1. An accessory apparatus for wirelessly charging an external device, the accessory apparatus comprising:
- a front cover;
a rear cover configured to accommodate a mobile device;
a coupling member configured to link the front cover to the rear cover;
a wireless power control processor;
a connector configured to electrically connect the accessory apparatus to the mobile device;
a direct current-alternating current (DC-AC) converter configured to convert DC power from the connector into AC power; and
a transmission coil configured to wirelessly transmit power through magnetic fields generated by the AC power,wherein the wireless power control processor, the DC-AC converter, and the transmission coil are arranged in the front cover, andwherein the transmission coil is further arranged in the front cover to wirelessly transmit the magnetic fields towards the external device for charging the external device, andwherein the transmission coil is further arranged in the front cover to wirelessly transmit the magnetic fields towards the external device through at least one of an outside of the front cover or an inside of the front cover.
