Best Propane Generators: More power & less Toxic Emissions

The first thing that comes to many people when selecting a generator is what type of fuel is best to burn. Generators run on various fuel sources like gasoline, natural gas, solar energy, diesel, and propane. Each generator type and fuel source has its advantages and disadvantages. So, it is suggested to select any generator wisely.

If we talk about propane, then it is the best option of all. Propane and propane generators have various benefits. Propane keeps the environment clean. It is easier to access during natural disasters like hurricanes, tornadoes, and earthquakes. Also, you can store as many propane tanks as possible for a more extended period.

Buyer’s Guide

What to look at when buying the best propane generator? Here we are going to discuss all those important features that you must not miss out on at the time of purchase.

Wattage and Power Needs

The most important thing to consider before buying a generator is its wattage and your power needs. You must buy a propane generator that will meet your power needs. You must look for a generator that will meet your running wattage needs and not starting wattage requirements. This way, you can save some money on initial purchase cost; repair, and maintenance costs in the long run. Let’s look at a power demand chart to understand the starting and running power needs concept.

Appliances Starting Wattage Running Wattage
Refrigerator 1400 300
1/2 HP Furnace 2350 875
TV 400 400
Lights 200 200
AC 1800 1200
Total 6150 2975

The data above explains that to run all the applications simultaneously, you need 2975 watts of power. However, to start them all at one time, you need 6150 watts. You can manage this by adding load one by one on the generator. In this example, a generator with a running wattage of 3200 watts will be perfect. We suggest that you keep an extra cushion of 200-300 running watts when selecting your generator. A smaller generator is not only cheap to buy; running and maintenance costs are also low. You can use the above specimen to calculate power needs for your camping, RV, or work generators.

Inverter vs. Conventional Generator

First, decide whether you want an inverter generator or a conventional one. Inverter units produce clean and stable power with little or no harmonic distortion, whereas most conventional generators fail to provide clean power. Inverter generators are lightweight and compact and make less noise, whereas conventional generators are more significant in size and make noise accordingly. Also, inverter generators have smaller fuel tanks. On the other hand, conventional generators are significant, but here we are talking about propane generators, so fuel tanks will not be considered different. But inverter units are more fuel-efficient so you will get a reasonable runtime.

In a nutshell, if you need more power and your only aim is to power your home or RV appliances, then use a conventional one. Or, if you are looking for a propane generator to power your campsites and tailgate parties, then go for a compact inverter generator.

Start System

Make sure you will buy a generator with an electric start system to turn on the unit without any effort quickly. Recoil start generators are now a past thing, but still, some generators feature only a recoil start systems or add this system as a second option.

Some units come with a remote start function that gives additional comfort and relief.

Power Outlets

Before selecting a generator, make sure your unit has all the power outlets that you need. Two household outlets are standard, but four will allow you to plug other small electronics as well. Also, an RV-ready outlet is a must to use your generator with an RV anytime. Also, a 12V DC outlet will be a plus.


It would help if you also focused on the safety features of your generator. Low-oil shutoff and overload protection are quite common. Low-oil shutdown turns off the engine when the oil levels go incredibly down, and overload protection keeps the generator free from overload damages. But some units come with surge prevention to keep your sensitive electronics free from any harm.

Control Panel

A user-friendly generator will give you maximum options on the control panel. A well-equipped control panel increases the functionality of the generator. A control panel usually has a control button, display, light indicators, choke, and other operating parameters.


Look for a generator that offers maximum portability options. Features such as wheels carry handles and lifting hooks add versatility to the generator and increase portability. A lifting hook makes it easy to lift the generator with a crane.

Noise Level

All generators make some noise, and it can get pretty irritating when you have to listen to it for a night or during work. Inverters have a low noise rating compared to conventional generators. It would help if you looked for a generator with the lowest noise rating.


Always try to keep things under your budget range. You would also need to buy a generator cover or other accessories for a generator. Hence, it is better to stay on budget and don’t overspend. However, you must not compromise on the generator’s quality.

Warranty and Certifications

Warranty and certifications add value to your generator. When your generator is in the warranty period, you don’t have to worry about repairs and faults. The standard warranty period is 1-3 years. Some brands offer up to 5 years of warranty. Make sure you take a look at the terms and conditions of the warranty before buying and using your generator. Certifications from EPA and other regulatory bodies ensure that your generator is safe for the environment and results in a better working experience.

Propane vs. Gas Generators

Gas generators have been the go-to generator for millions of people. However, propane generators are now becoming famous day by day. A propane generator may give you less output, but it burns cleaner than gas and keeps the surroundings and environment clean. Propane is cheaper than gas and has a longer shelf life. It is also safe to store. Gas is readily available compared to Propane, but its availability comes into question at times of natural disasters. Burning Propane will not emit toxic fumes and smell like gas; hence it is safe for kids and smell-sensitive folks.


What are the advantages of propane generators?

  • Propane generators have various benefits that are as under.
  • Propane gas has a longer shelf life. You can store propane tanks for many years to come.
  • During natural disasters, Propane is more comfortable to access.
  • Propane is a clean-burning fuel.
  • Propane is non-toxic.
  • Propane generators need less maintenance.
  • You can run propane generators as long as you want.

Which is the best one to use? Propane inverter generator or propane conventional generator

It depends on your needs. If you need more power output, go for a conventional generator, and if you need less power output, then inverter generators are best for you. If you are going to buy a propane generator to run at campsites or tailgates, select small and portable generators. On the other hand, to power, your house, go for a conventional generator.

How loud are propane generators?

Propane doesn’t affect the noise level, but the inverter and conventional generators do. Inverter units make less noise than conventional ones, so if you need a peaceful environment at campsites or during a power outage, go for an inverter generator; otherwise, conventional generators are there with higher decibel ratings you can place at some distance.

Is a propane generator better than a gas generator?

The answer to this question depends on several factors. If you are looking for more power, then a propane generator is not your thing. Its burning capability is less than gasoline. However, for all the environment-caring people out there, Propane is best. It burns cleaner, doesn’t emit harmful gases, and leaves low-carbon residue in the generator. It, in turn, reduces your maintenance or repair costs. When it comes to fuel availability in emergencies and storage, a propane generator is a clear winner.

How much Propane will my generator use in 1 hour?

There is no definite answer to this question. It depends on the power of your unit and the load on it. To conserve Propane, keep the running load around 50% of the total running watts.

What are the limitations of a propane-powered generator?

Arranging Propane is a bit difficult. If you can’t get propane cylinders delivered, you will have to travel miles to get hold of Propane as propane vendors are often located outside the city. The overall life of a propane generator is less than that a gasoline generator. Propane has less energy density, which means that it will not give a high power rating like gasoline or diesel generators.

Do I need a transfer switch with a propane generator?

Yes. A transfer switch connects the generator safely to your home panel. Skipping the transfer switch is an open invitation for electrical hazards.

Should I go for a propane generator or a dual fuel generator?

A dual-fuel generator is the best of both worlds (Propane and gas). It gives you versatility as you have the freedom to run the generator on two fuels. Dual-fuel generators are a bit more costly as compared to single-fuel generators.

Final Words

A propane generator will keep your home illuminated during a power outage. It will also keep you away from the hassle of storing highly flammable gasoline. You can select a propane generator from the list above and forget the tension of staying in the dark.
