Compressor vs Absorption Caravan Fridges - Pros and Cons

Intro
Most modern caravan setups favour 12V compressor fridges, but absorption units still have use cases. Here’s how the two compare for Australian touring.

Compressor Fridges (12V or 12/24V)

• Cooling performance - strong in hot weather, fast pull-down.
• Efficiency - low average power with smart thermostats and good insulation.
• Installation - simpler ventilation needs than gas units.
• Power - run from battery, solar, alternator, or DC-DC charger.

Considerations

• Plan battery and solar to suit your travel and climate.
• Use correct cable gauge to minimise voltage drop.

Absorption Fridges (3-way - gas, 12V, 240V)

• Fuel flexibility - can run on LPG when camped without power.
• Quiet running - no compressor cycling noise.

Considerations

• Heat sensitivity - performance drops in hot climates without perfect ventilation.
• Levelling - need to sit close to level for best operation.
• Complex install - certified gas fitting and strict venting requirements.

Which Should You Choose

• Off-grid with solar and lithium - compressor.
• Occasional gas use, cooler climates - absorption can work if well vented and level.

Bottom line
For most Aussie conditions, a quality 12V compressor fridge is the safest bet for reliable cold food and simple installation.
