Charging systems ( 10, 70 ) are disclosed that generally employ forces generated by at least one magnet ( 16 - 22 ) or ( 76 - 82 ) to guide and urge a rechargeable, portable or mobile electronic device ( 12, 72 ) toward a charging position with respect to a charging base ( 14, 74 ) therefor. By using magnetic forces to guide or urge the device ( 12, 72 ) to the charging position, substantially frictionless charging systems ( 10, 70 ) can be provided herein for shifting the device ( 12, 72 ) to its charging position. Either repulsion or attraction forces can be employed. Accordingly, depending on which magnetic force is used to urge the device ( 12, 72 ) to its charging position, an opposite magnetic force is preferably provided to provide the user a tactile indication of improper alignment of the device ( 12, 72 ) and charging base ( 14, 74 ). Preferably, pairs of opposite single pole magnets are used so that there is one pair ( 16, 18 ) or ( 76, 78 ) associated with the device ( 12, 72 ) and another pair ( 20, 22 ) or ( 80, 82 ) associated with the base ( 14, 74 ).
