How Many Watts To Run A Fridge? 2 Important Tips You Need To Know!

How many watts to run a fridge? A fridge needs 350 to 780 watts to work and operate. This range is the average usage according to the internet. However, the number of watts depends on the type, model, and size of the refrigerator. This article will discuss some of the information you must know.

Even though your fridge is always switched on or operating, it consumes a fraction of energy like other devices consume. Although your washing machine consumes more or less five to six times the amount of energy as your fridge, you are probably to use it for fewer periods monthly. Wattage and power dissipation usually determines the amount of energy used. Therefore, it gives you an idea of what your electric bill will be.

How Many Watts To Run A Fridge?

To answer your question: How many watts to run a fridge? The standard household fridge consumes 350 to 780 watts of power. However, fridge energy consumption is affected by a variety of aspects. It includes the type of refrigerator you have, its shape and size, the temperature difference in your home, the array of fridges you have, and its location.

All elements mentioned earlier influenced the amount of power your fridge uses. Thus, each refrigerator has a different number of watts. In addition, varying models of refrigerators hold different amounts of energy.

A sustainable Technology approved fridge, for instance, is up to 9% more reliable than other versions. Moreover, it is substantially more competent than earlier ones. On the other hand, mini-fridges use less energy than the full-sized or ordinary fridge.  Furthermore, top-mount refrigerators use less power than side-by-side refrigerators.


How To Calculate The Electricity Cost Of My Fridge?

If you’re curious about how much energy your fridge consumes, there’s a simple method to figure it out. First, check the number of voltages and amperage inside your fridge. This action is the way to determine how much power it has. Next, multiply these figures to find out how much wattage your refrigerator takes.

An ancient fridge, for reference, may have 115 Volts and 6.5 amperages, totaling 747.5 watts. A modern Energy Star-approved refrigerator, on the contrary, may have 117 Volts and 3.3 amperage, or 379.5 watts. You can see their difference. On the other hand, fridges have a much lower operating watt since they turn on and off each day. So to get a general approximation of the current watts, split the watts you computed by three.

It’s simple to calculate your power bills now because you know the watts of your fridge. To reflect the 24 hours per day that your refrigerator operates, double the operating watts by 24. To switch watts to kilowatts:

  • Multiply by 1,000
  • Analyze your power statement to see how much for each kilowatt-hour you spend
  • Compare the value each day by multiplying kilowatt-hours by the amount of a kilowatt-hour


Can I Use A Generator To Run My Fridge?

Yes, you can use a generator to make your fridge operate. Sometimes, we cannot escape from unexpected circumstances like brownouts in our homes. Since we have frozen food and beverages, we need to turn on our refrigerator. Thus, it would help if you used your generator. Furthermore, some people in camping sites tend to bring a fridge to store their food. Since they are in a place with no supply of energy, they must incorporate a generator.

However, a specific number of watts a generator must produce to run your refrigerator and prevent overloading. Usually, your generator must produce 2000 to 5000 watts. These number of watts are ideal for running your unit. Therefore, you must know how many watts to run a fridge before using a generator.

On the other hand, use a generator for your fridge if necessary. Since it only has a minimal amount of staring watts, it may overheat. Thus, it can cause damage to your refrigerator.


2 Tips On How To Spend Less Electricity Of Your Fridge

There are things you need to do to lessen the amount of power and energy your fridge consumes. However, you only need to change some of your habits. Here are some tips on how to reduce the power usage of your fridge:


Tip #1. Keep the door close

To reduce energy consumption, you must keep the door close. When you tend to get food or a drink, think of it ahead of time.  The fridge consumes more electricity if you let the door stay wide open since the fridge needs to maintain its temperature. So, grab the things you need in less than 10 seconds to conserve energy.


Tip #2. Buy a new fridge

Old fridges consume a lot more energy than modern ones since their components are not made to come out as energy saving. However, because of technological advancements, modern units tend to use less energy. Thus, purchase a new fridge if you want to spend less.



You must know how many watts to run a fridge as this knowledge will help you spend less and monitor your expenses. Moreover, remember the two essential tips said above. Finally, do not also forget to take care of your fridge! As mentioned above, mini-fridges are also a good option. If you want to save energy, learn what size of mini-fridge is suitable for your dorm.
