The Beacon Box Battery is a waterproof, crushproof, solar powered phone case. The Beacon Box is an actual container that protects your phone from the elements and charges your phone while protecting it. It combines a first-of-its-kind combination of charging, solar, lighting, and waterproof technology. The Beacon allows for storage of two typical mobile phones, 3 USB charging ports that can all be used at same time, and storage of power from a Polymer lithium ion battery. The 15,000 mAh battery is always charging when placed in the sunlight. The solar panel has a 17% conversion rate, so it is always charging, even on the go.
