Propane generators are useful pieces of equipment to have for emergency backups, and outdoor activities like camping, or RVs. They are typically environmentally friendly as they produce fewer emissions and are non-toxic. Propane generators only require refilling and don’t need electricity to power, making them useful when you run out of power and saving fuel costs.

The key reason for them being preferred in comparison with other generators that run on fuel or diesel is because they are generally a lot quieter. These generators are very convenient for users as they permit you will to not disturb your neighbors with the noise when running.

Generally, most of them have noise levels ranging from 47 to 76 decibels. However, as you should already know, the lower the decibel, doesn’t necessarily equate to the lesser the noise.

The amount of noise a generator produces will depend significantly on its mechanism and the conditions in which it is used. There are many types of generators in the market. This article will provide you a buying guide and a review of the quietest propane generator in the market.

Quiet Propane Generator Buying Guide

Before presenting all the various quiet propane generator reviews, let’s take a look at some of the basic features that you’ll want to understand and be able to compare.

If you keep the following quiet propane generator features in mind, you should be in a great position to choose a small quiet propane generator that suits your needs.

Types of Generators

So, why a super quiet propane generator? And, what other types of generators are they competing with? There are a few types of quiet generators that you should consider if you haven’t already, and they can generally be classed into different fuel types.

Fuel Type

Although generators have traditionally run on propane, they’re not the only fuel compatibility you will come across on the market. Even if you have no interest in the other fuel types, it’s important to be aware of them. Most quiet generators either run on propane or natural gas, but you will be able to find some diesel generators as well.

Propane Generators

Propane generators are certainly the most popular generator fuel type and for good reason. While propane is more expensive than natural gas, it has a higher energy density, allowing it to last fairly longer in comparison. Propane generators are also far more widely available, so it may be that you can only find propane generators in your local stores. 

Natural Gas Generators

Natural gas is a cheaper alternative to propane, but unfortunately, it doesn’t last as long. However, the cost savings will be significant, with natural gas generally selling for around 40% less than propane. If you already have a natural gas line running under your property, this may very well be the best option for you. 

Diesel Generators

You might come across some specialized diesel generators. They require a liquid-cooled housing unit that tends to be more reliable than propane or natural gas. However, they tend to be far more expensive to install, and then you have the recurring cost of diesel, which in today’s market is costing more and more.  

Dual Fuel Generators

Many of the generators we have described on this list are what are typically known as “dual fuel” generators. Dual fuel means you can use gasoline or propane as the generator’s fuel source. 

While most of these dual fuel generators will require you to use the fuel you loaded up before starting the generator, some of them may allow you to switch fuel sources while in operation. This can be fantastic if you run out of gasoline but have some propane loaded into the fuel tank, as you can switch fuel without shutting your generator down. 

Generator Runtimes

The next important factor that you will need to keep in mind is the runtime of your generator. This will essentially be the number of hours that your generator can run at once. For powering your entire house, you should go for one that can provide at least 10-12 hours of running time.

For RV applications, you’ll usually need the power in specific intervals rather than the whole time. However, you should still aim for one with at least 6-8 hours of runtime to not have to worry and for the best results.

Note: it’s important to remember that runtime is usually calculated at fifty percent load. Therefore, the usage to which you put your generator will also play a role in this.

Size

The size is always a big concern for buyers looking for the best quiet propane generator. You may initially think that big and bulky generators will generally run louder than smaller ones, and in most cases, you’d be right.

However, many larger generators that have become available in recent years are generally much quieter than their older counterparts. Also, small generators are capable of packing a powerful punch, so don’t disregard a generator solely based on its size.

Wattage/Power Output

The wattage/power output of the quiet propane generator is one of the most important specifications you need to consider. Basically, the number of watts your generator is capable of providing will determine how many devices and appliances you can plug in at one time and power. 

For example, a 2000W propane generator will be able to handle more than a 1600W natural gas generator. As a result, you will be able to run more devices. Each and every generator will have a power output limit, regardless of whether it is hooked up directly via a manual transfer switch.

What Do You Need the Generator to Do?

Aside from a quiet propane generator’s design specifications, you will need to think about what you actually want to get out of your generator. Think about it, two different generators might have similar power outputs, but one may be lighter and therefore be easier to move than the other.

Noise Level

If you’re reading this article, chances are already that the noise levels are a big priority for you. Noise levels can be impacted by a wide range of factors, including wattage, fuel type, size, and the generator’s exhaust mechanism.

With modern-day technology consistently advancing, propane generators are becoming quieter and quieter by the year, but there are still so many that are far louder than the quietest propane generator on the market. 

Be vigilant and check the generator’s product manual for its noise specifications, if it has any. You’ll often find a decibel level listed, however, not all brands have measured their products for noise level. Therefore, pay attention to customer reviews as these can always be a useful depiction of how quiet a propane generator is, from users alike!

Portability

Another essential thing to consider is the portability of your generator. If you only want a generator for when the power might go out in your home, then portability might not be a big issue for you as it will primarily be stood on standby. 

However, if you do plan on using your generator at worksites or various outdoor areas, then you need to think about how easy it is to move from one place to another. Some propane generators will be a lot smaller and may have handles and wheels attached to help with transport, while others are relatively fixed in place and can be difficult to move so frequently. 

You must always consider whether you’re going to need to move the propane generator to different places before you decide on the brand you wish to purchase from. Will you be going upstairs or across a rocky driveway? You’ll need handles or some durable wheels.

Tip: You never know where you’ll need to take your generator, so it’s always better to be prepared than not. 

Safety Factors

At the end of the day, a generator is an electromechanical device that can pose serious safety concerns. When choosing the right propane generator, go with models that feature low-oil alert and auto-shutoff features.

And better still, make sure that your device of choice has a surge protection mechanism built in to protect sensitive electronics from potential damage.

How Big is Your Budget?

Let’s be honest with ourselves, our budget is going to strongly determine the quality and brand of the generator you’re able to purchase. But, the more expensive generators aren’t necessarily better, although that is a pretty good rule of thumb to go by. 

Depending on how much you are willing to invest in your quiet propane generator, there is a large range of low-budget and high-budget propane generators available on the market. Figure out how much you want to spend before you start looking, and you’ll get a good idea of what options are out there for you. 

Low Budget Propane Generators

The cheaper propane generators will typically have a far shorter runtime than the more expensive options. You may only get 6-8 hours of use out of your budget generator compared to 14-16 hours from a far more expensive brand. 

Also, the cheaper propane generators are often louder than more expensive models. If the primary reason you’re reading this article is to find the quietest propane generator, I can assure you that it won’t be the cheapest you find. 

However, these low-budget generators do have some benefits. The cheaper generators will typically weigh far less than expensive models due to having far fewer components. They might also be more maneuverable and portable, simply because they will be smaller and weigh less in comparison. 

High Budget Propane Generators

High-budget propane generators will tend to be much more capable than the low-budget models, providing you with more and quieter runtime. Not only that, but you may even save money in the long run if you spend more at the start.

High-end generators will often be more fuel-efficient than the budget models and also last a lot longer. You won’t have to replace your generator so soon, and you won’t be spending as much money on propane to run the machine. You get what you pay for!

High-budget generator accessories will be of a higher quality as well. Therefore, your wheels won’t break, your handles won’t snap, and the generator certainly won’t knock out on you for no apparent reason. 

Top Brands to Look Out For
