Measuring only 3.3cm x 2.3cm x 1.3cm it fits easily into your pocket for desperate times when you need more battery power.

The tiny aluminum gadget features a micro-USB connector that fits into most Android smartphones including Samsung, LG, Sony, Motorola, Nokia and BlackBerry.

Fuel can hold power for well over a month providing 20 to 30 minutes extra of talk time or a couple of hours standby time.

A USB cable is also not included, even though the battery itself charges via USB so you'll have to purchase one separately.

In addition, there's an on/off switch so you can reserve Fuel's power.

Fuel is available now on the Firebox website for $41.59 (£25).
