PROBLEM TO BE SOLVED: To simplify or eliminate a transfer constitution, such as a converter and an inverter provided at load devices in a power feed system for feeding power from a power feed adapter to a plurality of load devices. SOLUTION: An electric shaver 32 shown in Fig. 1(a) and a cleaning apparatus 33 shown in Fig. 1(b) can be connected to the power feed adapter 1. The tip of a razor in the electric shaver 32 shown in the Fig. 1(b) can be cleaned, and the electric shaver 32 can be charged as electric shaver 32 is mounted to the cleaning apparatus 33. The power feed adapter 31 outputs AC power of 30 V at 50 kHz to an output terminal as a power transmitting coil 37, in a single power feed plug 36 for constituting a primary coil in a transformer. Input terminals as power-receiving coils 38, 39 in the electric shaver 32 and the cleaning apparatus 33 for constituting secondary coils in the transformer at tight contact with respect to the power transmitting coil 37 on mutually reverse faces.
