The SolarRoll has officially taken its place as one of the most talked about products. The proof, though, is in the remarkable performance. The waterproof SolarRoll has given sea kayakers the power to photograph their voyages from the far reaches of the planet. Ideal for powering satellite phones, members of expeditions worldwide pack the SolarRoll in place of expensive extra batteries that don't offer much relief in the form of weight. This product is ideal for running cell phones and charging digital and video cameras.
