Generators are an excellent investment for so many different reasons. They can be a life-saver if you have a power cut, and similarly, allow you access to electricity while you are out on camping holidays.
But there is one thing that can be incredibly frustrating about generators, and that is the noise that they produce.
Generators can be notoriously loud, and you hear endless stories of neighbors complaining about noisy generators. Thankfully, manufacturers have started to notice this dislike for noise and have begun to produce much quieter generators.
As quiet generators are still in their infancy, it can be difficult to find the perfect one for you. But there’s no need to worry because we’ve put together this guide to the 10 best quietest generators on the market, ranking the generators from the quietest to the slightly louder options.
So if you’re looking for a generator and noise is a big concern for you, you’re in the right place!

Best Quietest Generators Buying Guide
Finding the perfect generator for you can be difficult, especially when there are so many excellent options available.
The generators that we have looked at above are some of the quietest on the market but if you are still uncertain whether or not they are the right option for you, we’ve put together this buyer’s guide to help.
We’ve included absolutely everything that you need to know not only about quietness in generators but about other factors that you need to consider. So if you need to find out more before you purchase your generator, then you are in the right place.
As you are looking for a quiet generator, the most important thing that you need to consider when making a purchase is operating noise.
The majority of manufacturers will openly state the operating noise of their generator, especially if they have produced this specific design with quietness in mind.
However, the manufacturers of portable generators are not legally obliged to state the operating noise of their generators and so some companies will not give a specific number.
Operating noise is measured in decibels, and it is not only used to measure the noise of generators but general noise too. Due to this, you can get a general idea of how noisy a generator will be by comparing it to something else.
The average conversation usually measures 60 decibels, so ideally you want to choose a generator that measures somewhere around this level. However, some larger generators will significantly exceed this noise level so you should bear this in mind when you are making a purchase.
Another very important thing that you need to consider when purchasing a generator is how powerful the generator is going to be.
If you are purchasing a generator, you are probably doing so with a specific function in mind so you must purchase a generator that can produce enough power for the devices you are wanting to run.
All generators will come with two power ratings: running power and surge power. The running power is the amount of electricity that the generator will be able to continuously supply, while the surge power will be the amount that it can supply for a very short period, ie. when an electric drill is starting up.
The most important measurement is the running power as this is what will supply electricity to your devices.
To ensure you are buying a generator that is capable of running all of the devices that you want it to operate, you should add up the running power required for all of the devices and purchase a generator that can produce 20% more power than this number.
Something else that you should consider which may or may not be important for you is portability.
If you are planning on using a generator to provide electricity to your home then this will not be important. But if you want a generator that you can take on the go with you then portability is very important.
Portability dictates how easily you will be able to transport the generator and is influenced by lots of different things including the physical size and weight of the design, as well as any additional features added to the design to make it easier to transport, such as wheels or a handle.
The more portable generators tend to be the products that have a smaller electrical capacity, so you must consider whether power or portability is more important to you before you make a purchase.
Finally, you need to consider the fuel type of the generator that you are thinking of buying. The more powerful generators tend to be operated on either gasoline, diesel, or propane.
However, some of the smaller and more portable generators are now starting to operate on a battery that is rechargeable via solar panels.
But let’s focus on the traditional types of generators. Diesel generators have become rare in recent years due to the large focus on being eco-friendly so a lot of people are choosing other options rather than diesel.
The majority of people choose to buy generators that run on either propane or gasoline, and some even choose to buy generators that can operate on either gasoline or propane depending on what you have access to.
All of the different fuel types have their benefits and their downfalls, for example, propane is a clean fuel so it is good for the environment but it reduces the number of hours that the generator can operate for.
So you need to weigh up the pros and cons of the different types before you make a purchase.
Frequently Asked Questions
How far should a generator be from the house?
There is a lot of confusion about where you should store your generator. A lot of people know that you have to keep your generator a certain distance from your home, but most people don’t actually know how far this distance is.
When you are using your generator the most important number to remember is 20 feet as your generator should always be stored at least 20 feet from your home when it is in use. The engine exhaust of the generator should also be stored facing away from your home for total safety.
Can you leave a generator on overnight?
In short, the answer is yes, you can run a generator overnight. This is, of course, only possible if your generator is designed to run for long periods of time and preferably for more than 8 hours.
The time of the day that you are running the generator does not impact its ability, however, if your generator is not designed to run for more than a handful of hours then the chances are that it will die during the night.
Is 70 decibels loud?
Decibels are the measurement used to dictate how loud a certain sound is. This measurement is quite a funny one as a number that might appear high in normal circumstances, usually matches to a low noise level.
For example, a quiet whisper usually measures around 30 decibels, and a normal conversation can measure anywhere between 60 and 70 decibels. It is once the noise exceeds 70 decibels that it becomes considered loud and could put your hearing at risk.
