Determining your
If you want to learn what 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:
- List all electronic appliances in your home you want to keep running in the case you are out of power (here is a great list full of appliances you might use)
- Write information from their name tags on required running and starting watts into a table (see examples below)
- Then you need to add up all the running watts required to operate your appliances
- The next step is to find the item with the highest additional starting watts
- Then add this number to your total running watts
- The final number represents the amount of starting watts your generator needs to provide
Here is a good example of calculating wattage needs for a 4000 watt generator.
We have decided that in case of a weather-caused blackout, we would need only essentials such as refrigerator with 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.
| Selected Appliances | Rated (Running) Watts | Additional Starting Watts |
|---|---|---|
| Toaster | 850 W | 0 W |
| Refrigerator / Freezer | 700 W | 2,200 W |
| Laptop | 50 W | 0 W |
| Lamp (2 Lightbulbs) | 150 W | 0 W |
| Window AC (10,000 BTU) | 1,200 W | 3,600 W |
| TOTAL | 2,950 W | |
| 6,550 W |
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:
Watts (W or kW) = Volts (V) x Amps (A)
Amps (A) = Watts (W or kW) / Volts (V)
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 law from High School physics.
Luckily, there is a device called “appliance load tester” that you can get to determine how many 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, RV & camping appliances, or power tools for contractors here on Generatorist.

Hi. I’m so glad I found your site. (Can’t wait to tell other family). We were a victim of the last bad weather winter storm in Texas, Outage’s and roll outs for hours, it was tough. I don’t want our pipes to burst, and I need and alternate way to keep house warm at least 68 degrees. I have two portable ceramic heaters (1500 watt) I want to run if needed (nothing else). What size inverter generator do I need please? Thanks. Robert
Very helpful, having bought a premium boiling water appliance I wanted to know what amperage was required.
Thank you
Kevin
If my space heater uses 3.74 kwh in 3 hours. how do I figure out the cost of running it for a 24 hr period?
3.74 divided by 3 = 1.246 x 24 = 29.9units / day x whatever your unit cost is.
Hi. I’m moving into a van and will be installing solar power and batteries to live on. Would you be interested in speaking with me in more detail about trying to figure out my power consumption? After reading your article and trying to figure it out I realized that wasn’t my strong suit. So I figured I’d ask the expert first. Thank you for your time.
This has been such a useful website…
Everything in one place.
Really helpful.
Much thanks and appreciation for all this effort.
P.S if the list of appliances and their wattage was made downloadle into a pdf doc it would be really handy.
Kind Regards

I really appreciate your blog post about how to find the wattage usage of a specific electric appliance. I was looking for my electric oven’s wattage requirements and this was really helpful and saved me hours of time.
Hello. I have at home an small electric DREAN WIND cloth dryer from Argentina. New. It works with 220 v only.
May I plug in this appliance into the 220 v (regrigerator and or stove) in Miami? Phases are 50 Hz. 350 W. 2800 RPM.
If not, any suggestions will be appreciated.

I have never known a seed to be planted in the ground to be grown into a magnificence object without
the helping care, skills, and other things of people who encouraged the seed ‘s growth to maturity, is that brotherly and sisterly love, thus, no person is an island in this world, we all need a helping hand, now and
then. Thanks I a lot for the appliances’ wattage rating, my generator stands a good chance to help me tip toe my way through the heat this summer 2023.
