How to Plug a Generator Into a Caravan?
Let’s face it—nothing ruins a peaceful outback getaway faster than a flat battery or a fried fridge. If you’re travelling with a generator and not sure how to hook it up safely to your caravan, don’t stress. The short answer: use a proper 15A lead and an adapter like the Ampfibian RV Plus—and keep reading for the full how-to.
How to Plug a Generator into a Caravan Using an Adapter
If you've ever tried to force a 10A plug into a 15A caravan socket and thought "that’ll do," pump the brakes. Caravan power systems are designed for higher loads and need a proper connection. That's where generator adapters come in.
Using the right one isn’t just about convenience — it's about safety, legal compliance, and not blowing your fuse mid-barbeque.
Understanding the 4 Prong Generator to RV Adapter
Some generators come with 4-prong twist-lock outlets, especially units designed for the US or industrial markets. These aren’t plug-and-play with most Aussie vans.
You’ll need a 4-prong adapter that converts the twist-lock connection into a usable 15A output. Make sure the voltage and amperage match your setup — otherwise, it’s a no-go.
The Versatility of a Generator Plug Adapter
Not all generators are created equal, and neither are the plugs. A plug adapter like the Ampfibian RV Plus bridges the gap between a 10A outlet and your 15A caravan inlet.
It’s not just a converter — it’s a safeguard. It stops power from backfeeding into the grid and protects against overload. If your setup includes solar or shore power too, this little unit becomes the unsung hero.
Connecting with a 3 Prong Generator to RV Adapter
Got a generator with a 3-prong outlet, like what you’d use on a power saw? You’re not out of luck — you just need the right adapter.
Look for one that safely converts to a 15A caravan socket, and make sure it’s weatherproof and RCD-protected. Filing down the earth pin to "make it fit" is a fast track to danger and insurance drama.
Powering Your Caravan without the Main Generator Inlet
Not every caravan comes with a dedicated generator inlet. But with the right kit and a bit of know-how, you can still run everything from a toaster to a full air con setup off your generator.
The Importance of Inverter Generators
For most travellers, inverter generators are the go-to. They’re quiet, efficient, and deliver clean power without the spikes that can fry your gear.
Models like the Honda EU22i and Stanley ST3200i are popular choices because they’re reliable, compact, and portable. You can throw one in the back of the ute and fire it up wherever the road ends.
They're ideal for short-term power or topping up the van's batteries when the sun ducks behind the clouds.
Essential Safety Measures for Using a Generator
Let’s keep this simple — safety first, always. Here’s your non-negotiable checklist:
-
Never run a generator inside your van, tent, or under your awning. Carbon monoxide is invisible and deadly.
-
Keep it at least 3 metres away from living areas, with the exhaust facing away.
-
Store petrol in approved containers, well away from heat and sparks.
-
Lock it up. Generators go missing from campsites all the time.
-
Use an RCD or a generator with built-in safety features like overload protection.
A few extras to keep in the van: spare 15A fuses, a multimeter, and a bit of common sense. That way, you're ready for whatever the bush throws at you.
