An electrical device of the type having a rechargeable battery and which has a body having at least a portion formed with a circumference extending about an axis, is provided with a secondary winding adapted to receive magnetic flux from a planar charging surface that is arranged around the circumference in a plane perpendicular to the axis. Such a device may be charged by placing the device on a planar charging surface such that the body portion contacts the planar charging surface with the axis perpendicular to the charging surface and the secondary winding parallel to the charging surface.
