What is the size of a car cigarette lighter?
2 Answers
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.
