A brand says a lot about a generator even before you look at the specifics. The reputation of a brand is important, absolutely essential, in my humble opinion. We wrote this to help you determine the best 7500 watt generator for your power needs, whether for emergency backup when the lights go out, for the jobsite, a natural disaster or whatever else you need it for. Let’s start with our top 5 generators during this pandemic. It’s 2021 the time of writing this and we’re all holding our breath waiting for the vacccine. In the US alone, over 500,000 people have died from COVID19. It’s heartbreaking. This has been a difficult time for most of us. I’ve personally struggled with the isolation for such an extended period of time. I know, you’re here to find the best 7500W generator — keep reading and you’ll find some great choices. These are all excellent in their own way.
What’s the best 7500 generator for your money in 2021? Well, we’ve already shown you a few models, but there are more. One of the favorites with consumers is the dual-fuel Westinghouse WGEN7500DF) — which we’ve reviewed, but in general, customers absolutely love the value and reliability inherent in these Westinghouse 7500W generators.
The best indicator of a quality generator is what is the average opinion of buying customers. Never listen to the opinion of one; it’s not the gospel, or the consensus —
This Dual-fuel from Westinghouse is the best value as far as 7500 watt generators go. For a little extra money over a standard single fuel generator, you get the ability to use propane, which you can store indefinitely. Gas spoils within a year (with fuel stabilizers), so having a secondary option of using propane will be priceless after a disaster, emergency or a massive power outage.
I recommend a dual fuel because it gives you more options when fuel is scarce. Propane is something you an easily stock up on, especially with a tank in your yard. Less risk and no maintenance. Keep it full and use it when you need it. Gas is a little more challenging, and like milk, gas expires.

What is a Generator?
A generator is a device that is designed to produce electricity. How? A simple way of saying it would be, a generator converts mechanical energy into electrical energy. Simple? No? Well then a little more information will help.
What is mechanical energy?
Every object that is in motion has a certain amount of energy. This is called mechanical energy. It is associated both with position of the object as well as the motion at which it is traveling.
As we dwell into the functioning a generator, you will get a better understanding of how it works.
How does a generator work? — A generator uses the simple principle that a man called Michael Faraday discovered, all the way back in 1831. He called this principle, the ‘Principle of electromagnetic induction’.
Video | Consumer Reports Generator Guide
Sounds complicated? Let’s simplify it.
First things first… Let’s clarify what an electric current really is. The movement or flow of electric charges is called electric current. This is the same current that powers devices in your home.
The next thing we need to understand is what an electric conductor is.
Any device that allows electric charges to flow through it is called an electric conductor. Those devices which do not allow the current to flow through it easily are called bad conductors. Good conductors allow the electric current to move through them easily.

Why is this important? You will understand why in a moment.
Faraday discovered that if you moved an electric conductor (a wire), through a magnetic field electric charges would begin to flow through the wire.
This principle forms the basis on which generators were designed and made. That being said, you will imagine huge magnets and large lengths of wire. Today’s generators however come in relatively compact sizes compared to the initial ones. Each generator has a different size and a different output.
Choosing A Generator Based On Size
Choosing the right sized generator is very important. This is simply because, the generator needs to support your electricity requirements. If your generator is too small, chances are you will be putting a high load of stress on the device. This means that the generator will have potential malfunctions and your entire maintenance costs will also increase.
Aside from this, a wrong sized generator can also adversely affect the devices that it is supplying power to. This means that you will have frequent equipment failures. Inadvertently, your expenditure will also rise.
Before we start talking about how to choose the right size, it is prudent that we understand what are the different ranges of generators that are available in the market.
Examples of how many watts it takes to run electrical devices:
Generators can be broadly divided based on the place where they are used. Residential generators have capacities which range from 5kW to 50kW. Commercial generators on the other hand, are much larger. These have capacities which range from 50kW to over 3 Megawatts.
Many people believe that a small generator will do the job. The reason that people give for this rationale is that they do not use the generator all the time. This is in fact a very popular myth and it is advisable not to follow the same line of thought. Why?
The size of the generator does not depend upon the duration of it’s use. It however depends on how much power the device is required to provide. By under sizing the device, you put undue load on it as well as all the equipment it supplies. In this case remember that having more power is always better than having less power.

