MOBILE POWER SUPPLY AND METHOD FOR SUPPLYING POWER TO PERIPHERAL DEVICE

The present disclosure provides a mobile power supply and a method for supplying power to a peripheral device. The mobile power supply comprises a first peripheral connection port and a second peripheral connection port, a first group of connection-port processing circuits and a second group of connection-port processing circuits, a control circuit, and a power supply circuit. A control strategy determining circuit in each group of connection-port processing circuits determines a voltage adjustment strategy according to power supply status information of a corresponding peripheral connection port. The control circuit then causes a voltage adjusting circuit in the connection-port processing circuit to adjust, according to the voltage adjustment strategy, a voltage output by the power supply circuit, such that the adjusted voltage is used to supply power to a peripheral device coupled, by means of a power supply terminal, to the peripheral connection port.
