A:Answer Thank you for your inquiry! Yes, the Insignia™ Play + Charge Kit for Xbox Series X | S is designed to charge your Xbox controller whether it is turned on or off. When the controller is connected to the Play + Charge Kit via USB cable and plugged into a power source (such as your Xbox console or a USB wall adapter), it will charge the controller's battery regardless of its power state.
This feature allows you to keep your Xbox controller charged and ready for use whenever you need it, whether you are actively playing or when the controller is powered off and not in use. It's a convenient way to ensure your gaming sessions aren't interrupted due to a low battery.
