The car vacuum cleaner cigarette lighter mouth into a usb port into a family car dual-use method:
< br >
The cigarette lighter interface of the car can not be converted into a USB interface, the cigarette lighter interface of the car is 12V voltage, the USB interface is 5V voltage, and there is a data line, which can be converted into a USB interface on the cigarette lighter through the car charger, the specific steps are as follows:

1. Open the door on this side of the cab.

Second, press the brake pedal.

Four, the instrument panel lights up, proving that the engine has started.

5. Insert the car charger into the cigarette lighter port.
No way. Because the car vacuum cleaner is essentially through the vehicle cigarette lighter or directly connected to the vehicle power supply to provide working power, does not consider the charging voltage and current stability of the usb interface, and the working principle of the vacuum cleaner requires large power, generally through the usb interface can not meet the needs.
If you want to use the usb interface to charge the car vacuum cleaner, you need to make chassis changes and corresponding circuit adjustments, need professional and technical personnel to transform, it is best not to change at will, so as not to bring unexpected risks.
1 The car vacuum cleaner can be transformed into a USB interface.
2 Because the car vacuum cleaner is generally powered by the vehicle power supply, and the USB interface also needs a power supply, it can be modified to connect the power cord of the car vacuum cleaner to the USB interface.
3 It should be noted that the transformation process requires a certain amount of electronic technical knowledge and professional tools, if you do not have the relevant skills and experience, it is recommended to seek the help of professionals or buy a special USB interface car vacuum cleaner.
The power supply of the vacuum cleaner must be changed to 220v to 12v DC power adapter, directly changing the plug into 220v will burn the vacuum cleaner, you can buy an adapter, connect the 12v connection line and the power plug of the vacuum cleaner, if not, find a person who will repair the appliance to refit.
