what is the cigarette lighter in a car called

[DiDante]

The component in your car is officially called a 12V accessory power outlet. While most people still refer to it as a "cigarette lighter," that name specifically describes the removable heating element that was once used to light cigarettes. The socket itself is a DC power outlet that provides 12 volts of direct current from your vehicle's battery.

The original design featured a removable metal coil that would heat up when pushed into the socket. Due to declining smoking rates and the rise of electronic devices, the primary function has shifted. Today, this outlet is almost exclusively used to power or charge devices like phones, GPS units, portable vacuums, and tire inflators via a 12V adapter plug.

It's a simple but vital part of your car's electrical system. The outlet is typically rated for a specific amperage, often around 10-15 amps. Exceeding this limit by plugging in too many high-draw devices can blow a fuse, which is usually located in the vehicle's interior fuse box. The table below shows common devices and their typical power draw.

Device	Typical Power Draw (Watts)	Amperage at 12V (approx.)
Smartphone Charger	10W	0.8A
Portable Air Compressor	120W	10A
Dash Cam	5W	0.4A
12V Cooler	60W	5A
GPS Unit	8W	0.7A

If the outlet stops working, the first thing to check is the fuse. Your owner's manual will identify the correct fuse location. Simply replacing a blown fuse is an inexpensive and easy fix.

Everyone I know just calls it the cigarette lighter, even if we only use it to charge our phones. It's that round plug-in thingy near the gear shift or glove box. My dad still calls it that, and he hasn't smoked in twenty years. The name just stuck. It's way more useful now for keeping my phone alive on a road trip than it ever was for lighting a cigarette.

Technically, the socket is a 12-volt DC power outlet. The term "cigarette lighter" is a legacy name for the heating element accessory that is rarely used today. The outlet's function has evolved into a standard power port for automotive accessories. You'll find its specifications, like maximum current rating, in your vehicle's manual. It's a straightforward piece of engineering designed for low-power DC devices.

Back in the day, it was exactly what it sounds like—a little electric coil you'd push in, it would get red hot, and you'd use it to light your cigarette. Every car had an ashtray right next to it. Now, you hardly see anyone use it for that. It's become the charging port for everything else. It's funny how the name outlasted its original purpose.

I always remind people it’s a power outlet first. The "lighter" part is just a leftover name. The important thing is knowing what it can handle. Don't plug a high-power appliance like a coffee maker into it; you'll blow a fuse. It's perfect for chargers and air pumps. If it stops working, check your fuses before you assume it's broken. It’s a simple system, but you have to respect its limits.
