Best 6 Quietest Portable Generators On The Market

Generators are a good thing to have especially when a utility power outage threatens to go for several days or weeks.

The major challenge, however, is that these gadgets can’t generate power without emitting noise. If you live in a neighborhood with strict regulations with regard to noise pollution, then a silent generator becomes a MUST.

In the past few decades, generator manufacturers have developed technologies that maximize power output while keeping the noise level as low as possible.

This article brings some of the quietest portable generators for use at home and in your outdoor adventures: camping, tailgating, caravanning, and boating. We’ve also put together a buying guide to help you select the best quiet generator for your needs.

Our Top Picks

How to Choose the Best Quiet Portable Generator

It goes without saying that the very first consideration when choosing a low noise generator will be its noise decibel rating. Although not a requirement, almost all manufacturers will indicate this somewhere in the specs sheet.

Most of the silent generators that we’ve come across so far range between mid-40 dBA and 60 dBA. The lower the value, the quieter the generator.

Be careful when comparing these ratings, though, as different manufacturers will indicate the noise level of the generator at different load capacities. For instance, generator A may be 42 dBA loud at 25% load and generator B 57 dBA loud at full load. Since the noise level correlates with engine speed and power output, generator A is likely to be louder than B at full load. So, for an apples-to-apples comparison, compare the dBA ratings at equal load capacities.

Now, while silent operations may be a prerequisite in camping sites and in your neighborhood, remember that what you need most is power. So, as you gravitate towards the best quiet portable generator on the market, be sure to get a model that outputs enough power for your load.

That’s to say that you need to add the wattage requirements of all the appliances that you’ll want to power simultaneously first, and then identify the generator that meets that power demand.

What Makes a Generator Noisy

There are several factors that impact on the noise level of a generator, the obvious one being its size. More often than not, big generators tend to be louder than their smaller counterparts partly because the formers are fitted with bigger engines that output more power as well as more noise.

It’s good to mention that the sound of any engine is energy wasted in the form of heat and noise, and the ratio of power to noise tends to get higher with the size of the engine. It’s undeniable that manufacturers are keen to make their engines more efficient, but there’s always a limit to how efficient an engine of any size can get. This, therefore, means that powerful engines are more likely to produce more noise.

On the same note, keep in mind that noise in generators is mostly caused by the vibrations of the moving parts. So, it follows that everything else held constant, a bigger engine vibrates more thereby leading to more noise.

The fans that are intended to cool down the engine also tend to get louder with an increase in operating speed and this also adds to the overall sound of the generator.

Understanding Noise Decibels (dBA) in Portable Generators

Decibel metrics are usually an indication of how loud or quiet a generator is. In portable generators, this can range from 45 dBA to 110 dBA.

Generator manufacturers usually measure their engine’s noise level from a distance of approximately 7 feet. So, to ensure that you get the quietest generator, compare models with ratings that have been taken from the same distance.

It’s important to note that the difference in decibel ratings is more than just the numbers. As a matter of fact, a 10-decibel difference makes one model 2x louder than another generator. Therefore, it follows that a mere 2-decibel difference could have a significant impact on the loudness of a generator and its effects on other people in the camping site or your neighbors.

Important Considerations and Features When Purchasing a Quiet Generator

Noise

Since you are after a quiet generator, the noise level should automatically be at the top of your checklist. There isn’t a universal limit on how loud a generator should be. But generally, generators operating at between 40 dBA and 60 dBA are considered the best in terms of low noise performance.

Ease of mobility

Most quiet running generators are engineered with portability in mind. But they differ a lot in terms of ease of mobility. The weight of the generator greatly impacts how you’ll be able to lift and move it around. That being the case, check out the configuration of the handles and whether your target model has a wheelbase.

Runtime (a.k.a efficiency)

Runtime refers to how long the generator can run steadily per tankful at a given load capacity. This also talks volumes about its fuel economy (a.k.a efficiency) and how often you’ll need to refill the tank. Note that runtime is expressed depending on the load. For instance, generator A could offer you 8 hours of runtime at 25% load, and generator B 10 hours at the same load. What matters most, however, is the power output of each generator and the size of the fuel tank. Generally, you want a generator that offers the highest power possible from every gallon of fuel.

Go for a Reputable Brand

You want a low noise generator that will pull through nicely throughout the emergency period and offer you a nice time during your outdoor escapades. Believe us, the last thing that you want is to grab your generator from the garage after a storm only for it not to power up as expected. That being said, it’s always advisable to deal with reputable brands. Quiet generators from renowned brands could be expensive at first. But they really pay for themselves in terms of reliability and durability. It’s also much easier to get their replacement parts and customer service than it would be the case with newer brands.

 

Frequently Asked Questions

How can I make a generator quiet?

There is a plentitude of options here. The most straightforward remedy is to replace the muffler with a bigger one. You could also soundproof the generator by placing it on a rubber board or feet to minimize the vibrations. Installing a sound deflector- an object that changes the path of the sound away from you- is another option too although it does not make the generator itself any less noisy.

How quiet should a generator be?

There isn’t a standardized decibel rating for quiet generators but those below 60 decibels are less likely to irritate your neighbors and other campers.

What makes inverter generators so quiet?

First, it has to do with their small engines that also tend to limit their maximum power output. Inverters are also crafted with modern technology that works exceptionally in dampening sound. Another reason is that these generators are designed to adjust the speed according to the load. The lower the wattage demand, the quieter the engine.

How much do quiet generators cost?

Generators made with inverter technology are generally the best in terms of low noise output. But this technology also makes them quite pricier than conventional generators in similar power ranges. The increase in demand for inverter generators has led to the rise of newer brands that offer much lower price tags, though.

Conclusion

Manufacturers are in a constant race to make a super quiet generator that is both efficient and reliable. Our quiet generator reviews aim to help you find the best model that fits your needs.
