Whether you're hiking the Appalachian Trail or fishing the bayous of Louisiana, Goal Zero has you charged with the Nomad 7 Solar Panel. When it's folded, it's smaller than a standard sheet of paper and easily fits in most messenger bags or backpacks for easy transport. When you need to power your smartphone or tablet, simply open it up and expose the monocrystalline cells to the sun's rays and connect the device you wish to charge. It's capable of charging handheld USB devices and 12V gear with nothing more than the sun. When you're done charging, simply fold it back up with the magnetic closure, put it back in your backpack and away you go.
