The solar bags are mobile power generators, designed to charge devices without tying to a power outlet, which makes them ideal for traveling. Just plug a standard car charger into the bag and recharge most small electronic devices including: cell phones, cameras, two way radios, PDA's, and MP3s. If we don't have a car charger, the bags come with a set of 11 standard adaptors for common cell phones and other devices. It also consists of full range of optional adaptors. Embedded in the outside of the bags are three lightweight, tough, waterproof solar panels which generate up to 4 watts of power. This means quicker charge times.
Included with each bag is a Li Ion battery pack which stores any surplus power generated, so it is available when you need it - not just when the sun is up. The battery pack can also be charged using an AC travel charger or car charger (both included). This makes the voltaic bags just as useful on the grid as off. The solar bag is shown in the fig
