Juice Bags integrate a specially engineered thin-film solar panel into a backpack. The panel is flexible and will shape much like a normal canvas backpack would. Delivers over 6 Watts of power to drive your handheld devices. Claims to charge a typical device in 2 to 4 hours in direct sunlight. The canvas is made from recycled plastic drink bottles.
