🥇 List of Electric Appliances & Wattage Usage Chart (2021 UPDATE) (2025)

Are you looking for wattage requirements for various electric appliances to calculate the power needs of your generator? Then look no further as we have the most extensive list of RV, camping, and household appliances ever created.

Our team here at Generatorist has helped over 350,000 visitors find information about generators and we will help you as well. Just keep in mind that these are just rough estimates and to learn the actual numbers, you need to check info-tag on your specific products.

Our data is gathered from reputable government websites, popular generator manufacturers likeHonda,GeneracorYamahaand merchants likeLowe’s,SearsorHome Depot. We add new appliances and update the numbers on a regular basis to make this the most comprehensive resource out there.

If you want to learnwhat electronic appliances will your generator run, you need to get ready to do some math. Don’t worry, it will be a very simple process of adding up several numbers.

To determine what appliances you can run on this type of generator at the same time, you need to follow these steps:

1. List all electronic appliances in your home you want to keep running in the case you are out of power (here is agreat list full of appliancesyou might use)
2. Write information from their name tags on required running and starting watts into a table (see examples below)
3. Then you need to add up all the running watts required to operate your appliances
4. The next step is to find the item with the highest additional starting watts
5. Then add this number to your total running watts
6. The final number represents the amount of starting watts your generator needs to provide

Here is a good example of calculatingwattage needs for a 4000 watt generator.

We have decided that in case of a weather-caused blackout,wewould need only essentials such as refrigeratorwith a freezer so our food will be safe, a lamp that will serve as an emergency light source, a small window AC unit to keep the temperature under control, a toaster, and a laptop.

As you can see in our example above, if we add up all running watts of our appliances we get the number 2,950 – so we are well within the 4,000 running watts limit (850 + 700 + 50 + 150 + 1,200 = 2,950).

However, we would need a generator that is capable of producing at least 6,550 surge (starting) watts to power all these appliances (2,950 + 3,600 = 6,550).

Just keep in mind that some electric appliances in your home may not have running watts provided on their data tags. If this is the case, you can estimate the running watts required thanks to the following formula:

So, as long as you have required Volts and Amps, you can easily convert them into an estimate of required running watts. Maybe you remember that this equation represents the Ohm’s lawfrom High School physics.

Luckily, there is a device called “appliance load tester” that you can get to determine howmany watts each your appliance takes. You can easily get one from Amazon and avoid all that physic´s equation.

You need to check each appliance / power tool in your home individually to see the precise wattage requirements. Feel free to check out the wattage requirements of the most popular household appliances,, or power tools for contractorshere on Generatorist.
