What Is a Cigarette Lighter in a Car Called? | Names You Use

You’ve probably used it to charge a phone, run a tire inflator, or power a dash cam. You push a plug in, it wiggles a bit, and the device starts drawing power. Many drivers still call that spot the “cigarette lighter,” even in cars that haven’t shipped with a heating element in years.

The naming gets messy because the part did two jobs over time: it started as an actual lighter, then turned into a general power socket. Automakers, manuals, and parts stores all picked labels that fit their own wording. This article helps you land on the right name, understand what each name points to, and ask for the right thing when you’re buying parts or accessories.

What Is a Cigarette Lighter in a Car Called? Common Names And Labels

In modern manuals and trim descriptions, the most common label is 12-volt accessory power outlet (often shortened to 12V outlet or power outlet). The older everyday label, cigarette lighter, still sticks because the socket shape is familiar and the plug style stayed common.

When you see “accessory” in the name, it’s pointing to the purpose: powering add-ons that aren’t built into the car, like a GPS unit, air pump, mini vacuum, or cooler. When you see “power outlet,” it’s describing the function in plain language. When you see “cigarette lighter,” it’s referencing the original hardware, even if the lighter itself is missing.

Why The Same Part Has So Many Names

Cars didn’t switch over in one clean moment. Some kept the heating element while people started buying phone chargers. Some dropped the heating element and left the socket. Some added extra sockets in the console, cargo area, and rear seat zone, each labeled a little differently.

So the “right” name depends on who’s speaking:

• Owner’s manual: usually “12V power outlet,” “accessory outlet,” or “power point.”
• Parts counter: often “cigarette lighter socket,” “power outlet socket,” or “12V receptacle.”
• Accessory packaging: “car charger,” “12V plug,” or “cigarette lighter plug.”

Two Pieces, Two Names

It helps to separate the terms for the two mating parts:

• Socket / receptacle / outlet: the fixed part mounted in the dash, console, or cargo area.
• Plug: the removable part on your accessory cable that you push into the socket.

If you ask a shop for a “cigarette lighter,” they might hand you the heating element (the spring-loaded push-in piece) or the socket assembly. Saying “socket,” “outlet,” or “receptacle” removes the guesswork.

Cigarette Lighter Socket Names In Manuals And Marketing

Automakers lean on a few recurring labels. You may see one on a fuse box diagram, another printed next to the port, and a third in a spec sheet. The port can still be the same physical thing, just described in different words.

12V Accessory Power Outlet

This is the clearest modern term. It tells you the outlet supplies vehicle battery voltage (nominally 12 volts in most passenger cars) and is meant for accessories. Some cars feed it all the time. Others shut it off with the ignition. Both can still be called “12V outlet,” so the manual matters.

Power Outlet Or Power Point

Some brands use “power point” to make it sound less tied to smoking. It’s still a small DC outlet that takes the familiar cylindrical plug. If you see “power point” on a feature list, treat it as a 12V outlet unless the manual says it’s a different style.

Auxiliary Power Outlet

“Auxiliary” often means “extra” outlets beyond the front dash port, like one inside the armrest or in the trunk. It can also mean an outlet that’s ignition-switched, so it shuts off when the car is off.

Cigar Lighter / Cigarette Lighter Receptacle

You’ll still spot “cigar lighter” in older manuals and in parts catalogs. That wording shows up in technical documents because the part started life as a lighter receptacle. The name stayed in catalogs because it’s searchable and people still ask for it.

How The Lighter Became A Power Outlet

The original setup was simple: a heated element you pushed into a socket until it clicked, then it popped out hot enough to light a cigarette or cigar. The socket had to pass a lot of current for a few seconds, which made it a handy place to draw power.

Once portable electronics took off, accessory makers leaned on the socket as an easy, universal plug-in point. The heating element became optional. Many vehicles stopped including it, but kept the socket so drivers could still power accessories without rewiring anything.

Why The Shape Stuck Around

Even if the connection isn’t perfect, it’s widespread, cheap to make, and already familiar. That’s why you can still buy a “car charger” at a corner store that fits everything from an older sedan to a newer crossover.

