Best Portable Propane Generators

Sure, you can use gasoline, diesel, or even solar power, but propane is one of the easiest, cheapest and safest modes of power.

Compared to a lot of other fuel sources, propane is considered as a clean burning fuel due to its relatively low emission output.

It also stays in good condition for a long time, unlike fuels like gasoline or diesel. This means if you only use your generator once in a while, propane is usually the best option to go for.

They’re also quiet, which makes them a great choice for camping, tailgating, or even as an emergency backup.

In this article I’m going to outline the best propane generators for you, as well as what to look out for, and the best ways to use them.

What makes the Duromax interesting is its build around its OHV (Overhead Valve) motor engine. Overhead valve engines tend to be far more efficient in their fuel use, thanks in part to the placement of their intake and exhaust valves.

The 7.5 horse power motor in this generator can crank out between 4,500 and 5,500 watts of power. This might seem a little more modest than some of the other generators on this list, but it lasts for much longer.

Further to its fuel efficiency, the Duromax is a generator that at its heart is smooth and quiet. This is done with its steel cage and isolated engine mounts, as well as its mounted muffler.

The generator includes two 20-amp and 120 volt outlets for household use, making it a great backup power source for your home appliances should your mainline fail you.

Got any burning questions? Our list of frequently answered questions are here to help.

How does a propane generator work?

Propane generators work much in the same way as many other types of power generators. They use propane as a fuel to then generate electricity, to then be used with appliances on the road, or as an emergency backup system (source).

Power is generated by using a motor to run off propane, before then converting that power into electric energy.

Because propane is a burnable source of energy, electricity can easily be generated by burning the propane which in turn creates heat and energy.

What are the advantages to propane generators?

Propane generators help you get the very most out of outdoor grilling on the road, particularly for your portable RV grill or tailgate grill.

Propane is a clean burning fuel (source) by virtue of the fact that it emits far less carbon monoxide than charcoal or wood. This makes it far less harmful for the environment than other fuel sources.

Check out our guide to the best propane tank gauge units.

Not only this, but it’s also far quieter when burning and safer to use.

Solar powered generators are increasingly popular, but these leave you at the mercy of sunlight and weather, meaning that they’re often only useful during the summer months.

Propane also doesn’t deteriorate in the same way that gas and diesel do. Propane essentially has an infinite shelf life, which means that you can buy in bulk for future use. This makes it extremely cost-effective and reliable.

What are the disadvantages to propane generators?

The main disadvantage is that propane can be a bit harder to find than other types of gas or petrol. However anyone with a propane gas BBQ grill will know where to get them.

Are propane generators more efficient?

In terms of pure power, propane generators aren’t as strong as gas or diesel powered options.

However, propane generators are much more fuel efficient in terms of return on amount used.

When compared to petrol or diesel, propane burns significantly less.
