Nokia have recently updated their charging connection and all new Nokia phones features the smaller pin style. Normally this would make your old car and mains chargers redundant, the CA-44 charging adaptor will convert the old connection to fit the new style. You can use the LCH-12, ACP-7X, ACP-8X, ACP-9X and ACP-12X combined with the CA-44 charging adapter to charge your new Nokia mobile phone.
