If you want options for the quietest generators on the market then you found the right article. I’m going to give you my honest opinions on what models and brands you should buy. Some will be obvious, like the new Honda EU3200i, which is an impressive achievement in acoustic design. At 100% load it will output 2600W and its total noise level will be around 58dB. Running at 25% load (650W) its noise be around 54dB.
These numbers are phenomenal. For a frame of reference, a normal conversation is around 60dB. And by “normal” I’m referring to a conversation without yelling or speaking loudly. This means if you’re Italian, as I am, or if you’re from the Middle East, you can subtract about 10 dB from your idea of a normal conversation. I say this tongue in cheek, but different cultures do have varying degrees of “normal,” so keep that in mind.
The point here is that the Honda EU3200i is quieter than two people talking — from 23 feet away from the generator.
I’ll be referring to decibel levels a lot throughout this article so it’s important to have a frame of reference for the loudness of common sounds. This list will help you understand what decibel numbers compare to.
Decibel Ratings List: Common Noise Levels:
|Portable Generator||70 to 100 dB|
|Pop Concert||110 dB|
|Screaming Baby||115 dB|
|Jet Take-off||140 dB|
|Gun Shot||150 dB|
Basic Rules when Buying an Inverter Generator
I have to be honest with you, after spending time in comparing noise levels for inverter generators and trying to understand which one is the quietest I’ve come to a few conclusions. Most people are getting lost in the numbers and waste a lot of time comparing decibel levels, but this search for the quietest generator is largely a waste of time, and here’s why.
Most inverter generators are comparable to one another in terms of noise levels. Everybody talks about Honda being the quietest, and that’s true, BUT Honda generators are obviously quieter when the generator is idle in ECO-Mode with no load or a minimal load (under 500W).
In other words, Honda generators are much quieter than other generators when noise levels matter the least because people don’t usually run their generator with less than a 500W load. These minimal load decibel numbers are irrelevant but on paper they create the illusion that Honda is much quieter at all times and that is simply not true.
For example, a Honda Inverter generator ranges from 4db to 10dB quieter than other models, depending on which specific model you are comparing it to. I’m not going to dig up numbers for every single brand and model because this is precisely what’s wrong with the comparison. You need to think in relative terms. Honda begins noticeably quieter but quickly loses its advantage as the load increases.
In all honesty, when you compare a Honda generator running near 100% load, vs other leading brands, the quietness advantage is around 2dB to 4dB. Its specific decibel advantage (quietness) will depend on which brand and model you are comparing. Some models are quieter than others, and in all honesty, might be around 1dB quieter than a generator from Powerhorse, while a different model from Westinghouse might give the Honda a 4dB advantage.
The point is, when you compare numbers within a typical real-world load, the Honda is slightly noticeable, and in my opinion, not even worth worrying about or considering in your buying decision.
In fact, as you increase the load on a Honda generator it loses it’s edge. The fact is that other brands have almost caught up to Honda. Honda generators are considerably more than other brands and the question people often ask is: Are Honda Generators Worth the Money?
My answer is “yes,” but it’s not because they are quieter. In fact, the reason why Honda generators are better than other brands might surprise you. I feel that the emphasis has been put solely on their decibel ratings but that’s simply not true as it was years ago.
Variables that influence Generator Decibel Numbers
I’m writing this article in the hope it will help people make a decision far quicker then they normally would if they didn’t have this information. After countless hours of research and studying the data I wanted to give you some basic rules to help you make an intelligent decision. There’s a lot of confusing and contradictory information on the internet. My hope is this article will provide some practical advice.
One fact you need to accept is that decibel numbers vary. Every person will have their own set of numbers. People will make all kinds of claims about noise levels but the fact is, there are several variables that prevent consistent decibel measurements. Knowing these facts will help you cut through the nonsense and recognize when you are being misled.
VARIABLE 1: Sound Measuring Device
Generator noise levels are measured with a sound level meter (decibel meter, sound pressure level meter) which are available in two class types: Type 1 and Type 2 — also referred to as “class 1” and “class 2.” Type 1 has the tightest tolerances and widest frequency range. This would typically be used in a laboratory or clinical setting. This is the most accurate device with an allowable tolerance of ±1 dB.
