Comparison of Portable Compressor Refrigerators and Coolers
There are many types of portable refrigerators on the market. The type you use will depend on how long you need to store your food and the ambient temperature at which the refrigerator will operate.
The most common are compressor portable refrigerators and thermoelectric coolers. Which one is right for you? This can be determined by knowing the operating principle, performance, and drawbacks.
Portable compressor refrigerators
These portable refrigerators actually work the same way as home refrigerators. They are the best option if you need to store food for several days and if the ambient temperature is above 25°C.
They are convenient for storing large quantities of food at the temperature of your choice. However, for larger quantities of food and room temperatures, a hard refrigerator will do. This forces the compressor to stay on for longer intervals, resulting in higher energy consumption.
Temperature control is a useful feature of these refrigerators. This allows you to keep food/drinks at the temperature you want. This feature is not available in most thermoelectric coolers, so it is important to note.
Another factor is the noise generated by portable compressor refrigerators. The noise they produce is greater than that of thermoelectric coolers. However, in many quality new portable refrigerators, it is lower.
In addition, the loudest noise is produced when the unit is turned on, which is the same as that produced by a domestic refrigerator. This is due to the fact that the compressor is working at its maximum capacity when the refrigeration operation begins. However, over time, the temperature inside the refrigerator is maintained, the compressor runs less and the noise decreases.
If you store small amounts of food at temperatures about 40°C below room temperature, thermoelectric coolers are a viable option for you.
They produce less noise than compressor refrigerators because there are no moving parts. However, unlike compressor refrigerators, thermoelectric coolers run constantly and do not shut down.
They consume more energy than portable compressor refrigerators. Most thermoelectric coolers draw 3 to 5 amps of current at 12 volts. This is several times the power consumption of a compressor refrigerator.
Most thermoelectric coolers are not temperature controlled. In fact, thermoelectric coolers are differential and reduce the temperature by a fixed amount relative to the ambient temperature.
An impressive feature, however, is that they can cool and retain heat. This means that food can be kept at warmer temperatures during daytime travel. But of course, just as there are limits to cooling, there are also limits to heat retention.
The energy consumption of thermoelectric coolers depends largely on the ambient temperature. When it is hot, the desired temperature drop cannot be achieved and a lot of energy is consumed. Compressor coolers are very efficient in hot weather.
Thermoelectric coolers are much less expensive than portable compressor refrigerators. However, this reduction in money has a limited cost. You should only choose this solution if you know that food and beverages need to be kept for part of the day and the ambient temperature is not far from the desired temperature of the food.

How To Pick The Best 12 V Portable Refrigerators | Ultimate Guide 2023
The cooling efficiency of portable refrigerators
The most important thing to consider before buying a portable refrigerator is to make sure that, despite all the features it has, it effectively cools the contents inside.
If a refrigerator, despite its large size, cannot cool the food or drinks inside, it is useless.
Sometimes, portable refrigerators have different zones formed with large temperature differences. This aggravates the internal contents. Therefore, favor products with homogeneous and efficient cooling.
Energy consumption and battery operating efficiency
The purpose of buying a portable refrigerator is to be able to transport it efficiently. So it is naturally expected to run on a 12-volt battery.
However, the refrigerator must be efficient to save energy. In order for the compressor to provide the required cold temperature, the power state must be changed to reduce the power input.
If the refrigerator has no battery, this can be an inconvenience when traveling. However, most new portable refrigerators stop refrigerating when the battery power reaches a certain level.
If it's not efficient enough, you'll need to use an additional power source like a portable generator or solar panels. This will increase the cost of the installation and make it less convenient.
Durability and quality of components
You spent your precious money on a product; now you want it to last. You now want it to work for a long time without breaking. It also needs to be able to withstand uneven pavement and slopes.
The compressor is the main moving part of the refrigerator. On slopes and bumpy roads, the compressor will likely be the first to be affected. So you need a durable compressor, and ICECO offers a five-year warranty on the products I recommended.
Also look for durable, long-lasting external and internal housings on your portable refrigerator.
Size and capacity of portable refrigerators
The size you choose your product for also matters. Look for the capacity (in liters or quarts) that best suits the number of your products.
For example, a 4-liter electronic cooler may be sufficient for cooling skin care products and medications. However, if you are planning a multi-day summer trip, you should consider a portable compressor refrigerator of 40 liters or more.
AC/DC Power Compatibility
Expect portable refrigerators to run on 12V batteries. That's why, after all the trips you bought it for in the first place.
But also check its compatibility with AC power.
This is a useful feature, as it eliminates the need for a direct battery connection in places where AC power is available, such as motor homes or boats.
Noise intensity and duration
After the basic features when buying a portable refrigerator, also consider the noise factor. Compressors generally produce more noise than thermoelectric refrigerators.
Try to choose one with minimal sound. However, newer models generally produce less noise and the noise decreases when the desired temperature is maintained.

For example, if your fridge consumes 50 watts and runs for 24 hours per day, its daily energy usage is 1,200 Wh (50 watts x 24 hours). If your location has 5 peak sunlight hours per day, you would need a solar panel with a capacity of at least 240 watts (1,200 Wh / 5 peak sunlight hours).
- Factor in battery capacity: In addition to solar panels, you will need a battery to store the energy produced by the solar panels. The battery capacity should be at least equal to the daily energy usage of the fridge, and preferably a bit larger to account for losses due to inefficiencies in the system.
Keep in mind that these are general guidelines and the actual solar power requirements can vary depending on many factors, including the size of the fridge, the efficiency of the solar panels, and your location. Additionally, you may need to factor in additional energy usage for other appliances or devices. It's important to consult with a professional or do careful calculations to ensure that your solar system is properly sized for your needs.
Does a 12V fridge need ventilation?
Yes, a 12V fridge typically needs ventilation to operate properly and efficiently. Ventilation is necessary to dissipate the heat produced by the fridge's compressor and ensure that the fridge operates at the correct temperature.
