The wattage of a mini-fridge varies depending on its cooling capacity and the manufacturer, although the majority of models need between 50 and 100 watts of electricity.
The power consumption of your mini-fridge will be mentioned in your owner’s handbook, much like the power consumption of other appliances (in watts).
Recent technological advancements enable newer models to keep food and beverages cold while using less energy than models that were available on the market a few years ago.
The reason for this is because most compact refrigerators only operate for approximately eight hours a day, or one-third of the time.
What is the energy consumption of a small fridge?
This will be determined by how often you use the mini-fridge and how long you leave it plugged in.
According to the Energy Star website, the vast majority of compact refrigerators now use 310 kWh or less.
Provided you use a mini-fridge for temperature-controlled storage rather than a bigger appliance, you may expect to save a substantial amount of money each year if the smaller appliance fits your needs.
Power consumption of a refrigerator or freezer when it is first turned on vs while it is running
Appliances like refrigerators and freezers are driven by electric motors, which need more power when they are first turned on (thus the term “starting watts”).
The actual power consumption varies significantly based on the refrigerator/freezer size, energy class, temperature differential, and other factors such as these.
Older, bigger machines needed up to 700-1000 watts of operating power and 2000-3000 watts of starting power to operate.
If you have a big home refrigerator or freezer that consumes more than 500 watts, look into its energy star rating.
Purchasing a new, more energy-efficient appliance may result in significant energy (and money) savings over a period of time if done properly.
We mention a “certain amount of time” since the length of this period is determined by local electric energy costs, the power differential between units, and other factors.
Modern refrigerators and freezers are usually required to include the following features:
For example, a big household refrigerator requires 200-400 operating watts and 1000-1200 beginning watts.
– a typical household refrigerator consumes 100-250 watts when operating and 700-1000 watts while starting.
For a modest residential refrigerator, the power requirements are 75-150 operating watts and 400-600 beginning watts.
The following are the power requirements for small home and RV refrigerators: 40-50 operating watts, 80-120 beginning watts.
Note: The quickest and most accurate way of determining the real power needs of your device is to locate and inspect a tiny plate on the rear of the unit that lists the unit’s power specifications.
Calculating the Specific Energy Consumption
As a result of the fact that refrigerators cycle on and off during the day to maintain temperature stability, you shouldn’t base your estimates on a 24-hour period.
According to the United States Department of Energy, most refrigerators only operate at full capacity for approximately 8 hours per day (or about one-third of the time they are plugged in).
This figure, on the other hand, may fluctuate based on a variety of variables, including:
The frequency with which your refrigerator is opened: if you or your family members are constantly opening the refrigerator to get food, it will need to run to cool down more often.
Ambient temperature: if your refrigerator is located in a warm area of your home, it may need to run longer; conversely, if it is located in a cool area, it may need to run less often.
Season and environment: Refrigerators tend to operate less during the winter or in cold regions, and more during the summer or in warm areas, depending on the season and climate.
Refrigerator temperature settings: You may change the temperature settings on your refrigerator; however, lower temperature settings will use more electricity.
Freezer: If your refrigerator includes a built-in freezer, it may use more electricity or operate for a longer period of time than usual.
Let’s take the identical example from before to illustrate this point.
If the refrigerator consumes an estimated 332 kilowatt-hours per year, it equates to 0.91 kilowatt-hours a day, according to the manufacturer.
In accordance with the typical refrigerator’s power and use, which is approximately 1-2 kilowatt-hours per day, this figure is accurate.
When converting this figure to a wattage, first multiply the number of kilowatt-hours (0.91) by 1,000 to get 910.
Next, divide this figure by eight, which is the usual amount of time a refrigerator runs in a day, to get the average wattage of your refrigerator.
In this particular instance, the answer to the question
“What is the average operating wattage of a refrigerator?” is about 113.75 watts.
To figure out how much it will cost each month, just divide the anticipated 332 kilowatt-hours per year by 12.
This leaves you with about 27.67 kilowatt-hours each month, which equates to approximately $3.32 per month.
You may also just divide the anticipated annual cost by 12, which will give you the same answer as the previous method.
What Should I Do If I Don’t Have My EnergyGuide Sticker with Me?
If you’ve misplaced your EnergyGuide sticker but still want to figure out how much energy your refrigerator consumes, you may not be out of luck.
The EnergyGuide requirements for your refrigerator may be found online if you know where your refrigerator’s serial number is located (it’s typically on a sticker someplace on or inside the refrigerator; look inside the refrigerator door or on the back of the unit).
If all else fails, you can always buy a plug-in energy consumption meter to keep track of your use.
This device would be installed in the socket that connects your wall outlet to your refrigerator.
If you’ve ever wondered, “How many watts does a refrigerator consume exactly?”
This will be answered by an electrical consumption monitor.
It may also be very useful in detecting energy loss problems for the same reason.
Calculate the Electricity Usage of your Refrigerator
The amount of energy used by your refrigerator may be easily calculated if you know how much electricity your refrigerator consumes on a regular basis.
To find out how much power your refrigerator consumes, look at the label on the inside of your refrigerator and count the number of volts and amps it has.
To find out how many watts your refrigerator consumes, multiply these two figures together.
In the case of an ancient refrigerator, the voltage might be 115 V, the current could be 6.5 amps, and the total power could be 747 watts.
A modern Energy Star-certified refrigerator, on the other hand, could have 117 V and 3.3 amps, resulting in a wattage of 379.5 watts, according to the manufacturer.