Type 2 is a general use sound level meter and it’s also slightly less accurate, within a range of ±2 dB. Type 2 is perfectly acceptable for most use cases, but if I had my own generator brand I would use Type 1 for the most accurate reading. Extech is a leading brand that sells high quality decibel meters that meet these standards. You can also buy decibel meters for $30 on Amazon or you can use a smartphone app for free — but I would NOT put any legitimacy to the numbers from these cheap options.
I see many people on YouTube using an app to measure the noise level from various generators and they then proceed to recite those numbers as if they’re fact. Numbers derived from an app or from a generic ‘decibel meter’ are not to be trusted.
Variable 2: Environment
The immediate environment surrounding the generator as well as what the generator is sitting on can account for as much as 10 dB difference. For example, testing a generator on concrete, in a suburb, with nothing within 100 feet of your generator will register around 10 dB louder when compared to a generator on lush grass near a residential home, with other typical residential structures nearby.
The reason is simple, but may not be obvious to some people — the grass readily absorbs vibration as well as sound. A house will also absorb sound. Hard surfaces magnify generator sounds and vibrations. Wheels on a generator will minimize sound if the generator is on concrete, which means a generator without wheels will appear louder than a model with wheels.
The point here is the difference in environment can create the illusion that the quietest generator is loud, and if you’re unaware of the variables that affect noise levels you might choose the wrong generator. It’s important that you’re aware of how results may vary.
I just want to be clear on this because it’s important. The Honda EU2200is will idle at around 48dB in ECO mode — if you test it on grass. In your backyard, this same generator, will register noise levels at around 58dB — if placed on a concrete driveway or sidewalk (or road), and if there are no structures within 100 feet.
Variable 3: Where is the Sound Meter Pointed?
Pointing the sound meter toward the back — muffler side — will add an additional 5dB to 15dB, depending on how close you are to your generator. This is not trivial. From around 23 feet, where most testing is done, the decibel level will be around 5dB higher when compared to a measurement pointing at the front of your generator.
When you consider this point alone you begin to see how manufacturer numbers are misleading. The fact is, all generators have a muffler which inevitably point in a direction. The noise level will be noticeably louder to whoever, or whatever, is in the line of sound. In an ideal world, you only run your generator where there is nothing significant that would care about noise in one direction (IE. West). In other words, when running your generator, try to point the muffler where it will cause the least disturbance.
Unfortunately, this is not always possible. Your perception of your generator is likely skewed. The acoustics are different on your specific side where you experience the sounds of your generator, You might relish at how wonderfully silent your new generator is, but in the meantime your neighbor to the East is not so lucky as he gets the muffler side pointing directly at his bedroom.
He might even complain which might leave you confused because you find it perplexing that your neighbor would find your new Honda generator to be annoyingly loud. There’s always more than one side to any story, and when it comes to generators there’s at least 4 sides, and three of those sides are generally all in agreement. But that one side is always a little more annoying.
Just remember that one side will always be at least 5dB louder, depending on distance away from it. This additional noise obviously tapers off once a certain distance is reached.
Variable 4: Quality of Sound Matters
Every generator and brand has a distinct sound. The quality and rhythm of a generator will ultimately determine your experience of the generator, and most importantly, this emotional factor will ultimately determine the ‘loudness’ of the generator to your ears.
Many subtle variables determine how you perceive sound. For example, some generators have a fast idle which can be heard at the higher frequencies. I personally find this rhythm annoying, it goes something like this: “TICK-TICK…TICK-TICK..”
It’s common to come across two different generator with identical decibel levels but one sounds noticeably louder than the other because of the way the sound is structured. What you’ll notice is that some brands are inherently more attractive to your ears than other brands.
Perceived Loudness is very real and subjective. Another way to talk about this point is to consider the quality of sound that a generator makes. It’s visceral and you’ll know immediately whether you like it or you don’t. This is not an intellectual decision. In fact, it’s a lot like music. If you analyzed your favorite music you’ll probably find there’s a lot of repetition in the nature of the sounds, even across different musicians.
