The Falcon 21 is a lightweight, foldable solar panel designed to charge laptops and netbooks (only under 40 W), tablets, smartphones, GoPros, GPS devices, and other 5V and 20V devices using the power of the sun. The Falcon 21 is made from extremely durable fabric and can charge up to two devices simultaneously (one via USB and one via DC). SunPower's highly efficient monocrystalline cells generate 25-35% more power than conventional cells—meaning your devices will never have to run out of juice. The panel's IPX4 rating means it can withstand splashes of water from all directions for up to 5 minutes, and thanks to the handy metal grommets and included carabiners, the panel can be easily attached to backpacks, tents, bike bags, and more for convenient charging.
