On top of all these, the engine uses ball bearings, which last two times longer than needle bearings. 

In short, this generator is designed to last for years.  

What I Like

The XP10000HX has a lot of good qualities, but what stands out the most about it is its durable engine. 

It is the heart and soul of this generator, which is understandable since Duromax is primarily an engine manufacturer. 

What I Don’t Like

If there is something that DuroMax can improve about this product, it is the weight. 

The XP10000HX is a bit heavy, but it does have durable transport wheels. 

Also, it does not come with a remote start.

5. WEN DF400iX Dual Fuel Inverter Generator

41oFZLEHcXL. SL500

WEN makes another appearance with the DF400iX, the smaller cousin of the DF1100T. 

This model comes at a similar price point despite having a lower wattage.

That said, it does offer other key advantages that even out the value-to-cost ratio. 

This model is a great option for people who want a more compact generator.  

Product Highlights

The DF400iX is smaller than the DF1100T, with 4,000 surge watts and 3,200 rated watts on gasoline. 

Using propane gives you 3,200 surge watts and 2,900 rated watts.

So why should you pay around the same amount of money for it?

Let us take a closer look:

  • Quiet Operation

The first thing you notice about the DF400iX is that it is extremely quiet when running. 

To give you a better perspective, it can emit 58 decibels at a quarter of a load and 22 feet away. 

It is lower than the sound of an air conditioner or even a normal conversation, which clocks at 60 decibels. 

So if you live close to neighbors and do not want to disturb them, you should consider this product. 

  • Auto Fuel Selection

While the DF400iX is small, it offers a lot of advanced features.

One is the Auto Fuel Selection Technology, which maximizes the run time as you switch from one fuel source to another. 

It prioritizes the use of propane, automatically selecting it if there is enough LPG in its tank.

The generator will also use propane if you connect it to a propane tank. 

If it cannot detect any source of LPG, it will use gasoline instead.   

  • Compliant With Strict Emission Standards

Like the DF1100T, the DF400iX complies with the strictest industry standards. 

Its 212cc engine meets all the CARB and the EPA III requirements. 

So if you want to keep your carbon footprint to a minimum, you should try this generator from WEN. 

  • Carbon Monoxide Detection

The DF400iX comes with a CO sensor that can detect the levels of carbon monoxide in its surroundings. 

If there is too much CO in the area, the machine automatically shuts down before anything bad happens. 

This feature will help protect you and your family from poisoning. 

What I Like

The best thing about the DF400iX is that it runs smoothly and quietly. 

It is a great option for people who live in a crowded neighborhood. 

What I Don’t Like

While the DF400iX has many advanced features, it does not offer remote start technology. 


  • Extremely quiet operation
  • Safer for the environment
  • Has protection against CO
  • Maximizes use of propane


  • No remote start
  • Run time a bit low

Buyer’s Guide

If you are shopping around for a dual-fuel generator, you are making the right choice. 

However, there are a few things that you need to consider first before buying one. 

Fuel Capacity 

The first thing you need to know about dual fuel generators is that they come with a fuel tank. 

However, this tank is mostly for gasoline only. 

Propane comes in pressure canisters which you can attach to the generator and then consume directly. 

That said, if you want a generator that can provide gasoline-based power for longer, look for models with larger tanks. 


Next, you need to look at the power output of the generator, which is measured in watts. 

It determines how much electricity it can supply. 

Starting Mechanism 

There are generally two ways that you can start a generator. 

One is with a recoil cord, which is probably what you are more familiar with. 

It requires you to pull a cord quickly but steadily to bring the engine to life. 

This method requires a bit of a learning curve.

That said, once you get the hang of it, you should have no problems starting your generator.  

The second way of starting a generator is with the electric method. 

It involves a pushbutton or a key that you can flip or turn, which is much easier.

However, for this to work, the internal battery of your generator must have enough charge. 

Noise Level 

If you are like most people, you would want a generator that does not make much noise. 

Generally, dual fuel generators are louder when on gasoline than when on propane. 

Also, inverters are generally quieter than other types of generators. 


For some people, the generator’s weight is not an issue. 

However, if you plan to take it camping or tailgating, too much weight might be a deal-breaker. 

Dual Fuel Generator FAQs

1. Which is cheaper, running a generator on propane or on gas?

Propane produces fewer BTUs than gasoline, even when using the same amount of fuel.

However, propane burns more cleanly, which is better not only for the environment but for your generator as well.  

2. Do dual fuel generators run more quietly on propane?

Yes, generators using propane for fuel generally make less noise than those that run on gasoline. 

3. Are dual fuel generators worth it?

Yes, investing in a dual fuel generator ensures you have round-the-clock access to emergency power no matter how bad the gasoline supply gets. 

4. Is it OK to leave my generator running all night?

In terms of safety, the biggest concern with running your generator all night is carbon monoxide poisoning. 

That said, you can place the generator at least 20 feet away from your home or RV to minimize the risk. 

Also, CO detectors would help out a lot. 

5. What are the advantages of using an inverter generator?

Inverter generators throttle the engine up or down, depending on the demand. 

As a result, it won’t have to run full blast all the time, saving you more fuel. 

Which Dual Fuel Generator Should You Choose?

You can’t go wrong with any of these generators.

That said, we think that the WEN DF1100T is the best dual fuel generator for this year. 

It has a high power output, is easy to use, and has a lower carbon footprint than some of its counterparts. 

In short, it has all the features that you typically see in high-end, high-quality brands.
