PROBLEM TO BE SOLVED: To confirm whether equipment to be charged is regular, without using any communication means such as light. SOLUTION: When equipment 11 to be charged is placed in a charger 1, charging is started automatically. In the equipment 11, a charge control part 15 turns off a charge off switch 16 by a fixed period according to a signal from a timer 14. When charge is turned off in this manner, temporary increase in the voltage of a transmission coil 4 is repeated with a fixed period. In the charger 1, a confirmation detecting part 5 detects the change in the voltage of the transmission coil caused 4 by the on/off of the charge. A control part 2 determines whether the equipment 11 is regular, according to a signal that is outputted from the confirmation detecting part 5. When it is determined that equipment is not the equipment 11, a power transmission part 3 is controlled, and the charge to the equipment 11 is stopped. |
