Devotec Industries, a UK-based company is going to launch what they claim is the world’s smallest emergency rechargeable phone charger named Fuel on Kickstarter. The phone charger Fuel is just 1.3-inches in size and it is made of die-cast aluminium. It can be carried even on a key ring. The fuel contains a 220 mAh Li-ion battery which is said to provide around 20 – 30 minutes extra talk time, or up to a few hours more standby, depending on how you use your cell phone.
The Fuel also includes a standard micro-USB port which is compatible with most of the smartphones existing in the market, but unfortunately iPhone owners are currently left out of this one, though Devotec does appear to be planning the release of a version with an iPhone 5/Lightning connector at some point in the near future.
Once charged, it can retain the charge for anywhere between a month and three months before needing to be charged. There are three LEDs provided on the outside of the case, which indicate the current status of Fuel. It also consists a switch to turn the Fuel Micro Charger on and off, keeping the battery from needlessly discharging when not in use.
Here is the complete specification of Fuel:
