5 Quietest 6500 Watt Generators To Keep Noise Down

Discover the quietest 6500 watt generators you can power a nice amount of devices without annoyance from crazy noise levels.

Quietest 6500 watt generators overview

Something to note before listing the options is that the 6500 peak watt category only included a few quiet models.

Because of this, I also included generators with up to 7250 peak watts.

1. Honda EU7000iS – Quietest 6500+ watt generator (7000 peak watts, 52 dBA)
2. Honda EM6500SX – Quietest 6500 peak watt generator (64 dBA at 50% load, non-inverter)
3. GENMAX GM7250iEDC (7250 peak watts, 63 dBA, dual fuel)
4. Briggs & Stratton Q6500 (66 dBA)
5. Westinghouse wGen5300 (6600 peak watts, 68 dBA, non-inverter)

As you can expect, 6500+ watt generators lower on the list may be slightly louder but could still be the right choice.

Other details I looked at

For this selection of the quietest 6500 watt generators, I listed the 6500 to 7250 peak watt models with the lowest decibel ratings and checked the reviews on mentions about this area.

That being said, since you likely also want a generator that performs well, I looked at other details for the in-depth reviews too.

Some of the other details I took into account are:

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

5 Quietest 6500 watt generators detailed reviews

As briefly mentioned, you likely want a quiet 6500 watt generator that performs well in other areas too.

The detailed reviews of the options below can help you find the best model for your situation.

1. Honda EU7000iS – Quietest 6500+ watt generator

The Honda EU7000iS is the quietest 6500+ watt generator on this list with an impressive 52 to 58 dBA at 25% to 100% load.

Whether you actually want to invest in this machine is a different question. The Honda EU7000iS may be great in other areas too but it is also very expensive.

One of these things that positively stands out is the connectivity with the Honda My Generator App.

This allows you to see performance metrics and to start and stop the generator from a distance.

In turn, figuring out how many more appliances and tools the Honda EU7000iS can handle and just its general operation become a lot more convenient.

Additionally, the long run time of 16 hours at 25% load makes this quiet 6500+ watt generator great for running a medium AC, refrigerator, and/or freezer overnight.

The CO sensor and GFCI outlets also help you avoid too much carbon monoxide buildup and overloading the generator.

One thing to note is that there are a few very exceptional cases where customers had issues with the Honda EU7000iS.

That being said, the customer reviews are still relatively positive.

In turn, the Honda EU7000iS could theoretically be worth it if you have the budget and value silent operation and clean inverter power enough.

2. Honda EM6500SX – Quietest 6500 peak watt generator

The Honda EM6500SX is the actual quietest 6500 peak watt generator although you likely care more about its 64 dBA to 66 dBA (at 50% to 100% load) noise levels.

One thing to note first is that this is not an inverter power.

In turn, the high THD power you get is not suited for running sensitive electronics like a TV, microwave ovens, and even certain refrigerators.

Additionally, the Honda EM6500SX is another model that is expensive compared to many other quiet 6500 watt generators.

You want to know about the relatively bad fuel efficiency and a few exceptional cases of issues too.

That being said, the Honda EM6500SX is also solid in many areas and Honda still has a reputation for durability and reliability.

In combination with the Honda My Generator app connectivity, CO sensor, and four GFCI outlets this could convince you to consider this generator.

At the same time, it is also worth mentioning again that this is still a relatively expensive generator without inverter technology.

In turn, many people will prefer one of the other options on this list of the quietest 6500 watt generators.

3. GENMAX GM7250iEDC

The GENMAX GM7250iEDC is another generator with more than 6500 peak watts (7250 watts) but its low noise levels of 63 dBA earn it a spot on the list.

You may also like that this model is able to run on propane too thanks to its dual fuel feature.

Since propane typically stores longer than gasoline, this fuel type can be a more convenient way to be prepared for power outages and better for off-grid living.

Additionally, if you only plan to use your quiet 6500+ watt generator occasionally, propane generally involves less maintenance work than gasoline.

You do want to know that similar generators from GENMAX do not have the greatest reviews due to relatively high rates of technical issues.

This GENMAX GM7250iEDC does not have the most reviews yet but there are already some mentions of similar technical issues.

Additionally, GENMAX support does not have the best reputation. Even if you are still in the one year warranty period.

In turn, you likely want to turn to other quiet dual inverter generators to get a lot of clean power from propane.

If you don’t like the prices and sizes of models with much more than 6500 peak watts, you can also consider putting two smaller models in parallel.

4. Briggs & Stratton Q6500

At first sight, the Briggs & Stratton Q6500 may look like a nice quiet 6500 watt generator.

With its reasonable price, the 14-hour run time at 25% load and inverter power can seem like a good deal.

However, while its 66 dBA noise levels do earn it a spot on the list, you likely don’t want to invest in the Briggs & Stratton Q6500 due to the high rate of technical issues.

These technical issues involve both never being able to start the generator and experiencing early wear and tear very soon.

From the customer reviews, it also looks like the warranties don’t mean much either. There are a number of mentions that Briggs & Stratton support is not helpful.

The technical issues are likely already enough to turn you away from the Briggs & Stratton Q6500 but its fuel efficiency is bad too.

In short, the Briggs & Stratton Q6500 may look interesting at first but you want to stay away from this 6500 watt generator due to the many technical issues.

Unless you want a pricey paperweight.

5. Westinghouse wGen5300

The Westinghouse wGen5300 is not that quiet for the human ear with noise levels of 68 dBA (typically measured at 25% load and 23 feet away).

That being said, for stronger non-inverter generators of 6500 watts and more, this is still very reasonable.

And even if decide this is silent enough for your uses, you want to remember that non-inverter means the Westinghouse wGen5300 is not suited for sensitive electronics.

There are also a few exceptional cases of technical issues although this is still a very reliable generator.

The run time of 14.5 hours at 25% load is not the highest on the list but is still nice.

You should be able to get through the construction site workday, DIY session, power outage, etc. with relatively few refueling sessions.

Additionally, elderly individuals or just people who don’t like the recoil will be happy to hear the Westinghouse wGen5300 is available with an electric start too.

Besides these things, the Westinghouse wGen5300 is relatively standard which is a good thing for its budget-friendly price.

This is definitely not the quietest 6500+ watt generator on the list but if the 68 dBA sound bearable to you and you don’t need an inverter, the Westinghouse wGen5300 could be for you.
