If you’re venturing into the back of beyond, off-grid power provides a vital link back to civilisation – not just useful for sit reps and other regular updates, but essential just in case the unthinkable happens and the proverbial hits the fan. Your options are basically a) to carry bulky batteries around, or b) to harness power from the sun. It’s an obvious choice in theory. But the reality is that many solar technologies are delicate, unreliable and unwieldy. Not the Goal Zero Boulder series though. As the name suggests, these solar panels are rugged, durable, and rigid. As the name perhaps doesn’t suggest, they’re also lightweight and practical. Made from strong tempered glass housed in an aluminium frame with added corner protection, they’re suitable for temporary or permanent installation. They’re also equipped with an integrated kickstand to ensure an optimal angle to the sun, and plug straight into a portable power pack or power station to charge your devices, day or night.
