Generators with 8000 peak watts or more are powerful but you still want to choose one of the best options for reliability and convenience.

Best 8000 watt generators top picks

Before going into a few examples it is important to note that the market for 8000 peak watt generators is not that good.

Because of that, I also implemented some top picks with slightly more peak watts. This makes it so you still have quality generators to choose from.

  1. Champion 100520 8750 – Best “8000 watt” generator (8750 peak watt inverter)
  2. RYOBI RY906500VNM (8125 peak watt non-inverter)
  3. Predator 8750 (8750 peak watt inverter)
  4. WEN DF875iX – Best dual fuel “8000 watt” generator (8750 peak watt inverter)
  5. Firman P06701 (8350 peak watt non-inverter)

Keep in mind that I still gave bonus points to generators with starting watt amounts closer to 8000.

If you don’t mind investing a bit more, certain stronger generators may be more to your liking.

5 Best 8000 watt generators reviewed in detail

People who are in a hurry can use the list of top picks to quickly choose a generator.

However, the more detailed reviews of all the top picks for the best 8000 watt generators can help you make sure you are choosing the right model.

1. Champion 100520 8750 – Best “8000 watt” generator (8750 peak watts)

Our top pick for the best “8000 watt” generator is the Champion 100520 8750 which actually has 8750 peak watts and 7000 running watts.

Even after considering the generators closer to 8000 starting watts, I concluded you will likely prefer this option due to the combination of quality, reliability, and reasonable price.

Champion 100520 8750

This Champion 100520 8750 still requires somewhat of a higher investment but with the customer review positivity differences, it seems this will be worth it in the long term.

One thing you want to keep in mind is that the run time is somewhat “lower” with 10.5 hours at 25% load.

Pros

  • Champion 100520 8750 offers 8750 starting watts, 7000 running watts, 30 amps, and 240 volts.
  • Reasonable noise levels of 72 dBA
  • Less than 3% THD
  • Electric start
  • Four GFCI outlets
  • Weight of 155.4 lb (70.5 kg)
  • Relatively positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties
  • A lot of customers

Cons

  • Somewhat shorter run time of 10.5 hours at 25% load
  • Some customers find the generator a bit loud
  • Slightly pricier than generators closer to 8000 peak watts

This is still a nice run time but you will have to interrupt your camping fun, tailgating party, food truck service, etc. just a bit more often to refuel compared to other portable 8000 watt generators.

Some customers also find the 72 dBA of the Champion 100520 8750 a bit loud.

However, this noise level is actually relatively low for this power category so you will not find many quieter 8000 watt generators.

In short, it is true that the Champion 100520 8750 is slightly more powerful and pricier.

However, because of the suboptimal quality and reliability of alternatives, you will likely prefer this option over other models in this list of the best 8000 watt generators.

Especially for something like backup power.

2. RYOBI RY906500VNM (8125 peak watt non-inverter)

The RYOBI RY906500VNM is a 8125 peak watt model which gives it bonus points for this list of 8000 watt generators and makes it more budget-friendly.

An important thing to note first is that the RYOBI RY906500VNM is not an inverter generator. In simpler words that means its high THD power is not suited for running sensitive devices.

Even in the case of medium-sized devices, the high THD power can speed up wear and tear.

That aside, it is possible that you have your own inverter, don’t mind the risk of faster wear and tear, and/or plan to power machines where this matters less.

Pros

  • RYOBI RY906500VNM offers 8125 starting watts, 6500 running watts, 30 amps, and 240 volts
  • Reasonable noise levels of 72 dBA
  • Good run time of 10 hours at 50% load
  • Weight of 195 lb (88.5 kg)
  • Four GFCI outlets
  • CO sensor
  • 3 years limited residential and 90 days limited commercial warranties
  • A lot of customers
  • Budget-friendly

Cons

  • High THD power is not suited for running sensitive electronics
  • Relatively short commercial warranty
  • Decent number of technical issues

In that case, the RYOBI RY906500VNM can be a relatively budget-friendly, relatively quiet, and reasonably good 8125 watt generator.

One other detail to keep in mind besides the high THD is that there are a decent number of reviews where customers have technical issues with this generator relatively fast.

It seems RYOBI does a decent job helping people if they are still within the warranties but things like this would take up extra time and effort which is not ideal.

