5 Quietest Large Generators For A Lot Of Power

Discover the quietest large generators so you can power a lot without disturbing your ears or neighbors too much.

Quietest large generators overview

1. Honda EU7000iS – Quietest large generator (52 dBA, 7000 peak watts)
2. Powerhorse 7500i – Best large quiet generator (55 dB, 7500 peak watts)
3. Champion 201175 – Quietest large dual fuel generator (61 dBA, 8500 peak watts)
4. AIVOLT 10000 (61 dBA, 10000 peak watts, dual fuel)
5. GENMAX GM9000iE (62 dBA, 9000 peak watts)

It is worth quickly noting that once you get above these power levels, large portable generators tend to be similar in their loud noise levels.

Other details I looked at

The list above is basically a ranking of the quietest 6500+ peak watt generators on the market.

However, to make your decision easier, I also looked at some of the following details for the in-depth reviews below:

• Run time, fuel efficiency, outlets, fuel types, etc.
• User reviews
• Anecdotal reviews from experts
• Price
• Brand trustability and reputation
• The performance categories below

5 Quietest large generators in-depth reviews

Low noise levels are nice but you likely want a portable generator with good performance in other areas too.

The in-depth reviews of the quietest large generators can make it easier to find the best model for your situation.

1. Honda EU7000iS – Quietest large generator

With noise levels of 52 to 58 dBA at 25% to 100% load and 7000 peak watts, the Honda EU7000iS is the quietest large generator on the market.

Whether you actually want to invest in this portable generator is a different question.

A big reason for this is that the Honda EU7000iS is relatively expensive. Even compared to other quiet large generators.

Secondly, even at this price point, there are still a few exceptional cases where customers have technical issues with this inverter generator.

On the flip side, the Honda EU7000iS is still relatively reliable overall and has other positive points too.

For example, you can connect to this large generator with your phone through the Honda My Generator app.

In turn, you can start, stop, and track the performance of the Honda EU7000iS remotely from the comfort of your home, RV, or party tent.

Additionally, thanks to the nice run time of 16 hours at 25% load, this quiet generator should be good enough to power things like a reasonably sized AC throughout the night.

Many people will turn to one of the other quiet large generators due to the high price.

However, if you really like the remote operation and/or the Honda brand, you could consider investing more in the Honda EU7000iS.

2. Powerhorse 7500i – Best large quiet generator

The Powerhorse 7500i is not the cheapest generator either but compared to the Honda EU7000iS, it does perform a lot better in this area.

Additionally, the Powerhorse 7500i comes with more starting and running watts.

At the same time, you do want to know that the Powerhorse 7500i is a few decibels louder, slightly less fuel-efficient, without remote operation, and not as proven as the Honda EU7000iS.

In turn, your kWh (measurement of electricity quantity) will be slightly pricier, the quality is just a bit less certain, and the operation is less convenient.

That being said, since these downsides are relatively small, you will likely agree that the Powerhorse 7500i gets the title of the best large quiet generator.

Similar to the Honda EU7000iS, the Powerhorse 7500i comes with a good run time of 16 hours at 25% load which should be enough to last through the night.

The extra low 1.5% THD may not be that much better than 3% but you should have no worries running your sensitive electronics with this power.

Additionally, while more customers for the Powerhorse 7500i specifically would be welcome, customers tend to be happy with Powerhorse generators.

In short, you will likely prefer investing in the more reasonable price yet quality details of the Powerhorse 7500i.

3. Champion 201175 – Quietest large dual fuel generator

Since the two previous options were gasoline-only, Champion 201175 is the quietest large dual fuel generator on the market.

In simpler words, this inverter generator allows you to generate power from both gasoline and propane at relatively low noise levels.

This can be a benefit since propane typically stores longer than gasoline.

In turn, off-grid living and staying prepared for unexpected power grid issues require less time and attention.

In that sense, you could describe the Champion 201175 as one of the quietest generators for home backup (although you can use the previous models for this too).

The main downside of the Champion 201175 you do want to keep in mind is that there are not that many customer reviews yet.

At the same time, it is worth noting that Champion generators tend to be some of the most reliable models on the market.

In combination with the nice warranties and solid features, the Champion 201175 is likely the best quiet large dual fuel generator for you.

Do keep in mind that the Champion 201175 offers slightly fewer running watts when using propane.

In some situations, a bigger dual fuel inverter generator (or two smaller ones in parallel) could be necessary.

4. AIVOLT 10000

With a noise level rating of 61 dBA, the AIVOLT 10000 should be about equally quiet as the Champion 201175 8500.

However, in the absence of third-party decibel tests or many relevant customer reviews, I generally put the stronger generators lower.

You do want to know that AIVOLT is not the most proven generator brand.

In turn, there is a certain amount of uncertainty about the quality of the AIVOLT 10000 at a bigger scale.

At the same time, you may like the customer reviews enough to consider a quiet large generator that offers 1500 more peak watts and 1000 more running watts than the Champion 201175.

The AIVOLT 10000 also offers the dual fuel benefits mentioned above.

This can be extra helpful for purposes like house backup power or off-grid living. Especially in combination with the 50 amp outlet.

Besides that, the AIVOLT 10000 is also impressive in areas like its gasoline run time and fuel efficiency.

The remote start makes operating this inverter generator more convenient too.

So overall, the AIVOLT 10000 looks great on paper.

Whether you actually want to invest in this model depends on how much you mind the small number of customer reviews.

5. GENMAX GM9000iE

The GENMAX GM9000iE deserves a spot on the list of the quietest large generators thanks to its noise level rating of 62 dBA and 9000 peak watts.

At the same time, you likely don’t actually want to invest in this model because of the high rate of technical issues and early wear and tear.

And even if these issues do happen within the short one-year warranty, GENMAX support does not look the most helpful after checking the customer reviews.

Similar issues apply to the GENMAX GM9000iED which is the dual fuel version although the reviews of this alternative do look slightly less bad.

Everything above still applies but you may wonder if there are any reasons to consider the GENMAX GM9000iE anyway.

The main detail that positively stands out in this quiet large generator is the remote start.

After the initial setup, this allows you to conveniently start and stop the GENMAX GM9000iE from a distance.

The 62 dBA, 14 hour run time at 25% load, electric start, and CO sensor are nice additions in terms of convenience and safety too.

However, these things are not of much use if your GENMAX GM9000iE does not actually produce power.