These days, many cars also add USB ports. USB is great for phones. The 12V outlet still earns space because it can run gear USB can’t, like an air pump, a portable cooler, or a small inverter for a laptop brick.

Standards That Explain The Naming

One reason the names refuse to die is that the socket form has formal dimensions. In the United States, SAE publishes a standard that covers 12-volt cigarette lighters, power outlets, and accessory plugs. The name itself shows the shift: lighter first, outlet second. You can see the scope on SAE J563, Standard for 12 Volt Cigarette Lighters, Power Outlets, and Accessory Plugs.

There’s also a smaller, tighter connector used on some motorcycles and European vehicles that follows ISO 4165 sizing. It’s often called a DIN socket, BMW accessory socket, or “Powerlet”-style port. A plain overview of where it’s used is on ISO 4165 scope and application.

These standards don’t just set dimensions. They also shape what manufacturers put in documentation and what accessory makers print on packaging.

Cigarette Lighter Socket Vs 12V Accessory Outlet

People often ask if there’s a difference. In daily use, they’re usually the same physical port. The difference is about intent and what’s included from the factory.

When It’s Truly A Cigarette Lighter

If your car has the removable heating element, then the assembly is functioning as a cigarette lighter. The socket is built to handle the current draw for that heater coil.

When It’s A 12V Outlet Only

If the port is just an empty socket with a cap that says “12V,” then it’s a power outlet by design. It may still share the same size as the old lighter receptacle, so older-style plugs still fit.

Why It Matters For Buying Parts

If you’re replacing the part, shops may sell the heater element and the socket separately. If you’re buying an accessory plug, you usually just need to know the socket style: the wide “lighter” style or the narrower ISO 4165/DIN style.

Common Names You’ll Hear And What To Ask For

If you want one phrase that works almost everywhere, use this: 12V accessory power outlet socket. It’s long, but it’s hard to misread.

If you’re speaking with a mechanic or parts store, these short requests usually land well:

• “I need the 12V outlet socket for the center console.”
• “I need the cigarette lighter receptacle, not the heating element.”
• “I need the outlet cap for the 12V port.”

Adding the location (dash, console, rear seat, trunk) is the fastest way to avoid getting the wrong part.

Name You’ll See	Where It Shows Up	What It Usually Means
12V Accessory Power Outlet	Owner’s manuals, trim lists	General power socket for plug-in devices
Power Outlet	Console labels, fuse charts	Same as 12V outlet, sometimes ignition-switched
Power Point	Marketing, feature lists	Brand wording for a 12V outlet
Aux Power Outlet	Rear seat or cargo area	Extra outlet, often for passengers or trunk gear
Cigarette Lighter Socket	Parts catalogs, online listings	The receptacle sized for the classic lighter plug
Cigar Lighter Receptacle	Older service manuals	Same socket, older technical wording
12V Receptacle	Aftermarket wiring kits	Socket assembly meant to be panel-mounted
Accessory Socket	Accessory packaging	Port for a plug-in adapter or charger
DIN / ISO 4165 Socket	Motorcycles, some European vehicles	Smaller port that needs a matching plug

Where You’ll Find It In The Car

Most vehicles have at least one outlet up front. Newer models may scatter them around the cabin to match how people use devices now. The label can change by location, even when the hardware stays the same.

Dash And Center Console

This is the classic spot, close to the driver. It’s handy for phone charging and dash cam power. In some cars, it sits behind a flip-cap so coins and dust don’t drop in.

Rear Seat Zone

Rear outlets are common in family cars and ride-share friendly trims. These ports are often labeled “12V” and may turn off with the ignition so a charger doesn’t drain the battery overnight.

Cargo Area

An outlet in the trunk or cargo bay is meant for tailgate gear, coolers, or air pumps. If you do long drives, this is the port that can carry a lot of the workload.

How Much Power It Can Deliver

Most 12V outlets are fused. A common fuse rating is 10 to 20 amps, which gives a rough ceiling of 120 to 240 watts at 12 volts. Vehicle voltage can run higher with the engine running, so the math shifts, but the fuse rating is still the stop sign.

