The reasons for a car cigarette lighter not working: 1. Due to prolonged use, repeated insertion and removal can cause the spring clip to loosen; 2. Repeated insertion and removal or improper use may lead to a short circuit, burning out the fuse. The power voltage of a car cigarette lighter is 12 volts. When using it, try to insert or remove it vertically. Frequent shaking can easily cause loosening or short circuits, and in severe cases, it may burn out the fuse or even external electronic devices. If you need to use the cigarette lighter for an extended period or with high-power devices, it is advisable to start the car engine to enhance the power supply. This avoids draining the car battery, as the cigarette lighter in the car draws DC power from the car's alternator. As long as the car's engine is running, it can drive the alternator to generate electricity, and all the electrical power used in the car comes from this source.
Last time my car's cigarette lighter suddenly stopped working. At first I thought the lighter head was broken, but then I realized the common causes usually include: a blown fuse (it acts like a protector and cuts off when current is too high); poor contact or rust inside the socket; or short circuits/aged wiring. The cigarette lighter isn't just for lighting cigarettes - it can also charge phones, so losing power affects navigation use. I suggest first checking the fuse box and replacing it with a spare labeled 'cig'. If that doesn't work, the socket might be dirty and need cleaning. Avoid using high-power chargers to prevent overload. Regularly checking these small things can prevent travel troubles. If the problem persists, it's best to have a professional shop check it - safety first.
