Best Dual Fuel Portable Generator – Comparison Table
How Does a Dual Fuel Generator Work?
A dual fuel generator works the same as a single fuel generator, except that it can burn both gasoline and propane to produce electricity. The generator transforms the mechanical energy produced by burning fuels to force electrical charges to move and generate electrical energy.
Are Dual Fuel Generators Worth it?
As generator fuels, propane and gasoline have their advantages and disadvantages.
- While gasoline is a widely available fuel, propane gas is not that easy to find. However, propane is cheaper than gasoline, making it a great option if you’re looking to save fuel.
- A dual power generator works well in areas with large fluctuations in temperature between seasons. This is because propane is a better fuel source for humid temperatures. In contrast, gasoline is better than propane gas in chilly weather.
- Many of these dual fuel generators can power most of your appliances such as Laptops, CPAP machines, iPhones, iPads or entertainment systems on the go.
- A dual fuel generator can save you money by using cheaper propane instead of gasoline whenever it is available.
- With a dual fuel generator, you can switch between propane and gasoline based on ambient temperatures.
- Extend your generator’s overall life by using a full gas tank and then switching to a full propane tank before you need to refuel.
Single Fuel Generators vs. Dual Fuel Generators
|Single Fuel Generators||Dual Fuel Generators|
|Runs on only one type of fuel||Allows you to switch between two fuel types|
|Releases more carbon monoxide||Cleaner burning fuel|
|Limited runtime as it runs on only one type of fuel||Offers longer runtimes and more power|
|Requires frequent maintenance||Requires little to no maintenance|
Can you Run a Dual Fuel Generator on Natural Gas?
Although some single fuel generators may be suitable for natural gas use, dual fuel generators will not. Unless specially developed, dual fuel generators cannot run on natural gas and can’t be adapted for this purpose.
Do Dual Fuel Generators Have Remote Start?
Yes, some dual-fuel generators have remote start. As with an electric start, you don’t have to worry about starting the engine to get it to work. With remote start, you can start the generator from anywhere. Like a key fob for your car, you can start the generator with remote control from your motorhome or camp tent.
How Can I Increase the Run Time on my Dual Fuel Generator?
No problem; a dual fuel generator can help you in this situation.
- All you have to do is fill your generator’s gasoline tank and attach a propane gas cylinder with it.
- First, run your generator on gasoline. After powering off, turn the fuel selector knob to propane and start the generator.
- This way, you don’t have to fill your gas tank in the middle of the night, and you have minimal downtime.
Is it Necessary to Ground a Portable Dual Fuel Generator?
It is best if your dual fuel generator is grounded correctly, as this could result in electric shock. Your owner’s guide will discuss the steps involved in grounding it. If you can’t perform these steps yourself, an electrician can help you properly ground your dual fuel generator.
How Long Will a Dual Fuel Generator Run on Propane?
Most large above or below-ground propane tanks have a capacity of 500-1000 gallons.
- Standard propane tanks that you can find outside your local grocery store weigh 20 pounds and hold 4.5 gallons of propane and weigh about 37lbs when full.
- Expect a propane gas dual fuel generator to burn 2 to 3 gallons per hour. A 500-gallon tank will provide continuous power to your RV for a week.
- A 1000-gallon tank will last 2 weeks.
What to Look for?
Keep these critical factors in mind when purchasing the best dual fuel portable generator for your RV, campsite, or outdoor events.
A) Fuel Capacity
Dual fuel portable generators have an isolated gas tank with a fuel capacity of as little as 2 gallons to over 10 gallons.
- The larger the generator fuel tank, the longer it can deliver gasoline.
- The fuel capacity does not affect the amount of propane used with your dual fuel portable generator.
- This is because propane is stored under pressure in containers connected to the generator with a pressure regulator and a hose for direct fuel consumption.
B) Power Output
The power output of dual fuel portable generators is measured in watts (W). It is specified as running power output and peak power output.
- The peak power output is the maximum power the generator can deliver at any given time. In contrast, the running power output is the average power that is generated during operation.
- Depending on the generator’s functionality and size, dual power generators generate an output power of between 1, 000W and more than 12, 000W.
- Depending on the manufacturer, this can further be divided between the running and peak output of propane and the running and peak output of gasoline.
- These numbers are given because gasoline can produce more energy than propane. However, many dual fuel portable generators do not distinguish between the two fuels when reporting running and peak power.
- Instead, they indicate the highest numbers with gas so you can measure the propane range.
C) Electric Start vs. Recoil Cord
You can start a dual fuel portable generator by pulling a recoil cord or an electric start switch.
Electric Start: This type of start switch on a dual fuel portable generator is very convenient to use. The generator stores additional energy in an internal battery that automatically turns the generator on when you press the keypad or the FOB key. This starting method is much simpler than using a recoil wire, but it requires electricity stored in the generator. You cannot use an electric starter without a charged internal battery.
Recoil Cord: Although old, the recoil cord is a reliable technology that has characterized generators, chainsaws, lawnmowers, and other fuel-powered tools for many years. This method of igniting the generator needs you to pull the recoil cord quickly and steadily to start the engine. While starting the generator requires some effort, it is not necessary to rely on electricity. This way, you can start the generator at any time, even if you have stored it in the shed or garage for some years.
D) Operating Noise Level
Using a power tool or accessory makes noise.
- However, the goal is to find a dual fuel portable generator with the lowest noise level that still produces enough power for your needs.
- The operating noise level is typically measured in decibels (dB). A dual fuel portable generator generates a dB level between 50 dB and 90 dB, depending on the fuel used, the generator size, and the power output.
