Voltaic Systems 1001 Solar Backpack, Silver

• The Voltaic 1001 solar powered backpack is built tough for use as a weekend hike bag or as a large daypack. There are pockets and wire channels for multiple electronic devices and 1,850 cubic inches of storage space. • The solar panels are waterproof, scratch resistant, and UV resistant. They use ahigh efficiency monocrystalline cell. The three panels operate independently to generate up to 4 watts of power. This is double the power of typical solar chargers and enough to charge most portableconsumer electronics (other than laptop computers). See typical charging times listed below. • The substrate is an aluminum / plastic composite, specifically designed to be strong and lightweight. They can easily stand up to typical outdoor use including being dropped and leaned on. • The panels are mounted in a flexible fabric sleeve. They articulate with the bag, which means it doesn't feel rigid or restrictive. Even if you manage to break one, which would probably take a conscious effort, they can easily be removed and replaced.
