1. A method for transmitting power wirelessly, comprising:
checking a position of a receiving device while wirelessly transmitting power to the receiving device;
adjusting a charging stop level downwardly which is compared with power loss which corresponds to a difference between transmitted power transmitted to the receiving device and received power received by the receiving device, when it is checked that the receiving device is outside a charging area based on that the received power is equal to or greater than a reference power and a power control level when transmitting the power to the receiving device is equal to or greater than a reference value;
stopping the transmitting of the power when the power loss is higher than the charging stop level; and
returning the adjusted charging stop level to an original value when the power loss is lower than the adjusted charging stop level until a predetermined time elapses after adjusting the charging stop level.
