Next up in our countdown of the Hottest 100 gadgets on the planet is the Powertrekk Fuel Charger
What? Charge your phone using water? It might sound like madness, but it’s real. All you have to do is open up one end of this charger, pour in one tablespoon of water, then plug in your mobile.
And hey presto, the water powers a fuel cell which provides charge to your phone. Unlike solar-powered devices it provides instant power, and doesn’t rely on good weather.
Not only that, it’ll charge anything that uses USB, so your tablet, laptop, camera… anything is sorted. All you need is a tap, or water bottle. A true lifesaver.
