Aside from that, it is meant to provide electricity for a longer period of time with its bigger gas tank and easy switching capability to propane. It is also CARB compliant to boot!  The only thing it needs to address is the noise it generates.

When we came across WEN DF110T, the first thing we realized is that it is fuel efficient. Comparing it with dual fuel generators with the similar output of 8,300 running watts and 11,000 surge watts on gasoline and 7,500 running watts and 9,500 surge watts on propane, the WEN DF110T will not be left behind. It can hold 6.6 gallons of gasoline and run for 8.5 hours on half-load run time. It is equipped with a 457cc 4 –stroke, OHV engine and has an electric start knob.

Bottom line:

The WEN DF110T is one of the most purchased dual fuel generators in the market today. The reviews about it are impressive. It is equipped with a powerful engine that it also fuel efficient on both gasoline and propane. One area for improvement is the noise level. Although it is noticeable that generators with this much power have higher noise levels.

Westinghouse is a powerhouse brand when it comes to household appliances like refrigerators and air conditioners. Incidentally, these are the most important appliances that will need supplemental electricity which will come from portable generators when power outages happen.

The WGen7500DF is the perfect emergency backup because it runs on both gas and propane. You no longer have to worry about running out of fuel in the middle of the night or during natural calamities because you can easily connect this generator to your LPG tank. When you buy this product, it comes in ready with a hose and propane gauge.

If you have gasoline, it has a 6.6-gallon tank that can keep the generator running for 16 hours at full tank, which is a great deal for portable generators where other generators can only offer 6 to 10 hours. Instantly switch between the two fuel sources while the generator runs without harming your appliances. You can turn your generator on by using the Push Start Electric Button or the Remote Start Key Fob. The remote activates the unit even at a distance of 109 yards.

​PROS

  • ​Longer running hours at 16 hours
  • ​Push to start switch and remote key start
  • ​CARB compliant
  • ​Portable
  • ​3-year warranty

​CONS

  • ​Reports of oil leaks
  • ​Operates louder than other generators

Bottom line:

With a 16 hour running time, your area might probably have enough time to restore normal electricity supply in terms of emergencies. But it gives buying confidence if a generator can actually run that long in a single tank of gasoline.

You can never go wrong with a generator that can offer more emergency backup power like the Champion 7500W Portable Generator. It can power up your appliances for up to 8 hours with 6 gallons of gasoline, and 5.5 hours with LPG. You can also seamlessly switch between these two power sources without switching-off the generator.

 

This generator is equipped with a 4-stroke 439cc single-cylinder engine. When running on gasoline, it produces 7500 running watts and 9375 starting watts. On the other hand, it can generate 6750 running watts and 8400 starting watts on propane.

​PROS

  • ​Built-in surge protection
  • ​Push to start switch and manual recoil start
  • ​Portable
  • ​3-year warranty

​CONS

  • ​Shorter running time than other generators
  • ​Operates louder than other generators

Bottom line:

This is yet another powerful generator from Champion. It’s good that despite the availability of an electronic start option, this is still backed up by manual recoil start. The feature to switch between either fuel options even while the engine is running is an impressive showcase of the VoltGuard surge protector on the engine. Two areas for improvement for this generator would be the stability of the frame to minimize too much noise as well.

Small Dual Fuel Generators

It may be smaller in terms of its size, but it can compete with larger generators in terms of power. A 244cc Champion engine runs this generator with 3800 running watts and 4750 surge watts. It has a total run time of 9 hours on a full 3.4-gallon tank of gas and up to 10.5 hours on a full tank of 20lb. LPG.

Once common observation of users is the oil leak problems which we hope the brand can remedy in the soonest possible time.

There is a new technology added to the generators in the market today and it’s called the “parallel linking capability.” It connects two generators, so you get twice the power output at 50% less than the usual fuel consumption of a similarly rated generator. DuroMax XP2000EH generates a maximum of 2000 starting watts and 1600 running watts. Imagine having twice as much as that? You can run an air conditioner or a refrigerator, an electric stove and have some outlets to charge your phones.

This generator only weighs 47lbs. and it’s easy to take with you even on your trips. Although small, it runs for 6.5 hours at 50% load. Aside from that, this generator has a couple of smart tech in it. It has an Eco-Mode that helps lower the idle speed of the generator. This feature also reduces its noise and minimizes fuel consumption. It also has a lot Total Harmonic Distortion that aims to deliver stable and clean power especially for the most sensitive appliances and gadgets like laptops, tablets and mobile phones.

The control panel of the DuroMax XP2000EH has a low fuel, overload and maximum output indicator; a Gas and LPG switch, engine switch, Eco-mode switch, parallel operation outlets and two (2) 120V AC 13.3A outlets. DuroMax offers a 3-year limited warranty with a lifetime technical support for all their generators.

​PROS

  • ​Parallel linking ready
  • ​Portable and easy to carry
  • ​Eco-mode
  • ​3-year warranty

​CONS

  • ​Operates louder than similarly rated generators

Bottom line:

DuroMax XP2000EH Dual Fuel Generator is a portable generator with the charm of a powerful one. Its parallel linking capability sounds like a promise that you can always add another generator in case one is not enough. Likewise, if you have two units, you can take one with you and you will never have to leave your home without an emergency back up left behind. We’re hoping that the brand can find a workaround on the loudness of this generator.

Conclusion:

The modern world’s dependency on electricity is undeniable. It is evident how much research and innovation these generator companies are putting into their products. Buying a gas or propane powered generator need not be confusing to buyers anymore with the availability of dual fuel generators. And we hope we were able to make the selecting process easier for you with this dual fuel generator buying guide.
