Powerful generators tend to be louder but these quietest 8000 watt generators do a reasonable job of keeping the decibels down.

Quietest 8000 watt generators top picks

One thing to note before going into the top picks is that there are barely any 8000 peak watt generators on the market and these are somewhat louder.

To give you quiet and quality generators to choose from, I also implemented models from categories with slightly more peak watts.

  1. Champion 100719 8500 – Quietest “8000 watt” generator (61 dBA) (8500 peak watts)
  2. Champion 100520 8750 – Best “8000 watt” generator with reasonable noise levels (72 dBA)
  3. RYOBI RY906500VNM (72 dBA) (8125 peak watts) (non-inverter)
  4. DuroMax XP8500EH – Quietest dual fuel “8000 watt” generator (72 dBA) (8500 peak watts) (non-inverter)
  5. GENMAX GM9000iE (62 dBA) (9000 peak watts)

It is worth mentioning that there are also quality and price differences between these 8000 watt generators.

For example, you may find it worth giving up a few decibels for more reliability.

How we selected our top picks

So while decibel ratings, reviews mentioning noise, and being closer to 8000 peak watts offer a lot of bonus points, I also looked at other details.

A few examples include:

  • Run time, power capacity, outlets, portability, etc.
  • User reviews
  • Anecdotal reviews from experts
  • Price
  • Brand trustability and reputation
  • The performance categories below

5 Quietest 8000 watt generators reviewed

As mentioned, low noise levels are great but likely not the only detail you are interested in.

The in-depth reviews below can help you figure out which of the quietest 8000 watt generators is the best for your personal situation.

1. Champion 100719 8500 – Quietest “8000 watt” generator (61 dBA)

Due to a lack of quiet models with 8000 peak watts, the Champion 100719 8500 gets the top spot on this list of the quietest 8000 watt generators.

Champion 100719 8500

A downside of going for stronger models is that they tend to be somewhat pricier. This especially applies to the Champion 100719 8500.

However, if you don’t mind investing a bit more in a reliable and relatively quiet generator, this model from Champion can be the right choice.

The run time of 14 hours at 25% load is not the actual longest but should be more than enough to enjoy your camping, backup power, or DIY session without too many interruptions for refuel sessions.

Pros

  • Quietest “8000 watt” generator with noise levels of 61 dBA
  • Champion 100719 8500 offers 8500 starting watts, 7000 running watts, 30 amps, and 240 volts
  • Nice run time of 14 hours at 25% load
  • Less than 3% THD
  • Electric start
  • Four GFCI outlets
  • CO sensor
  • Weight of 216.5 lb (98.2 kg)
  • 3 years limited residential and 270 days limited commercial warranties

Cons

  • Pricier than most of the other quietest 8000 watt generators
  • Not that many customers at the time of writing
  • Fuel fill is inconvenient

The electric start, GFCI outlets, and CO sensors also make it easier to get started with these activities and operate your generator in a safe way.

You do want to know that this specific model does not have that many customers yet. However, Champion generators tend to be reliable.

One thing that is already clear is that the Champion 100719 8500 has a relatively inconvenient refill.

There are ways around this but this downside could make you prefer one of the other quietest 8000 watt generators that is more convenient in this area.

In short, while the Champion 100719 8500 is not perfect and somewhat pricey, you can definitely say it is quiet for this power level.

2. Champion 100520 8750 – Best “8000 watt” generator with ok noise (72 dBA)

The Champion 100520 8750 is not just the top pick for the best 8000 watt generator.

Champion 100520 8750

72 dBA is still somewhat loud and not as impressive as the previous generator but still relatively quiet for this power level.

On top of that, the Champion 100520 8750 has an attractive combination of reliability, solid features, and a reasonable price.

For example, the electric start, GFCI outlets, and clean THD power are definitely not unique but they do make your RV camping, home backup power, and/or tailgating more convenient.

Pros

  • Reasonable noise levels of 72 dBA
  • Champion 100520 8750 offers 8750 starting watts, 7000 running watts, 30 amps, and 240 volts.
  • 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 still find the generator a bit loud

One thing to keep in mind is that you may need adapters and extra installation effort to use the 30 amp outlet of the Champion 100520 8750 for actually powering your house.

Additionally, while many people will find this more than enough, the 10.5 hours run time at 25% load is somewhat below-average for this power level.

Even considering these small downsides, the Champion 100520 8750 is still a solid generator overall as the many happy customers can confirm.

If want a generator that is more budget-friendly than the top pick for quietest 8000 watt generator and don’t mind a few extra decibels, this option could be for you.

