The Voltaic solar bags are solar chargers designed to charge virtually all handheld electronics.
Powerful Solar Panels: Embedded in the outside of these solar chargers are lightweight, tough, waterproof solar panels. The new Generator produces up to 15 watts, powerful enough to fully charge a typical laptop from a day of direct sunlight. No other solar bag can do this! The smaller bags produce 4 watts of power so 1 hour in direct sun will power over 3 hours of iPod play time or 1.5 hours of cell phone talk time.
Battery Included: Bag comes 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.
Easy Connection to Devices: Includes standard adaptors for common cell phones and other handheld devices. The Generator also includes common laptop adaptors. Even without an adaptor, you can charge most devices with a standard car charger or USB charger.
