The aperture of a car cigarette lighter is 2.6cm, with a power supply voltage of 12 volts. Here is an introduction to car cigarette lighters: 1. Introduction: The cigarette lighter is a device in a car. In the traditional sense, a cigarette lighter draws power from the car's power supply to heat an electric heating unit such as a metal heating plate or wire, providing a flame source for lighting cigarettes. 2. Function: Besides lighting cigarettes, a 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 with ordinary electrical appliances.

The standard size of a car cigarette lighter is generally around 12mm in diameter, a dimension that has been carried over from the early days of cigarette lighters to ensure a secure plug insertion. I often use it in my car to charge my phone or GPS, and I've found that uniform sizing is crucial to avoid poor contact caused by incompatible adapters. Most new and old cars maintain this specification today because international standards ensure high compatibility. When purchasing car appliances like air purifiers or heated cups, simply mentioning a cigarette lighter interface ensures usability. A size too large can lead to looseness and overheating, while one too small won't fit, so avoid modifying the socket arbitrarily. The depth is about 20mm, which together guarantees a safe connection.

The cigarette lighter measures approximately 12mm in diameter, which was also common in older vehicles. I recall that cigarette lighter plugs used to be this size, and now they've become power sockets, making it much easier for me to power my devices. The consistent size prevents confusion—just choose a 12mm adapter when purchasing. In practical use, the size is crucial for charging safety: too large may blow a fuse, while too small won't supply power. During maintenance, check the socket to ensure no foreign objects block the hole; the standardized size reduces risks. Keep it as is and avoid unnecessary adjustments.

The cigarette lighter socket is approximately 12mm in diameter, perfectly fitting charging adapters. It's commonly used to recharge phones during road trips, and its standardized size simplifies accessory selection: mentioning 'cigarette lighter' immediately indicates the size specification. Using sockets that are too small or large can be unsafe, potentially causing short circuits.