You don’t need to overthink this. I’m mentioning it so you can be aware of it. If you come across a generator that’s perfectly quiet according to its decibel rating, and yet you find it annoying, well now you know what’s causing this phenomenon. youTube is a good place to research the signature sounds of various generator brands.
Variable 5: How Far Will You Be from your Generator?
And lastly, this particular variable is simple — how far away will you be from the generator when you use it, on average? You need to evaluate your specific needs instead of relying solely on the data you get from a brand. In other words, you might never run your generator at its maximum load, which means the decibel rating at 100% load doesn’t really matter for your use case.
Focus on the features that matter to you and your specific needs. A quiet generator is always preferred over a noisy generator but that doesn’t mean you need the quietest. I recommend that you find an inverter generator with the features you need first and then choose a model from a reputable brand. I promise you he noise level
How Quiet is “Quiet”?
As far as a normal range for quiet, in terms of how we experience the world, I would categorize quiet between 50 dB to 60 dB. The hum of your refrigerator is around 50dB and a normal conversation is 60dB. Anything below 60dB would be considered “quiet.” The funny thing is, our lives are quite noisy. The moment we turn on a podcast, a blender, take a shower or turn on the TV, our environment becomes moderately loud.
I find it ironic that people place a lot of importance in buying a quiet generator but their own life is likely far louder than most inverter generators.
What Nobody tells you About Generator Noise Level Data
You should know that any decibel numbers you get from manufacturers are based on its noise level from 23 feet (and sometimes 21 feet). There’s no standard for measuring generator noise levels. This is the reason why few manufacturers provide real noise data. I recommend you ignore the numbers manufacturers provide. Their numbers are often misleading and are taken under ideal circumstances, under conditions that you’ll never experience in the real world. I don’t see the value in these idealized numbers with the exception of Honda. The one brand who knows exactly what they’re doing.
I’m bothered by a lot of things but nothing annoys me more than when people or corporations try to mislead, deceive or manipulate me. If you want to get me angry quickly then try to do one of these things to me. This topic has found a nerve with me. This topic has not been addressed by those responsible for setting the standards in this industry. There has been a massive failure by the PGMA (Portable Generator manufacturers’ Association) to create guidelines so that manufacturers can accurately measure the noise levels of their generators.
When you see statement such as: “as quiet as 52dB,” or “61 dB from 23 feet,” just be aware that these numbers are taken in ECO mode from 23 feet with ZERO load. In other words, the generator has nothing plugged in. Nothing is being powered. Why would you ever turn on your generator if you weren’t using it to provide power?
Honda and Yamaha actually provide useful noise ratings for all of their inverter generators. It’s not surprising since they are two of the most respected generator brands.
Honda is known for producing the quietest generators on the market. It’s a selling feature when your numbers are favorable. The industry can learn a lot from Honda and Yamaha. They give you the decibel level for the generator at 25% load and 100% (rated) load. You’ll notice that Honda does not provide the noise level of their generators with 0% load, in ECO Mode. Hmm, I wonder why?
The reason is precisely the same as what I said earlier — that number is useless.
Honda and the Future of Backup Power
It’s no secret that Honda makes the quietest inverter generators. If you’re new to generators, this might be new information for you, but if you’ve owned a generator before then you probably know about Honda’s reputation with their generator. Honda generators are excellent for the same reasons their cars and SUV’s are great — it’s the engineering.
Honda has a wealth of proprietary technology they’ve developed and tested, over decades. Ultimately, the reason people pay more for Honda is because their engineering enables their generators to be ultra-quiet, efficient and reliable. If it was easy to make ultra-quiet generators then every brand would be able to do it — but they can’t.
Why do people buy Honda over other leading brands? Reliability is typically the answer. Thankfully the competition from generator brands has been fierce over the past couple of years. This has been a fast growing sector with consumers, as people recognize the power grid is not as reliable as they once thought. Portable power will never go out of style.
