What’s better than a carabiner clip? Maybe one that comes with a battery to charge your USB powered devices like a smartphone. The Powerbiner has a 3000mAh battery inside that adds 11 extra hours of video time to your phone. It can also hold 132lbs of load. The power bank has overcharge and short circuit protection.
You can mount the Powerbiner on a bike, tend, tree, or anywhere else. It works with anodized aluminum housing, rubberized grip, and charge indicator light.
