Is the voltage measurement from the cigarette lighter accurate?

[LaLayla]

The voltage measurement from the cigarette lighter is not accurate, as the car cigarette lighter only serves as an auxiliary power source for vehicle testing instruments. Here is some related information about cigarette lighters: 1. Function: In addition to lighting cigarettes, the car cigarette lighter can also be equipped with a car inverter, which converts the 12V, 24V, or 48V DC power in the car into 220V/50Hz AC power for use with ordinary electrical appliances. 2. Precautions: The maximum current that the cigarette lighter circuit can generally withstand is 10A (sometimes 20A). Do not continue to draw power from the cigarette lighter socket when the vehicle is turned off, as this can easily deplete the battery, making it impossible to start the car again.