There has also been a contagion effect with the spotlight that Elon Musk has put on the need for renewable energy thanks to the success of Tesla vehicles. This has made people more aware of battery backup technology, in general. This awareness translates into more people buying battery-powered generators, which have only become a viable alternative in the past two years, or so.
These “alternative” generators are known as portable power stations. They have many advantages over standard gas generators and inverter generators. Their main disadvantages are cost and they need to be recharged. But, this negative also becomes an advantage because power stations can all be recharged via solar and during an emergency fuel is typically scarce so being able to run off the grid and recharge the batteries means you can survive indefinitely and independent of nearby fuel sources.
The reality is, our world is moving towards electric power and portable generators are quickly moving in that direction. Solar capable generators are beginning to rival gas-powered portable generators. This is an option for you today, in 2023, depending on how much power you need and what you need it for. This is an important shift in the backup power industry and I suspect that many people will be skeptical reading this. Either way, Consumers have never had more quality options than they have today.
There are times when you really want (“need”) the quietest generator you can get your hands on. The food truck business is a good example as to when it’s worth spending extra money on the quietest generator you can buy. The last thing you want, if you own a food truck, is to have a loud annoying generator running beside your truck. This will likely force people to look elsewhere to eat.
The Honda EU3000iS has been a popular inverter generator for food trucks. In 2023 this classic model was replaced by the EU3200i. It’s better in every way and this is a perfect example for investing in the quietest inverter generator on the market. But, I’ll be the first to tell you that you don’t always need the absolute quietest because many of the leading brands make inverter generators that are very close to Honda, in terms of noise level.

►Note : I bought a 2019 Honda CRV in August for a very good reasons — value and reliability. After weeks of research and test driving I choose a Honda. Truly, Honda knows how to make an engine that will endure over time, and with generators, they better start when your life depends on it. What’s the cost of that?
I put my money where my mouth is. Honda quality is exceptional, but it may not be what you need, I understand. Buy what you can afford.
What’s the quietest generator you can buy IN 2023? There are a few NEW inverter generators we recommend for 2020 :
- Honda EU2200i (read review) : 57 dB at rated load / 48 dB at 1/4 load
- Yamaha EF2200iS (read review) : 57 to 65 dBA
- Westinghouse iGen4500 (read review) : As Low As 53 dBA
- A-iPower SUA2000iV : BUDGET Inverter — 58 dBA @ 50% Load – 21’ / 7m

In this article, we look at several quiet portable generators that we think you’ll love. If you’ve ever owned a portable generator you know that they can be annoyingly loud but thankfully technology has improved over the years and the options for consumers is growing. If you’re going to buy a generator, why not spend a little extra for the extra-quiet performance. It does depend on your budget. Fortunately you can still get a quiet generator for little money in 2020. In fact, they are getting cheaper year by year.

The Hunt For the Quietest Generator
I’ve got a quick story I think you’ll definitely be able to relate to. It happened on a campsite more than a few years ago. I’d just woken up from a wonderful dream. I was expecting to hear the birds chirping, or at the very least the wind blowing through the trees overhead. Instead, I was faced with one of the worst sounds I’ve ever heard in my life. The gentleman who decided to pitch his tent close to ours was running the loudest generator I’ve ever heard — and it was jarring, not to mention the annoying aspect of it.

Do you enjoy the sound of your alarm clock knocking you out of your deep sleep at 7am? Sadly, traditional gas generators have that same affect on your psyche. In the modern world, technology has advanced, meaning, if you have the money to spend, then buy the quieter generator.
Combo, Open Frame Gas Inverter : iGen4200 — Around 62dB (Review)
On the flip side, money is a very real issue for most people in the world. If you need backup power and have a limited budget then buy a cheaper gas generator. No need to feel any shame about that. My advice : BUY WHAT YOU CAN AFFORD, and don’t spend a penny more.
Below you’ll find INEXPENSIVE Generators, some are quiet, some are NOT :
Ever since then I’ve always been interested in finding the quietest generator possible which satisfies my needs. We usually need a generator for one of two reasons. Some of us love spending time in the great outdoors, and others want a generator handy in case the weather plays up and the lights go out. In either case, being able to use the quietest generator you can find will please your ears. We’re going to look at some of the quietest portable generators today, but before we do there is a few things to keep in mind.
