The Ultimate Guide to Maximizing Your Camper Trailer's 12V System with Anderson Plugs

Tips and Tricks for Effective Power Management

How to get the most out of your Anderson Plugs.

As more and more adventurers hit the open road with their 4WDs and camper trailers, the importance of a well-equipped electrical system cannot be overstated. From powering essential lighting and fridges to charging phones and cameras, the demands on a rig’s 12V system are greater than ever.

That’s where Anderson plugs come in. Nowadays, they’re the go-to for many camper trailers’ 12V systems. But is simply having an Anderson plug enough to keep your system running smoothly while driving? Not quite.

If you’re looking to make the most out of your 12V system, keep reading for our top tips on getting the most out of your Anderson plug and wiring.

Anderson Plug
  1. The Right Batteries: Before diving into Anderson plugs and wiring, it’s important to ensure you have the right battery setup. For camper trailers, deep cycle batteries are the way to go. These batteries are specifically designed to discharge to around 80%, allowing you to use the power you need for longer periods of time. Make sure to choose a battery rated in ampere hours (Ah) so you can calculate the amount of discharge time you have.

  2. Harnessing the Power of the Sun: Depending solely on your vehicle’s alternator to recharge your camper trailer’s battery via the Anderson plug can be challenging. But adding quality solar panels can help replenish your power usage when your rig is stationary. There are four types of solar panels available, including mobile fold-out panels or solar blankets and fixed panels for your trailer or vehicle. Connect your portable solar panels to your camper trailer’s Anderson plug to introduce them to your power mix. Just be sure to fit a regulator between the battery bank and the panels to avoid damaging the battery with overcharging.

  3. DC-DC Chargers: To take your 12V electrical system’s capabilities to the next level, install a DC-DC charger between the Anderson plug and your battery in your camper trailer. You should also consider installing a DC-DC charger under your fourbie’s bonnet if you have a second in-car battery installed. DC-DC chargers allow you to achieve close to 100% charging capacity to your auxiliary batteries, ensuring you have ample power when you need it most.

  4. Wiring Matters: When it comes to 12V wiring, bigger is better. While a 50A Anderson plug can handle a fair amount of power, if your electrical wire is too thin, the voltage will drop too low to charge the battery effectively. The wiring to the rear of your vehicle should be at least 6mm and no longer than 5-6 metres to minimize this voltage drop.

With good quality Anderson plugs, you can maintain connections over even the roughest terrain. They’re also great replacements for common 12V cigarette lighter outlets that tend to “pop-out” over bumpy tracks, especially for high draw essentials like your fridge.
