GoSun got its start building sun-powered cooking tubes. Now it's harnessing the power of the sun to do the opposite. The Chillest is a 45L cooler that can be powered via its built-in battery, an AC or DC outlet, or by its solar panel that doubles as a table. It has dual chilling zones, so it can act as both a cooler and a freezer, and also has an integrated Bluetooth speaker and bottle opener. It requires zero ice, so all the contents stay dry — in fact, it's efficient enough to make ice itself, with a powerful compressor capable of reaching temps of -4°F to 68°F, controlled by a companion app or built-in touch buttons.