Conventional vs Inverter Generators
We’ve covered the difference between the two different kinds of generators on the website in the past, but as far as noise is concerned there is only one winner. All other things being equal, an inverter model will always be a whisper quiet generator compared to its deafening nemesis, the conventional generator. In fact, the noise difference won’t even be close, because a conventional generator is designed to run at a constant speed no matter what you’ve got hooked up to it. Any inverter generator has the ability to throttle the engine speed depending on the load needed.
What Will Your Portable Generator Be Used For?
We need to clear up something crucial before we can even begin to talk about decibel levels. After all, would you really spend money on something if it’s not capable of satisfying your needs, even if it doesn’t make a lot of noise? The best quiet generator must also give you the power output you need to run a huge selection of things. As you know by now, you’ll either want your generator for camping trips or blackouts, so we’ll focus on those situations.
You’ll find inverter generators will come with 3 very common wattage ratings, but today the generators we’re going to look at will be rated as one of the following:
Please note — it’s also common to find inverter generators with a power output of only 1,000 watts, and they’re perfectly capable of running certain appliances. The trouble is, when you’re running more than one thing you’ll have to add the wattages up, and you’ll find 1,000W inverter generators won’t be capable of running lots of things at once.
2,000 Watt Generators
A 2,000 watt generator will allow you to have the option of exceeding what you might consider light power usage, yet they’re still extremely portable enough to carry anywhere with you. They also lend themselves better to appliances that require more power to run. We’re talking about things like heaters and microwave ovens, which can both come in handy when camping.
3,000+ Watt Generators
There isn’t much to say about 3,000 watt generators other than the fact they’re absolute beasts. If you own one, it will become your best friend whenever the power goes out and you need to keep your home running as much as normal. They’re even capable of handling an AC system, along with any other appliances you’ll need to use.

A Little List Of Appliance Wattage Requirements
Earlier on we said the reason a 1,000 watt quiet generator wasn’t perhaps the best idea in the world is because it couldn’t run a lot of things at once. We’ll go over some cool things you should know about a quiet portable generator, but first here is a little list of the wattage ratings of some common appliances you’ll want to run:
- Oven – 3,000 watts
- Laptop – 150 watts
- Coffee Machine – 1,500 watts
- TV – 200 watts
- Smartphone – 4 watts
- Portable Fan – 100 watts
- Stereo – 60 watts
- Water Heater – 500 watts
- Iron – 1,100 watts
- Toaster – 1,200 watts
- Refrigerator – 1,400 watts
- Blender – 300 watts
NOTE: You can use Honda’s wattage calculator to help you determine the right size generator. Also, click the image below and download the handy worksheet.

Calculating The Decibel Levels Of Generators
Before we move onto any of the more interesting stuff, I just want to make sure you know how the noise rating of a generator is calculated, as you’ll see the various decibel levels (dBA) being mentioned on the quietest generators as a major selling point. The US standard for calculating the dBA of a generator is carried out by calculating the noise level from 21-feet away using microphones, whereas the European standard is 23-feet using the same method. You’ll notice there isn’t much difference between the two, but now you’ll know where the dBA comes from.
Quiet Generator | Briggs & Stratton P3000
As a completely rough estimate, let’s assume all the quietest portable generators we’re going to be looking at today will be between 50 dBA and 60 dBA. This could also have something to do with whether the generator in question is running at or under full load, but they’ll usually fall in between those decibel levels. Now let’s compare them to some other decibel levels of noises I’m sure you’ve heard plenty of in the past:
- Rock Concert – 100 dBA
- Lawn Mower – 90 dBA
- Alarm Clock – 80 dBA
- Vacuum Cleaner – 70 dBA
- Home Computer – 40 dBA
- Human Conversation – 60 dBA
It’s hard to believe, but a whisper quiet generator isn’t as loud as a human conversation. Especially if it’s with your mother-in-law, though I’m sure you could already have worked that out.
