Nokia has upped the "how green can you get" stakes with a kit that allows users to charge their phones when cycling, the phone manufacturer said on Thursday.
The kit consists of a charger and a dynamo, as well as a holder to secure the phone to the bike. The dynamo, a small electrical generator, uses the movement of the wheels to charge the handset through a standard 2 millimeter jack, which is found in most Nokia mobile phones, the company said.
The kit starts and stops charging when the bicycle speed is 6 km/h and 50 km/h, respectively. To reach the same efficiency as the electrically powered Compact Charger AC-3, the cyclist has to pedal at 12 km/h, according to a Nokia data sheet.
Using pedal power to charge mobile phones helps users who have limited access to electricity, and also gives everyone the chance to be more environmentally responsible, according to Nokia.
The bicycle charger kit will be available before the end of the year, and is expected to cost about €15 (US$18), according to a spokesman.
On Thursday, Nokia also launched four new phones, three versions of the C1 and the C2, which can be used with two SIM (Subscriber Identity Module) cards. The two SIM cards can be active at the same time, and the second card can be removed and inserted when the phone is on, according to Nokia.
Nokia C2 will ship towards the end of the fourth quarter, and cost €45 before taxes and subsidies.
