Can the Cigarette Lighter Charger Be Left Plugged In All the Time?

[McPaul]

It can be left plugged into the cigarette lighter without causing any harm to the circuit. The car charger uses a series switching regulated power supply, and when not in use, its circuit automatically stops working. Therefore, it will not affect the circuit's operation. The static current of its circuit is only about 1-2mA, which will not have any impact on the circuit. Additionally, when the car key is turned off, the cigarette lighter will no longer have power. So, feel free to leave it plugged into the cigarette lighter. Below is some relevant information about the cigarette lighter: 1. Function: Besides being used for lighting cigarettes, the car cigarette lighter can also be equipped with a car inverter, which can convert the car's 12V, 24V, or 48V DC power 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 (some can handle 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's power, making it impossible to start the car again.
