Global Satellite USA launches the Voltaic Solar Backpack, a 4-watt solar powered weekend storage bag, ideal for charging PDA's, cameras, cell phones, satellite phones and iPods. Embedded in the outside of the bags are lightweight, tough, waterproof solar panels. One hour in direct sun will power more than 3 hours of iPod play time or 1.5 hours of cell phone talk time. All Voltaic bags come with a custom 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 packs can also be charged using the included AC travel charger or car charger, making them just as useful on the grid as off. All bags include standard adaptors for common cell phones and other handheld devices, wherever you are traveling in the world. Even without an adaptor, you can charge most devices with a standard car charger or USB charger. The bag comes in silver, charcoal, orange and green. There is a removable waist strap, adjustable phone/MP3 pouch on the shoulder and a fully padded laptop sleeve for a 17-inch laptop. Providing 4 watts of power, this solar bag does not power up a laptop, but there is a larger bag in the range that does. For extra comfort, there is high density padding in the shoulder straps and back and mesh backing material for better air flow.
