What is the reason for the sudden loss of power in the car USB port?
1 Answers
Car USB port suddenly loses power because there is a problem with the USB cable or charging module. Its function is to use the standard power supply in the car to charge electrical devices via the USB interface or serve as a fixed power supply interface for electrical devices. It belongs to the vehicle transmission line, with advantages such as fast transmission speed, convenience of use, support for hot-plugging, flexible connection, and independent power supply. It is a universal interface for USB devices like USB drives and MP3 players. How car USB works: It converts the vehicle's 12V or 24V power supply to 5V, and the 5V output is used to charge corresponding electrical devices via the USB interface.
