What Are the Reasons for a Car Cigarette Lighter Socket Not Having Power?

[LaReid]

The reason why a car cigarette lighter does not have power is due to prolonged use, where repeated insertion and removal can cause the spring clip to loosen, preventing the lighter from receiving power. Another reason is that repeated plugging and unplugging, along with improper use, can lead to a short circuit in the wiring, burning out the fuse. First, try connecting a car cigarette lighter of the same model. If everything works normally, then the issue lies with the rectifier itself, and it should be replaced immediately. If it still does not work, then the fuse for the car cigarette lighter is likely the problem. You can replace it yourself by locating the fuse box for the vehicle's electrical equipment. The location of the fuse box varies depending on the car brand and model—some are in the storage compartment, while others are under the dashboard. Open the cover of the fuse box and refer to the fuse location diagram pasted on the inside of the cover to find the fuse for the car cigarette lighter. Use the included fuse puller to remove the blown fuse and replace it with a new or spare car cigarette lighter fuse. Precautions for using the cigarette lighter: Avoid using electrical devices with excessively high power on the cigarette lighter. The maximum power a cigarette lighter can generally handle is 120W. Exceeding this value can overload the lighter, leading to various hazards such as burning out the lighter. If using the cigarette lighter for an extended period, try to start the vehicle. If you need to use the cigarette lighter for a long time or if the device has high power, start the car engine to enhance the power supply, preventing excessive drain on the car battery. Plug and unplug the cigarette lighter properly. The cigarette lighter has a separate fuse mechanism. The correct method is to insert and remove it vertically—do not wiggle it while pulling it out. Frequent wiggling can loosen the fuse or cause a short circuit, which may burn out the fuse or external devices.
