Buying Guide

8000-Watt generators can act as an urgent power alternative in houses or as primary supply of electricity for example on any construction site and on the camping trip or in the RV.

The history of generators goes far away. Nowadays, with such an extensive range of choices in terms of these convenient engines, discovering the ideal generator for the specific budget and needs is not a simple task.

Listed below are the important things which will assist you in selecting the ideal portable 8000-Watt generator for home, or even off-grid power requirements.

Power requirements

Where and how you plan to use the portable generator decides the power ratings of generator which you ought to get. The requirement of power in a house differs from the requirements of power in a campsite or on construction site as well as for each one of these circumstances; you will require generators of various ratings.

The power amount which you require is influenced mostly by the things that you will power up. Home appliances are typically rated in the running and starting wattage. Starting watt is the power amount needed to start an appliance up, and consumption of power is typically higher at this stage.

Running watts, on the other hand, are the power amount required to run appliance constantly. The rating of starting wattage is many times bigger than running wattage. Not to mention, this can deceive you on power amount which you need from the portable generator.

Most models on our list features 8000 running watts, which is quite enough for powering 2 large appliances or several smaller ones.

Best 8000-Watt Generators


Generators which run on the fossil fuels tend to be the biggest causes in terms of emissions. It includes gasoline and diesel generators.

If you’re trying to find a green portable generator than solar power generator or all those which run on the propane can be perfect for you. However, they won’t likely to be as powerful as gas ones.

In any case, try to find the exhaust accreditation which the generator might obtain, for example, CARB, CSA or EPA.

Number of The Outlets

Needless to say, a model having a number of outlets lets you use the generator optimally by spreading the load. But, using all outlets is simply not recommended because it strains your generator, and it puts its durability in jeopardy.
We suggest using all outlets just in the emergency circumstances, or when the appliances which you’re using are actually low-wattage.

Green-Power America GPG8000EW 

Easy Movement

The weight of generator is not necessarily, but usually linked with the power amount it produces. More powerful generators tend to be somewhat heavier. The existence of handles and wheels makes it simpler to move all these gensets around.
Specialized generators are somewhat heavier as they “pack-up” more parts and a bigger fuel tank so that you can generate the power which you want for your different power equipment and tools.


The top-rated generator which you can select needs to be simple to use as well as features automated control options which protect your generator from deterioration. For instance, look for low-oil “shut-off” feature that turns off the engine while the oil level gets very low.

An electrical start is one more of such functions; with an electrical ignition, you just push a switch to start up the engine. On the other hand, the “pull-cord” approach to start generators while being tiring and outdated, is still a necessary backup option.

DuroMax XP8500E -4

Fuel Tank Run Time

Generators typically indicate their run-time at possibly half (50 percent) or quarter (25 percent) of load. It signifies how long this will work on a full-tank of the fuel at fixed percentage of the total power.

However, if you plan to use your generator for the emergencies, and also you can’t estimate just how long your main supply of power is going to be out, you should obtain a generator having a bigger fuel tank.

Fuel Efficiency

Efficient consumption of fuel is an element of a great portable generator. These kinds of generators, adjust the level of consumed fuel along with applied load.
So, with such setting, engine operates in the full-throttle just when the “applied-load” equals the maximum rating of generator. This efficient consumption of fuel allows you to save bucks on the fuel expenditure.

Noise Pollution

The generators which run very noisily can trigger hearing damage as well as act as an annoyance to your friends and neighbours. To avoid this, you should purchase a convenient generator which runs as silently as possible, and/or buy extended cables so that you can set the generator just a few feet away.

The tolerable level of noise for the generators is around 70 db and less. If it’s not or just a bit louder, then it is easy to hold a discussion comfortably standing nearby.
However, the generators intended for factories are usually a bit louder due to their higher power rating. Experts using these units recommend to buy extended cables in addition to the right safety gear to protect their well-being and health that influence noise level as well.

Generac 6954 -1


Generators from the established brands, for example, Yamaha and Honda are somehow expensive, but for an excellent reason.

All these manufacturers are highly experienced in creating these generators, and also you can easily be certain that their particular generators are trustworthy enough to last for a long time.

Customer Service and Warranty

Generators are expensive machines that can cost you a few thousand dollars in case they get ruined. It’s for this sake that you must only purchase a generator which is supported by an extensive warranty from manufacturer. This way, it is easy to get your generator fixed, or even replaced in case of a failure.

At the same time, an extended warranty shows the trust of manufacturers in their item. A great warranty is 2, or 3 years long.

Go through the warranty info carefully to understand what is actually protected and what is not.

Safety Tips for Your 8000-Watt Generator

These units can be hazardous if they’re not operated with care. Listed below are a few significant safety tips while using them:

  • Do not pour gas in the hot generator. Additionally, you don’t need to change the tanks on “LP-gas” generator while it is still hot.
  • Do not run any unit unless it is on the level ground. The generators positioned on angle can leak gas as well as turn out to be a fire risk.
  • Do not make electric connections to the generator when it is running. Ensure that all the cords are “plugged-in” and also connections made just before starting this up.
  • Make sure to inspect the generator regularly. Check for accumulating dust, damage and other problems which can hinder the performance or result in a safety problem. If you find some issues with the unit, then take your generator to a professional to be serviced properly.
  • Don’t make an effort to move weighty units yourself. It is because you can harm your back seriously or injure the muscle. It is safer to call your friend to assist simply to be risk-free.
