Can the car charger be left plugged in all the time?

[VonLukas]

The car charger can remain plugged into the vehicle without causing any harm to the circuit. However, for the sake of vehicle maintenance, it is recommended to unplug it when not in use. Here are some relevant details: 1. When parking and turning off the engine: Some vehicles automatically switch their circuits to an inactive state when parked and turned off. However, in other vehicles, the power to the car charger may not be cut off after the engine is turned off. Although the voltage and current are minimal, prolonged operation can directly affect the battery's storage capacity. 2. After charging is complete: If the car charger remains plugged into the charging port after charging is finished and is not in use, it continues to draw power, which can accelerate the aging of the charger itself and may also pose potential circuit safety hazards.
