With a 3000mAh capacity that makes other 18650s look like pipsqueaks, Samsung's 30Q is a never-ending well of power. You'll recharge this massive power tank less often than any other battery you've used in the past. Free yourself from the USB cords and wall chargers! For powering electronics at lower amperage (15-20A), you'd be hard-pressed to find a finer battery.
