You’ve probably wondered how much electricity a mini fridge needs if you’re thinking about buying one. As a result of its compact size, it must use less energy, right? All of your burning questions will be addressed today, starting with “how many watts does a tiny refrigerator use?” You may be surprised by the response.


It’s time to get to the bottom of what a watt is before we go any further. That’s all I can say. Don’t worry, we won’t go into too much detail or use a lot of jargon.

Watts are units of electrical power measurement. Indicators show how much energy a machine consumes. The wattage power of each gadget in your kitchen is often marked on the equipment itself.

Calculating how much energy you use is also based on watts. There will be a reference to kilowatt-hour (kWh) on your monthly electricity bill. The wattage required to power a larger appliance rises proportionately. Your yearly or monthly payment amount will be determined by this.

How Many Watts Does a Mini Fridge Use


The typical micro fridge consumes 50 to 65 watts of power. However, this isn’t as simple as it appears. More than one model may fall within or even exceed this spectrum of usage. One model uses up to 100 watts of power!


Numerous variables have an effect on the wattage consumption of tiny refrigerators.

In the first place, the size of the refrigerator is critical, as larger models consume more watts.

Your tiny refrigerator’s energy efficiency is also affected by the quality of its insulating system. Refrigerators that are good at retaining the cold use less electricity.

As a final point, older models are more power-hungry than their newer counterparts. That’s why upgrading to a more energy-efficient and modern appliance may be worth the extra money.

Finally, the way you stock the mini fridge is important. Refrigerators work overtime and use more power when they’re overcrowded.


How do you tell how much power your compact refrigerator is consuming if every mini fridge is different? With this method, there is no guesswork and it is straightforward.

Start by going through your pantry and refrigerator. A sticker with technical information should be affixed to one of the side walls. There are some numbers that we’ll be analyzing, as well.

A “volts” and “amps” number should be displayed. The actual wattage number can be found by multiplying the two numbers. Voilà.

You could also read over the instructions in the user’s manual (if you still have it). Everything you need to know, including wattage, is right there.


Full-size refrigerators use more electricity than tiny fridges. This is primarily due to their immense size.

Mini refrigerators, on the other hand, typically have a volume of 3 cubic feet, whereas the average refrigerator has 23 cubic feet. It’s because of this significant difference that refrigerators run between 100 and 250 watts on average.


In terms of energy consumption, small fridges are significantly more efficient than full-size refrigerators. They are able to preserve food at the same temperature while consuming less energy.

However, not all models are as energy-efficient as they appear to be. If you get one of the more recent models, you can save quite a bit of money each year. However, if you’re not careful, buying cheap appliances might empty your bank account. Look for Energy Star-certified products.


How much electricity does your mini-fridge use will help you figure out how much it will cost to run it. We’re sorry, but we can’t provide you a definitive response.

The reason why is that mini fridges don’t run all day. They’re not squandering energy at all times. As a result, they only work in short bursts. To keep the fridge at a constant temperature, the engine operates until the temperature drops to a certain point, then shuts off. Your mini-fridge is likely to run for a third of the day on average.

So, to get a wattage-hour number, multiply the wattage of your mini fridge by eight hours (a third of a day).

That figure will be divided by 1000 to get kilowatt-hours, the most often used unit for calculating electric costs.

You can figure out how much it costs to run your mini-fridge by multiplying it by your local kWh rate.


Let’s have a look at an example to make things clearer.

Assume you own a 100-watt mini-fridge. It consumes 800 watt-hours of power if it runs for eight hours a day (a third of a day). This equates to about 0.800 kilowatt-hours. Running this little fridge would cost you $3.20 per month if the average kWh cost in the United States is 13.31 cents. That works out to about $38.4 a year.


Fortunately, there are steps you may take to further reduce the power consumption of your mini fridge. Spoiler alert: most of this is stuff you were taught to do as a child by your parents or guardians.

How Many Watts Does a Mini Fridge Use (with Wattage Calculator) (November 2022)


Your mini-temperature fridge’s rises every time you open and close the door. With the engine working overtime, it consumes extra energy in an effort to counterbalance this. As a result, the more energy you consume, the more money you’ll have to pay.

Avoid opening your mini fridge all the time to see what’s inside if you’re trying to save money and the environment.


Keep in mind that you’ll be forced to pay more in annual energy costs when you leave the doors open for long periods of time. When you leave your fridge door open for an extended period of time, it emits a beep.


It’s a terrific method to save money to store your food and beverages neatly. Start by finding what you’re looking for fast and simply. This allows for more uniform cooling of all shelves in the fridge, as the cold air is able to move more freely. Reduces energy usage by preventing the engine from overworking to bring appliance temperature down to a safe level.


It’s possible you’ve observed ice buildup on the shelves and walls of your mini-fridge from time to time. It’s typical, yet you still have to put up with it and move forward regardless. If you don’t, the tiny fridge’s engine will have to work more than usual to bring the temperature down throughout the appliance.

