FIELD: electricity.
SUBSTANCE: power supply device is an adapter including an input circuit (21) for receiving input electrical power, a power switch device (25), a power inductance coil (24) and an output circuit (22) connected to the power inductance coil for providing power supply to the portable device, and a controller (26) for the power switch unit control according to the power supply demand for the portable device. The adapter has a measuring inductance coil (27) magnetically connected to the power inductance coil, and the controller includes a measurement input (28) for detecting the measurement signal indicating the power inductance coil magnetic state. The controller detects the power supply demand based on the magnetic state in response to the said power switch device control. Portable devices can be successfully provided with suitable power supply.
EFFECT: providing power supply for various portable devices.
