You’ll most often hear it called a 12V accessory outlet. In older vehicles, it’s also commonly referred to as a cigarette lighter socket. It supplies 12‑volt DC power from your vehicle, which is different from household AC power.

• Other names you may see: 12V DC outlet, car power outlet, auxiliary power socket.
• Typical use: Powering small electronics and car accessories, or feeding a power inverter that provides standard AC outlets and USB ports.
• Good to know: The outlet is usually protected by a fuse and may have limits on how much power it can safely provide. Always check your vehicle’s owner’s manual for location and usage details.

It’s designed for low‑to‑moderate power accessories. Many drivers use it for convenient charging and small gear.

• Common direct‑plug items: Phone chargers, GPS units, dash cams, small air purifiers, portable coolers/warmer boxes, and compact tire inflators designed for 12V sockets.
• With a power inverter: You can convert 12V DC to standard AC to run devices like laptops, camera chargers, or small fans—within the inverter’s and vehicle outlet’s limits.
• Safety tips: Check the device’s power draw and the outlet/inverter ratings. High‑draw appliances (like large heaters or hair dryers) typically exceed what a car outlet can support. To avoid battery drain, unplug accessories when the engine is off unless your vehicle/manual says otherwise.

Start with what you want to power, then match an inverter to those needs.

• Wattage: Add up the continuous watts your devices use and choose an inverter with headroom. Consider peak/surge needs for devices with motors.
• Wave type: Pure sine wave is typically friendlier to sensitive electronics; modified sine wave can work for many basic loads.
• Connection: Plug‑in models suit lighter loads via the 12V outlet; higher‑watt inverters often connect to the battery and may require careful installation.
• Ports & features: Look for the number of AC outlets, USB/USB‑C, low‑voltage shutoff, and overload protection.
• Fit & cooling: Consider size, cord length, noise, and ventilation. When in doubt, check your vehicle manual or consult a professional.

They’re still fairly common, though placement and quantity vary by vehicle and trim. Many newer models include at least one 12V accessory outlet, even as USB and built‑in AC ports become more popular.

• Typical locations: Center console, dashboard, under the armrest, rear seat area, or cargo space.
• What varies: Some vehicles have multiple 12V points; others focus on USB‑A/USB‑C or include a factory AC outlet.
• Tips: Check your owner’s manual or a quick interior scan to confirm locations and power limits. If your vehicle includes a 12V outlet, you can use plug‑in accessories or a compact inverter for AC power within the stated ratings.

It’s a round socket, usually with a flip‑up cap or cover labeled “12V,” “DC,” “Power,” or showing a lighter icon. Inside, you’ll see a center contact and metal side walls that match a standard 12V plug.

• Where to find it: Often on the dash or console; sometimes in the glove box, rear console, or cargo area.
• How it’s used: Insert a 12V plug until it seats firmly; many plugs include a spring‑loaded tip for contact.
• Reminder: This is a DC power port, not a household AC outlet. For AC sockets and extra USB ports, consider a compatible car power inverter used within your vehicle’s limits.
