ABSTRACT:
An adapter unit for adaptively supplying a portable radio unit with electric power is disclosed. When the portable radio unit being not powered by a rechargeable battery attached thereto or being not in a communication state is connected to the adapter unit, the first power supply circuit of the adapter unit supplies the rechargeable battery or the portable radio unit with power. When the portable radio unit being in the communication state is connected to the adapter unit, the second power supply circuit of the adapter unit supplies the portable radio unit through the rechargeable battery with power. Power supply capacity of the second power supply circuit is larger than that of the first power supply circuit.
