Across console generations, Xbox controllers have always used AA batteries instead of a built-in rechargeable one. It has its pros and cons, but Otterbox has found a solution that combines the best of both worlds. The company’s Xbox Battery Pack gives you two rechargeable packs that you can hot-swap. A third tiny battery clips into the controller via a cage. This battery stores up to 30 seconds of power, keeping the controller on while you swap packs.
Each battery pack lasts up to 10 hours per charge. The Xbox Battery Pack also comes with a charging dock. a cage that works with the Xbox Series X or S controller, and a cage that works with the Xbox One controller.
