Maximize your sun-supported power production with the Nomad 20 Solar Panel, Goal Zero's largest foldable, fully portable charging device. Built for charging all your essential electronics, this panel directly restores your camera, GPS, or laptop batteries via the USB port. What that means is that this panel charges your electronics when it's in the sun, but the panel itself doesn't store power (to store power, use this panel with one of Goal Zero's portable power pack batteries, sold separately). At less than three pounds, and with a folded size that's just slightly larger than a standard piece of paper, the panel is awesomely mobile. Pair it with a Goal Zero portable power pack battery (it's most ideal with the Sherpa 50, Yeti 150, and Escape 150), and you can store power to illuminate your tent and crank out the nighttime tunes. It's an energy source for the long-range backcountry and the barely off-grid.