What Size Generator do I Need?
If you need to calculate on your own, there are certain things that you must keep in mind.
The first thing that you need to know is your requirements. Another way to phrase this is… How much power do you need your generator to supply? To know this you need to make a list of the following things:
- The items that will be powered by the new generator
- The wattage of each item both at the starting point as well as when the device is on.
- The final calculation of the power required to be supplied in KVA or kW
Most people will wonder how to get the wattage of each item. This information is usually written on a plate on the concerned device. If it isn’t, then check the manual. If by some chance you have misplaced the manual, type the model number on the any search engine on the internet and you will get the required details.
Calculating the wattage required is complicated and time consuming. More importantly, you cannot afford to get your calculations wrong. Use the following interactive wattage calculator (from Westinghouse) to determine the right size generator for your needs. Don’t skip this part!
Let’s take a quick glance at some generators that have gained popularity over the last few years.
Additional Generator Sizing Resources (wattage calculator):
- Briggs & Stratton Generator Guide
- Generac wattage calculator
- Honda Generator Guide
- Yamaha Generator Guide
For full details on generator sizing I recommend reading our comprehensive article entitled: How Big of A Generator Do I Need? This goes into great detail on how to select the right size generator. It truly is important. There’s no sense in spending money on a generator that won’t handle all the electrical devices you plan on powering. Although, we recommend buying a slightly larger generator than you think you need because it’s better to have too much power than not enough.
A 7500 watt generator is an excellent size for most homeowners because it provides more than enough power to run a wide range of home devices.

Overview | Westinghouse WH7500E | 7500 Watt Generator
The Westinghouse WH7500E is designed to be a portable generator. The designers have not cut corners when designing this particular model. The WH7500E has easily made it’s way to the list of the top five portable generators. Let us take a look at why this model is so special.
This model is fitted with a particularly heavy duty engine. It even comes with cast iron cylinder sleeves, forged pistons and connecting rods. Got a little lost in the technical jargon did you? The multitude of words simply meant that the WH7500E has an engine which is durable.
It doesn’t come as surprise when Westinghouse claims that this model generates a lot of electricity. The WH7500E generates around 9000 surge watts and 7500 running watts. This is something that you may want to note down. After all, it is one of the main criteria that you should check before deciding on the model you want to buy.
The WH7500E has an inbuilt voltage control feature. This makes this generator relatively stable compared to others. It also ensures a high quality electrical output which is safe for your devices to use.
This generator boasts of fantastic run-time. Most of the generator models run for eight to ten hours at half load. What does that mean? It means that once you fill the generator up with fuel, it will take the generator eight to ten hours to use half of the fuel in the tank. The WH7500E has a distinct advantage here. It can last for twelve to thirteen hours on half tank.
The reduced usage of fuel means that the WH7500E is both efficient and more environment friendly as compared to other models.
How does the generator start? Many of the older generators require to be hand cranked. This means that you have to spend some time and a considerable amount of effort and energy to get them started. The WH7500E has a distinct advantage here. It has an electric start option which makes it easy and convenient to use.
Another important feature that we look at is the noise level. The WH7500E comes with an oversized noise reduction pulse flo muffler. This helps reduce the sound output to as low as 71 decibels. This is extremely impressive given the fact that it is a many 5000 watt generators are usually much louder.
Though the device is definitely not light, it is surprisingly compact. The measurements of the device are 27 inches in length, 22 inches in height and 20.5 inches in breadth. This will give you a rough idea of how big the WH7500E is. Though the weight makes portability an issue, the device comes with it’s own wheel kit and collapsible wheelbarrow handles.
**If you need a smaller generator (and cheaper), consider the Westinghouse iGen4200 (read our review) generator.

Is a 7500 Generator the Correct Size for You?
The brief overview of the above three different generators helps us understand that though each device has it’s own engine and own mechanism, the end product is always electricity. The devices can be compared with each other based on the amount of electricity that they provide. Some people also like to compare noise levels. Noise levels are important because you don’t want a noisy generator hammering out a tune next to your backdoor.
Choosing a generator may seem difficult. With an expert appraisal of your house and electricity needs, the choices get narrowed down considerably. The rule of thumb is… Less is never the best!
