Like the company's prior products, the GoSun Go Solar Stove uses the power of the sun to cook your food. Unlike its predecessors, this one's small enough to fit in a backpack. It uses compound-parabolic reflectors to heat a double-walled tube that can cook up to 14 oz. of food at temps up to 500º. Its adjustable stand lets it boil water when upright, and its EVA foam exterior keeps it safe from bumps and bangs.
