Lights, refrigerators, freezers, television, air conditioning, and slum pumps can all be affected by power outages. Portable generators (gasoline, propane, dual fuel) or solar powered power station can be bought to provide substitute power to your appliances.
Also, if you’re going camping and want to power your mini fridge, router, fan, laptops or smartphones, and tv, you’ll need backup power.
But the generator must be of sufficient size to start the appliances and equipment you wish to use.
People need their refrigerator and freezer even in the event of a power outage. During a blackout, dual fuel or battery powered generators are frequently used to power your average refrigerators and freezers.
Portable power stations may be charged using solar panels and are best used indoors, such as in apartments, whereas dual fuel portable generators are best used outdoors, such as while camping or tailgating in an RV.
The most important question for anyone considering using a generator to power a refrigerator is
What Size Generator Do You Need to Run a Refrigerator and Freezer?
To begin, determine how much power your refrigerator or freezer consumes. Older appliances can consume up to twice the amount of energy that a newer, more energy-efficient model of the same size requires. Let’s start by determining the size of generator you’ll require. Frequently, a sticker detailing the refrigerator’s power requirements may be found inside the door.
The number of amps required by your appliance is what you’re looking for. 6 amps is the label on this one. Assuming that the appliance is plugged into a regular 120-volt wall outlet, multiply the 6 amps by 120 V to get the average running watts, which in this example is 720 watts. Refrigerators and freezers require an extra surge of power when the compressor starts, which is usually 3-4 times the running watts. So,
Can a 2000 Watt Generator Run a Refrigerator?
Yes, if it has a starting watt of 500 or less. A typical refrigerator uses 700 watts and has a starting wattage of 2,100 watts. That means the total starting wattage is 2,800W. Can this fridge be run by a 2,000W generator? It is not going to happen. A 3,000W generator, on the other hand, will do.
Starting watts, not running watts, is the bottleneck.
Using this logic, the generator to run refrigerator and freezer can be categorized in to three size groups.
- 1,500W generators – For all mini-fridges and most Energy Star-rated refrigerators and freezers.
- 3,000W generators – For all standard refrigerators and freezers, the 3,000W generator is the most common generator used to power a refrigerator.
- 5,000W+ generators – It’s used to power all very big refrigerators and freezers. Not many people have such a big refrigerator.

Generator for Refrigerator – FAQs
Is it safe to run a refrigerator on a generator?
If a generator is unable to produce the appropriate quantity of power, it may cause damage to your refrigerator. If your refrigerator doesn’t get enough power, it might damage the compressor, expansion valve, and other components. When a household appliance is turned on, it consumes 3-4 times the amount of energy it consumes when it is turned off. If the running wattage is 800, the starting wattage will be 3,200.
Overloading a generator might damage your appliances to break down. Running appliances and electronics equipment that aren’t in use might lead them to burn out.
How to power your refrigerator with generator?
Connect a fridge to a generator by checking the power requirements. A typical generator can deliver 20 amps, or maybe 30 amps, or even more. Most one-door fridge is rated 6.5 amp compressor and a voltage of 110 to 127 volts. The full load power (amps * volts) required for operation of the fridge is 6.5 amps x 110 volts = 715 watts. The startup surge wattage is 7153= 2145 watts. Make sure that all of your equipment, when added together, does not exceed the wattage rating of the generator.
How to Connect Your Generator to Fridge?
- Move the portable generator to a flat spot in the yard or in the balcony if you are living in an apartment.
- If you are using battery operated indoor generator then it’s fine if you place it the kitchen beside the fridge.
- Plug the pronged end of the 16 or 14 gauge extension cord into the generator’s power outlet.
- To reach the fridge, run the extension cord from the generator into the structure through a doorway or hole.
- Start the generator and let it run for a few seconds to get to the operating speed.
- Remove the fridge from the power cord and plug it into power outlet of the extension cord.
- Make sure that the fridge works properly and is running correctly.
What About Freezers?
When it comes to freezers, intermittent power is important because they are more efficient at retaining heat and you are not likely to be accessing it as much. It can take up to 48 hours or more for the internal temperature to rise above freezing if you have a full freezer.
What’s the difference between running watts and surge watts?
The term “starting” or “surge” is one of the two terms you often encounter. All devices require a certain number of watts to run continuously and some require an additional number of watts to start or to cycle on. It’s not expected that a generator will run continuously above its rated running watt. It should be expected to run continuously at or below the level.
Do you need inverter generator to power your refrigerator?
Clean sine current is required for sensitive electronics such as laptop computers and home audio systems to work correctly. As a consequence, the only safe option to power them is using inverter generators.
Refrigerators, on the other contrary, are a different kind of appliance. A refrigerator or freezer isn’t regarded as a sensitive appliance. They may be safely operated with either an open frame generator or an indoor battery powered generator.
But if it has sensitive electronics as with the case with most modern refrigerator, you are better off with inverter generators.
What are the wattage requirements of an average refrigerators?
The manufacturer’s nameplate, which is commonly placed below the door or on the back of the refrigerator, contains electric demand data for most refrigerators.
A refrigerator uses about 800-1200 watts of power on average; however, this might vary depending on the size of the refrigerator.
When in use, an average 21-cubic-foot refrigerator-freezer consumes roughly 780 watts. You can calculate how much it costs to run your refrigerator once you know how much wattage it requires.
How long to run a generator to keep refrigerator cold?
For four hours of refrigeration, run a generator for one hour. This is a broad rule since many factors influence how rapidly a fridge’s temperature changes and how much power it takes to cool it down.
Will a tailgator generator run a refrigerator?
Yes, If it has enough surge power 3-4 time as the running watts of the refrigerator.
Does a window unit air conditioning use more wattage than a refrigerator?
The functions of a window air conditioner and a refrigerator are similar. Both remove heat from a room and spread it into a large open area. A window unit is a device that extracts heat from a room and distributes it outside. The heat from a freezer box is absorbed by the refrigerator and dispersed around the room. A closed-loop refrigeration system with two coils, a compressor, and a blower fan is used in both. In both, the compressor is the key component that uses electricity.
The compressor pressurizes the refrigerant in a closed-loop system, causing it to condense and release heat in the condenser coil. The capacity of a refrigerator is measured in ounces. A window air conditioner, on the other hand, can have a refrigerant capacity of up to 3 pounds, necessitating a larger compressor that consumes more electricity than a refrigerator.
Generator to Run a Fridge – Other Things to Consider
To obtain a better sense of what size and type of generator to acquire for your fridge, start by answering the following questions:
What is the required amperage for your refrigerator? Usually, each generator includes a variety of outlets that provide 15 or 20 amps.
Is there a freezer built in? If your refrigerator also has a freezer, it will need more energy to run than a refrigerator that simply has a refrigerator.
What is the overall capacity of your refrigerator? If your fridge is smaller, it will use less power to run correctly. On the other hand, if you have a large fridge stocked with goods and food, your power consumption would be higher.
Is there an ice machine and dispenser included? Any additional functions and capabilities that your fridge provides usually come at a higher price in terms of power consumption.
Is your refrigerator equipped with a smart control panel as well as a variety of sensors? If you answered yes, you’ll need to invest in inverter generators, as standard portable generators have a significant total harmonic distortion, which might damage your refrigerator.
Do you have an older or modern refrigerator? Older refrigerators use more energy than newer models. Also, when an electric appliance ages, its power consumption may increase.
Will you have other appliances running at the same time? Initially, many purchase generators just to power their refrigerators in order to avoid food spoiling.
It’s clear that a lot of things come into play when you choose the best generator for fridge.
