Cigarette lighter plugs and sockets In cars, they are electrical components used to power electronic devices, such as smartphone chargers, GPS navigators, or other automotive accessories. Although the term "cigarette lighter" originally referred to the ignition function, today the connector is primarily used to power devices via a 12V socket.

Plug (or cigarette lighter adapter)

The plug is a male connector that fits into the cigarette lighter socket. It is cylindrical in shape, generally 21 mm in diameter, and has two electrical terminals that connect the devices to the car's electrical system. Plugs can vary depending on the type of device they need to power (for example, some adapters have multiple USB ports to charge multiple devices).

Cigarette lighter socket

The cigarette lighter socket is a female connector found on many cars, usually located on the center console or near the dashboard. It's designed to accommodate the plug and supply 12V power (typically the standard voltage in cars). While its original function was to power the cigarette lighter mechanism, today it's used to power various devices.

Types of connections

1. Traditional cigarette lighter socket (12V) : Used to light the cigar, but also to power accessories such as chargers, portable refrigerators or camping lights.
2. Cigarette lighter socket with USB port : Some modern models offer built-in USB sockets, useful for charging phones or other devices that require a USB connection.
3. Multiple Plugs : Some adapters allow you to connect multiple devices at the same time, via a cigarette lighter socket, using plugs with multiple USB ports or other types of connectors.

These sockets and plugs are essential for powering electronic devices while traveling, offering convenience and versatility.
