Nokia is recalling an estimated 14 million cell phone chargers the company says might be defective and could cause users to get shocked.

The Finnish mobile telecommunications giant said it found the defect through its own quality control program and has not had any reports of any incidents involving the chargers. The problem with the chargers, Nokia said, is that the covers can come off and expose the internal components.

The U.S. Consumer Product Safety Commission, the normal conduit for recalls of this type, was not party to this announcement and a spokesman for the safety agency did not immediately have a comment on the recall. It is not immediately clear how many of the recalled chargers were sold in the U.S.

Nokia is offering anyone with the affected chargers a new charger in exchange for the recalled ones. Nokia has a web site dedicated to the exchange program.

The company blamed the problem with the chargers on a supplier, BYD Co. -- run by Wang Chuanfu, who Forbes says is the wealthiest man in China. All the chargers being recalled were made this year.

Nokia said the chargers subject to the recall are: AC-3E and AC-3U models, manufactured between June and Aug. 9, 2009; and the AC-4U model, manufactured between April 13 and Oct. 25.

Nokia's recall site shows customers how to identify their charger model and determine whether it needs to be replaced. If the charger is subject to the recall, Nokia urges consumers to stop using it until the new charger arrives.
