“How much electricity does a mini fridge use” might be a confusing question that you usually encounter when you consider buying a mini fridge for your household, mightn’t it?
As we know, this mini fridge is similar to a normal refrigerator which is specifically intended to keep food and beverages you put in the fridge at a consistent temperature and includes humidity controls, which can cause undesired chemical changes with time.
Therefore, there is an additional cost to possess a mini fridge. With that said, the question is formulated is whether a mini fridge uses a lot of electricity or not? Let’s dive into this blog to get more detailed information!
How Much Electricity Does a Mini Fridge Use?
Mini-refrigerators and fridges are typical names for compact refrigerators. They are typically used in dorms, home offices, guest rooms, and other tiny spaces. The tiny refrigerator’s objective is to lighten the load on the kitchen fridge.
Most people believe that because mini-fridges are small, therefore require less electricity, but this is not the fact. A refrigerator’s electricity usage fluctuates depending on its size, characteristics, function, and durable construction. To comprehend a mini-energy fridge’s usage, we must consider a variety of aspects that contribute to its operating costs.
So, how much power does a mini refrigerator consume? Mini-fridges utilize somewhere around 55 to 85 watts of electricity on average, depending on their insulation and size. With an average price of 12 cents per 1kWh in the United States, running a mini-fridge would cost you between $19 and $29 per year if it works for 1/3 out of the 24 hrs per day.
Is That a Lot Of Electricity?
In fact, when compact fridges are opened, they lose less cold air than ordinary refrigerators. This is due to the reduced volume of mini-fridges, which typically range around 1.7 to 4.5 cubic feet. A normal refrigerator, in contrast, has a capacity of 9 to 30 cubic feet.
When it comes to the size, opening the mini-fridge 7 times a day saves more cold air than opening a regular refrigerator the same number of times. The smaller capacity stores fewer foods and beverages while consuming less electricity than a full-sized refrigerator does to keep all of your beverages cold.
The energy consumption of mini-fridges varies depending on their size, materials, and function. According to Consumer Reports, a 4.5 cubic foot micro fridge costs $27 per year to run, while a 20.6 cubic foot normal refrigerator costs around $47. This is acceptable given that mini-fridges utilize between 233 and 310 kWh per year, compared to 420 kWh for normal refrigerators.
Don’t fall into the trap of believing that the smaller the product, the less electricity it uses. Smaller machines, in fact, require more energy per volume, which means you spend more per cubic foot for cooling space, as seen below:
- 100 kWh / $12.00 for a 60 liter capacity
- 70 kWh / $8.40 for a 40 liter capacity
- 50 kWh / $6.00 for a 20 liter capacity
On top of the mentioned values, a surcharge of roughly 20% can be considered for refrigerators with freezer compartments. Refrigerators that are silent soon quadruple their consumption. The datasheet for many products also includes an estimate of annual usage.
Things That Affects Mini-Fridge Power Use
The actual energy consumed of a micro fridge is determined by a number of variables. These are some of them:
- Settings: This factor can result in higher energy use than is truly necessary.
- Usage: The compressor will have to work harder to keep beverages and food cool if the fridge door is kept open or used frequently.
- Age: Older refrigerators are typically less energy-efficient than newer models with a good rating.
- Location: Refrigerators in warmer climates work at least as much as they should to supply the required cooling power reading the rule of thumb.
- Season: Because the ambient temperature is higher in the summer than in the winter, all mini-fridges usually utilize more power.
- Model: Several models are designed to be more energy-efficient than others, earning an A ++ Energy Star certification, as opposed to a B.
- Size: Even though they are available in a variety of sizes, those with a bigger volume consume more energy.

- kWh per day = Watt-hours / 1000
How Much Will a Mini Fridge Raise My Electric Bill?
The mini-fridge might increase your yearly bill by $20 to $50 depending on its size and insulation levels. However, because these gadgets do not consume electricity continuously, it is nearly difficult to forecast how much electricity your mini-fridge will need. Yet, taking into account the list of factors that influence your energy usage, on the other hand, might give you a general concept of how it works.
In this instance, the best advice is to thoroughly consider each component before purchasing and to keep track of your usage habits as well as the monthly cost. You’ll eventually figure out what makes your temperature rise, how many times you open the door every day, and even how much food, particularly hot things, is in your refrigerator. That’s when you’ll be able to spot a pattern and devise a strategy for making better use of it.
How Many Watts Does a Mini Fridge Use?
A mini-normal fridge’s wattage ranges between 55 and 85 watts, depending on its size. As a result, a mini-fridge consumes far less energy than full-size refrigerators, which consume between 100 and 400 watts every hour. Every refrigerator is rated in watts. It’s the number that’s displayed when they’re turned on, and we can use it to figure how much electricity they use every hour, day, or month.
However, we’ll need kWh to figure out how much it’ll cost to run a refrigerator. These units don’t turn on and off as frequently as larger models. We’ll use a mini-fridge as an instance of how to precisely assess energy use.
Assume your device consumes 80 watts every hour for eight hours each day. Multiply 80 by 8 to get the total watt-hours utilized in a day which is 640 watt-hours. Simply divide 640 by 1000 to get the kilowatts, which equals 0.64 kWh.
