Large transport vehicles generally use 24V, while small cars typically use 12V, with current not exceeding 12A. Below is relevant information about car cigarette lighters: 1. Differences: Small vehicle power sources are generally DC 12V (may vary by model), with the central spring contact being positive and the side clips (ears) being negative. It connects directly to the vehicle's , sharing the same current and power specifications. 2. Usage: A car cigarette lighter functions similarly to a household multi-socket power outlet, connecting to the car's power source via a plug to provide multiple lighter sockets. The cigarette lighter socket is particularly useful for owners who frequently use car electronics, such as charging mobile phones or MP3/MP4 players. Additionally, besides serving its primary function, the car cigarette lighter can be equipped with a car power inverter to convert the vehicle's 12V, 24V or 48V DC power into 220V/50Hz AC power for ordinary electrical appliances. It's recommended to use a split-type car inverter, with electrical appliances limited to below 150W to ensure output current doesn't exceed the battery's capacity.
