A mini-fridge is a really cool device (pun intended). Imagine cooking at home and not having to go inside to get your drinks.

Just go to the mini-fridge and pull out an ice-cold drink. It’s best to step away from the grill and keep an eye on the steak to make sure everything is perfect.

Later, one of your friends, impressed by your mini-fridge and its convenience, will ask you how many watts it consumes. Well, you’ve never thought about it and you don’t know.

Pull out your phone, do a quick Google search and you’ll see that the average mini-fridge is between 50 and 100 watts.

Depending on the manufacturer of the compact refrigerator, which is another name for a mini-fridge, and depending on the size of the mini-fridge, the power varies.

Number of watts used in the mini-refrigerator

Exactly how many watts does a mini or compact refrigerator consume? The average range has already been mentioned, but other factors must be taken into account to determine the amount of energy actually consumed over the long term.

Factors such as the insulation of the refrigerator, the near temperature and the frequency with which the refrigerator is opened have an influence.

If the refrigerator is not well insulated, the internal temperature in its vicinity will be more easily affected.

This is one of the main reasons why you don’t want your refrigerator next to the stove, for example. You need to make sure there is enough distance between them.

Not only will you save money on your refrigerator, but you will also save on energy consumption, as it takes less time and less energy to bring the refrigerator to an optimal temperature.

With good insulation, cold air leakage is very low, so the refrigerator has to run for less time to maintain this internal temperature.

After all, many modern mini-fridges only work 30-50% of the time. Another factor to consider is how often the refrigerator is opened during the day.

Every time the refrigerator is opened, a lot of cold air comes out, which means it has to run more often to maintain an optimal temperature. The temperature setting also influences energy consumption.

What is the energy efficiency of a mini-fridge?

The next question you might ask yourself is: what is the energy efficiency of a mini-fridge? Let’s take a look at that, shall we? There is no doubt that a mini-fridge consumes much less energy than a standard size refrigerator. We know that the power output of a mini-fridge is between 50 and 100 watts.

In contrast, a standard refrigerator consumes between 100 and 400 watts, or about 1,575 kWh per year. A mini-fridge, depending on its size, consumes about 292 kWh per year.

These are approximate figures because, as mentioned above, factors such as brand, outdoor conditions and frequency of opening influence power consumption.

Comparison between a mini-fridge and a full-size refrigerator

Based on these figures, can we say that a mini-fridge will consume less energy? It seems so, but appearances can be deceiving.

Studies have shown that large refrigerators are actually more energy efficient than their smaller counterparts, if you look at the figures we just shared and calculate them using energy consumption per cubic foot.


It is relatively easy to find out the power rating of a mini-fridge by reading the owner’s manual or the back of the product, or by doing a quick Google search.

However, I believe the main reason you are reading this article is to determine the impact of a particular power on total energy consumption.

I explained that the number of watts a mini-fridge uses depends on several factors, such as brand, insulation layers, ambient temperature and how often the fridge is opened.

If you include this in your calculations, you will get a rough estimate of how much energy your mini-fridge consumes per year.

Frequently Asked Questions

How much energy does a mini-fridge consume?

Most mini-fridges consume between 80 and 100 watts per hour when in operation. Assume the refrigerator runs for 8 hours a day at 80 watts. Multiply 80 by 24 and you get 640 watt hours per day. Household electricity consumption is measured in kilowatt hours.

How many watts does the mini-fridge consume per day?

In general, the energy used by a mini-fridge is measured in watts. Most refrigerators consume between 80 and 100 watts per hour of operation, but this can vary depending on brand, size and many other factors. If a refrigerator consumes 80 watts per hour and runs for 8 hours per day, it will consume almost 640 watts per day.

Will a 1000 watt inverter work on a mini-fridge?

The inverter is capable of handling up to 1000 watts of continuous power, which should be more than enough for your mini-fridge.

Can a 2000 watt inverter run a mini-fridge?

Yes, a 2000 watt inverter is capable of powering refrigerators that typically require 1200 to 1500 watts.
