The sun's energy accumulates in each item's “battery bank” and is dispensed to the device as needed. The battery bank is an integral part of each bag and can be used to charge a wide variety of mobile devices. Adapters for nearly any kind of device, from iPods to mobile phones, are included with each bag. In direct sunlight, each bag's three panels absorb 1.5 watts of power and charge the battery bank within three to four hours.
