Appliances a 7500 Watt Generator Can Run 

Here are some appliances in different fields that a 7500 watt can power. You must note that these are mostly estimated wattage. You should check for yourself the actual wattage of an electronic to ensure the generator can power it sufficiently.

  1. TV
  2. Small window AC unit
  3. Washing machine
  4. Coffee maker

Can A 7500 Watt Generator Power Many Appliances Simultaneously? 

Simply put yes it can. But there are conditions. First of you need to ensure that the appliances running watts when all added would not be more than 7500 watt. 

This is a rough estimate on how to safely run your electronics.

Basic appliances like the microwave use a measly 100 running watts, PC consumes 300 watts on average, washing machine 2000 starting watts and 1200 runnings watts. All of the appliances mentioned, the sum of all the watts is about 1600 watts. You can even add central air, fan, and fridge into the mix and the generator won’t budge.

So to answer your question, a 7500-watt generator is more than capable to run multiple electronics. However, this all depends on the power of the unit.

During a blackout, you have to prioritize essentials appliances that need to be powered. Since you can’t run heavy appliances all at once, you need to implore caution and pragmatism.

Running power-sucking appliances like a Furnace fan blower requires 800 running watts and 2350 starting watts, a sump pump requires about 1050 starting watts and 2200 running watts, and an electric water heater would require 4500 running watts.

Now when you add the running watts required to power all these electronics, you will find out it’s a bit overwhelming.

 In that case, you should cut down on some of the appliances to ensure the generator operates at its optimal level.

 You can take turns to power some select equipment after which you can power another set when you are through with the first set

What are the best 7500 watt generators?     

There are many offerings from Champion generators, Westinghouse, Honda, Pramac, Duromax, and other reputable brands. 

I have taken it upon myself to mention some of the best generators around the 7500-watt range. These units have strong positive reviews by first-hand users, you can’t go wrong with any of the options.

What Is Starting and Running Watts?

You must have been tired of reading about it. But it’s the most important factor to consider to size a generator that’s suited to your needs.

The Starting watts also known as surge power is the watts a generator can put out to power appliances. In most cases, the surge watt is important for larger appliances like the refrigerator, washing machine, electric oven etc.

The running watt known as continuous watts is the power that is constantly maintained by the generator when it’s running. The startup watt when all added must be less than the running watts. This step is to avoid adding excessive load on the generator that might break or wear down the generator.
