Power collection, storage and distribution in remote environments continues to be a major product category at OR. The Jumper Quad+ from EnerPlex caught the eye of quite a few military users because it can be used to recharge AA and AAA batteries in the field as well as serving as a battery pack in its own right.
The Jumper Quad+ features a 5,000 mAh battery with a 2 Amp output via USB port.
Very pleased with my EnerPlex Jumpr Slate 10,000 mAh powerbank. Thin enough to slide next to my backpack frame sheet.
