Whether you just want to do your bit for the polar bears or you’re stuck out in the middle of nowhere with a dead battery, this solar powered laptop charger is the perfect solution for topping up your power. It’s the modern equivalent of making fire.

The 20000 mA/H capacity solar panel can charge standard 5V devices - like your mobile phone or iPod - all the way up to 16-24V kit so it can even top up the most power hungry of laptops. If you’re pushed for time you can charge it up from the mains in about three hours. If you’d rather go for the planet hugging option instead, then you’ll need to leave it out to soak up the rays for a good eight hours.

It comes with 11 different laptop adapters and 13 mobile phone plugs, so you should find the one you need in there. It even packs an ultrasonic speaker to ward off mosquitoes and other winged pests while you’re camped out in the middle of nowhere.
