Wireless charger using a way of inductive coupling

PURPOSE: A wireless charger using an inductive coupling method is provided to improve power efficiency by arranging a first coil on a second coil of an internal battery when any kinds of portable devices are loaded on a touch pad. CONSTITUTION: A touch pad(102) is formed on one surface of a housing(101). A first coil is provided to the housing. A driving device horizontally moves the first coil on the plane parallel to the surface with the touch pad. If a portable device is loaded on the touch pad, the touch pad senses the position of a portable device(200) and drives the driving device to move the first coil to face a second coil.
