Abstract: The present disclosure relates to a hot-plug protection method and a power supply device. The method includes, when the connection status between the power supply device and the to-be-charged device is detected as disconnected through the detection pin, turning off a switch assembly within a first time period, where the switch assembly is connected in series between the voltage converter of the power supply device and the connection port, and maintaining an output voltage of the voltage converter at a first level within a second time period, the first time period being shorter than the second time period.
