Voltaic Solar Bags
The Voltaic solar bags are mobile power generators, designed to charge your devices without tying you to a power outlet, which makes them ideal for traveling. 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. They provide enough power to charge a cell phone, ipod, pda or camera, but unfortunately not enough for a laptop. Thinking in the right direction.
