What Will a 10000 Watt Generator Run in a House

Truth be told, spending money on an expensive and high-powered generator when you experience a very minimal power outage is a waste of money. But it is risky not to buy any generators either because of natural disasters.

So, what can you do? The easy solution is getting an inexpensive generator that is just enough to keep your home alive when facing unexpected power cuts.

You might be wondering, can a small generator take the load of all the household appliances? Or what will a 10000 watt generator run in the house? Well, you found just the right place to get your answers! 10000-watt generators, in fact, can be very powerful than they appear, so let’s take a look at what you can power with these machines.

Things You Should Know Before Getting a 10000 Watt Generator

Sure, a 10k watt-generator can provide enough power to run multiple appliances, but that does not mean you can grab one and start running it without first calculating your total wattage needs.

One crucial step before choosing a generator is to list all the critical household appliances you wish to run during power outages. Once you have an average estimate of the total watt you want to cover, you can choose the right generator for your entire house.

However, calculating how many watts you need to power is not a piece of cake; you have to consider several crucial factors while adding up your wattage needs. The reason is that all the large appliances’ running and surge wattage are not the same.

For instance, an electric range can require an extra 1000 watts over its running watts while starting. The same goes for central air functioning on a 220-volt circuit. Therefore, you must calculate the running watts and determine how many extra watts your 10KW generator can handle to cover the surge watts.

What Are Surge Watts?

Surge watts, also known as starting watts, are the additional wattage required to start a motor-powered machine. Most critical household appliances like a refrigerator and air conditioners require surge watts. Moreover, a sump pump or well pump is essential equipment that also needs starting wattage to start functioning.

The starting watts usually last for 2-3 seconds. However, even though the amount for starting watts is less, it should not be ignored. You should count the surge watts and make sure that the total wattage of all these appliances does not exceed the capacity of your 10,000-watt generator.

If any appliance draws more energy than the generator can handle, there will be a high risk of overloading. It may damage your generator and, at the same time, all the critical household items connected with it.

Benefits of 10,000-Watt Generators

One of the biggest reasons these generators are popular is their portability and cost. These machines come with easy-to-maneuver handles that allow you to carry them conveniently. Furthermore, it also features heavy-duty wheels enabling users to roll them any place they want without any hassle.

This portable generator can run with fuel, propane, or diesel. That’s not all; you can also find a dual fuel generator and have more than one convenient option to run your machine.

Furthermore, these portable machines also come in handy for outdoor events along with home and construction sites. You can use it on your job site to power demanding electric tools and RV accessories.

Its quality fuel tank can hold enough fuel to cover heavy-duty jobs. However, these portable machines usually do not feature a transfer switch system; you have to turn them on manually.

Types of Appliances You Can Power with 10k Watt Generators

Using this portable generator, you can run several tools, including kitchen appliances, electric tools, lighting circuits, and even clothes washers. So, let’s jot down some of the home equipment along with their wattage rating.

Window Air Conditioner

Generally, a window air conditioner requires 1200-3250 watts to function. However, the units may vary depending on the model. You can easily use an air conditioner or central air with your 10k-watt generator.

Microwave Oven

A microwave oven requires up to 1000 watts to run. But compact models only need 500 to 800 watts to function. Therefore, you can conveniently power these using any generator rated 10000 watts.

Washing Machine

Washing machines come with 500 watts running units. However, the surge watt is 1400 units. So, even though the running rate is low, you should definitely calculate the starting rate while determining how many appliances you can run with your generator. 


There is no doubt that a 10,000-watt generator can operate lights. Lights are undoubtedly the most important thing you would want to use during a power outage. The total watt needed to run a light bulb is usually written on the package it arrives in.
