The invention provides a vehicle-mounted power supply device and a power assembly. In the vehicle-mounted power supply device, an alternating-current port receives alternating-current power supply voltage output by an alternating-current power supply and outputs first alternating-current voltage to an alternating-current load, and a high-voltage direct-current port receives direct-current power supply voltage output by a power battery and outputs direct-current charging voltage to the power battery. The first low-voltage direct-current port outputs a first output voltage to the first direct-current load and the low-voltage battery, and the second low-voltage direct-current port outputs a second output voltage to the second direct-current load. When the second low-voltage direct-current port cannot output the second output voltage, the first low-voltage direct-current port outputs the first output voltage to the second direct-current load, and when the first low-voltage direct-current port cannot output the first output voltage, the second low-voltage direct-current port outputs the second output voltage to the first direct-current load and the low-voltage battery. The power consumption of the vehicle-mounted power supply device is reduced, and the size of the vehicle-mounted power supply device is reduced.
