For extended off-grid life, most adventurers traditionally turn to a petrol or diesel generator. But generators are noisy, dirty and smelly, which kind of ruins your ‘back to nature’ vibe. They also come with the hassle of regular maintenance, the risk of spilt fuel and the (literal) headache of noxious fumes. All of which makes Goal Zero’s Yeti portable power stations complete game-changers. You can basically think of the Yeti as a power bank on steroids, delivering clean, quiet and fuss-free electricity.
