Best 8000 8500 Watt Generator Buying Guide 2023

Are you still confused and hesitant? You do not know what you should choose?

Do not need to be baffled. We are here to help you out. Check out our impressive buying guide. It will guide you in a better way about the best 8000 8500-watt generators. Let’s get started.


Running Hours

Do you face a lot of power outages in your town? Yes?.  If you are going through such circumstances, choose a generator that gives you good running time. Sometimes,  power shortages last more than 24 hours. In this case, select a generator that gives maximum running time.


Generator Material

Here is another pro tip; check the material of a generator. We recommend you go with stainless steel and heavy-duty generator material. Make sure to have a strong sleeve; it will protect your equipment and extend its lifespan.

Usually, generators last longer. So, there is no reason to go with a cheap material generator. Cheap material generators won’t perform well and third-class material affects the durability of a generator.



A Fuel tank is a crucial aspect that you must check before making a purchase. Always check the fuel capacity of a generator. Go with a large fuel tank generator as it can run longer.

However,  fuel type should not be ignored too. Mostly,  generators come with propane and gasoline fuel options. Choose a fuel type that is easily accessible in your town. Besides this, we recommend you buy a dual-fuel generator because it gives a freedom of choice.



There are two types of power. The first is running power and the second is starting power. Running power is a stable power; however, starting is when the machine begins operating.

You should also check the starting and running power of the generator and make sure that a specific generator can power your required appliances. Always buy a higher-wattage generator than your power needs.



The most common engine type is the 4-stroke OHV engine. The engine efficiency depends on its HP. The high HP engine is preferable to use. The average HP is 15HP. But it is recommended to go with a higher HP engine than the average HP.

Make sure that the generator engine has air-cooled features. This feature protects the engine from overheating.

There are 4-stroke and 2-stroke engines. But a 4-stroke engine is more efficient than a 2-stroke.


Noise level

Do not go with high dBa generators as those are way noisier and can irritate you. That generator could not be suitable for the surroundings as well. 76 dBA is a good noise level for an 8000-watt generator.


Security Features

Safety comes first. Check these safety features in a generator. First of all, the low oil shut-off feature helps you to avoid checking the oil of the generator repeatedly. The generator will be shut off automatically. It prevents the generator from any damage.

Automatic voltage regulators and co-detection are other useful safety features that must be in a generator.


Electric Start

That time has gone when people used to start generators manually. Now, most generators offer an electric start feature to quickly run the generator in time of need. Consider such an electric start generator.


Digital Meter

A Digital meter is a most useful feature. It helps you to check the running hours and fuel level. Through a digital meter, you can keep yourself updated about the generator.



Generally, generators come with a 1-3 year warranty period. However, some generators do not come with a warranty period. But we advise you to always go with a generator that comes with a 2-3 years warranty period.



The generator comes in different price ranges. Some are less expensive and some are highly costly generators. We made three categories of price.



Inexpensive generators are cheap and come with fewer features. They are not high-performing generators. You can buy such generators for under $900.


Mid Range

Mid-range generators are comparatively better than inexpensive ones. They offer the best features and have powerful engines. Their running time is also the best. You can buy such a generator from $900 to $1100.



Expensive generators have a price tag above $1100. In this price range, you could buy the best portable generator. Such generators are high performing and provide a good warranty period.



Can an 8000-watt generator run the whole house?

The short answer is yes.  An 8000-watt generator can easily bear your whole house load.


What is the running time of an 8000-watt generator?

An 8000-watt generator provides more than 5-16 hours of running time. Running time depends on the load and fuel tank.


What will be the cost of an 8000-watt generator?

The cost of an 8000-watt generator depends on the brand. If you want a good quality generator,  it will cost $1000. However, you can find a cheaper option in the market.


How long can an 8000-watt generator run on propane?

You can run a generator for more than 5 hours on propane gas. But if you face a longer power shortage, you can switch to the gasoline fuel type.



It has always been difficult to select a generator. Because there are a lot of technicalities that you will have to face. You must be aware of the running time, noise level, engine, and other features and specifications of a generator. You need to spend time conducting research and reach a final decision.

But we make this daunting task easy for you. We selected the top-rated 10 best 8000 8500 generators after conducting sufficient research. Our team tested these generators personally. Now,  we are confident that these 8000 8500 watts generators can easily fulfill your power needs and won’t let you down.

Our buying guide is the cherry on top and gives you some extra knowledge regarding generators. We hope that now you have a sufficient understanding regarding generators and can confidently pick one.
