A Simple Guide to 12V Electrical plugs for Your Vehicle

If you've got a vehicle loaded up for camping, off-roading, or just a road trip, understanding how 12 Volt plugs work and the different kinds of electrical sockets you can use is key. You don’t want to get stuck without power for your fridge, lights, or phone chargers, right?

Here's a straightforward rundown to help you make sense of your 12V auto electrical system.

Types of 12V Electrical Sockets in Vehicles

Accessory Sockets (Cigarette Lighter Socket)

Remember when cigarette lighters were in every car? Well, that spot is now your go-to 12V socket. It’s great for phone chargers, small fans, and dash cams. Most vehicles have these near the dash or console, and they’re the easiest to use for basic, smaller current accessories.

Anderson Plugs

When you're going off-road or camping, Anderson plugs are a big step up. These heavy-duty connectors are used for things like camping fridges, solar panels, or dual-battery setups. They handle higher currents than your typical 12V cigarette socket, making them ideal for more power-hungry equipment. They’re Often wired to a deep cycle batteries to provide a higher amperage outlet, or to service as an input from the vehicle to provide charge to the battery. Plus, they’re built tough, and hold up better when mounted externally.

A wide range of colour coded variants are also available. These are keyed differently, allowing drivers to colour coordinate their accessories without risk of incorrectly connecting accessories!

Merit Plugs

Smaller but more secure than cigarette sockets, Merit plugs are designed to keep things steady—no losing power just because you hit a bump! These are a good option if you’re powering sensitive gear like fridges or lighting that needs a stable connection while driving on rough terrain.

USB Sockets

These are the modern-day heroes for charging your phone, tablet, or camera while you’re on the go. A lot of newer vehicles have these installed already, but if not, you can easily add a few USB ports so everyone in the car can charge up at the same time.

Engel Plugs

If you’re running an Engel fridge—known for their reliability—this plug is a must. Engel plugs are designed specifically for these fridges, so you won’t have to worry about them disconnecting. These sockets offer a super snug and secure connection, which makes them perfect for long road trips or rugged off-road journeys.

What Can You Power with Your 12V Plugs?

Whether it’s a fridge, lights, or even a small inverter, your 12V sockets will become your best friend on any adventure. Here's a breakdown of common devices and their power needs to give you an idea of what each plug can handle:

• Camping Fridges: 50-150W

• Phone Chargers: 10-20W

• LED Camp Lights: 10-50W

• Small Inverter (to run AC devices): 150-300W

While cigarette lighter sockets handle up to about 120W (approx. 10 amps at 12 volts), heavy-duty connectors like Anderson are built to handle about 600W - approx. 50 amps at 12 volts!!

Sizing Your Electrical Needs

Before setting off on your next trip, it’s worth checking what gear you plan to power and how much energy each item draws. Make sure your plug setup can handle the load! For example, while your cigarette lighter socket can charge your phone, it’s probably not the best option for your large camping fridge or an inverter. Anderson plugs or Merit plugs are better suited for these bigger power needs.
