    Abstract: An electronic device for wirelessly transmitting power may include a first resonator including a first coil, a second resonator including a second coil having a different size from the first coil, an impedance matching circuit including at least one capacitor connected through a switch, and a controller. The controller may be configured to identify which one of a first electronic device not mounted on the electronic device and a second electronic device mounted on the electronic device power is to be transmitted to. The controller may be configured to, when power is to be transmitted to the first electronic device, transmit power through the first resonator by opening the switch. The controller may be configured to, when power is to be transmitted to the second electronic device, transmit power through the second resonator by closing the switch.
