Buyer’s Guide

Single vs. Dual Fuel

One of the most important things to decide is the type of fuel. Either you can buy a single fuel or dual fuel generator. This decision will have repercussions in the long run. So, it is better to take your time, analyze your usage pattern and then decide. The main benefit of having a dual fuel generator is that it gives you the freedom to run your generator on two different fuel types. When one is not available, the other can come to your rescue. 75000-watt dual fuel generators usually come with propane and gasoline as the running fuels. Comparing both of them reveals that gasoline has a higher energy rating than propane. It is readily available throughout the year, but its availability comes into question during infrastructural problems or natural disasters. Its exhaust is less clean than propane.

On the other hand, propane is cheaper than gas, burns cleaner but cannot match the power output provided by gas. Propane has the upper hand on gasoline when it comes to shelf life. It can be stored for 8-10 years without any worries, while gas can go bad in just 8-10 months.

Engine Power

The more powerful the engine in the generator, the more stable the output will be. The engine is the like heart of the generator. The power production capacity of the unit depends on it. Therefore, you must select the generator with the best engine.

Peak and Rated Watts

Peak wattage is also known as starting watts, and rated wattage is the other running watts. When looking for a generator, make sure that none of your appliances has a starting wattage more than the generator’s peak output. Similarly, the combined running watts of all the appliances must be lower than the generator’s rated output. If you plan to run 3 machines on a 7500-watt generator with a total starting wattage of 9000 watts and running wattage of 5500 watts, you will need to do some load management. You can deal with such situations by adding the machines one by one to the generator. Please keep in mind that the generator should never be overloaded.

Control Panel

A control panel allows you to manage your generator easily. The latest models come with features like odometer, fuel and oil gauges, on/off buttons, fuel select switch, a choke, indication lights for low oil and fuel, and power outlets. Generators with advanced control panels are a bit costly than the basic units.

Power Outlets

If you plan to use a 7500-watt generator for your home, you will be connecting it with the main electric panel of your home. Power outlets won’t matter in such a situation. For worksites, RVs, and outdoor use, outlets are very important. You will need to run machines directly on the generator, therefore look for all the needed outlets. Your generator must have AC/DC outlets and 120V to 240V converter outlets for heavy machines.

Fuel Tank Size and Runtime

All 7500-watt generators come with a big fuel tank. If you want to run your generator for longer periods without refilling, again and again, look for a generator with a large tank. For regular users, a large tank is more appropriate. If you plan to use your generator for commercial purposes, a big tank will give you more working time in one go. If you are an occasional user, a smaller gas tank will also suffice.

Runtime depends on the size of the tank and the load applied to the generator. Generators with large gas tanks provide more runtime. To get the maximum fuel average from your generator, keep the load applied below 50% of the generator’s total rated power.


7500-watt generators are heavier and difficult to move around. Hence, checking the portability features is very important. It would be best to look for big wheels with a high weight rating and drag handles. A lifting hook is a plus as it helps in placing your generator from one floor to another. If you plan to use your generator at a worksite, you may need it to move it from one place to another; therefore, it must have big wheels and ergonomic handles. The never-flat tires are like a cherry on the top.

Safety Features

A generator must have all the safety features like surge voltage protection, protection from overloading, overheating, and auto shutdown in low oil. Such features keep your appliances and the unit safe from operational problems and enhance the generator’s life.

Operational Sound

The larger the generator, the more noise it will produce. Therefore, the importance of checking the sound rating increases while buying a larger generator. Some local authorities don’t allow the use of generators above 75 DB sound levels. Hence, you must check the local laws and generator noise rating as well.

Starting Mechanism

If you don’t feel comfortable pulling the starting rope every time the power goes out, look for an electric start generator. The starting mechanism doesn’t affect the machine’s operational efficiency but makes it easier to start and more user-friendly. Please keep in mind that electric start models are a bit costly than recoil start units.


One of the most important things which will help you maintain your generator in a mint condition is the warranty. When you have a generator with a warranty, you don’t need to worry about repairs during the warranty period. The industry standard for generator warranty is 1-3 years. Make sure you read all the terms and conditions related to the warranty agreement.


The last but one of the most important things to consider is the price. If you want all the latest features in your generator, get ready to pay more. We suggest that you look for the latest model with the best features because you don’t buy a generator every 1-2 years.


What devices can a 7500-watt generator run?

The simple rule in deciding what devices a generator can run is to check its starting wattage and then compare it with the generator’s peak power. In this case, any device having a starting wattage less than 7500 watts can be powered with a 7500-watt generator. Overall, a 7500-watt generator can run almost all the appliances in your home, such as AC, refrigerator, freezer, microwave oven, electric stove, furnace, water heater, well pump, TV, lights, and a lot of other appliances. It may not power them all at one time, but with some load management, you can run most of the appliances in your home.  It can power construction tools, carpenter’ machines, appliances with a heavy motor such as air compressors for work.

Can I treat a 7500-watt generator as a whole-house unit?

If you live in a small home with 2-3 family members and your home’s total wattage needs are less than 7500 watts, yes, it can be used as a whole house generator. You may need to do some load management, but you can get the work done. If you are connecting a generator to your home, make sure you use a transfer switch.

Is it possible to power an RV with a 7500-watt generator?

Yes. The only pre-requisite is that your generator must be RV-ready. 7500 watts is a lot of power. It can run all your appliances in a medium to big-size RV and trailer.

What are the safety protocols and maintenance needs of a 7500-watt generator?

Safety Protocols

  • Never overload your generator.
  • Ensure ample space for exhaust and heat exchange.
  • Always use fresh gas and never refuel when the generator is running or hot.
  • Maintain a distance of at least 15 feet while running your generator and run it on a flat surface.
  • Use a transfer switch for connecting the generator with your home, or use high-quality extension cables for running appliances directly.

Maintenance Needs

  • Change oil and spark plugs timely.
  • Inspect battery and other components.
  • Never run your generator in rain or snow without a canopy.
  • Always store your generator with an empty gas tank, covered with a generator cover and at a dry place.

Which are the quietest and loudest 7500-watt generators?

Westinghouse WGen 7500 is the quietest (operates at 73 DB), and Sportsman GEN7500DF is the loudest on our list. It operates at 80 DB.

Are there any limitations of a 7500-watt generator?

A 7500-watt generator is heavy, difficult to move around, and has limited power output. You cannot compare it with standby generators, which come with way more power than 7500 watts and offer auto-start and shutdown features.


7500-watts generators, if used intelligently, can help you luxuriously navigate a power outage. You wouldn’t need to turn off any appliances needed to get your life going during emergencies. Select one from the list above and ride the next power outage without any worries.
