The Voltaic backpack is a mobile power source designed to charge your gadgets without tying you to a power outlet.
Embedded in the back of the bag are three tough, lightweight, waterproof solar panels which generate up to 4 watts of power. It holds a Lithium Ion battery pack to store energy for when you need it, and can be supplemented by an AC adapter or a car charger, which are both included. A full range of optional adaptors are also available.
Wires from the battery pack run through the bag to each of the pockets so you can keep your devices charged and ready to go. The Voltaic backpack is powerful enough to charge most portable electronics, including: mobile phones, cameras, two way radios, GPS’s, PDA’s, even iPods (but it doesn’t cover laptops).
Simple, stylish and priced at only US $229, the Voltaic backpack is the perfect fit for the tech laden urban adventurer.
