What Causes the Car Cigarette Lighter to Lose Power?

[VanAlivia]

Car cigarette lighter losing power is typically caused by a blown fuse or loose spring clips. The power supply is generally 12V DC, with the central spring contact being the positive pole and the side clips serving as the negative poles, directly connected to the vehicle's battery with matching current and power ratings. The cigarette lighter is a standard component in all vehicles, designed to provide a flame source for smokers. Some premium vehicles feature an additional lighter in the rear seating area. Common lighter interfaces include USB ports or household power sockets. Typically, the lighter has a dedicated power line with an independent fuse, separate from other circuits. Proper usage requires vertical insertion and removal without wobbling, as frequent wobbly extraction may lead to loosening, short circuits, and damage to both the fuse and external devices.
