Note: Looking for a propane generator that’s quiet? We put a ton of effort into making this research guide to help you make the right choice.

1. Honda EU3000IS1A Gasoline Portable Inverter Generator

Are you on the lookout for a generator that uses inverter technology and is ultra-quiet at the same time? Honda EU3000IS1A might fit the bill.

This is one of the quietest models on my list and generates only about 49 to 58 dB.

It can operate a wide variety of appliances including a furnace, fridge, microwave, TV, blenders, most 13,500 BTU RV AC units and much more making it ideal for use at home or camping.

It is pretty fuel-efficient and can run up to 20 hours on 3.4 gallons of fuel. The tank size is about twice the size of the Generac GP3000i Super Quiet Inverter Generator. Depending on the load it runs 7.2 to 20 hours on a single tank. The oil alert helps shut off the engine as soon as the amount of oil falls to a minimum.

Another thing that I quite like about it is that it provides stable and clean power. Hence, you don’t need to worry about the safety of computers and other sensitive equipment.

The product is backed by a 3-year residential and commercial warranty.

It isn’t all good though.

For starters, the weight seems to be a little bit on the higher side, thus making it not-so-portable. The lack of wheels and handles means you would have to put an extra effort into moving around the generator.

Also, the maximum power is somewhat limited due to the Eco-Throttle technology.

Despite having a few minor flaws, the positive points easily outweigh the negatives. With superior build-quality and ultra-quiet nature (49-58 dB), the Honda EU3000IS1A is an absolute no-brainer.


  • Ultra-quiet
  • Can operate a variety of appliances
  • Provides stable and clean power
  • Low oil alert


  • Somewhat bulky
  • Maximum power is limited by the Eco-Throttle

2. Generac GP3000i Super Quiet Inverter Generator

Looking for an inverter generator that is portable at the same time? Generac GP3000i is might be what you’re looking for.

It operates fairly quietly and generates about 58 dBA at its peak.

It has got an extra edge over many other products of its type due to the advanced PowerRush technology that delivers over 50% more starting capacity. You can also connect 2 units together to double the overall power. The convenient RV-ready outlets facilitate easy connection.

The start/run/stop options are all encapsulated in the PowerDial.

I particularly like the USB outlets.

You can charge your smartphones, tablets, and other electronics with it.

In terms of portability, this is one of the best models. It’s light-weight, compact, and is furnished with a built-in handle which makes it extremely easy to carry it to any desired location.

The tank capacity is 1.06 gallons and the run time is 5.8 hours on 25% load.

Now coming to the downsides…

The run-time, while perfectly acceptable, is a bit low compared to the other recommended products on this list. Users also mentioned that they would have certainly appreciated a larger fuel tank.

Nevertheless, the product is still a great choice, especially if you’re looking for an ultra-quiet portable inverter generator.


  • Portable and Compact
  • Uses advanced PowerRush technology
  • Parallel ready
  • USB outlets


  • Average run-time
  • Average fuel tank size

It also has a low oil shut off feature. The cast iron sleeve makes it durable. The wheels and handles help to carry it to any desired location easily.

The product is backed by a 3-year limited warranty.

It comes with its own fair share of flaws though.

Firstly, it does not have a parallel capability. This means you won’t be able to harness the power of multiple generators. If having a parallel capability is a must, I’d recommend you to check Generac GP3000i Super Quiet Inverter Generator.

The tank size is average, though perfectly acceptable. While I haven’t had this issue, a few users also reported that at times it vibrates and creates quite a bit of extra noise. In most cases, this should be faulty hardware and you can often make do with a free replacement.

Overall, the Champion RV ready portable inverter generator stands true to its name and is a great pick.


  • Wireless remote start
  • Quiet operation (58dB)
  • Provides clean power
  • Portable

A convenient luggage-style telescoping handle and durable 6″ solid wheels make it easy to move the generator to the desired location very easily.

It’s not all fairytales though.

For starters, it lacks an electric start. While it does come with parallel connectivity support, the unit itself doesn’t include a parallel cable. It’s hardly a problem though, as you can easily find a parallel cable online.

All-in-all, the Briggs & Stratton P3000 is a great manual start inverter generator and one that I’d recommend.


  • Portable
  • Parallel ready
  • quiet operation
  • Low oil shutdown


  • Lacks an electric start

  • Portable
  • Extremely powerful
  • High run time
  • Large fuel tank size


  • No push-button electric start
  • A bit noisier than competitors

The Buying Guide: Factors to Consider While Purchasing the Product

1. Power of the Motor

This is one of the first things to look for in order to get a satisfactory output. The power that is delivered by the motor is expected to be stable and clean so that all the appliances are completely safe and don’t get damaged due to fluctuations.

The best way to gauge the power of the motor is to look for the run time of the system at 25% and 50% load before the fuel completely depletes. Comparing it with multiple other products can give a great idea about the product that you should go for.

Also, the products that have a 4-stroke OHV engines supply more power.

Thus, if you have to deal with lots of appliances and are looking for longer run time, then, in my opinion, the best product from the list would be Westinghouse WGen3600 Portable Generator.

2. Noise Level

Of course, none of us would like to have a generator that emits excruciating noise every time we use it, especially during camping. It would simply hamper your concentration and peace. To curtail it, you may have to put a lot of effort into soundproofing it which will not only add to the cost but will also be cumbersome.

To prevent such nasty situations, all you need to do is check the decibels of the noise it generates. Also, some generators are capable of determining the amount of power required and automatically adjusts to run slow when not much output is needed.

This feature helps in keeping the amount of noise emitted in check. Among the aforementioned products, one of the quietest models is Honda EU3000IS1A Gasoline Portable Inverter Generator.

Traditional Generators vs Inverter Generators

When it comes to noise emitted by a set, inverter generators are known to outweigh traditional generators very easily.

This is so because the mechanism used in traditional generators is such that they tend to emit a tremendous amount of sound when in use. On the other hand, the inverter generators use the latest technologies that significantly cut off many decibels of sound and run much quieter.

Generally, the conventional models produce about 65 to 75 decibels of noise, whereas the inverter ones tend to produce only 55 to 60 decibels of noise.

3. Control System

However reputed the product might be, if it cannot be used easily then there is not much point in going for it. Thus, when you make a decision, it is highly advised to check whether the product has a solid control system.

It is preferred to go for the ones that have all the operations for controlling the system in a single slot. It must be easily identifiable too.

Further, a user-friendly model must contain multiple options for starting the system. Hence, it must contain recoil start as well as options for electric start.

A number of AC and DC outlets must also be included to facilitate smooth charging. One such product that suffices most of these demands is Champion RV Ready Portable Inverter Generator. Its Quick Touch Panel makes it stand out of the lot.

In this light, Honda EU3000IS1A Gasoline Portable Inverter Generator is unmatched. It has the longest operating time of 20 hours on a single 3.4-gallon tank.

5. Portability

Generators are often required at various places like job sites, homes, camping sites, and many more. Hence, if you’re looking for such a varied use-case, you should look for the features that facilitate portability.

Thus, you must always try to get a model that is light in weight, has a compact design, and has built-in handles and wheels. These features will help you move them to the desired site effortlessly.

Of the many products mentioned in this article, Champion RV Ready Portable Inverter Generator is worth citing in this regard.
