These are AA-sized lithium rechargeable cells with a USB-C port built into each battery, so you charge them with a cable instead of a wall dock. Each cell holds 2,800mWh, and the included splitter cable charges all four from one USB port. Built-in LEDs show charging status on each cell. They suit people who want to skip a dedicated charger and stop buying disposables for controllers, flashlights and remotes. Against standard NiMH rechargeables, they trade the higher mAh figures of NiMH for cable convenience and a lighter kit; NiMH still wins on raw capacity per cell and on price per cycle for heavy users.
