  • Rapid Charging Mobile Electronic Device Battery Case
    Publication number: 20160043585
    Abstract: A rapid charging battery case for a mobile electronic device that comprises a protective casing, a fast charging battery, and a charging circuit. The protective casing forms a snug fit between the casing and the mobile electronic device protecting the mobile electronic device from impact forces. The battery case includes a power jack input port for receiving a 3.5 mm diameter power supply jack that charges the fast charging battery in under fifteen minutes. The internal battery of the mobile electronic device is charged simultaneously with the fast charging battery.
