The invention discloses a power supply device and a power supply method. The power supply device comprises the components of M receiving ends which are used for receiving M input currents from M power supply interfaces, wherein M is an integer which is larger than or equal with 2; a control circuit which is connected with the M receiving ends and is used for processing the M input voltages that correspond with the M input currents for outputting a power supply current that accords with a preset condition, wherein the current value of the power supply current is larger than a random input current value in M input current values which correspond with the M input currents; and an output end which is connected with the control circuit and is used for outputting the power supply current to electronic equipment that is connected with the output end, thereby charging an electric energy storage unit in the electronic equipment. The power supply device and the power supply method provided by the invention are used for
