5 Best 8000-Watt Generators Reviewed in Detail (Fall 2022)

What Do I Power with It?

An 8000-watt generator can power a variety of appliances and devices. Typically, it can power up to eight standard household circuits, which is enough to run most refrigerators, lights, and other common appliances. Additionally, it can also provide limited backup power for some larger appliances like air conditioners.

Essential Specifications of a Power Generator

Generator Type

Generators are varied by the types of fuels they use. Generally speaking, the multi-fuel ones are more expensive.

The main difference between the types of generators is the fuel that they use. Gasoline generators are the most common type, but they can be more expensive to operate than propane or natural gas generators. Propane and natural gas generators are less expensive to operate, but they may not be available in all areas. Dual- and tri-fuel generators are generally more expensive than regular ones, but they allow you to switch between fuels, which can be handy at times. If you want your generator to be versatile, read our guide on the best dual-fuel generators.

Peak and Rated Power Output

When shopping for a generator, it’s important to understand the difference between peak and rated outputs.

Peak output is the maximum amount of power that the generator can produce, while rated output is the power that the generator can safely produce over a longer period of time.

For example, let’s say you have a small appliance that requires 1000 watts of power to run. If you only need the appliance for a short period of time, you could choose a generator with a peak output of 8000 watts. However, if you plan to use the appliance for an extended period of time, it’s important to choose a generator with a rated output of 1000 watts.

Tank Fuel Capacity and Runtime

A larger fuel tank will allow the generator to run for a longer period of time without needing to be refilled, while a shorter runtime will mean that the generator will need to be refueled more often.

Materials and Durability

You want to make sure that the materials are durable and will last for a long time. Additionally, you also want to make sure that the casing is made out of steel or another durable material. This will help to protect your investment and keep your generator running for a long time.


5 Best 8000-Watt Generators To Keep Your Home Working! (Fall 2022)

Engine is the key part of a generator – it is responsible for converting fuel into electrical power, supporting all of your appliances.

The engine is the most important part of any power generator. It is responsible for converting energy into electrical power. There are many different types of engines, but all share the same basic principle: they use fuel to create mechanical energy, which is then converted into electricity by a generator.

One of the most popular types of engines used in generators is the OHV engine. Overhead valve (OHV) engines are known for their high power output and reliability. They are typically used in larger generators, such as those that produce 8,000 watts or more of power.

OHV engines are also relatively fuel-efficient, which makes them a good choice for use in portable generators. Portable generators need to be able to run for long periods of time without needing to be refueled, and OHV engines can help make this possible.

Noise Level

Some models are much quieter than others, so if you need a generator that won’t disturb your neighbors or disrupt your work, you’ll want to pay close attention to noise levels. All of the generators in our selection have a noise level around 70 dB, which equals to the volume of a normal conversation. If you are looking for a particularly quiet generator, check our comprehensive guide on the best quiet generators.

Safety Features

When it comes to portable generators, safety is always a top priority. Many generators come with safety features like overload protection and automatic shut-off to help prevent accidents. Be sure to read the product description carefully to see what safety features are included.

Starting System

There are a few different types of starting systems for generators, but the most common is the electric start. This type of system uses an electric motor to turn the generator’s engine over, which then starts the generator. Some generators also have a manual start, which requires you to physically turn the engine over yourself. However, this can be difficult if you’re not familiar with how to do it.

The advantage of an electric start is that it’s much easier to use than a manual start. You don’t have to worry about getting the engine started yourself, and you can simply push a button to get it going. Electric start generators are also usually more reliable than manual start generators.

However, there are some disadvantages to using an electric start. Firstly, they’re usually more expensive than manual start generators. Secondly, if the power goes out, you may not be able to use your generator if the electric start doesn’t work


An outlet is a point on a power generator where electrical current can be taken off to be used. The three main types of outlets are 120 volt and 240 volt. Each has their own benefits and drawbacks that should be considered before making a purchase:

  • 120V: the most common type of outlet found on generators. Generally used for smaller devices such as laptops, cell phone chargers, and small appliances. However, they can also be used for larger items such as TVs and refrigerators if the generator has enough wattage.
  • 240V: typically used for larger devices such as air conditioners, washing machines, and dryers. They supply twice the amount of power as a 120-volt outlet, so they can handle more wattage.

Size and Weight

The weight and size of a power generator is an important consideration, especially if you need to transport it frequently. A generator that’s too large or heavy can be difficult to move, and one that’s too small may not be able to power all of your devices.

Portable generators are typically smaller and lighter than stationary models, making them easier to transport. However, they may not have as much power output as larger models. To take a deeper look into the topic of small generators, read our article about the best portable generators.


The warranty helps you to get a replacement or free servicing of the product in case it breaks down due to any manufacturing defect. When choosing a generator, make sure that it has at least 2 years of warranty so that you can use it without any worries. Based on this factor, generator from our list vary from 2 to 3 years.
