Devotec Fuel Micro Charger is the smallest emergency phone charger, and its 220 milliAmp hour battery is designed to give you around 20 - 30 minutes extra talk time, or up to a few hours more standby, depending on how you use your cell phone. Perfect for when you have had an unexpected delay, or haven't been able to fully charge your phone, and you need to make a few calls, send a work email or use your GPS and maps function to find your way home. Tiny Tiny Tiny The Fuel Micro charger is the world's smallest cell phone recharging device. And it is absolutely tiny- just 1.3 by 0.9 by half an inch. It's so small that it can sit easily on your keyring, you can slip it into the 5th pocket of your jeans, or even have it hanging off your cellphone. The Devotec Fuel Micro Charger is an emergency back-up solution. The Micro Charger is fully rechargeable, and is able to keep it's charge for at least 1 month before needing to be recharged (our calculations suggest closer to 3 months, so we are being conservative!) How it works Charge up the Fuel Micro Charger from any AC micro-usb wall plug such as those for an Android Phone or Kindle, or a USB - Micro-USB Male cable. Then just put it in your pocket, on your key chain or in your car and forget about it. To Use: Turn the power switch on and plug into your phone, the same as you would your charger. Your phone will start to recharge straight away. See what BBC said about Fuel here https://www.youtube.com/watch?v=MP4f_mjwGI0