For your convenience, we’ve detailed exactly how to defrost a tiny fridge in just one day!


If you’re looking to save money, place your mini fridge in a cooler location. When it’s hot outdoors, the small fridge works harder to compensate (and wasting more energy and money).

Keep it out of the way of heat sources (such as tea kettles and instant pots) and out of the way of cabinets.

How many watts does a refrigerator use?

The typical household refrigerator consumes between 350 and 780 watts.

According to various circumstances, including the type of fridge you own and its size and age, the kitchen’s ambient temperature as well as where you install the refrigerator, refrigerator power consumption might vary widely.

The power needs of various types of refrigerators vary. New Energy-Star refrigerators, for example, run up to 9% more efficiently than other models and substantially more so than older equipment. It takes less power to run a mini-fridge than it does a full-sized kitchen refrigerator. As a bonus, top-mount refrigerators are more energy-efficient than their counterparts on the other side of the room.

How Many Watts Does a Mini-Fridge Use?

Mini-fridge power requirements range from 50 to 100 watts, depending on cooling capacity and manufacturer.

Your mini-power fridge’s usage will be indicated in your owner’s handbook, much like other appliances (in watts). Advances in technology have made it possible for newer versions to keep food and beverages refrigerated while consuming less electricity than previous generations. The average compact refrigerator only runs for eight hours each day, or one-third of the day.

Does a mini-fridge take much electricity? The frequency with which you use or leave the mini-fridge plugged in will have an impact on this. In accordance with Energy Star, the vast majority of small refrigerators today consume no more than 310 kWh per month. If a mini-fridge fits your needs for temperature-controlled storage, you can save a lot of money each year by switching from a larger appliance.

Estimate your refrigerator’s power consumption

When it comes to figuring out the amount of electricity your refrigerator consumes, there is a simple method. Look for the volts and amps on the sticker inside your refrigerator to find out how much power it consumes. Figure out how many watts you use by multiplying these numbers.

The total wattage of an ancient refrigerator, for instance, might be as high as 747.5 if it had a voltage and amperage of 115 V and 6.5 amps. As an example, an Energy Star-certified refrigerator may use only 117 V and three amps, resulting in an output of 379.5 W.

As a result of their constant on-and-off operation, refrigerators utilize substantially less energy than other household appliances. To get a general idea of the running watts, multiply the wattage you computed by three.

To calculate your power bill, all you have to do is know how many watts are in your refrigerator.

  • If your fridge operates 24 hours a day, multiply the running power by 24.
  • To get kilowatts from watts, multiply the result by 1,000.
  • Determine the cost per kilowatt-hour by checking your electricity bill. EnergyBot can also be used to compare local energy prices.
  • In order to get the cost each day, multiply kilowatt-hours by the price per kilowatt-hour.
  • To get an approximation of the monthly cost, multiply 30 by 30 or 365 by 365.

In this example, we’ll show you how the arithmetic works:

750 watts / three equals 250 watts per day.

250 watts multiplied by a 24-hour period equals 6,000 watts.

6,000 watts divided by 1,000 watts is 6 kilowatt hours

Daily cost is equal to 6 kWh times $0.10

There is a total cost of $18 a month or $219 a year for the refrigerator in the scenario above.

Best energy-efficient refrigerators

It is possible to significantly reduce your electricity usage by purchasing an energy-efficient refrigerator. In order to save electricity, you may have to compromise on the size of your refrigerator. Whatever the scale of your project, comparing energy use and Energy Star ratings is critical.

A yellow Energy Star label with “Energy Guide” at the top will appear on appliances. Using this label, you can see an estimate of how much energy you’ll use in a year (kWh). The more energy-efficient a device is, the less it is used.

Using a generator to run your refrigerator

Consider a generator for your refrigerator if you live in an area where power outages are common or you’ve lost power due to a storm. However, there are a few things to keep in mind prior to turning on the backup generator.

What size generator do I need to run a refrigerator?

You must first know how many watts your refrigerator consumes, as mentioned in the preceding paragraph. It takes more energy to start your generator than it does to keep running. The initial wattage of a 750-watt refrigerator, for example, might be as high as 1,200 watts. Using a 1,500-watt generator, you could power your fridge. Ensure that your starter wattage is correct by consulting your product’s documentation.

Will a 5,000-watt generator run a refrigerator?

If you have a 5,000-watt generator, you should have plenty of electricity to run a refrigerator. Starting at 2,000 watts, the majority of refrigerators in the home use.

Can a 2,000-watt generator run a refrigerator?

According to the size of your refrigerator, you should have no problem powering it with an adequate 2,000-watt generator. Make sure to check your fridge’s wattage and starting wattage before using the generator to avoid overheating it.

Can a generator damage a refrigerator?

Even while refrigerators aren’t known for being particularly vulnerable to power surges, they can nonetheless be damaged by generators. If your generator is too tiny to support the initial wattage of your fridge, it could overheat.
