What is the cigarette lighter connector called?

In modern vehicles, the cigarette lighter connector is no longer just about lighting cigarettes. Instead, it has become one of the most universal 12V power interfaces for cars. However, many drivers and enthusiasts are unsure about its official name and terminology. Is it still called a cigarette lighter? Or does it go by another name? In this article, we will clarify the naming of this connector, explore its functions, and explain why it remains a vital component of automotive power systems.

1. Common Names for the Cigarette Lighter Connector

The cigarette lighter connector has several names, depending on the region, industry, and context. The most common terms include:

  • Cigarette Lighter Plug / Socket – Traditional name from its original function.

  • 12V Power Outlet – Widely used in manuals and modern vehicle documentation.

  • Automotive Accessory Socket – A technical name describing its role as a connector for powering accessories.

  • Car Power Outlet – Simplified consumer-friendly name used by automakers and retailers.

In essence, all these terms describe the same connector — a 12V socket designed for automotive use.

2. Technical Explanation

The cigarette lighter connector is technically a 12V DC socket integrated into a vehicle’s electrical system. It provides direct current (DC) power from the car battery. The connector usually outputs 12V in cars and 24V in larger vehicles like trucks.

This makes it an essential interface for powering devices via adapters such as:

  • EC5 to cigarette lighter adapters

  • Car power supply adapters

  • 12V car charger cables

These adapters convert the raw socket output into suitable power for smartphones, laptops, and other accessories.

3. Uses of the Cigarette Lighter Connector

The modern cigarette lighter socket is mainly used as a universal power outlet. Its applications include:

  1. Device Charging – Phones, tablets, GPS units, and cameras.

  2. Emergency Equipment – Portable jump starters using EC5 to Cigarette Lighter Car Emergency Jump Starter Battery Cable for backup power.

  3. Car Accessories – Air compressors, portable fridges, vacuum cleaners, and dash cams.

The connector’s versatility has ensured its continued existence in nearly every vehicle.

4. Relationship with EC5 and Other Adapters

The cigarette lighter socket works seamlessly with various adapters, making it compatible with portable batteries and jump starters.

This adaptability makes the cigarette lighter connector a crucial part of the automotive power ecosystem.

5. Why the Name Still Matters

Even though “cigarette lighter” is outdated, the term remains popular. People continue to call it that, while manufacturers label it as a 12V accessory power socket in manuals. Both terms are widely understood, so the connector has dual identity:

  • Consumer Name: Cigarette lighter plug

  • Technical Name: 12V DC accessory power socket

Knowing both terms ensures you can communicate effectively, whether shopping for parts or reading a car manual.

Conclusion

So, what is the cigarette lighter connector called? Technically, it is a 12V DC accessory power socket, but most people still refer to it as a cigarette lighter plug. Regardless of the name, its role remains crucial for powering devices and accessories in cars. Whether you’re using an EC5 adapter cable, a car jump starter cable, or a 12V car charger cable, this connector ensures your electronics remain powered on the road.
