solar backpack

Powerful Solar Panels: Tough, lightweight, waterproof solar panels are embedded in each bag. The panels use high-efficiency mono-cristalline cells to charge devices fast. The Backpack, Converter and Messenger produce 1.35-4 Watts, meaning 2 hour in the sun will power 3 hours of iPod play time or 1.5 hours of cell phone talk time. The Generator produces 6-9 Watts, powerful enough to extend laptop runtime by 3-6 hours from five hours of direct sun. Battery Included: All Voltaic bags come with a removeable battery pack which stores any surplus power generated, so you have power whenever and wherever you need it - not just when the sun is up. The battery can also be charged using the USB cable and the optional AC travel or car charger. Easy Connection to Devices: All bags include standard adapters for common cell phones and other handheld devices. The Generator also includes common laptop adapters. Art.
