DuroMax XP5500EH vs. Champion 4000-Watt Inverter Generator

The DuroMax brand is known for making some of the best dual fuel generators in the market.

That is what you will get when you opt for the XP5500EH model. Since it has the dual fuel technology, then you can get a lot more hours out of the generator when you use both fuel sources.

The Champion brand is still one of the best when it comes to making reliable, powerful, and affordable generators. That is what you get when you opt for the Champion 4000-watt generator. It has enough power to handle several electronics in your house or RV as a portable power source.

This guide is about comparing these two generators on overall. You will have the best information to make up your mind once you get to the end of the guide. First, let us see what you look for when buying a generator.

What to Look For


The generator runtime largely varies from one brand to another.

There are some models that can run for even twenty hours on a single tank of gas or whichever the fuel source.

Most of the claimed runtimes are often based on when the generator is running at 25% load capacity. So, make sure you keenly understand the runtime before picking the best model that works for you.

There are some models that now have a clever throttle action or economy mode. This ensures that you get the best runtime.

The economy mode in most cases is when the generator dials down the engine speed to produce enough power depending on the load connected to it. There is no doubt this will reduce the fuel use and the overall noise generated.


The outlets come in handy for you to connect to the generator with ease.

The number of outlets is important for someone who wants a portable generator. This is because the outlets will determine how easy it will be to connect to the generator.

There are some models that are transfer switch ready. You simply connect them to the house transfer switch with no additional cabling and now you can power the house.

There are other models that will be RV ready too. This is great news for those that might be looking to connect the generator to their RVs.

Other than the AC outlets, you will also get generators having the DC outlets too. They will help a lot in giving you the best power for charging the batteries with ease.

Depending on a unit, some can come with USB ports. Such ports would allow for ease of charging your mobile devices without an adapter.


When you decide to get a portable generator, you are hoping that it would be easy to move around with it.

Several factors determine portability and they include the size and weight.

For a portable generator, we expect it to be lightweight and compact in size. Even if it is not lightweight, it would have handles or wheels or both to help in moving the generator around.

Any generator about 100 lbs. is going to be hard to lift. However, it is still within what you would say is portable for a generator.


You should also consider the safety features that come with the generator. These are the features that can improve the overall usability of the generator.

There are some models that can automatically shut off in case there is an increase in the carbon monoxide build up beyond a certain level.

Others will shut down in case of an overload or when the oil level is low. These two are meant to protect the generator from damaging itself.

We recommend that you always keep in mind the proper use of the generator each time you get one. This will generally improve the overall durability of the generator for years to come.

Power Output

The power output is an important consideration for anyone who is looking for a generator with enough power to handle the electrical load.

Go for a powerful generator based on its rated power so that you can have enough power to run several electronics and appliances.

You still have to consider the stability of the power that you get from the generator. Look at the THD level to see if it would be good for sensitive electronics or not.

For sensitive electronics, the THD needs to be less than 3%. This means that you would end up with clean stable power all the time.

Ease of Use

Another consideration is how easy it will be to use the generator.

One way that would determine if the generator will be easy to use is the starting mechanism. You need to get yourself a generator that can quickly start even if it relies on using the recoil starting mechanism.

There are some models that would have electric starts that make it easier to start the engine at any time even if it means dealing with a cold start.

Having a well-laid out control panel will generally make the generator easy to handle and run. We recommend that you check out the various options in terms of generators to see which one would be easy to use.

Let’s Compare

DuroMax XP5500EH Fuel Portable Generator

DuroMax XP5500EH Fuel Portable Generator, Blue/Black

The DuroMax XP5500EH dual fuel generator is all about giving the best power that you need for handling various applications. Since it is dual power, you get the chance of running it on different fuel sources as you please.

The model is a great value for the money. Here are more of its features that would make someone get it right now.

The Run Time and Power

Considering that this generator comes with dual-fuel technology, it should be interesting to see how it works and how much power it can generate.

When running on gasoline, the generator has an output of 4500W running watts and 5500W peak watts. It is easy to see that it can be ideal for running multiple electronics at any given time.

When it is running on propane, the generator delivers 4273 rated watts and 5225 peak watts. As much as propane might yield less power, the difference is not by much. You will still like the kind of power you get out of the generator.

Another reason for getting the generator should be its run time.

The generator has an impressive run time of 9 hours on its 4-gallon fuel tank. This is when it is running on gas and 50% load.

When you switch to propane, the model can operate for around 8 hours. It is easy to see that you will always have an impressive run time regardless of the fuel source that you use.

Noise Level

It is an interesting generator as it is not quite noisy as you would expect from a generator of its size.

This generator has a noise level of 69dBA which is less noisy than what you get with background music. You can even run the generator the whole night without people complaining that it is making a lot of noise.

The model comes with an electric starter mechanism. Such a kind of starting mechanism will always make it easier to get the generator up and running.
