Best Propane Generator: Reviews and Buying Guide

You may have already done your homework on propane vs. gas generators and concluded that, for your specific needs, a propane generator is better than a gas generator.

Many homeowners stand by propane generators, despite the fact that they are notoriously less cost-effective than their gas-powered counterparts.

Propane generators are designed to start automatically, depending on their power output. It can help you restore power to your most vital appliances or perhaps your complete home.

Running 100-foot extension wires across the lawn while stealing your neighbor’s power is no more necessary thanks to a backup propane generator.

Power outages have the potential to put food in the refrigerator at risk of spoiling and to create potentially fatal conditions in cold weather.

A strong propane generator can provide enough energy to run a space heater or air conditioner, keep the lights on, and preserve food in the refrigerator.

Additionally, portable propane generators provide energy to off-grid locations like campgrounds.

Propane doesn’t break down as gasoline does, making it simple to maintain a stock of propane tanks.

The ideal moment to purchase a standby propane generator was yesterday.

Today is the next ideal time. Having said all this, let’s dive straight into what I have in store for you today.

Best Propane Generator: Overview

Since they were invented, portable generators have proven to be quite useful in case of sudden power disruptions.

They are utilized in a variety of settings outside emergencies, including buildings, RVs, camping, events, and social gatherings.

The majority of portable generators are typically either diesel- or gasoline-powered.

But lately, portable generators that run on propane (a form of LPG, or liquefied petroleum gas), are also becoming more popular.

To be fair, these propane generators operate on both gas and propane, making them dual-fuel generators.

The ideal alternative if you need a power source during a power outage or merely need energy for your electric appliances in a remote location – especially if you do not have easy access to gas stations, is to have a propane generator.

The primary benefit of propane generators over gasoline generators is that propane burns cleaner and creates less pollution (Carbon Monoxide).

So you have a generator that is good for the environment.

However, propane itself is a drawback of propane generators.

Propane is frequently offered in tanks, as opposed to gasoline or diesel, which may be conveniently acquired from gas stations.

If you intend to use it with a generator, you must purchase these tanks in advance.

Even for powering large electric appliances, propane generators are quite useful.

Best Propane Generator: Pros And Cons


Easy To Obtain Fuel In A Crisis

Many people only use their generators in an emergency because you can’t usually use a petrol station during a power outage.

Fortunately, if you decide on a propane generator, you won’t be impacted by this as propane is delivered in tanks instead of being dispersed from petrol stations. Knowing that there is less chance of running out of gasoline allows you to unwind.

The Fuel’s Shelf Life Is Long

Additionally, unlike other common options like diesel, propane doesn’t deteriorate over time, so you can keep it for a lot longer.

Many prefer that their propane doesn’t have to be used by a specific date, and with a good storage tank, you can be confident that you have adequate fuel for any conceivable circumstance.

A Clean Burning Fuel

Propane is a fantastic option for the environment as well. It is renowned for burning cleanly and producing less pollution than other fuels.

If you’re concerned about your carbon impact, it is estimated that a propane generator creates half as much carbon monoxide as a gasoline generator.


For propane-powered generators, you won’t need to do some types of maintenance that are required for generators that operate on gasoline and diesel.

Your engine and exhaust need to be periodically cleaned since gasoline and diesel leave carbon deposits there.

Additionally, these fuels create residue in fuel pipes and other system components, increasing maintenance.

Since propane has none of these negative effects on engines, maintaining generators powered by propane is simpler (though not always less expensive).

Spill Free

Compared to gasoline and diesel fuel, which have storage containers without valves, propane tanks include safety valves, making them significantly less likely to leak.

While most gasoline and diesel storage containers do not retain fumes, the safety valves in the tanks do. Diesel has less evaporation than gasoline, which is significantly more volatile.

You risk losing a significant amount of gasoline if you let it spill out of its container due to evaporation.

There is no risk present even if your gas leaks from its tank. Propane is a “green” fuel when left unburned.

In contrast to gasoline and diesel, it doesn’t harm the environment.

Cold Weather

Colder temperatures cause gasoline and diesel to become more viscous, which makes them more challenging to use.

Winter conditions make it particularly difficult for diesel engines to start since they need to operate at specific temperatures to function properly.

“Wet stacking,” a condition that affects diesel engines while operating at suboptimal temperatures, can harm the engine and reduce performance.

However, propane doesn’t have these temperature-related issues.

Therefore, it makes sense for people living in places with extremely harsh winters to choose it for emergency power.

No Pipes Have Cracks.

Since the beginning, every justification has contrasted propane to diesel and gasoline. Natural gas is still unmentioned.

Propane and natural gas are comparable in many ways, including performance, safety, and emission levels.

However, one benefit of propane is its accessibility.

Unlike natural gas, which is distributed to homes and businesses through conduits, propane is kept in tanks.

Your generator won’t have fuel if these gas pipelines are damaged during a storm.

Natural gas is frequently inaccessible in rural locations, leaving only propane, LPG, diesel, and gasoline as fuel sources.


Propane offers over two times as much energy per cubic foot than natural gas.

Approximately 1,040 BTUs are provided by natural gas per cubic foot, compared to 2,490 BTUs by propane.

This implies that you’ll consume over two times as much natural gas as propane in the same amount of time.

That does not mean that propane is less expensive than natural gas.

Costs are higher. However, propane is a superior option because it can sustain you longer if running out of fuel is an issue.


