A portable refrigerator is a great investment. It is likely to be the most expensive item in your camping bag. This doesn't necessarily mean you need the most expensive refrigerator on the market, it depends on individual requirements.

To make the selection process a little easier, consider how you plan to use your refrigerator.

1. Is a larger refrigerator capacity better?

Where a large family may need 65 liters or more, it usually uses a 40 – 50 liter refrigerator.

Consider the length of your journey(s) and whether you can restock on the route.

Vehicle space can be a limiting factor for the size of your refrigerator.

2. Popular refrigerator brands have good trust

Big brands will have more service agents and parts that are readily available.

A little more money spent now will likely reduce problems in the future.

Big brands come with a better warranty.

Make sure the brand has reputation for the right reason.

3. Refrigerators with good insulation consume less power

Look for refrigerators with thick insulation.

Plastic refrigerators conduct less heat than metal, while white fiberglass provides the best insulation.

Better insulation reduces the workload on the compressor.

4. A quality portable refrigerator will even stand up to Turkey's country roads.

You should be able to stand on the door of a powerful refrigerator. You can ask the salesperson to show you.

Metal enclosures are rigid, ideal for the back of a cabinet.

A good option for terrain where plastic will flex when subjected to impact.

White fiberglass is strong but prone to cosmetic damage, ideal for boating.

5. The compressor is probably the most important part of a refrigerator

The compressor warranty is a good indication of the manufacturer's confidence in their products.

A quality compressor will keep your food cold for years of outdoor travel.

6. Power consumption is a great way to compare the efficiency of 12V refrigerators

A refrigerator's current draw is measured in "w/h" or "amperes per hour".

The best electric refrigerators should be used between 1 – 2 w/h over a 24-hour period.

Power consumption should be based on real world testing. Look at stats like "- 5°C indoor, 32°C ambient, 12 V = 0.89a/h for 24 hours". This means that from a 12V power supply, a refrigerator set to 5°C in a 32°C environment will consume an average of 0.89 amps/hour for 24 hours.

High current draw isn't always a bad thing. Refrigerators such as the Waeco CFX will draw high current in a short time as the compressor quickly lowers the internal temperature. This short burst of high current may be less on average over a 24-hour period than a compressor with a low current draw for longer periods.

7. Features may not be an indicator of quality, but some features are priceless

Battery protection protects your battery from damage, especially useful for your car starter battery, which is your only power source. Look for variable protection. Some refrigerators are set to a very low protection voltage (usually 9.5V) to protect the compressor, but not your battery.

.The ability to set the refrigerator to a certain temperature is very convenient.

.The thermometer monitors the internal temperature of your refrigerator.

.The bottom plug facilitates cleaning.

.Flush mounted cooling elements are located on the side of the refrigerator, providing easier cleaning than bolted elements.

.Removable lid is handy for accessing your fridge in hard-to-reach places!

8. Need a dual-zone refrigerator / freezer?

A refrigerator works as a freezer or cooler. But the two do not work at the same time, whereas a dual zone refrigerator has two compartments and works as a refrigerator and freezer at the same time.

Some dual-zone refrigerators have independent compartments and thermostats that allow you to separately control the temperature of both the refrigerator and freezer.

9. There are many cheap options around, but the important thing is, do you get what you pay for?

That doesn't mean you need the most expensive refrigerator, either.

Cheaper refrigerators can be a great option for occasional use and often come with more features.

Expensive refrigerators must have all the features and reliability to go freely with them.
