Choosing the Best Caravan Fridge for Australia: A Complete Guide
Choosing the right caravan fridge can make a huge difference to your travel experience. Whether you're heading off for a weekend escape or planning long off-grid adventures, a reliable fridge keeps food fresh, drinks cold, and your trip running smoothly.
With so many options—from compact 12V models to full-size fridge freezers—it’s easy to feel overwhelmed. This guide will walk you through everything you need to know to pick the best unit for your caravan setup.
Types of Caravan Fridge
Choosing the right caravan fridge starts with understanding the main types of refrigeration systems available. These systems differ in how they cool, how much power they use, and where they perform best. The two primary categories you’ll encounter are compressor fridges and absorption (3-way) fridges—each with its own strengths and ideal use cases.
Compressor Fridges (2-Way)
A compressor fridge operates in much the same way as a household fridge, using a motor-driven compressor to circulate refrigerant gas and remove heat from inside the unit. In caravans, these are often referred to as “2-way” fridges because they run on both 12V/24V battery power and 240V mains when available.
How They Work:
A compressor compresses the refrigerant gas, which becomes hot. As it cools through coils on the outside of the fridge, it becomes a liquid and flows through an internal coil system where it evaporates and absorbs heat, keeping your food cold.
Why They’re Popular:
Efficient cooling — quick temperature drop and stable performance.
Great in hot climates — less sensitive to ambient heat than absorption models.
Level-independent — works well even when your caravan isn’t perfectly flat.
Wide size range — from compact upright models to larger fridge freezer combos.
Considerations:
Slight humming noise from the compressor.
Needs a solid battery and electrical setup to run off-grid.
Compressor fridges are ideal for travellers with strong solar and battery systems, frequent long trips, or those heading into warm, remote regions where efficient cooling matters most.
Absorption Fridges (3-Way)
Absorption fridges, often called 3-way fridges, use heat—not a compressor—to drive the refrigeration cycle. This heat can come from 12V or 240V electrical elements or from burning LPG gas, which provides flexible power options.
How They Work:
A heated solution of ammonia and water creates vapour, which is then condensed and evaporated inside the system to draw heat out of the fridge. This process continues as long as a heat source—gas or electricity—is available.
Benefits of Absorption Models:
Various power sources: run on 12V, 240V or LPG gas.
Silent operation: no mechanical compressor noise.
Great for long stays off-grid where gas is available.
Limitations:
Less efficient in high temperatures: performance can drop in extremely warm conditions.
Must be level: needs to be close to perfectly flat to work properly.
Generally slower to cool than compressor models.
Absorption fridge freezers are often favoured by travellers who spend a lot of time at free campsites without reliable power hookups and already use LPG for other appliances.
Caravan Fridge Power Options Explained
Understanding power options is essential when choosing the right caravan fridge freezer, as your fridge’s performance, efficiency, and suitability for off-grid travel all depend on how it’s powered. Most caravan fridges are designed to run on one or more of the following energy sources: 12V battery power, 240V mains electricity, and LPG gas. Each option suits different travel styles and camping environments.
12V Power: Ideal for Off-Grid Travel
A 12V caravan fridge is most commonly a compressor-style fridge designed to run directly from your caravan’s battery system. This setup is popular with travellers who spend time off-grid and rely on solar charging while stationary or alternator charging while driving.
Because compressor fridges are energy-efficient and maintain consistent temperatures, they pair well with a modern battery setup or a portable power station, which can supply stable power without relying on gas or campsite hookups. This makes 12V systems particularly attractive for remote travel, warm climates, and longer stays away from powered sites.
That said, 12V fridges do require careful energy planning. Battery capacity, daily power consumption, and recharging methods all need to be considered to avoid running out of power during extended trips.
240V Mains Power: Best for Caravan Parks
240V power is typically available at caravan parks and powered campsites. Both compressor and absorption caravan refrigerator models can operate efficiently on mains electricity, making this option simple and reliable when hookups are available.
