SP-Gadgets Power Bar Duo GoPro HERO Charging Station

The SP-Gadgets Power Bar Duo GoPro HERO Charging Station is a mobile charger that can hold two HERO3 / HERO3+ batteries and features a 12Wh internal battery for use in the field. When working from AC power you can charge up to three HERO batteries at once. Two in the charger and one in the camera via USB. When AC current is not available the internal battery has enough juice to fully charge two HERO batteries. The internal battery takes about four hours to charge fully. The Power Bar Duo will change any GoPro batteries first before recharging itself. On the road the internal battery in the Power Bar Duo can also serve as a backup power source for smartphones, tablets, and other devices that feature USB charging.
