.
A:AnswerThanks for asking! Yes, this product includes both a Xbox rechargeable battery and USB-C cable. It is designed for use with Xbox Series X/S controllers.
A:AnswerWe're sorry there's an issue with your rechargeable battery. The problem could be with the USB-C cable, your controller, or the battery itself.

A:AnswerThank you for your question. If you have a rechargeable battery from the Xbox Play & Charge Kit for Xbox One controllers, it will work work with a Xbox Series X/S controller. As you mention, you will need a standard USB-C to USB-A cable to connect it to your Xbox.
A:AnswerNo, you have to leave it in to charge. The charging cable plugs into the controller, not the battery. You can also play without the battery and the cable can power the controller
A:AnswerI have an Xbox one controller with Insignia battery pack. I tested it and yes, the Xbox one battery pack works on my new series x controller and the USB-C charges it. So yes!