When connected to 240V, power consumption is rarely a concern, and fridges can maintain optimal cooling performance without placing strain on batteries. For travellers who spend most nights at powered sites, this can significantly reduce the need for complex energy systems.
However, reliance on 240V alone limits flexibility, as it’s not available when free camping or travelling remotely.
LPG Gas: Flexible and Silent Off-Grid Cooling
Gas-powered operation is unique to absorption (3-way) caravan fridges and freezers. Running on LPG allows the fridge to operate without drawing heavily on battery reserves, making it a dependable option for long off-grid stays where electrical power is limited.
Gas operation is also completely silent, which many campers appreciate at night. The trade-off is that gas fridges are less efficient in high temperatures and must be kept perfectly level to work properly. You’ll also need to ensure a steady supply of LPG and comply with installation and ventilation requirements.
Caravan Fridge Size, Capacity & Installation Tips
Choosing the right caravan fridge freezer isn’t just about cooling performance—it also needs to fit your available space and suit how you travel. Size, capacity, and installation requirements should always be considered together to avoid costly mistakes or compromises later on.
Choosing the Right Capacity for Your Needs
When choosing the best portable fridge freezer in Australia, fridge capacity is usually measured in litres, and the right size depends on how many people you’re travelling with and how long you’ll be on the road.
As a general guide:
1–2 people: 35–60L is often sufficient for short trips
2–4 people: 90–130L suits weekend trips and moderate off-grid travel
Families or long-term touring: 150L+ caravan fridge freezers with separate freezer compartments offer greater flexibility
If you only need to keep drinks, snacks, or small amounts of frozen items chilled during short trips, the EcoFlow GLACIER Classic Portable Fridge Freezer's portable design and efficient cooling make it ideal for travellers, couples, or small families, while its robust insulation and level-independent operation ensure reliable performance in off-grid conditions.
Measuring Your Fridge Space Correctly
Before choosing any caravan fridge, accurately measuring the available installation space is critical. Measure the height, width, and depth of the fridge cavity, and double-check all dimensions before purchasing.
Key measurement tips:
Allow space for ventilation and airflow, especially behind and above the fridge
Consider door swing clearance and internal layout
Check whether your caravan is designed for an upright, drawer-style, or built-in fridge
A common rule is: measure twice, buy once. Even a small difference in depth or height can rule out certain models.
Installation: DIY or Professional Fitment?
Installation requirements vary depending on the type of caravan refrigerator you choose.
Compressor fridges are generally easier to install and can often be fitted as a DIY project. They run on 12V or 240V power and don’t require external flue systems, but they still need proper ventilation to dissipate heat efficiently.
Absorption (3-way) fridges must be installed by a certified gas fitter. They require compliant gas connections, sealed rear compartments, and correctly positioned vents to safely release heat and gas fumes.
Improper installation can significantly affect cooling performance and safety, so it’s important to follow manufacturer guidelines and local regulations.
Ventilation and Insulation Matter More Than You Think
Regardless of fridge type, good ventilation is essential. Poor airflow can cause higher power consumption, reduced cooling efficiency, and unnecessary strain on components.
High-quality caravan fridges and freezers typically feature better insulation, helping them maintain internal temperatures with less energy. Cheaper models may look appealing upfront but often struggle in hot weather due to inferior insulation and airflow design.
If you regularly travel in warm climates, prioritising insulation quality and ventilation design can make a noticeable difference to performance and energy use.
Upright vs Drawer-Style Fridges
Space constraints can also influence the type of fridge you choose:
Upright caravan fridges are the most common and offer easy access and larger internal capacity.
Drawer-style fridges are ideal for campervans, motorhomes, or tight layouts where vertical space is limited. They often have lower power consumption and improved accessibility.
Choosing the right form factor ensures your fridge fits both physically and practically into your caravan lifestyle.
