Unplugged mobile power goes ultimate.
With enough power to top off your smartphone up to 4 times or your tablet once, travel abroad, spend a night on the town or do something more mundane – all with confidence your gadgets won’t die.
Designed for portability, this powerful bar-shaped battery slips easily into your bag for use when you need it on the go. No need to worry about it bouncing around in there, the rugged, high-grade plastic outer shell takes in-bag abuse with ease.
Not just powerful and portable, but also delightfully detailed. Check the remaining power on the four-LED power meter with a click of the power button. We’ve also included 3 broadly-compatible adapters and 2 cables. Pack the combo in the travel pouch and have all you need for mobile charging.
For optimal use.
