Stop wasting money and time buying disposable batteries that only work once before going to the landfill.
These amazing batteries work like any other AA batteries, but when they're low you simply flip the top open and recharge them anywhere via any standard USB port (your computer, phone charger brick, car USB port, power bank, airplane seat, public charging station, etc., etc.). The USB plug is built in, so there are no cords to mess with or lose either!
Size: AA. 2 rechargeable batteries per pack. NH-AA 1.2V 1450mAh.