The Fuel Requires A Tank

As was already noted, propane comes in tanks, so you will need to build piping connecting your new generator and the propane tank. Otherwise, you will just need to top out the fuel tank in your generator as needed.

To make sure that everything is done perfectly and nothing is missed, you will probably need to employ a professional to complete this task for you.

Less Effective Than Opposite Fuels

Although propane fuel has several evident advantages, it is less effective than other fuels.

Since propane will probably burn through considerably more quickly than gasoline, you’ll need to have a big sufficient tank for keeping your generator going in the event of a power outage.

Some generator owners may be put off by propane’s poor energy density.

Engine’s Lifespan

Regrettably, propane generators are recognized for needing more care than other options.

Even if you keep a propane generator well-maintained, you will probably need to replace it much more frequently than, say, a diesel generator. For those who are concerned about it failing when they require it most, this is a worry.

Distance To Get Tanks

Propane is less widely available than gasoline and diesel, and propane purchased from a specialized propane supplier is more expensive than propane stored in gas station tanks.

If you can’t get it delivered to your home, you’ll have to go far to reach these suppliers because they are frequently found outside of cities.

Factors To Consider When Choosing A Propane Generator


The physical size of the generator is one of the most important elements to consider when selecting the best propane generator for your house.

Your propane generator will need to be close to your home whether you have a little yard or several acres of property. So the size probably counts.

The National Fire Protection Association (NFPA) mandates a space of five feet around all residential openings, including windows and doors.

Smaller home generators may be permitted up to 18 inches from an outside wall following NFPA requirements.

However, you should always verify your local regulations since some may deviate from the NFPA guidelines.


Propane generators are commonly used as temporary power sources for lodging, structures, and entertainment.

They are excellent for use in rural locations with limited connectivity to the electrical grid or for usage off the grid.

They are only safe to use when at least 20 feet away from any exterior structures as a result of the pollutants that they create.

The majority have huge handles, wheels, or other characteristics to make them mobile because of this.

Consumption Of Fuel

To avoid running out of fuel when you need it most, you must be aware of the quantity of propane your generator will consume.

Making a fuel budget and planning will help you have adequate gasoline on hand in case of a catastrophe or emergency.

For instance, depending on the load, propane generators generally use 1.5 to 3 gallons per hour.

For eight to ten hours, a 20-gallon tank will provide backup power.

Requirements For Power

The power requirements of your house and your most vital major appliances are one of the most crucial factors to consider when buying a propane generator.

Electric water heaters, portable space heaters, medical equipment, sump or well pumps, air conditioning, and, if you live in a cold climate, sump or well pumps will likely have the biggest power consumption and be the most crucial appliances after an outage.

Many times, the makers of propane generators include an online wattage calculator that you may use to tally up all of your most important items and pick the best propane generator for your home.

You may sum up the “starting watts” given on the wattage rating labels of your most important appliances to get this figure on your own.

If the “starting watts” for your appliance are not listed, multiply the “running watts” by three. Once you’ve calculated the total beginning watts, multiply it by 1.5 to ensure there is a sufficient margin of safety.

Most propane standby or backup generators will be offered with an output of 9,000 to 20,000 watts since the usual minimum wattage for important appliances in small to medium-sized U.S. houses is 5,000 to 7,500.

Sound Level

The amount of noise the engine makes when it is producing electricity is a crucial factor to consider when selecting a propane generator. Since these generators are situated just outside of your home, you should choose a quieter model.

Although the precise noise level can vary depending on how much power the engine is producing, the majority of the generators on this list average between 60 and 70 dbA.

Since you might not want the noise immediately outside a bedroom or office window, where you put a propane generator outside your house is also crucial.

As a point of comparison, a typical conversation is around 60 dbA, whilst a vacuum cleaner emits between 70 and 80 dbA.

Safety And Exhaust

If you want to power your home affordably and sustainably, think about getting a propane generator.

You may use propane in your yard or at the campground with less concern for odors and air quality because it is a clean-burning fuel that creates far fewer particles and pollutants than gasoline.

However, you should never use a propane generator inside of a tiny, confined place since the exhaust can quickly build up with carbon monoxide. Remember that before starting to use your generator this season.

If the right safety measures aren’t done, any generator might be fatal.

Best Propane Generator: Frequently Asked Questions

1. Is there a propane only generator?

For a variety of reasons, propane generators are becoming increasingly popular. Unlike gas and diesel generators, propane generators run on an efficient, clean-burning fuel that is both renewable and cost-effective.

2. Are propane portable generators good?

Propane is an environmentally friendly fuel. Reduced emissions are not only healthier for the environment and local air quality, but propane generators usually require less maintenance, resulting in greater dependability and longer life.

3. What is the disadvantage of propane generator?

(a) Inefficient compared to alternative fuels: While propane fuel has clear advantages, it is less efficient than other fuel sources. You will most certainly burn through propane significantly faster, requiring a large enough tank to keep your generator going during a power outage. Some generator owners are put off by propane’s poor energy density.
(b) Unfortunately, propane generators are recognized for requiring more care than other choices, and even if you keep it properly maintained, you will likely need to replace a propane generator much sooner than, say, a diesel generator. This is an issue for individuals who are concerned about it failing when they need it

4. How long will a propane generator run?

Propane – This clean-burning fuel source has an infinite shelf life and is safer than gasoline, with a runtime of 150 to 200 hours.

5. How much fuel does a propane generator use per hour?
