We don't know if Fuel really is the world's smallest phone charger, but it's definitely the most minuscule we've seen so far. Measuring just 1.3 x 0.9 x 0.5 inches, you can literally carry a bunch of these on a shirt pocket without any problem. And, heck, even one on that little coin pocket in your jeans.
Because of the size, it won't be able to give your phone a full charge the same way the Exovolt or the iGeek could. Instead, this is strictly for emergency use, giving you a quick hit of power to make that important phone call, send that urgent email, or just figure out where the heck you are while you're on the road.
If Fuel isn't the tiniest phone charger in the world, we bet it can at least compete for being the cutest. Seriously, it's clad like a miniature jerry can holding a load of petrol ready to pour into your smartphone's empty tank. A 220mAh battery sits inside the die-cast aluminum housing, carrying enough juice to give your phone an added 30 minutes of talk time. It can hold charge up to a month, so you can keep it on standby for use when the moment you need that extra dose of power eventually comes. Features include a power switch, three LED indicators, and a microUSB-only connector -- sorry, iPhone users, not for you.
Want one? The Fuel is available from Firebox, priced at £24.99.
