The 12V 120W power supply in a car can be used to connect external electrical devices such as car phones, portable DVD players, and mobile phone chargers. 12V Power Supply: The 12V power supply in a car is an interface that provides power to external electrical devices. Its output voltage is 12V, and the current varies depending on the vehicle model. The maximum power that a 12V car power supply can handle is 12W. Common Car Power Sources: The most commonly used power source in a car is its built-in battery. The standard voltage for car power supplies is generally 12V DC. When the car is running, the engine drives the alternator, which can generate electricity to charge the battery and power other electronic components in the vehicle.
As a young person who often drives to go camping, the 12V 120W power outlet in the car is super practical. It can power small fans, car refrigerators, or charge phones and tablets, ensuring no power shortage troubles during long trips. 120W means a maximum current of 10A, which is enough for daily devices but don't plug in high-power appliances like microwaves, otherwise the fuse will blow and you'll have to repair the car. I use it to connect small lights for a great atmosphere during picnics. The power outlet connects via the cigarette lighter socket, which is convenient and safe. Just remember to check the device's power to avoid overload, as the car battery has limits. For long-term use, it's best to keep the engine running to maintain power.
