This innovative Piggyback Power Pack is the first power bank of its kind that's portable. Your custom full color artwork is shown via a Brightech LED box on the front. The art is illuminated as your phone or other device charges. The front (including the imprint area) has a mirror finish when charger is off. The back has 12 silicone suction cups, which lets it stick to the backside of your phone, computer or any hard surface. The battery's capacity is 2200 maH, with an input of 5V/500 ma and output of DC 5V/1A. It uses a micro USB cable (included) and charge completes in 5 hours.
