Abstract
A method and apparatus for wirelessly charging a chargeable device, such as a smart phone, digital music player, or navigation device, using a wireless charger. The wireless charger includes a connector, a retainer, and a wireless power transmitter. The connector is configured to secure the wireless charger to a visor in a passenger compartment of a vehicle. The retainer is configured to selectively retain a chargeable device having a recipient coil. The wireless power transmitter includes a charging coil configured to carry a fluctuating electric current that generates a changing magnetic field for receipt by a recipient coil of the chargeable device. The changing magnetic field induces a fluctuating electric current in the recipient coil, which is used to charge a battery pack of the chargeable device.
