Does A Mini Fridge Use A Lot Of Electricity? [Answered]

Living alone as a bachelor has its demerits. You’ll have to take care of everything on your own. And as a bachelor, keeping a big refrigerator is completely unnecessary. You may just utilize a mini-fridge to save money on your power bill. But the question is-

Does a mini fridge use a lot of electricity?

On average, mini-fridges consume about 55 to 85 watts per hour. It’s very less compared to a normal fridge. It’s actually quite less overall. This means your annual electric bill due to your mini-fridge will be less than $57-$87. 

This is just a briefing about the power consumption of a mini-fridge. If you want to learn more about how much electricity it uses, just scroll down.

Let’s get into the details!

How Much Electricity Does A Mini Fridge Use?

Mini-fridges in general use about 55 to 85 watts per hour. It is determined by the size and insulation level of the refrigerators. The average price of 1kWh is 12 cents. Considering you run your fridge 24/7, it’ll cost you $57 to $87 annually. 

This energy consumption can of course increase in the case of a different model. It always varies between one fridge and the other. 

But, there’s one thing that you should know is no fridge runs 24/7. You might keep them on, but when the inside of the fridge is cool, it doesn’t run. Basically, your fridge won’t even cost you $57 to $87 of your electric bill. We’ve assumed this so that you can be on the safe side. 

Is This Too Much Energy Consumption?

We’ve already told you that a mini-fridge uses 55 to 85 watts per hour. If you live in the US then you also know your individual electricity bill for the mini-fridge. 

But, you might wonder if this energy consumption is too much or not. Well, no it’s not. Your minifridge on your countertop costs way less consumption, unlike a normal fridge. If you were to use a normal-sized fridge, your electricity bill would’ve been 2-3 times more. 

How Can You Save Electricity Using A Mini-Fridge?

We’ve already said before that a mini-fridge uses 2-3 times less electricity. However, a mini-fridge may conserve power in other ways as well. 

There’s one more aspect that affects energy use. When you open your refrigerator, an amount of cold air leaves from it. The fridge then has to use some power to bring the temperature back to normal inside the fridge. 

Since mini-fridges are small, they lose less cool air. And since they lose less cool air, they use less electricity to regain the coolness. 

On average, the volume of a mini-fridge is 2.5 cubic feet. But, a normal fridge can be 23 cubic feet on average. You can only imagine the difference in their stature.

Just by using a mini-fridge, you’re saving a lot of electricity. And if you adhere to the tricks of saving energy, you’ll save a lot more. We’ll be getting to those tricks later on. 

Power Consumption Factors Of A Mini-Fridge

When it comes to power usage, there are a number of aspects to consider. This is applicable to almost all sorts of electronic devices. Especially when the electrical outlet is hard to plug-in.

The same applies to mini-fridges as well. Now, let’s look at the factors that affect the energy consumption of mini-fridges-


The make and the model of a mini-fridge is the first factor that affects energy consumption. You’ll notice that your mini-fridge has an energy star rating. A++ means it’s more efficient than a mini-fridge with a B rating.


The energy consumption of a mini-fridge can easily change with the changing of seasons. Since it’s hot and humid in summer, it’ll naturally use more energy to keep everything cool. But in winter, that power consumption is greatly reduced. 


The location of your mini-fridge can easily affect energy consumption just like season change. If your mini-fridge is in a warm place, like in direct sunlight it’ll use more power. The compressor could overheat and the refrigerator breaker would trip.


Many people might not know this, the more aged your mini-fridge, the less efficient it is. Over time the resistors lose their efficiency. And thus, they consume more energy. 


The size of a mini-fridge has a big impact on how much energy it uses. The energy usage of your mini-fridge might be affected by the volume of your mini-fridge.


The mode in which you keep your mini-fridge also plays a role. There’s a dial on your mini-fridge by which you can control the power. The higher the dial is at, the more energy it’ll consume. 

Measuring Your Fridge’s Energy Consumption

Do you want to know precisely how much electricity your mini-fridge uses? We’ve got the ultimate solution for you. For this process, you’ll need a power meter or a wattmeter.

Here are our suggestions for a quality power meter-

Product 1
Product 2

This is the cheapest and easiest option you have for measuring the energy consumption perfectly. What these power meters do is, show you real-time information of the energy consumption on screen. 

You might also be able to get information on a group of devices. However, this is dependent on the brand and type of your power meter. And then there are some expensive ones where you can even input the price per watt. And they’ll directly show you your bill. 

To measure your energy consumption, plug this device into your mini-fridge. Then you can just let it stay there for 24 hours. After that, you can just plug it out and view all the information for yourself. 

How To Save Energy Consumption?

There are some ways you can save that electric bill of yours. We’ve come up with three simple strategies for you to save electricity. Let’s look at them though-

  • Timer Switches: There are timer switches on fridges. Keeping it on will let the fridge use energy only when it’s needed. 
  • Adjusting Temperature Settings: You’ll sometimes notice your fridge cooling too much. You can use a thermometer and measure the temperature. 
  • Maintain Proper Ventilation: When you place your fridge in a very closed space, it doesn’t get the space to ventilate. That’s when it uses too much power to ventilate. You should avoid this. 

Well, we’ve come to the very end of our article. We hope our take on the mini-fridge power consumption will help you get a clear idea.


Question: Is it safe to keep mini-fridges in the bedroom?

Answer: Yes it’s completely safe to keep your mini-fridge in your bedroom. The loud noise could be slightly problematic for your sleep though. 

Question: Is it okay to keep mini-fridges turned off?

Answer: If your plan is to keep your mini-fridge turned off for parts of the day, don’t. The inside will reach room temperature and the fridge will have to work hours to cool up. 

Question: What places should I avoid keeping my mini-fridge?

Answer: You should avoid places that are close to a heat source. Like direct sunlight, stove or radiator. The compressor of your fridge could overheat. 


Now you have the answer to your question, does a mini fridge use a lot of electricity? We attempted to be as thorough as possible.

Hopefully, our guide has answered all your questions regarding this. 

Good Luck!
