3 Best Quiet Generators

Have you ever been kept awake at night by the noise coming from a generator? If so, then you’ll understand the importance of finding a quiet generator, which is ideal for nighttime use.


Whether it’s for a campsite or a worksite, one of the most crucial factors to consider when shopping for a generator is the noise level, and you want to ensure that’s as low as possible. When making use of a generator around other people, the noise factor can be a major issue.


But no need to worry; we’ve got your covered: Simply go through our quiet generator reviews.


Please be aware.. the absolutely most silent generators are solar generators.


However, solar generators don’t always have as much power as conventional gasoline or propane generators. We will only discuss conventional and inverter generators in this list.


Here are best quiet generators we’ll be looking at in this article:

Top 5 Best Quiet Generators 2022


WEN 56200i 2000 Watt Inverter Generator

WEN 56200i  is among the best inverter generators and works very quietly. The noise level of the unit is similar to an everyday conversation. Also, it supplies clean energy, which has no voltage drops and spikes.


Unlike conventional generators, the machine produces much less noise and is also ranked high among other inverter generators as regards noise level. The WEN 56200i delivers 1600 running watts and 2000 surge watts.


It has a 79.7 cc 4-stroke OHV engine, which runs at a super-quiet 51dB at a 25 per cent load. The generator is quieter than your window AC or a normal conversation between 2 people. This extremely low noise level makes it an excellent choice for situations — like tailgating, camping, or hunting — when you’re keen about keeping your generator operating as quiet as possible.


The generator, which was invented to emulate a pure sine wave, confines THD (total harmonic distortion) to below 0.3 per cent at 0% load and also below 1.2 per cent at 100% load. So, it can safely operate vulnerable electronics, such as your smartphone, tab, monitor, and laptops.


In addition to these, the design ensures that this quiet generator is extremely light to carry as well. Also, it’s a very fuel-efficient generator with its 1-gallon tank capable of running for up to 6 hours at 50 per cent load, which is a great result in comparison with nearly all the other generators currently on the market.


The unit offers one 12V DC receptacle, one 5v USB port as well as two three-prong 120V receptacles. With the economy mode throttle, the generator’s motor can automatically adjust the fuel consumption, preventing unnecessary usage of gasoline.


The WEN product provides a two-year warranty, backed by a nationwide network of competent service specialists, along with a friendly consumer helpline.



  • Extremely quiet running at 51dB
  • Easy to use
  • Great value for money
  • Lightweight as it’s easy to carry with just one hand
  • Two-year warranty
  • Features economy mode for enhanced fuel efficiency
  • Friendly customer support service


  • Plastic Finishing
  • There’s no fuel valve



Honda EU3000iS Generator

The Honda EU3000iS  features a quiet range of 49 – 58dB, which ensures it won’t constitute any sort of disturbance to your neighbors while working. It produces significantly less noise than a typical generator. Also, while the unit sips fuel, other similar generators guzzle it.


It features an eco-throttle mode, which enables rationing of the fuel. But when it’s even operating at full power, you can look forward to getting great ‘mileage’ out of the generator.


The machine starts with a quick pull and provides your home or campsite with reliable & safe power. But it’s hefty as it weighs well over 150 pounds (including fuel). Even with its small size, you need to take the weight into consideration before any other factor if you intend moving the generator often or making use of it in your residential vehicle or another vehicle.


One aspect of this unit you may not like is that it ships without oil. So, you must have oil handy to get it started on arrival. Also, you may want to get your tools ready to make sure everything is in its proper place before you start up the inverter.


Apart from oil (and possibly some tools), you’ll also want to get a 12V charger cable ready to charge external batteries because Honda doesn’t provide one with this inverter.



  • Runs at 49 – 58 decibels
  • Has low dBA output
  • Electronics-safe inverter power
  • Ensures efficient fuel consumption
  • Auto shutoff when oil is low
  • Eco-throttle to save fuel


  • Features no USB outlets
  • Weighs around 200 pounds (including fuel)
  • Doesn’t ship with oil



Yamaha EF2000iSv2 Inverter Generator

The Yamaha’s EF2000iSv2  is a lightweight and compact unit, which is one of the best quiet generators on the market. Also, it is among the smallest portable inverters out there.


Though it’s small, the model offers you a long runtime due to its remarkable fuel efficiency through the Smart Throttle. The Smart Throttle feature is a load-sensing RPM control for adjusting the engine speed depending on the load. It will help you save fuel and also helps in reducing noise when the machine is running at lower speeds.


You can get around 10.5hrs of runtime at 25% load, which is quite impressive for such a small unit. Also, you can make use of the generator’s parallel function for pairing it up with a 2nd generator from Yamaha (no cables included).


Concerning noise, the Yamaha EF2000iSv2 works within the range, 51.5 – 61dBA, and none of the 2 limits is terribly loud. It also comes with rubber vibration isolation feet that Yamaha says also helps in reducing noise and ensuring things run smoothly.


