I think this is the first time a bicycle charger has ever been used strictly for cell phone charging purposes.
The Nokia Bicycle Charger Kit can charge your phone as you ride your bike. It comes with a bottle-dynamo (similar to the ones used to power a bicycle light) and a cell phone holder that can be attached to the handlebars.
In order to use the charger, cyclists will have to maintain a minimum speed of 4 mph; however, this doesn’t mean you need to pedal for hours on end. Cycling at 6 mph for 10 minutes will charge your phone with enough power to talk for 28 minutes or for a standby time of 37 hours!
It should be noted, though, that charging times will vary depending on the cyclist and the type of phone. Oh, and this charger will only work for phones that have a 2 mm charger jack.
The charger kits will be released in Kenya first for approximately $18 and then will become available worldwide later this year.
