Caravan & RV Fridges: Compressor vs 3-Way

Caravan & RV Fridges: Compressor vs 3-Way

by Caravan & Camping Aus

Choosing the right fridge for your caravan or RV can make a big difference on the road. Whether you’re heading off for a weekend getaway or doing the big lap around Australia, keeping your food and drinks cold is a must.

In this guide, we break down the two most common options, compressor fridges and 3-way fridges, to help you figure out what’s best for your setup.


 

What Is a Caravan or RV Fridge?

A caravan or RV fridge is specially designed to handle mobile travel. Unlike your fridge at home, these fridges are built to run off multiple power sources and survive bumpy roads and off-grid conditions. The two main types are:

  • Compressor Fridges (2-way)

  • 3-Way Fridges

Compressor Fridges: Reliable Cooling Power

How They Work

Compressor fridges (also called 2-way fridges) work just like your home fridge. They use a small compressor motor to cool the interior, and they can run on either 12V battery or 240V mains power.

Pros

  • Work on uneven ground and off-road.

  • Cool efficiently, even in hot weather.

  • Can freeze food and drinks.

  • Great for off-grid travel when paired with solar or generator.

Cons

  • Can make a bit of noise.

  • Need extra gear like batteries and solar panels.

  • Batteries need to be recharged regularly.

 


3-Way (Absorption) Fridges: Flexible Power Options

How They Work

3-way fridges can run on 12V battery, 240V mains power, or LPG gas. Instead of a compressor, they use a gas flow exchange system to cool things down.

Pros

  • Run silently.

  • Can operate for weeks on a single gas bottle.

  • Great for long stays in one place.

  • No need for charging setups like solar or generators.

Cons

  • Need to stay level to work properly.

  • Not great for rough terrain or driving while in use.

  • Don’t cool as strongly—may struggle in hot weather.

  • Not ideal for freezing food or keeping perishables for long.

Which Fridge Is Best for You?

The best caravan or RV fridge depends on how you travel.

Choose a Compressor Fridge if:

  • You want strong, consistent cooling (even freezing).

  • You travel off-road or camp off-grid.

  • You're okay investing in a battery and charging system.

Choose a 3-Way Fridge if:

  • You camp in one place for a while.

  • You prefer using gas over electric.

  • You don’t need freezing or heavy-duty cooling.

  • You mostly stick to level campgrounds and smooth roads.

Maintenance Tips for Caravan Fridges

No matter what type of fridge you choose, regular maintenance is key. Have your fridge checked along with your caravan before long trips. For best results, trust experts like Caravan & Camping Aus for advice, servicing, and spare parts.

FAQs About Caravan & RV Fridges

What’s the difference between a compressor fridge and a 3-way fridge?

Compressor fridges use a motor and run on battery or mains power. 3-way fridges use gas flow and can run on gas, battery, or mains - but they need to stay level and don’t cool as powerfully.

Can I run a 3-way fridge while driving?

Technically yes, using 12V battery, but it's not very efficient. Most people switch to gas or mains once they stop.

Are compressor fridges better for off-grid travel?

Yes. With solar or battery setups, compressor fridges are more reliable off-grid and don’t need to stay level.

How long does a gas bottle last on a 3-way fridge?

A standard 9-litre LPG bottle can run a 3-way fridge for 2–3 weeks, depending on the conditions and fridge size.

Do 3-way fridges work in hot weather?

They can struggle. 3-way fridges rely on ambient temperature, so they might not keep things cold enough during summer heat.

Final Thoughts

Choosing the right caravan or RV fridge is all about your travel style. If you’re always on the move and want strong cooling, go for a compressor fridge. If you’re camping in one spot for a while and want a quiet, no-fuss option, a 3-way fridge might suit you better.
