The Top 10 Quietest Portable Generators

Most people dislike excessive noise. Ambient humming of a noisy generator is ought to spoil your day, which is why buyers list the noise levels of a generator as one of the key factors they consider before purchasing one.

You should do the same. But which generators are the least noisy?

In this article, I have created an updated, ranked list of 10 most quiet portable generators currently on the (US) market. Unsurprisingly, they are all inverter generators, since low noise levels are one of the advantages they have over conventional units.

Note that the listed units do not include color or other variations of the same device and are only limited to portable generators with publicly listed noise levels. Be our guests and enjoy the reading.

Before proceeding further, make sure to consider (or remember) the following:

  • Decibel (dB), the unit of sound volume, is on a logarithmic scale. This means that the perceived noise does not scale linearly with their value (they do not add up as you would if e.g., adding on weight). Instead, an increase of 10 dB doubles the perceived volume.
  • For the same reason, running two generators in parallel will NOT double their decibel value.
  • Quite unintuitively, running two generators in parallel will also NOT double the perceived volume. Their noise levels increase by roughly 3 dB.
  • Note that some manufacturers don’t list the noise levels of their portable generators and therefore, quieter generators may be out there.
  • Also note that there currently aren’t any measuring standards strictly imposed by US governmental or regulatory bodies for noise emissions of portable generators.
  • Most manufacturers measure the sound levels at 23 feet. However, the load they apply to the generator during the measurement can fluctuate significantly by manufacturer. Accuracy of direct comparison therefore cannot be guaranteed by default.

Without further ado, here is the top 10 quietest portable generators currently on the market!

Zoom on the Quietest Portable Generators

Honda EU1000i

Honda EU1000i
Running Watts900W
Starting Watts1000W
Starting systemRecoil
Weight28.7 lbs
Noise rating42 dBA
Parallel capableYes
AC outlets2
DC outputNo

Given its noise rating of 42 dB (just slightly more noisy than a library), the Honda EU1000i is the most quiet of all the portable generators in our database.

The Honda EU1000i in use

The Honda EU1000i

This little beauty reaches up to 1000 starting watts and 900 running watts, with its 49.4 cc, OHV 4-stroke, Honda GXH50 engine. It is a great device for generating power on-the-go, a camping trip, or small scale DIY tasks.

The generator's power output can be conveniently collected through the EU1000i's control panel using its 2 AC outlets (duplex NEMA 5-15R).

The EU1000i is also parallel capable, which means that it can be hooked up to another compatible generator for additional power and an inverter generator, with a max THD of 3%, allowing you to power sensitive electronic devices directly (phones, laptops, etc.).

The Honda EU1000i's runtime reaches up to 6.8 hours if measured at a 25% load - a somewhat deceiving value given its specs if you asked me. Despite this low runtime, the EU1000i is perfectly suitable choice for surviving extended power outages or spending most of the day off-grid.

It weighs 28.7 lbs, which is lightweight for its power output, and has approximate dimensions of 17.8 x 9.5 x 14.9", making it a compact unit when compared to similarly powerful alternatives.

The unit is CARB-compliant and EPA-approved (which means it can be purchased in any of the 50 states). And thanks to a low oil sensor, which prevents engine damage and circuit breakers to prevent overload, the unit can be operated safely even when you aren’t always around. It also features Honda's CO Minder, a carbon monoxide monitoring technology which automatically shuts the generator down when CO levels become too high.

In conclusion, we rate the Honda EU1000i's price expensive, considering its power.

PROS
  • Parallel capable
  • Inverter
  • CO Minder
  • Lightweight (28.7 lbs)

And with its parallel capability, these ratings can be easily doubled by coupling the generator along with another device!

Honda EU2200i's power can be reaped for up to 8.1 hours, at a 25% load. This is a somewhat deceiving value considering its power. That said, the EU2200i stays perfectly suitable if you don't want to fear running out of fuel in the middle of the night.

The Honda EU2200i is also an inverter generator and thus, can safely power THD sensitive electronics, such as cell phones or laptops (THD <3%). It weights 47.4 lbs, which means that it is as lightweight as many of its similarly powerful peers

The EU2200i's power is fed through a control panel equipped with 2 AC outlets (duplex NEMA 5-20R).

On top of that, this generator is equipped with a low oil sensor, which prevents engine damage and circuit breakers to prevent overload, providing you, the user, comfort and safety. It also features Honda's CO Minder, a carbon monoxide monitoring technology which automatically shuts the generator down when CO levels become too high. The unit is CARB-compliant and EPA-approved (which means it can be purchased in any of the 50 states).

As for its price, the Honda EU2200i is considered to be somewhat expensive, in comparison to other generators with similar specs.

Next on our list of the most quiet generators, at 25.9 x 17.6 x 22" and 130.7 lbs, is the Honda EU3000iS and its delightfully low noise rating of 50 dB.

The Honda EU3000iS in use

The Honda EU3000iS

Its 196 cc, OHV 4-stroke, Honda GX200 engine can reach the following wattages: 3000 starting watts and 2800 running watts. With these wattages, this model is ideal for anyone who wants to generate power on-the-go, wants to bring it on a camping trip, or wants to do some small DIY tasks. And if these numbers weren’t just good enough for you, with its parallel capability, they can be easily doubled by coupling it along with another parallel capable device!

The aforementioned power may be drained for up to 20 hours on a single tank, at a 25% load. This is a quite impressive value for a generator of this power ouput. Thus, the Honda EU3000iS is ideal if you don't want to fear running out of fuel in the middle of the night.

As is the case for some other devices on this list, the Honda EU3000iS is an inverter generator and accordingly, can be used to safely power sensitive electronics, cell phones or laptops, with its THD <3%.

It also has the advantage of featuring, in addition to its traditional recoil start, a convenient electric start.

The EU3000iS's power is harvested through its control panel that is equipped with 3 AC outlets (duplex NEMA 5-20R and NEMA L5-30R).

To top this off, the unit is equipped with a low oil sensor, which prevents engine damage and circuit breakers, which prevent overload, providing us with a feeling of comfort and safety. It also features Honda's CO Minder technology which automatically shuts the generator down when CO levels become too high. The unit is CARB-compliant and EPA-approved (which means it can be purchased in any of the 50 states).

Lastly, when compared to other portable generators of similar output, the Honda EU3000iS's price should be considered average.
