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

The reasons for a car cigarette lighter not having power are: 1. The fuse is blown; 2. The plug of the cigarette lighter is loose. The method to use a cigarette lighter is: Press the cigarette lighter down to connect the current on the lighter socket and heat the heating wire at the front end of the lighter until it turns red. When the temperature is reached, the lighter will automatically pop out, and the red-hot heating wire at the front end can then be used to light a cigarette. The cigarette lighter is a component found in all cars, providing a convenient fire source for the owner to light cigarettes. In addition to lighting cigarettes, the car cigarette lighter can also be equipped with a car inverter, which converts the car's 12V, 24V, or 48V DC power into 220V 50Hz AC power for use by ordinary electrical appliances.
The cigarette lighter may have no power due to a blown fuse. Last time, after plugging in a phone charger, there was no response. Upon checking the fuse box, I found the cigarette lighter fuse had melted—possibly because the plugged-in device had too high a power, like a laptop charger overloading and causing it to blow. Just replace it with a new fuse, usually located in the fuse box under the steering wheel or in the engine compartment. If it's a poor socket connection, try scraping the contacts inside with a screwdriver or plugging and unplugging multiple times. Short circuits in the wiring are less common but can occur in older cars, in which case a professional should be consulted. In any case, don’t ignore it, as it affects charging convenience while driving. Address it early for peace of mind.
