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. Take the 500X model, for example, which delivers 505 Watt-Hours of lithium power and the latest fast charging technology in a compact, ultra-portable design. Whether you’re headed out for a few days or the whole week, it’s the perfect power solution to keep your essentials charged from door to destination and back again
