Great looking and lightweight, this super-cool backpack is fitted with waterproof solar panels embedded in each bag. The panels use high-efficiency mono-cristalline cells to charge all your electronic devices quickly and efficiently. The Backpack produces 4 Watts, which means that just one hour in the sun will juice up 3 hours of iPod play time or 1.5 hours of cell phone talk time.

All Voltaic bags come with a removeable battery pack which stores any surplus power generated, so you have power whenever you need it - not just when the sun is out. The battery can also be charged using the USB cable and the optional AC travel or car charger. Another cool feature of this solar backpack is that the shell uses 600D fabric made from recycled PET (soda bottles), a material which is durable, water resistant and light weight.
