POWER SUPPLY DEVICE AND FAN

The invention relates to a power supply device and a fan, which flexibly improves the endurance of the power supply device to the fan through a battery container which can be used for accommodating one or more energy storage batteries. At the same time, in the process of increasing endurance, When the working voltage of each energy storage battery is greater than the first voltage and less than the second voltage, and the working current of each energy storage battery is greater than the first current and less than the second current, the input terminal and the output terminal of the controlled switch module are turned on by the battery protection circuit, otherwise, the input terminal and the output terminal are turned off, that is, the power supply of each energy storage battery to the fan is turned off. Based on this, a power supply device is provided, which effectively improves the endurance and eliminates potential safety hazards caused by the increase in endurance. 本发明涉及种电源装置及风扇，通过可用于容置个或多个储能电池的电池容器，灵活提