And when you need to stow the machine away, you’ll find the gasoline petcock quite useful. The option lets you cut off gasoline to the carburetor for storage, making sure that no buildup will occur when you break it out again for your next use.


Additionally, you may feel that it’s necessary to add to (or change) the oil frequently, partly because of the oil reservoir’s small size. But that’s just a minor drawback.



  • Works quietly at 51dBA
  • Smart Throttle for fuel efficiency
  • 3-year warranty
  • Offers easily visible fuel gauge
  • CARB Compliant
  • Oil Watch Warning system
  • Gasoline petcock for storage


  • Uses a lot of oil
  • Expensive



Briggs and Stratton P2200

The Briggs and Stratton P2200  features a computer-controlled engine, offers efficient and consistent power, which is also quiet. Easy-to-use, the unit delivers 1700W of power and can be transported without hassle, having a light weight of only around 55 pounds. While carrying handles are a great option on the machine, it’s really the lighter weight that helps the most for maneuverability.


As regards drawbacks, one potential issue with the model is that it won’t ship to customers in California. Sadly, the inverter generator will fail emissions rules for the state, and so far, the maker hasn’t designed an option that’s California-compliant.


While the decibel output is relatively low, it isn’t the quietest generator on the market. However, in terms of sticking to a budget, it could be your best choice, so long you’re not resident in California.


It provides an 8-hour runtime (at one-quarter rated load), which implies that you’ll have power aplenty for most of your needs for the whole day without going low on fuel.


But there’s no eco mode, so you won’t have much control over the fuel consumption other than powering down appliances.


Overall, the Briggs & Stratton unit is among our top choices for a handy and easy-to-run portable generator, which works reasonably quietly.



  • Runs quietly at 59dBA operating volume
  • Maneuverable (with handles) & lightweight
  • Offers multiple outlets & parallel connector port
  • USB compatible
  • 2-year warranty


  • Lower running Watts
  • Doesn’t ship to California

Frequently Asked Questions (FAQs)

Can I Use One of Those Quiet Generators to Power a Whole House in an Emergency?

No, that’s not possible. Nearly all the quiet generators come with a maximum running wattage of no more than 4000W, and that’s not enough to provide electricity for the whole house.


What is the Size of Generator I Need?

The first step you need to take here is to determine which appliances and devices you’re planning to run. Then, add their combined wattage to see if it’s less than your generator’s total wattage.


Don’t know how to do this calculation? You can learn more here.


How Loud is a Generator with a 74dB Noise Level?

74dB is a noise level that’s comparable with your average vacuum cleaner. A portable generator that runs at this level can constitute quite a nuisance to you and your neighbors. Fortunately, none of the options above works at this disturbing sound level.


Can I Make Use of a Muffler for Quieting a Generator?

Yes, you can make use of a muffler for further reducing the noise levels produced by a portable generator. In some quiet generators, like the Yamaha EF2000iSv2 reviewed above, there’s already a built-in muffler, ensuring you won’t have any need to buy one separately.


But it’s not all small, quiet generators that work well with external mufflers. Hence, consider checking it before purchasing one, whether it supports an external muffler or not.


In any case, the one-size-fits-all solution we’ll recommend is to buy a dedicated enclosure.


Are Propane-powered Generators Considered Quieter?

Generally, whether a portable generator is powered by gas or propane, it makes no much difference to the sound level. It’s the design that’s more important. For instance, Champion 3400 Watt Dual Fuel Generator works very quietly, and that’s due to the fact that it’s a well-built RV generator. The fact that it accepts propane is just a handy addition instead of something that makes the unit quieter.


Are the Generators Above Quiet Enough to use at Official Campgrounds?

If your campground has it on the list of its rules that portable generators aren’t permitted to be used at all times, then you can’t use one in that place no matter how quiet the unit is. But nearly all the federal campgrounds obey a general rule, which states that portable generators that run under 59dB are allowed to be used during the non-quiet times (typically before 10 PM).


Also, you can consider buying a portable solar power charger. Those portable generators are not only noiseless but also powerful enough to supply electricity for smaller electronics, like mobile phones, laptops, cameras, and camping lights.


In any case, consider checking the individual rules of each campground and ensure that you do your best to reduce the disruption caused to your neighbors.


Is it Necessary I Ground a Generator?

There’s obviously no harm in grounding your generator to give yourself additional peace of mind. But if you use a modern inverter generator, no need for that. Lots of people make use of them without grounding, and they’ve no issues.


How Long Does a Portable Generator Last?

This is dependent on 2 factors. One, certain generators have better fuel efficiency than others, which means they use less gas, which allows them to last longer on a single refuel.


They can achieve it due to different hi-tech techniques, which adjust the way the engine works based on current electricity consumption.


Two, it depends on the number of appliances you plug into your generator. The majority of companies advertise the runtime of a portable generator at a quarter rated load.


But if you choose to plug in an appliance, which consumes almost all the available running wattage; that means the generator will be working at nearly 100 per cent load and will consume much more fuel.


If you want to get rough estimates, keep in mind that on average, a typical camping generator can last for 6 – 8 hours.
