12. A power transmission device comprising:
-
a power transmitter configured to wirelessly transmit power to power reception device; and a power transmission decider configured to decide based on a detection signal, which is received from the power reception device, whether the power reception device exists in a power transmittable area in which an average consumption power of the power reception device is able to be transmitted, and that, when deciding that the power reception device exists in the power transmittable area, causes the power transmitter to perform power transmission. - View Dependent Claims (13, 14, 15)