More Power Equals More Decibels
This is going to vary depending on the model if a couple of generators have the same power output, which could come down to something as simple as a better engine. But more power will always equal more decibels, so a 3,000 watt generator will be louder than a 2,000 watt generator. The decibel level will also always increase as you add more appliances to the generator because you’ll require more engine power. Although that might sound obvious, it should be something you’re fully aware of so you’re not mislead by random figures later on.
Decibels Are Stranger Than You Think
Before we move onto looking at the quietest generators, there are some interesting facts you might like to know about decibels, because they’re actually a lot stranger than they seem.
The Numbers Don’t Really Make Sense
If you were to have a hearing test, you would generally be able to hear things at around 0 dBA. If you were exposed to 160 dBA it would destroy your ear drums, and you would feel pain at 130 dBA. The difference between 0 and 130 is obviously 130, but as far as decibels go it is around a billion times louder.
You Might Enjoy Different Decibel Levels
Have you ever been driven insane by someone having a normal conversation on the phone while you were in a coffee shop? And at home you might have been able to relax while listening to loud rock music. It’s easy to presume a lower decibel level is better, but you might personally prefer something a bit louder.
The Sound Of A Generator Is Subjective
When you own one of the quietest generators it won’t make much of a difference as you’ll not be close enough to hear it, but this cool fact still holds true. Even though generators sit at different decibel levels, you might like one better because of the sound it makes. Do you like one that hums away, or one that sounds like it’s chugging along?
The Quietest Generator You Can Buy
Now we’re ready to look at some of the quietest generator options available to you, and they come from a big selection of various brands. Some are from brands you would consider the industry leaders. I know you would like the quietest portable generator possible, but at the same time there are a lot of other things you’ll need to take into consideration before you find the right one for you. Therefore, we’ll begin by looking at exactly how loud each generator is, and then we’ll look at the other benefits of each inverter generator.
Champion Power Equipment | 75537i
3100W inverter generator. Still great in 2020.
- 2800 running watts/3100 starting watts.
- RV Ready – TT-30R outlet.
- 120V AC load / 12V DC outlet.
- Up to 8 hour run time at 25% load.
- 58 dBA at 23 ft.
- Wireless remote, push button electric and easy pull recoil start.
- Low oil shut-off sensor.
- USDA approved spark arrestor.
- Integrated mobility kit.
- Built in carrying handles.
Overview | Champion Power Equipment 75537i
Even though this Champion inverter generator produces a whopping power output of over 3,000 watts, it’s still only got a rating of 58 dBA at 23-feet. From the chart we looked at earlier, it’s quieter than a normal conversation. Although it’s when you’re standing 23-feet away, if you were running the generator while camping or in an emergency situation it’s likely to be that far away from you anyway. Another thing to keep in mind about the power output is that 3,100 is the starting watts, and it actually runs at 2,800 watts.
The generator runs off a Champion single cylinder 171cc 4-stroke OHV engine, and if it’s only running at 25 percent load a full tank of gasoline will last you a very respectable 8 hours. You would expect any generator so powerful to be pretty large, but even though it’s not tiny it’s still classified as portable. It has large handles to help you carry it around, which shouldn’t be too hard for someone strong as it weighs less than 100 pounds, but it’s got wheels built into it to help you whisk it around easily.
It’s capable of running at 120V AC load, and it also has a 12V DC outlet along with charging cables to cover all your bases. If you’re curious as to how easy it is to start and operate, along with its wireless remote it has a push button electric and easy pull recoil start. Perhaps its other crucial feature is the low oil shut-off sensor, because it’s always nice to know your expensive small quiet generator isn’t going to go up in smoke when you forget to fill it with oil.

Overview | Honda EU2000i
Honda are a legendary brand, and the EU2000i Camo is a legendary inverter generator. If you’re only running at 25 percent load, you’ll only reach a noise level of 53 dBA. On full load it will still only reach 59 dBA. To put that into perspective, the noise will be somewhere between listening to a normal conversation and sitting in a private office. Along with the throttle slowing down the engine, the Honda engine and special sound dampening materials help to make this one of the quietest generators you can buy.
