The Levels Solar Backpack not only carries all your devices but charges them too. A 4.5-watt, black matte-finished solar panel maximizes energy absorption from the sun for conversion into an electrical current. With it, you can extend the recording time of your GoPro battery while you’re sitting on the chairlift, charge your tablet while you’re lying on the beach, and give your smartphone more juice while you’re hiking. The Levels Solar Backpack can add 18.75 percent power to most smartphones with just one hour of sunlight.
Inside, you get an adjustable sleeve to hold your water bottle and a padded sleeve for a laptop up to 17 inches in size. The main compartment holds other items such as books and clothes, and a bungee cord on the exterior secures additional belongings. For charging items, there are 8-Pin, 30-Pin, micro-USB, and mini-USB adapters. The Levels Solar Backpack retails for $150.