3. RYOBI RY906500VNM (72 dBA)

While the RYOBI RY906500VNM could be the right choice for certain individuals, it is important to highlight a few downsides of this generator.

First of all, the RYOBI RY906500VNM is not an inverter generator which means the high THD power you get is not suited for running sensitive electronics.

Even using this power for medium and big devices can speed up wear and tear.

Secondly, there are a good amount of cases where customers have technical issues with the RYOBI RY906500VNM.

Pros

  • Reasonable noise levels of 72 dBA
  • RYOBI RY906500VNM offers 8125 starting watts, 6500 running watts, 30 amps, and 240 volts
  • 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

Even if these issues get resolved by the three years limited residential warranty, this would involve spending some extra time and effort.

That being said, there are also a good amount of people who are happy with their RYOBI RY906500VNM.

Because it is not an inverter, this option is also relatively budget-friendly compared to many other of the quietest 8000 watt generators.

In combination with the good run time, GFCI outlets, and CO sensor, these things could convince some individuals to give the RYOBI RY906500VNM a chance.

At the same time, it is worth highlighting again that many people will prefer one of the other generators. Especially for running sensitive electronics.

4. DuroMax XP8500EH – Quietest dual fuel “8000 watt” generator (72 dBA)

The DuroMax XP8500EH gets a few minus points in this list of quiet “8000 watt” generators with its 8500 peak watts but it is a solid non-inverter.

As explained above, non-inverters like the DuroMax XP8500EH are not suited for running sensitive electronics.

DuroMax XP8500EH

That aside, one of the positive things about this reasonably quiet generator rated at 72 dBA is that it has a dual fuel function which allows you to run on propane too.

Since propane lasts longer than gasoline, the DuroMax XP8500EH can be especially useful for home backup power and off-grid living.

At least if you have an inverter or don’t mind high THD.

Pros

  • Reasonable noise levels of 72 dBA
  • DuroMax XP8500EH offers 8500 starting watts, 7000 running watts, 30 amps, and 240 volts (gasoline)
  • Dual fuel feature allows you to run on propane too
  • Impressive run time of 25 hours at 25% load
  • Good fuel efficiency
  • Electric start
  • Four GFCI outlets
  • Weight of 204 lb (92.5 kg)
  • 3 years limited residential and 1 year limited commercial warranties
  • Budget-friendly

Cons

  • High THD power is not suited for running sensitive electronics
  • More customer reviews would be welcome

Something else that really stands out in the DuroMax XP8500EH is its impressive run time of 25 hours at 25% load on a full tank of gas.

If the noise levels are low enough for you and your neighbors, this long run time could be useful for powering something like an AC overnight.

One thing to note besides the high THD power is that some DuroMax generators have a somewhat higher number of technical issues.

That being said, so far, the reviews imply that the DuroMax XP8500EH is a good reasonably quiet dual fuel generator with slightly more than 8000 peak watts.

5. GENMAX GM9000iE (62 dBA)

As you can tell from the decibel levels, the GENMAX GM9000iE is actually the second quietest model on this list of “8000 watt” generators.

GENMAX GM9000iE

However, with the relatively high 9000 peak watts and the number of cases where customers have technical issues with this generator, I decided the put the GENMAX GM9000iE lower.

Having more power capacity is nice but you want to keep in mind stronger generators also tend to cost more.

Pros

  • Low noise levels of 62 dBA
  • GENMAX GM9000iE offers 9000 starting watts, 7600 running watts, 50 amps, and 240 volts
  • Has a 50 amp outlet
  • Nice run time of 14.5 hours at 25% load
  • Less than 5% THD
  • Weight of 233.7 lb (106 kg)
  • Electric and remote start
  • Four GFCI outlets
  • CO sensor
  • Parallel capability
  • 1 year limited warranty

Cons

  • Relatively short warranty
  • Pricier than most of the other quietest 8000 watt generators
  • Decent number of cases where customers got a model that did not work as desired or early wear and tear

That being said, if you were already unsure about whether 8000 watts would be enough, you don’t mind the suboptimal reviews, and you have the budget, you can consider the GENMAX GM9000iE.

A benefit of going for this stronger inverter generator is that it has a 50 amp outlet which makes powering certain RVs, campers, and houses more convenient.

Additionally, the remote start of the GENMAX GM9000iE makes it more pleasant to operate this generator. Especially in suboptimal temperatures.

Many people will find the the GENMAX GM9000iE too pricey or not reliable enough.

However, if you don’t mind these things, you may prefer this option over the other models on this list of the quietest 8000 watt generators.