The RYOBI RY906500VNM has its advantages and disadvantages. Whether it is worth it depends on your personal preferences and needs.

3. Predator 8750 (8750 peak watt inverter)

The Predator 8750 is a good generator with as the name implies slightly more than 8000 peak watts for people who don’t need the most reliable standby generator for home backup power.

Instead, the somewhat suboptimal brand reliability reputation of Predator generators tends to be more suited for camping, running certain power tools, and similar situations.

At least if you don’t mind the 75 dBA which is somewhat expected at this power level but can sound loud anyway.

These more suboptimal details need to be mentioned but you also want to know that the Predator 8750 is actually a good generator for the money.

Pros

  • Predator 8750 offers 8750 starting watts, 7000 running watts, 30 amps, and 240 volts
  • Good run time of 15.1 hours at 25% load
  • “Clean THD energy”
  • Electric start
  • Weight of 151 lb (68.5 kg)
  • Four GFCI outlets
  • CO sensor
  • 2 years limited emissions control system and 90 days limited product warranties
  • A lot of customers
  • Budget-friendly price for a powerful inverter

Cons

  • Short warranties
  • Decent number of people find the noise levels of 75 dBA too loud
  • Some people find the included manual lacking

Especially the low investment required for a portable inverter generator with 8750 starting watts and 7000 running watts is impressive.

Additionally, the long Predator 8750 run time of 15.1 hours at 25% load allows you to enjoy your clean THD power without too many refueling sessions.

In short, the Predator 8750 may not be the option with the best reputation for reliability on this list of 8000 watt generators.

However, its budget-friendly price and good features could still be worth the investment. Potentially with an extra warranty plan.

4. WEN DF875iX – Best dual fuel “8000 watt” generator (8750 peak watt inverter)

The first thing that stands out in the WEN DF875iX in this list of the best 8000 watt generators is its dual fuel feature that allows you to run on gasoline and propane.

Some people just prefer running on propane but just having the flexibility can be helpful for unexpected power outages or off-grid living.

WEN DF875iX

The electric start and CO sensor of the WEN DF875iX are not unique but nice additions anyway.

One main downside to note is that the WEN DF875iX does not have that many customers yet at the time of writing.

Pros

  • WEN DF875iX offers 8750 starting watts, 7000 running watts, 30 amps, and 240 volts (gasoline)
  • Dual fuel feature allows you to run on propane too
  • Run time of 6.7 hours at 50% load
  • Less than 1.5% THD
  • Electric start
  • Weight of 140 lb (63.5 kg)
  • CO sensor
  • Relatively positive customer reviews
  • 2 years limited residential and 90 days limited commercial warranties

Cons

  • No noise level rating
  • Relatively short commercial warranty
  • Not a lot of customers yet

There are generators that look good on paper but don’t offer the best customer experience due to technical issues.

That being said, while there are slightly better brands too, WEN generators tend to be solid so you can expect something similar from the DF875iX.

The WEN DF875iX also gets bonus points for being one of the few portable dual fuel inverter generators with more than 8000 starting watts.

This generator will not be for everyone but if you like the dual fuel feature, you can definitely consider this model.

5. Firman P06701 (8350 peak watt non-inverter)

Two things to note first about the Firman P06701 are that it is a non-inverter generator and that this specific model does not have that many customers yet.

If you want to run sensitive electronics you will need your own inverter or need to choose one of the other models on this list of good 8000+ peak watt generators.

Additionally, the 81 dB at 75% load is relatively loud which makes this generator not so good for camping with a lot of people close to you or home backup power in a small neighborhood.

However, if you are one of the individuals that does not mind these things too much, the Firman P06701 can be a solid generator for the money.

Pros

  • Firman P06701 offers 8350 starting watts, 6700 running watts, 30 amps, and 240 volts
  • Great run time of 11.5 hours at 50% load
  • Weight of 212 lb (96.2 kg)
  • 3 years limited warranty
  • Budget-friendly

Cons

  • Relatively loud with 81 dB at 75% load
  • Not a lot of customers yet

The low number of reviews is not ideal but Firman tends to be a good generator brand that makes its customers relatively happy.

And in case something does go wrong you have the 3 years limited warranty to fall back on.

In short, if you want a non-inverter generator with more promising reliability than the RYOBI RY906500VNM at a lower price and don’t mind the extra noise, the Firman P06701 can be for you.
