What is the amperage of the cigarette lighter fuse?
2 Answers
The cigarette lighter is generally 10A-15A. Here is more information about the cigarette lighter: Function: The cigarette lighter is a component found in all cars, designed to provide a convenient ignition source for smokers. Heating time: The central elastic head of the cigarette lighter is the positive pole, while the clips on both sides are the negative poles. The car cigarette lighter requires about 10 seconds to heat up and will not automatically pop out until heating is complete. Aging: Frequent insertion or removal of the cigarette lighter can accelerate its aging, so it is advisable to minimize its usage frequency. Acting as a charger: USB-equipped cigarette lighters can also serve as universal car chargers.
When I repair my car, I often encounter issues with the cigarette lighter fuse. The common amperage is around 15A, but it depends on the car model. For example, some Japanese cars might use 10A, while European or American cars sometimes go up to 20A. Last time, mine blew because I connected a car fridge, and the current was too high. The cigarette lighter fuse is located in the fuse box, usually under the steering wheel or in the engine compartment. Just find the corresponding position, check the markings, and test it with a multimeter. If it's blown, the cigarette lighter socket won't have power, so you can't charge your phone or use other devices. I recommend not plugging in too many devices at once, like power banks or GPS, as exceeding the current limit can cause problems. Regularly check the fuse condition to avoid sudden failures during long trips. Replacing the fuse is simple—just swap it with one of the same amperage, but be sure to do it safely.
