车上点烟器没人用？车企为啥还不取消它

Core Viewpoint - The article discusses the multifunctionality of the car cigarette lighter socket, highlighting its evolution from a smoking accessory to a versatile power source for various electronic devices in vehicles [1][5][18]. Group 1: Original Functionality - The car cigarette lighter socket was originally designed for lighting cigarettes, providing a 12V DC power source for car electronics [3][5]. - It has been a standard feature in vehicles to mitigate safety risks associated with using lighters in cars, especially in hot weather [5][7]. Group 2: Current Uses - Despite the decline in smoking, the cigarette lighter socket remains essential for powering devices like dash cams and car refrigerators, which require 12V DC [7][9]. - It can also be used with an inverter to convert 12V or 24V DC to 220V AC, allowing the use of standard household appliances in vehicles [9][11]. Group 3: Safety and Usage Guidelines - Users are advised to choose chargers with overload protection to prevent damage to the vehicle's electrical system [12]. - It is recommended to use dust caps when the socket is not in use to prevent debris from entering [13]. - Avoid connecting high-power devices when the vehicle is parked for extended periods to prevent battery drain [14][15]. Group 4: Industry Perspective - The transition from traditional cigarette lighter sockets to USB ports is not straightforward due to the need for redesigning vehicle electrical systems, which can be costly [17]. - Some manufacturers have adapted the cigarette lighter socket into a "car power socket" with enhanced safety features, indicating a trend towards maintaining this interface in modern vehicles [17][18].