New & Improved : Honda EU2200i : The Quietest Generator
It has a 98.5cc Honda GX100 engine, and has both 120V AC and 12V DC outlets. It’s packing 2,000 starting watts, and the running watts is 1,600. How much does the inverter generator weigh considering it can run appliances at home or while you’re outdoors? Surprisingly, it weighs around half the weight of the Champion generator we’ve only just looked at. You’ll have to see it before you have a true idea of how light it is, because when you’re walking around with it you’ll think you’re carrying a briefcase to work.
Sound comparison between the Honda EU2000i and the Yamaha EF2000iS, which seems to be its immediate rival among consumers.
We’ve talked about Honda having a superior engine, so how about some facts to back it up? For starters, it can run for roughly 3.5 to 8 hours on a single tank, which will depend on the load you’re running it at. If you’re not running it at full load it’s more than capable of chugging away all through the night. The fuel efficiency is even more unreal, because to run for those 8 hours all it takes is a single gallon of fuel. If you’re in need of double the power you can string a couple of them together too.
Yamaha EF2000iS 2,000W | Quiet Generator
Not only is this one of the quietest generators you can buy but it’s easily one of the best, if not ‘the best’ portable generators. Just have a look at the features the engineers have packed into this model.
- Powered by Yamaha’s MZ80; 79cc, air-cooled (fan assist), OHV, 2-valve, 4-stroke, single cylinder engine with electronic capacitor discharge (CD) ignition.
- Auto decompression system reduces engine compression to provide a light recoil starter pull for effortless manual starting.
- Cast iron cylinder liner provides excellent heat dissipation and extends service life.

Overview | Yamaha EF2000iS
Yamaha plays in the same league as Honda, and they seem to have the edge when it comes to decibel levels depending on how you look at it. When it’s running at full load, which won’t be every time you use it, you’re still only talking about a noise rating of 61 dBA. Where it shines is when you’re running your Yamaha EF2000iS at 25 percent load, because it drops all the way down to an almost silent 51.5 dBA. It has the same starting and running watts as the Honda, which are 2,000 and 1,600 respectively.
New & Improved : Yamaha EF2000iSv2
In case you’re worried about running too high a load on your inverter generator, Yamaha have included a special safety feature. The electrical overload breaker will ensure all the internal circuitry won’t get fried if you accidentally overload it. It has something in common with the Champion Power Equipment generator too, because it also has an automatic shut-off valve that cuts the power if your oil level is too low. It will be impossible for you to start it up again until all is rectified, so always have some spare oil handy.
Also comes in a cool camo design.
The engine is a Yamaha 79cc MZ80, and it will once again provide you with both standard AC and DC power outputs. If you were carrying either the Yamaha or Honda inverter generator it would be hard for someone to tell the difference, because this one will also look like you’re carrying a little briefcase around. It even weighs around 2 pounds less, although it’s only 44.1 pounds so it’s not like you’ll be able to tell the difference. Depending on the load you’re placing on it, the big selling point with this quiet generator might be the 10.5 hour running time when in economy mode.

Overview | Champion Power Equipment 73536i
You’ll notice a lot of differences between this Champion generator compared to the last one, although they’re still both excellent depending on your needs. This model is rated at only 53 dBA from 23-feet away, which might not seem like a lot even though it could be the difference between sounding annoying or not. There is a downside, because the 73536i only has 2,000 starting watts and 1,700 running watts. It’s still a perfectly good inverter generator, especially if portability is a concern because you won’t need wheels with this one.
It only weighs a touch less than 50 pounds, which is almost as light as the Honda and Yamaha generators. The only big difference with the Champion is the handle, and once you’ve seen it I’m sure you’ll agree the design could have been a little better. It contains a Champion 80cc single cylinder 4-stroke engine, which is more fuel efficient than you might expect. If you’re only running at 25 percent load it will run for around 9.5 hours, but what makes it better is the fact it’s only going to use a gallon of fuel.