Due to the fact that refrigerators cycle on and off throughout the day, their operating wattage is considerably lower than that of other appliances.
To get an approximate approximation of the operating wattage, divide the wattage you computed by three to get an idea of the total wattage.
Now that you know how much energy your refrigerator consumes, it’s simple to estimate your electricity expenses.
To reflect the 24 hours a day that your refrigerator is operational, double the operating wattage by 24.
To convert watts to kilowatts, multiply the number by 1,000.
Check your energy bill to see how much you are charged per kilowatt-hour of use.
You may also use EnergyBot to compare energy prices in your local region if you live in a rural location.
Calculate the cost each day by multiplying the number of kilowatt-hours by the price per kilowatt-hour.
Calculate the monthly cost by multiplying it by 30, and the yearly cost by multiplying it by 365.
Here’s an illustration of how the arithmetic is split down:
- 750 watts divided by three equals 250 watts per day
- 250 watts multiplied by 24 hours equals 6,000 watts
- 6,000 watts divided by 1,000 watts equals six kilowatt hours.
- 6 kWh multiplied by $0.10 per kWh is $0.60 each day.
Powering the refrigerator costs $0.60 per day in the case above, which equates to $18 per month or $219 per year in electricity expenses.
Refrigerators that are the most energy-efficient
Investing in an energy-efficient refrigerator may have a significant impact on your ability to reduce your power use.
Unfortunately, reducing your use generally entails reducing the size of your refrigerator in order to increase its energy efficiency.
Comparing energy consumption and Energy Star ratings is critical, regardless of the size of the project.
Equipment will be identified by a yellow Energy Star label with the words “Energy Guide” at the top.
This label makes it simple to view an estimate of your yearly energy use (kWh). The lower the consumption, the more energy-efficient the system.

5 IMPORTANT ENERGY SAVING SUGGESTIONS FOR YOUR Fridge
According to Energy Star, certified refrigerators use 20 percent less energy than ordinary models, compared to their counterparts.
Not ready to make the financial investment required to upgrade your home?
Here are some free and low-cost suggestions from Payless Power to assist you in getting the most out of your existing appliance’s energy efficiency.
1. Keep it Out of Direct Sunlight
A cool location away from any heat sources, such as big windows that get a lot of sunlight or the oven, is the ideal place to store your refrigerator.
Already working hard to evacuate hot air, refrigerators are put to the test when the air around them is scorching.
2. Move at a Rapid Pace
For example, avoiding leaving the refrigerator door open may help you break negative habits and save money on your energy bills.
As long as you leave the fridge door open, the compressor is activated, increasing the amount of electricity required to run the appliance.
Make every effort to get what you need from the refrigerator as soon as possible and close the door as quickly as feasible.
3. Select the Appropriate Temperature.
The use of a refrigerator or freezer set at an extremely low temperature result in significant energy waste.
Make certain that the internal thermostats for the refrigerator and freezer are adjusted to the optimum temperatures of 37 degrees Fahrenheit for the fridge and 0 degrees Fahrenheit for the freezer
4. Keep it Clean on a regular basis.
Do yourself a favor and include regular cleaning of your refrigerator every three months on your to-do list of tasks.
Remove the refrigerator from the wall so that you may clean beneath the fridge as well as the coils on the back, and then remove and clean the kick plate on the front of the refrigerator.
When your refrigerator has the capacity to breathe more easily, it will undoubtedly use less energy while running.
5. Only ice-cold food, and enough of it.
Take the time to allow your hot leftovers to cool before placing them in the refrigerator to avoid overworking your refrigerator compressor.
As a result, only room temperature or cold food should be stored in your refrigerator. Additionally, make sure that your freezer is at least three-quarters full so that it does not have to work harder to chill down empty space when it is not needed.
6. Are you willing to spend a little money? Gaskets should be replaced.
It is critical that your refrigerator does not leak any chilly air into the room.
This may result in a significant waste of energy.
You should replace the rubber gaskets surrounding your refrigerator and freezer if you notice that they are no longer effectively retaining cold air in the refrigerator or freezer.
Our Final Thoughts
On the whole, the monthly cost of operating a refrigerator is quite modest, but the amount you pay may vary depending on the size and cost of your fridge.
If you want to save money on energy, your best bet is to either switch to a newer, more energy-efficient refrigerator or give your existing appliance some much-needed repair.
If you choose any of these choices, you should see a significant reduction in your monthly energy cost.
Frequently Ask Questions
Is it possible to operate a refrigerator with a 2000 watt generator?
As long as the generator’s watt allowance is more than the beginning watt consumption of the refrigerator, running a refrigerator on a generator is completely safe.
Because the typical starting watts of a refrigerator are between 800-1200 watts, a generator with a capacity of 2000 watts is adequate.
Will a 1500-watt generator be able to power a refrigerator?
As a rule of thumb, multiply the running wattage by 1.5 to get the wattage required for the refrigerator to begin operating.
Suppose your generator has a rated capacity of 1500 watts.
It should be able to meet the 1,050-watt beginning requirement of the refrigerator in the example and continue to operate the unit without issue.
Is it possible to operate a refrigerator with an inverter?
A refrigerator is an important appliance, and it’s usual to ask whether it can be powered by a 2k watt inverter connected to your solar system, which is a valid question.
If your mid-sized refrigerator consumes up to 1200 watts of starting electricity and is ENERGY STAR certified, you may operate it on your solar panel system.
