The power bank features two USB ports (5V/1A input), so you can charge two devices at the same time when away from a power source or outlet. It works with iPhones, Blackberrys, Androids, and HTC phones. The Rose Stone also charges Bluetooth headsets, cameras, GPS devices, tablets, and more (depending on device charge requirements). 

Measuring 4 x 1 x 1.5 inches and weighing five ounces, it fits in a pocket, purse, or bag. The Powerocks Rose Stone 6000mAh costs US$69.99 and is available at www.powerocksusa.com, www.powerocks.com, and www.amazon.com .
