The Voltaic backpack is a mobile power source, designed to charge your gadgets without the need of being close to a power outlet. That's because embedded in the back of the bag are three tough, light weight, waterproof solar panels, which generate up to 4 watts of power.
Inside the bag is a Li Ion battery pack. As in a solar powered house, the battery stores energy so it is available when users need it, not just when the sun is up. The battery pack can also be charged using the included AC travel charger or car charger.
The Voltaic backpack has got enough power to charge most portable electronics (other than laptops) including: mobile phones, cameras, two way radios, GPS's, PDA's, even iPods. The bag is made from tough, UV resistant, 840D nylon and padded with high density foam. It weighs only 3.5lbs including the solar panels and the battery pack.
The bag includes: a set of standard adaptors for common mobile phones, a set of universal adaptors, and a cigarette lighter socket so you can use a standard car charger. A full range of optional adaptors are also available. The backpack retails for US$229.
