Cannot be changed to usb port.
Because the car vacuum cleaner needs to use DC power supply, and the usb interface is powered by AC power supply, the power output of the two is different and cannot be directly converted.
If you do need to convert the power of the car vacuum cleaner to a usb interface, you need to use a converter to convert the direct current to alternating current, and then use the usb interface for power supply.
But this adds cost and complexity, and may not work for all car vacuum cleaner models.
In order to facilitate cleaning in the vehicle, you can choose to buy a car vacuum cleaner with a usb interface, which is more convenient to use.
At the same time, you can also choose to use a car charger or portable charging bank to provide power for the car vacuum cleaner, which is more flexible.
