Benefits and Drawbacks of Propane as Generator Fuel Source

When shopping for a new generator, the variety of fuel options can be overwhelming. Propane, a type of liquefied petroleum gas (LPG), is one of the most popular fuels for generators.

Diesel, gasoline, LPG, and natural gas are some of the more popular fuel options. You may be wondering which fuel source is the most efficient.

The response is highly dependent on your specific needs and desires. Diesel engines, for example, have the greatest energy efficiency of all types fuel, requiring the least volume of fuel per kWh.

Diesel is best for high-output generators for this purpose, among others. On the other side, propane is cleaner than diesel and needs no refueling trips to the pump. You can find propane easily at hardware stores, convenience stores & gas stations.

Propane has its own set of advantages and drawbacks that users should be aware of before investing in a generator that runs on it.

N.B.: It is a good idea to not use propane inside as carbon monoxide (CO) poisoning can be fatal.

What to Consider When Choosing the Best Propane Generator

Wattage Needs

Generators are advertised based on their wattage, which is measured in watts (W) and kW. If you want to use propane powered generators to run your whole house in an emergency, you can look for a high-powered generator models with a minimum output of 5,000 watts, and even more if you have electrical appliances like a sump pump or an energy-hungry systems like a refrigerator, an air-conditioning system or other larger electrical appliances.

A smaller generator with just 3,000 Watt, on the other hand, may be sufficient if you are attempting to power an RV or a campsite.

If you choose to run your generator solely on propane rather than gasoline, make sure to factor in how much power the generator will output on propane instead of gasoline.

Make a list of everything you don’t want to run when the power is down, and count up their watts to provide a rough estimate. Here are some rough estimates for common necessities:

  • Refrigerator: 600 – 1200 Watts
  • Sump Pump: 1000 Watts
  • Microwave Oven: 1000 Watts
  • Television: 300 Watts
  • Coffeemaker: 900 Watts
  • Window Air Conditioner: 1,000 Watts
  • Lights: 200 To 100 Watts

You would need a generator with a long period of 10-12 hours, at half power if you are preparing to power your house and want everything to run near normal.

However, if you are driving an RV and only require power for a few minutes, runtime might not be a significant concern. Here is our recommendation by wattage is below:

Conventional vs. Inverter generator

Most generator concerns arise from customers purchasing their needs as the wrong model.

Before making the final choice, it is important to think carefully about what you want to power. Conventional and inverter generators provide the AC energy, but the system is so different that the way traditional and inverter generators work in operation varies significantly.

Usually, the inverter generators are more compact, portable and quieter than conventional generators.

However, this also implies that these small generators normally have less energy-efficient fuel tanks as well as lower outputs and therefore a shorter runtime.

But inverter generators can be run in parallel to maximize the power output, while conventional generators are limited to whatever wattage they are designed for.

Automatic or Electric Start

“Electric start” is becoming a more prevalent and popular feature on generators.

Electric start generators are very easy to start, involving very little of the fuss that has traditionally accompanied generators.

Some units also have a remote start feature, which is ideal for RV use because it allows you to switch on the power without having to go outside in the morning. Your user interface is heavily influenced by how easy the unit is to start.

The disadvantage of the electric starter is that it would not work if the generator’s battery has been depleted.

A ripcord or pull cord is used in the recoil models. They resemble those used on a lawnmower. These generators don’t use battery power to work, and they’re normally less expensive than electric start models.

The cord starter has the disadvantage of requiring more effort. It could take a couple of pulls to get it going.

Fuel Gauge And Readings

Portable generators with less features are normally less costly. Expensive models usually have LCD screens that have a complete readout of various settings. Smart generator models which connect to an app are also available.

These features are intriguing, but they aren’t required. What you really need is a gauge to tell about how much propane is left. Some models have a meter that indicates how many levels are left. Others just have a lamp that turns on as the fuel runs out.

Propane generators require a certain amount of pressure in propane tanks to run. Any type of gauge is beneficial. Simply make sure that the model you purchase has some kind of predictor. If it doesn’t, have extra tanks on hand at all times.

Portability & Wheels

Some generators weigh about 100 pounds and come with sturdy wheels, more powerful generators and tri-fuel models can often weigh over 200 pounds and be difficult to move even with wheels.

Although Small generators are more portable, without wheels, even these small units will easily become cumbersome. Consider how much you need to switch your generator if you want to get it in place for the long term.

The more powerful or generative it is, the more weight it has. A model with 11,000 watts, for example, could weigh 300 pounds. Weight is less of a problem if you’re using the generator to power your home, since you won’t be carrying the generator around very much.

Weight becomes a major consideration if you need power when tailgating or camping. Thankfully, you don’t have that many needs when camping and tailgating as when running a home. A small, portable generator should have enough power to meet your needs.


By distributing the load around four or more people, you can get the most out of the wattage. When buying a generator, look for a number of outlets.

Many newer models have a 30-amp RV ready outlet, which can be extremely useful if you choose to use your generator with an RV. Furthermore, while many generators only have two regular AC outlets, having four or more will open up space by allowing you to plug in several small electronics.

Safety & Auto Shut Off

In addition to the fuel level indicator, an oil level indicator is also useful. You risk damaging your machine’s motor if it runs out of oil. The generator shuts down if the oil level falls below a certain threshold or the engine overheats, preventing engine damage.

It’s usually only seen on stationary generators, but it’s becoming more popular on portables.
Surge protection is available on some generators, which protects delicate electronics such as laptops from being fried and reduces the chance of electrocution when plugging into the generator.


You’ll be paying a couple hundred bucks for a propane generator, so look for a warranty that lasts for the long term. One or two years is the industry norm.

The warranty on the Duromax XP4850EH portable generator, for instance, includes components but not labour. It’s easy to swap a part or two if you’re handy with machinery. Otherwise, you’ll need to look for a model that comes with a labour warranty.