The easy pull recoil start means you’ll have no trouble getting it going whenever you want to use it. Hopefully that should be for many years to come thanks to it being designed for a long life. It has a low oil shut-off sensor like its big brother, so it’s not going to fail you as soon as you forget to fill it with oil. The ease of maintaining your generator along with its economy mode will also help extend its life. We also can’t forget, it still supplies both 120V AC and 12V DC power, plus they can be stacked if you want something more powerful and portable than the 3,100 watt model.

Overview | Briggs & Stratton P3000
This P3000 SmartPower Series inverter generator from Briggs & Stratton is another monster. As such, it’s one of the loudest generators we’re going to review today, which is strange because at 59 dBA it’s still quieter than a normal conversation. It has 4 120V household outlets, a 120V 30A outlet, a 12V DC power outlet, and on top of all that it also has a single USB port. The 171cc engine has 3,000 starting watts and 2,600 running watts, plus because the power output is so high it is perfect for backing up your home.
When it’s running at 25 percent load it will last for around 10 hours, and even though the power output is huge it will still only take 1.5 gallons to fill the tank. Its easy-to-read LCD screen will tell you exactly how long it has left to run before you need to fill it up again. The LCD screen also displays maintenance reminders, and although you should keep a close eye on them there are safety features built into the generator. It will shut down automatically as soon as it senses there isn’t enough oil.
It is larger than the briefcase-style generators, although Briggs & Stratton have made it as portable as possible for you. The design of the handle and the wheels make it feel like you’re wheeling a suitcase around the airport. The weight is roughly 30 pounds heavier than some of the 2,000 watt models, which isn’t too much of a difference. It’s also unlikely you would ever need this considering the large power output, but as with any decent inverter generator you’ll be able to hook it up to another one for double the power, although I’m not sure you would need the parallel port unless you live in a mansion.

Overview | WEN 56200i
I’d like to introduce you to the quietest generator we’re going to look at today. With a noise rating of only 51 dBA at 25 percent load, it’s right in the middle of the sound you’d hear from a conversation and the noise coming from a computer. Even though it literally is a whisper quiet generator, it doesn’t lack power. It has 2,000 starting watts, and still easily hits 1,600 running watts. It also packs a 79.7cc 4-stroke OHV engine under its hood, with 3 120V AC outlets, a 12V DC outlet, and a USB port thrown in for good measure. Even though it’s the quietest, it’s still not the lightest.
The inverter generator weighs 48 pounds, so it’s a couple of bags of sugar heavier than all the other lightweight generators we’ve looked at. You’ll still be able to carry it around by the handle like a little briefcase. The WEN 56200i gas tank has the capacity to hold a single gallon of fuel, which will keep running for around 6 hours. This time instead of only being able to run at a quarter load it will be able to run at a half load for the 6 hours, so if you’re running on a lesser load it’s going to keep working all night.
The biggest safety feature we’ve looked at so far is the automatic low oil shut-off, which the WEN 56200i has in case you were wondering. It will also shut off automatically when it senses your fuel is running too low, and both of them combined will safeguard the circuitry along with other parts of the generator from damage. There will be indication lights on the front panel, so you’ll easily be able to see what is going on at all times. The total harmonic distortion at full load is only 1.2 percent, so it’s a great choice for vulnerable electronics, but so are all the others too.
The Quietest Generator You Should Opt For…
The way I see it, you have a couple of different options when trying to choose the best quiet generator. Let’s start by saying they’re all amazing, and I’m sure if you were gifted any of them you would have no complaints. That being said, there are glaring differences even though they are all so quiet. The price needs to be taken into consideration, but the expensive ones have a better engine and they’ll last you longer. The power output might be more important than anything else depending on what you need it for.
You could even be a fan of some of the smaller things like the shape, weight, or safety features. I’m not sure if you can go wrong with any of them, so like any other purchase you’ll need to carry out due diligence. Choose the ones you think you like best, and when you’ve decided you can click through and read the reviews past customers have left. It’s the only real way you’ll know what you’re getting, and because they’re all quality generators (and brands) the mountain of reviews will help you come to a final decision.
