Nokia has recently launched a kit that enables mobile phones to be charged from a kit which uses the kinetic energy of a bicycle. The Nokia Bicycle Charger Kit starts charging at walking speed (6 km/h) and stops when speed reaches 50 km/h. The total charging time varies depending on the phone and the cycling speed. For example, just 20 minutes of cycling at 10 km/h can power up a Nokia 1202 for 1 hour of talk time or 74 hours of standby time. The Nokia Bicycle Charger Kit is compatible with all Nokia phones that have a 2 mm charging interface.
The Nokia Bicycle Charger Kit is easy to install and suits many different types of bicycles. The kit consists of three components: a bottle dynamo, a charger and a phone holder. The bottle dynamo fits to the front of the bike with a mounting bracket. The charger and phone holder attach securely to the handle bars. The charger, phone holder and phone can be removed easily whenever the bike is parked.
The rubberised phone holder mounts the phone securely to the bike and protects it from the vibrations of bumpy roads. It can be mounted right in front on the handlebars so that the cyclist can see the charging progress and listen to music on the phone's speakers.
The charger is carefully designed to withstand dirt, humidity, and weather, with an ultrasonically welded case and clear coating on the electronics. The dynamo is also very robust. The phone holder comes with a transparent bag to protect the phone from dirt and humidity.
The Nokia Bicycle Charger Kit pays itself back quickly through savings on charging costs. And because you generate the electricity, there is no additional environmental impact from charging.
