For whatever reason, Microsoft still doesn't ship its Xbox controllers with rechargeable batteries. This, combined with the high price of their official solution, has led to a robust market for third-party solutions. Otterbox may have just introduced the best one yet. Their Power Swap kit replaces the battery door with a quick-release frame that holds hot-swappable battery packs that last for 10+ hours and juice up on a separate charger. The package comes with battery cages for both Xbox One and Series S/X controllers, the standalone charger, a USB-C to USB-A charging cable, and a reserve energy cell that eliminates the need to resync when swapping batteries.
