What Causes the Cigarette Lighter to Lose Power?
3 Answers
The cigarette lighter loses power due to: 1. Damage to the cigarette lighter; 2. A blown fuse for the cigarette lighter. If the cigarette lighter is damaged, replace it directly. If the fuse is blown, you can replace it yourself. The steps to replace the fuse are: 1. Locate the fuse box for the car's electrical components, which may be inside the storage compartment or under the dashboard; 2. Open the fuse box and refer to the fuse layout diagram on the inside of the cover to find the position of the cigarette lighter fuse; 3. Use the provided fuse puller to remove the blown fuse and replace it with a new or spare cigarette lighter fuse. The cigarette lighter is a standard component in all vehicles, designed to provide a convenient ignition source for smokers.
Last time I was driving, I found the cigarette lighter had no power, which was so frustrating! The most common reason is a blown fuse, possibly due to using a power bank or cigarette lighter device with too high a wattage. There's a fuse box in the car, usually located under the dashboard or in the engine compartment. Check the manual to find the corresponding fuse for the cigarette lighter and try replacing it with a new one. Another possibility could be a short circuit in the wiring or poor contact in the socket, such as oxidation caused by humidity during the rainy season. Gently wiggle the plug to see if it restores the connection. If you're not sure what to do, quickly find a repair shop to check it out—don't force it to avoid damaging other circuits. Also, a quick reminder: avoid using low-quality chargers to prevent such issues.
A cigarette lighter socket losing power is usually caused by minor issues. A blown fuse is the prime suspect—it automatically cuts off when overloaded to protect devices, like from rapid charging or internal short circuits. Next, check for loose or aged wiring connections by gently plugging and unplugging the lighter or testing with another device. The socket itself may wear out and lose contact, so regular cleaning helps. While driving, avoid charging high-power devices, especially phones or car fridges, which are prone to issues. Remember, safety first—stay calm, troubleshoot, then fix.
