Best Propane/Gasoline Dual Fuel Generators

dual fuel generators mDual fuel power generators are types of generators that can out-of-box use both gasoline or propane, which can be very helpful in emergencies where gasoline can be hard to find.

Also, propane as fuel has many advantages over gasoline - it is more environment friendly, it stocks up more easily, it is more engine-friendly fuel, etc.

Intro to Propane/Gasoline Dual-Fuel Generators

Gasoline (petrol, gas) is a commonly available fossil fuel and it is commonly used for powering cars, trucks, boats, power generators, and similar vehicles and tools and appliances via internal combustion engines.

However, in the case of an emergency, the gas is the first fuel that will people try to stock up and the first one that will run out.

Thus, having a dual-fuel out-of-the-box power generator gives the user an option of using whatever fuel is available, gas or propane.

Gas (Gasoline, Petrol) vs Propane

When compared with gas, propane:

- easier to store: unlike gas that contains various additives and in recent years ethanol, and has a shelf life of few months, propane is stored in the form of Liquid Propane Gas (LPG) in steel bottles of various sizes and can be stored for a long time, since LPG contains just - propane.

- safer to use: when gas is spilled, it evaporates slowly, creating a huge fire hazard. Propane, on the other hand, evaporates quickly and although it is also sensitive to sparks and open flames, it is less dangerous than gas.

- greener fuel: both gas and propane have a certain Carbon Dioxide (CO2) footprint, but the propane release less CO2 than the gas. Propane also creates less very dangerous Carbon Monoxide (CO) than gas - nonetheless, power generators always must be run outside and never inside!

- less output power: as a fuel, propane decreases the output power of power generators since it is less dense than gas. However, it burns cleaner, creating a very low amount of residues that can harm the engine, prolonging the engine's life.

Which fuel to use, gas or propane?

Use whatever fuel you have and whatever fuel is more convenient for You - most dual-fuel generators can change the fuel source "on the fly" with the simple switch.

Also, propane can be stored in tanks much larger than standard 20 lbs propane tanks commonly used for camping, propane grills and pits, and similar, allowing the power generators to operate without interruptions for days - just be sure to check your generator periodically, especially the oil level, temperature, load and other parameters important for proper generator operation.

The most important features and characteristics of dual-fuel generators include Running/Starting Watts, operating time on a single fuel tank at specified load, noise levels, receptacles, size and weight, warranty terms, etc.

Note: Power generators are complex units and when they arrive, be sure to read the manual/Owner's Guide thoroughly and to keep it close to the unit - it may be needed one day again.

When looking for a new propane/gas dual-fuel power generator, choose according to your own needs and preferences.


Propane/Gas Generators Up To 5000 Starting Watts

Propane/gas dual-fuel power generators with the Starting Watts of up to 5000 watts are relatively small and compact units that are commonly used in emergencies, for camping, tailgating, and similar.

Power generators in this class are mostly inverter generators - output electricity (voltage, frequency) does not depend on the engine's RPM, since it is controlled entirely by an electronic controller/inverter.

Portable inverter generators feature very low THD (Total Harmonic Distortion) often less than 3% THD and can be used for powering very sensitive electronic devices.

Due to their size and often "open frame" construction, these power generators are not the quietest power generators on the market. Nonetheless, they are quiet enough to be used even when camping or in the urban environment - just don't put them below the neighbor's window.

Here is our list of the best propane generators with up to 5000 Starting Watts:

Note: Amazon affiliate links (the 'Model' column) open in the new windows, feel free to check them for the most up-to-date offers and prices. Also, we have really tried to verify every single bit of information in this chart and article (and in the end - our website), but there are sometimes discrepancies found even in data from the official websites.

Again, power generators MUST be operated outside, but not near the windows, doors, ventilation inlets, or similar - these units emit fumes that contain colorless and odorless Carbon Monoxide which is a VERY toxic gas that is very dangerous to humans and animals.

Even if it rains or even snows, the unit nonetheless must be operated outside - opened garage door is not considered 'outside'. And if You have the need to run your power generator even in bad weather, consider purchasing a generator's cover that allows the unit to operate even under such weather conditions.

Whatever You do - stay safe ...
