Buyers Guide: 12V Fridges

Keeping food and drinks fresh is essential for off-grid weekend adventures or long-haul caravan trips. Gone are the days of melting ice packs and waterlogged meals — 12V fridges have long since changed the game.

However, choosing the right caravan fridge isn't as simple as picking the biggest or cheapest option. You need a unit that fits your power setup, keeps contents cool in extreme conditions and lasts for years without trouble.

Whether you're after the best portable fridge for short trips or a caravan fridge that has enough food to last a few days, this fridge buying guide from the experts at Home of 12 Volt breaks down everything you need to know before purchasing. 

Types of 12V fridges

There's no one-size-fits-all solution when it comes to camping fridges. The right type depends on your trip length, budget and power setup. Understanding the different technologies will help you choose a powerful, reliable fridge that meets your needs.

Below is a guide to 12v fridge types:

Fridge type

Pros

Cons

Best for

Thermoelectric fridges

  • Budget-friendly, compact and lightweight.
  • Simple plug-and-play operation.
  • Struggles to cool effectively in extreme heat.
  • High-power consumption

Short day trips or as a backup fridge for snacks and drinks.

Absorption fridges

  • Multi-power operation (12V, 240V or gas) 
  • Silent operation with no moving parts.
  • Less effective in hot weather and uneven terrain.
  • Slower cooling times compared to compressors.

Caravan fridges used at powered campsites or when running on gas.

Compressor fridges (Most popular)

  • Powerful, reliable and efficient cooling in all weather conditions.
  • Low-power draw, perfect for 12V battery setups.
  • Fast cooling and freezing capabilities.
  • More expensive upfront.

Serious campers, off-roaders and long-term travel.

As you can see, a compressor fridge is the most efficient and trustworthy option. It's the preferred choice for long-lasting, off-grid performance without relying on external power sources.

Key features to look for in the best portable fridges

When choosing the best portable fridge, consider your travel style, power setup and durability expectations.

Size and capacity

One of the first things to consider when buying a portable camping fridge is size. A unit that's too small means constant resupply stops, while an oversized one wastes space and drains more power than necessary. Here's a general breakdown:

  • Compact camping fridge — Suits solo travellers or couples needing space for drinks, snacks and a few perishables. These lightweight units fit easily in smaller vehicles and don't require a large battery setup. 
  • 50L-60L fridge — Provides extra storage for fresh food, meats and beverages, making it an excellent choice for couples or small families on multi-day getaways.
  • 70L+ caravan fridge — Essential for extended trips or larger groups, storing enough food for weeks, but requires a 12V battery system or solar power. Consider a slightly larger fridge for off-grid journeys.

Power consumption and efficiency

Power efficiency is a critical factor when selecting a 12V fridge. A fridge that consumes too much power will drain your battery faster than expected, leaving you with warm food and melted ice packs.

  • Energy-efficient compressor models use 1-2Ah per hour, making them ideal for 12V battery setups with solar input.
  • Higher-draw units (3Ah+) may require additional battery support, such as dual-battery setups or a DC-to-DC charger while driving.
  • Many premium models include eco-mode, which reduces power usage by cycling the compressor at lower speeds when full cooling power isn't needed.

Insulation quality

A well-insulated 12V fridge maintains its temperature longer, minimising compressor run time and extending battery life. Models with thick, high-density insulation, like polyurethane foam, reduce heat penetration and improve efficiency. For the best camping fridges, choose at least 40mm of insulation.

Build quality and durability

A reliable portable camping fridge should be built to handle rough terrain, vibrations and other elements. Here are a few things to keep in mind when looking at build quality:

  • Metal casing is more durable than plastic and withstands off-road bumps better.
  • Shock-resistant design prevents damage from vibrations, especially for 4WD and caravan use.
  • Heavy-duty handles and reinforced corners are a must for frequent movement and transport.

Temperature control and display

Modern 12V fridges have advanced temperature control features that make it easier to manage cooling performance. Digital control panels allow for precise temperature adjustments, helping you switch between fridge and freezer settings with ease. Moreover, Bluetooth or WiFi-enabled controls let you monitor and adjust your fridge remotely using a smartphone app.

Dual-zone vs. single-zone fridges

Single-zone fridges can be used as either a fridge or a freezer but not both simultaneously. These are ideal for shorter trips or when freezing isn't necessary. Dual-zones feature two compartments, allowing you to run one section as a fridge and the other as a freezer. These are perfect for extended off-grid travel where fresh food and frozen supplies must be stored separately.
