The advice is often to have a landline in the house in case there is an emergency and there's no power to charge your mobile phone.  Eton have now brought out the slimline Clipray Hand Crank LED Flashlight with USB Wind up Mobile Phone charger.  It's a must for all emergency and travel kits.  A well designed wind up light and mobile phone charger at a very affordable price.

The Carabiner Clip makes it very handy to clip on to a backpack for easy access or just to hang up somewhere handy at home ready for any emergency.

To hand power a mobile phone, all you need is a USB charger for your phone and you have instant eco power!  Caution: The wind up option will only give you a few minutes of talk time on your mobile phone, enough to make an emergency call.  It is not suitable as a day to day mobile phone charger.

Just to note that if you are trying to charge an iPhone 4 with the Eton Clipray, we have found from personal experience that you have to wind the Eton Clipray backwards (anti clockwise) first in order to get the charging symbol.

To use the powerful LED light simply crank the handle for 60 seconds at 2 cranks per second and it will give approximately 10 minutes of light.
