Power outages can threaten to spoil the food in the fridge and lead to life-threatening situations in cold temperatures. Having a powerful propane generator can produce enough juice to keep the lights on, keep food in the refrigerator fresh, and power a space heater or air-conditioning unit.

Portable propane generators also bring electricity to places that are off the grid, such as campsites. Unlike gasoline, propane doesn’t degrade, so it’s easy to keep a supply of propane tanks. This guide will examine the important features and characteristics of propane generators and review some of the top models on the market.

What to Consider When Choosing the Best Propane Generator

While power output is perhaps the most important attribute of a propane generator, factors such as portability, noise level, and outlet types are also important to consider when shopping for one of these appliances.

Wattage Output

The sole purpose of a generator is to supply power when there are no conventional means of power available. They step in to fill the gap when there’s a power outage or at campgrounds with no electrical hookups. With that in mind, the output of the generator is crucial.

Generators are rated by how much wattage they produce. Most generators capable of functioning off a propane fuel tank have a wattage range of 1,800 for compact models to more than 10,000 for larger units. Most generators have two ratings: starting wattage and running wattage.

The starting wattage is the amount of power a generator can supply in short bursts. This is to account for most electrical appliances, which typically require a higher starting wattage but significantly fewer watts to run.

The total consumed wattage of most homes’ major appliances is around 5,000 watts. This is enough power to run a 600-watt refrigerator and a 1,500-watt space heater or a 1,000-watt window air conditioner as well as an 80-watt 42-inch LED TV, 100-watt computer, and most lighting in the home—especially if the lights are low-wattage LED bulbs. The best way to determine how much wattage it takes to run your home is to add up the wattage of all essential appliances and electronics.

While some generators are powerful enough to run home HVAC systems, keep in mind that most homes are not wired for this setup. One would need to have the home specially wired by an electrician to allow the generator to plug into a home’s entire power grid.

Dual Fuel

The vast majority of propane generators are dual-fuel generators. This means they can run off either a 20-gallon propane fuel tank or unleaded gasoline. Some can even switch fuels while running. One advantage of a propane generator is that propane fuel can be stored for long periods of time without degrading.

This allows the user to keep a supply of tanks on hand in case of a power outage, which is a lot easier than making a run for gasoline in the midst of a widespread power outage or dangerous ice storm.

Exhaust and Safety

Propane is a clean-burning fuel, which means it puts out far fewer pollutants than gasoline. This also means fewer fumes to worry about in the yard or at the campsite. This does not mean a propane generator is safe for use in an enclosed space.

Although propane generators produce little carbon monoxide compared to gasoline-powered generators, carbon monoxide is released when propane burns and can fill up an enclosed space. Carbon monoxide is odorless and colorless, dangerous and deadly. With that in mind, never use a propane generator in an enclosed space.

Portability

Because of the exhaust generators produce, they are safe only when used outdoors at least 20 feet from any structures. For this reason, most have large handles and wheels, or other features, to make them portable.

This does not mean that generators are lightweight: most propane generators weigh more than 100 pounds. Lightweight models with outputs of around 2,000 watts can weigh as little as 45 pounds, but heavy-duty generators that put out more than 10,000 watts can weigh over 300 pounds.

Noise

Generators are notoriously loud with decibel ratings that indicate how loud they are. Most generators run at about 70 decibels, which is similar to the sound of a car engine. Ultraquiet generators run at around 55 decibels.

Keep in mind that a generator running at full capacity will be louder than the same generator running at 50 percent of its maximum load. Every 10 increments on a decibel scale are equivalent to 10 times the sound. Therefore, a generator running at 70 decibels is 10 times louder than a generator running at 60 decibels.

Outlets

As is the case in our homes, outlets are the means through which appliances access the power created by a generator. All generators feature standard 120-volt outlets, with most having between two and four. Generators with outputs of 4,000 watts or more will also have 240-volt twist-lock outlets for large appliances, such as clothes dryers and electric ranges.

Some models also include 12-volt outlets, which are outlets similar to cigarette lighters in vehicles. RV-ready outlets feature special 30-amp or 50-amp outlets for powering a travel trailer or motorhome.

Our Top Picks

The list below narrows the field of propane generators to some of the best models on the market. Whether you prioritize portability, price, or some other feature, any of the generators below will help keep a fridge running, the lights on, and a heater or AC running when your home is without power.

FAQs

If you’re wondering about how much fuel a propane generator uses or how safe it is to use a propane generator, read on for answers to some of the most commonly asked questions about these machines.

Q: How much propane does a generator use per hour?

A propane generator uses about 2 to 3 gallons of propane an hour depending on the load. This equates to a total run time of about 8 to 10 hours on a full 20-gallon tank.

Q: How loud are propane generators?

A propane generator’s noise level is related to the amount of power it produces. Generators that produce 6,000 or more watts run at around 70 to 80 decibels, whereas a smaller generator that produces around 3,000 watts will run at 50 to 60 decibels.

Q: Is propane more dangerous to run than gasoline?

Propane generators are actually safer than gasoline generators. They produce fewer toxic fumes and do not pose as great a fire hazard as gasoline, which can spill. Propane is not susceptible to spills because it is contained in a pressurized canister.

Q: How can I safely use a propane generator?

To safely use a propane generator, make sure to set up the generator in an open space away from any enclosures, including an open garage.