That means your monthly electricity usage is 19.2 kWh, and your annual usage is 233.6 kWh. Using the US average with 12 cents for 1 kWh and multiplying 0.64 kWh by 0.12, you’ll have to spend $0.0768 every day. If you want to go any farther, multiply $0.0768 by 30 (1 month) or 365 (1 year) to obtain $2.3 and $28 respectively, which is the total sum you’ll have to pay over time.
How Many Watts Does a Wine Cooler Use?
The wine fridge uses 90 watts of power on average, however this varies depending on the size and cooling method used. A 28-bottle thermoelectric cooler, for example, consumes 70 watts while the compressor unit of the same capacity consumes 85 watts. The compressor in the 32-bottle wine cabinet, in contrast, consumes 85 watts, while the thermoelectric requires an average of 140 watts.
Because they run continuously, thermoelectric refrigerators require more energy than compressor refrigerators do. Because it utilizes more Peltier modules to operate the machine, the thermoelectric refrigeration system for the 32-bottle size uses 140 watts. A modest thermoelectric wine cooler will cost you roughly $40 per year if used properly, whereas a large compressor cooler would cost you over $100.
You can save money on power by doing the following:
- Between a freestanding unit and a wall, there must be some space: It is necessary to have adequate ventilation.
- Use a small thermoelectric cooler to keep things cool.
- Refrigerate in a dark, cool location; avoid heated areas at all costs.
- Open the refrigerator door only when absolutely necessary.
Ways to Save Power Consumption
- Change the desired temperature as follows: Mini fridges are frequently set to a temperature that is far too chilly by default. To measure and adjust your settings, use a thermometer.
- Ensure that your fridge is sufficiently ventilated: Mini-fridges are frequently placed between wall cabinets, requiring more power than usual. This is something you should avoid.
- Use timer buttons to keep your mini-fridge on only when it’s required to keep food and drinks chilled.
Know Exactly How Much Power Your Fridge Consume
The actual amount of electricity used by a tiny fridge is undetermined, but you could use a gadget called a power meter to find out. It displays real-time information and assesses the average speed of electrical energy flow in watts. Power meters are rather inexpensive these days, so it’s definitely worth the expenditure if you’re concerned about your mini-energy fridge’s use.
There are even complex models that can predict how much you’ll have to pay based on your energy consumption. Because the information is already provided, you won’t have to conduct the computations yourself. As a result, you could easily check the electric power your small fridge has already used and alter the temperature if necessary using an electricity meter.
Things to Consider When Buying a Mini-Fridge
You should factor in that you’ll be utilizing the mini-fridge for at least 2 to 3 years when calculating your expense. You can compute the costs of operation over a year by multiplying your provider’s current electricity price per kWh by the annual usage of the fridge.
When you multiply this figure by a factor of two or three, you can calculate the electricity usage in proportion to the purchase price and compare mini-fridges. However, in practice, the useful life is closer to 5 to 10 years. This period’s costs can also be computed. One of the reasons to consider a tiny refrigerator is if you reside in an area where energy costs are high.
Are Mini Fridges Worth It?
Mini refrigerators typically having a capacity of 60 liters or less would be more than enough for a single family. A micro-refrigerator is a fridge with a capacity of 20 liters or less, which is clearly insufficient to service an entire family. Instead, they’re used to chill drinks in the living room or on the terrace, for example.
Please notice that silent refrigerators have a low energy-efficiency rating. A noisy compressor only works on occasion, but the technology in its silent equivalent operates almost continuously but at a far lower volume. In exchange, you’ll be able to use a silent refrigerator in your bedroom without bothering your partner’s sleep.
Wine cooler vs Mini Fridge: What’s difference?
The temperature of a wine cooler goes from 41°F (5°C) to 65°F (18°C), but the temperature of a mini-fridge fluctuates from 35°F (1.7°C) to 42°F (5.5°C). Wine coolers are built to maintain wine fresh by gradually lowering the temperature while retaining the humidity. While mini-fridges are being used to keep popular foods and beverages, they also have the tendency to change the lower humidity.
The level of vibration is the second disparity. Advanced compressor-based cooling or vibration-free thermoelectric cooling are used in wine coolers. Mini-fridges, in contrast, vibrate constantly when the compressor compresses the refrigerant gases.
The interior shelves and layouts are the third distinction between them. Wine coolers have specialized shelves so that bottles of wine can be stored in a safe place. Traditional refrigerators frequently have pre-installed shelves that cannot be modified, whereas wine coolers have dedicated shelves so that bottles of wine can be kept in a safe area. The aging process can be sped up and made more efficient by maintaining the bottles in place.
“How much electricity does a mini fridge use” is a question that should be made clear because snacks, cooked lunches, coffee, and beverages are the most typical items stored in mini freezers.
As a result, owning a mini-fridge is a fantastic idea. We can see specifically how much electricity these appliances utilize in this post, as well as what factors influence consumption as well as how to reduce it.
We also mentioned that if you want to accurately monitor your minifridge, you can use gadgets like a power meter, which provides real-time energy consumption information. I hope this information has given you a better understanding of how much energy a mini-fridge consumes.
