What is the specification of a car cigarette lighter?
2 Answers
Car cigarette lighter aperture specification is 2.6cm. Here is an introduction about car cigarette lighters: 1. Introduction: The cigarette lighter is a device in a car used for lighting cigarettes. In the traditional sense, the cigarette lighter draws power from the car's electrical system to heat a metal heating element or wire, providing a flame source for lighting cigarettes. 2. Function: In addition to lighting cigarettes, the 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 common electrical appliances.
A couple of days ago I tested the cigarette lighter in my car. Most compact cars use 12V DC power, with common rated currents of 10A or 15A. The plug diameter is approximately 21mm, though some American-spec vehicles may be slightly larger. Last time when I used the cigarette lighter to power a car vacuum cleaner, the 180W power draw blew the fuse. Later I checked the manual and found this 15A socket has a maximum capacity of 180W. When installing dash cams, be careful as some poor-quality cigarette lighter adapters may cause poor contact - it's better to choose ones with overload protection. Specifications may vary across models - some older commercial vehicles might use 24V systems, so always check your owner's manual to confirm. Safety first.