For phone chargers and small gear, that’s plenty. For high-draw items like big inverters, heated blankets, or plug-in kettles, it’s easy to pop a fuse or heat up a cheap plug. If an accessory lists its draw in amps, multiplying amps by 12 gives a ballpark watt number.

Clues On The Cap Or Near The Port

Some caps list a rating, like “12V/120W.” Others only show “12V.” If you can’t find a label, your owner’s manual or fuse panel legend may show the circuit name and fuse size.

Plug Fit Problems And Why They Happen

If you’ve ever bumped a charger and watched it cut in and out, you’ve seen the weak spot of this connector style. The plug is held in mostly by friction at the side contacts and the tip contact. Vibration and shallow tolerances can break the contact just enough to interrupt power.

These fixes are simple and safe:

• Try a charger with springier side contacts and a longer center tip.
• Clean the socket with the car off and the fuse removed, using a dry swab.
• Check for a loose socket body in the panel; some twist-lock mounts back out over time.

If a plug gets hot at the tip, stop using it. Heat points to poor contact, which can melt plastic and ruin the socket.

How To Tell If You Have The DIN Style Port

A DIN/ISO 4165 style port is smaller in diameter and often sits deeper relative to its opening. It’s common on some motorcycles and a handful of vehicles. The matching plugs tend to lock in tighter than the wide lighter-style plugs, so they wiggle less on rough roads.

If your “car charger” plug won’t fit at all, don’t force it. Check the port size and search for “DIN 4165 plug” or “ISO 4165 plug” accessories. Many riders use adapters that convert between the two styles, but choosing the right plug from the start keeps the connection steadier.

Issue	Likely Cause	What To Do
No power at all	Blown fuse or switched outlet is off	Check fuse chart, test with ignition on, replace fuse with same rating
Power cuts out on bumps	Loose plug fit or worn side contacts	Try a better plug, inspect socket tension, replace socket if worn
Plug tip gets hot	Poor contact at center pin	Stop use, inspect for melting, swap charger, replace socket if damaged
Outlet works only with engine running	Voltage drop at idle or weak battery	Test battery, avoid high-draw gear on a tired electrical system
Accessory won’t turn on	Accessory needs more current than outlet circuit	Check accessory wattage, use a direct-battery connection with proper fuse
Socket feels loose in trim	Retaining ring backed off	Tighten mount from behind panel, replace broken ring
Wrong plug size	DIN/ISO 4165 port vs lighter-style plug	Use the correct DIN plug or a rated adapter

Buying Tips That Save You A Return Trip

Most mix-ups happen because people buy “a cigarette lighter” without pinning down which piece they need. Before you order anything, do three quick checks.

Check Whether You Need The Socket Or The Lighter Element

If your car still has a heating element, it can be replaced on its own. If the port itself is cracked, loose, or melted, you need the socket assembly.

Match The Mounting Style

Some outlets snap into a plastic bracket. Others use a threaded barrel with a retaining ring. A photo from behind the panel is worth more than a guess based on what the front looks like.

Look For A Cap If It’s In The Cargo Area

Cargo outlets see dust, pet hair, and spilled drinks. A tight cap keeps the contacts cleaner and can cut down on flaky charging.

Plain Terms You Can Use In Conversation

If you’re talking to someone who doesn’t care about parts catalogs, keep it simple. Any of these phrases will be understood:

• “12V outlet”
• “car power socket”
• “accessory outlet”

If you’re searching online, adding “socket” or “receptacle” helps you find the fixed port instead of chargers and adapters.

A Quick Checklist Before You Plug In Anything New

• Check the accessory’s wattage and make sure it stays under your outlet’s fuse rating.
• Keep high-draw gear like big inverters on a direct fused battery line, not the dash outlet.
• Use chargers with solid contact springs and a tighter fit, not flimsy plugs.
• If a plug runs hot or the socket smells like warm plastic, stop and inspect the port.

When you know the names, shopping and troubleshooting get a lot calmer. In most cars, that “cigarette lighter” spot is simply the 12-volt accessory power outlet you use every day.
