Duromax is known for a wide range of products in the power generating set market, but not many know of their prowess in developing portable units. However, that does not stop the company from producing high-quality units which are as functional as they are portable.
One of such units is the impressive Duromax XP4400E generator.
So today we’ll review the DuroMax XP4400E, its features and specs, pros and cons, wattage demands, and how it stacks up against the competition.
Let’s dive in..
Overview of the Duromax XP4400E
It is challenging for us to choose a place to start from. Maybe we should set the ball rolling by talking about the body build.
If you are familiar with generating sets that come from the stables of Duromax, the choice of blue coloration with black details won’t come as a surprise to you. The company prides itself with those colors for years now, and they are not about to stop on the Duromax XP4400E generator. However, the colors are the only element there for aesthetics. They are painted onto metal bars which supports the generator frame, provides protection to the fuel tank and also provides a means for lifting the unit where need be.
Even though it looks beautiful, the metal frame packs a lot of strength and would take a lot of abuse before letting anything happen to the engine or any other delicate part of the unit.
Going under the hood, we found out that the unit is powered by a 4-cycle engine which has the ability to crank up as much as 7 HP on a 208-cc engine displacement. This all translates to meaning the unit can attain a wattage of 4400W at the start of operation, which is evident from the name.
For sure, this wattage is bound to drop during operation. However, it would never go below 3500 watts – which is more than enough to power most homes, job sites and workshops.
Looking away from the power section, the unit is relatively quiet. Power generating sets are known to be loud and this one could have done better, but we can assure you that 69dB won’t be giving you a problem anytime soon. You can read how to reduce generator noise here.
Ensure the unit is situated away from the living area as far as you can manage, and you will be okay with the muffled sound from that far out.
As is to be expected from Duromax, they did slap on some new tech during the production of this unit. One of such is the MX2 Technology feature which allows you choose just how much energy you would like to get from the receptacles on board.
Putting that in context, they allow you run the unit on either of the receptacles, opting to shuffle between 120V and 240V or going all the way with 120V at full power. This makes the unit compatible with RVs out of the box.
As if that is not enough, Duromax has also provided you with some of the insurance you need.
The first is evident in the promise of a warranty that is bound to last 3 years. To ensure you don’t need that warranty claim for flimsy issues, a low oil shutoff feature helps kill the engine when the oil is either running low or getting too hot for comfort.
What better way to help protect you from engine knocks?
Furthermore, there is a circuit breaker in place to keep the unit from getting overloaded. When that happens, it warns you and shuts off if the load is not reduced.
But, that is a common feature of power generating sets these days. What is not a common feature, however, is the surge arrest feature – protecting your unit and household appliances from power surges during operation.
All that, and the DuroMax XP4400E still weighs 120 pounds. We can see you grinning at the fact that Duromax understands the meaning of mortality, but that’s not all – they still include wheels and handles for easy transport.
Now that you have learnt quite a good deal about the Duromax XP4400E, here is the rundown of features that makes it what it is:
Build – The Duromax XP4400E is developed with an all-steel body. This helps to supply the rigidity and sturdiness that the unit needs.
Run time – This unit can run up to 8 hours on unleaded gasoline when it is maintained at half load throughout the time of operation
Noise – Duromax has built in a super quiet engine muffler into the machine to ensure it doesn’t give off as much noise as would have been evident. That way, they have been able to keep the noise levels to 64 dB or below, depending on the load the unit is made to carry.
Idle control – This helps to hold the unit’s RPM at a constant level, even when it is under heavy loads. That helps to reduce the fuel consumption of the unit and as well, noise
Safety – The unit comes with a low oil auto shutoff valve which prevents engine knocking. A circuit breaker has also been built into the engine for the prevention of overload.
Finally, there is a surge arrest installation place to ensure your household appliances and the power generating set itself doesn’t fail from power surges.
Portability – Duromax did a very good job of making this one truly portable, ensuring it weighs no more than 120 pounds.
Ease of transportation – There are solid-fill tires on both sides of the unit as well as handles to aid the easy movement from one place to the other.
Fully-equipped panel – The unit comes with a highly detailed power panel which ships with essential features such as a volt meter, circuit breaker, the shutoff switch and power outlets
Power Outlets – There are three (3) main power outlets on the Duromax XP4400E. There are two (2) fully protected outlets with output ratings of 120V and a third one which can switch between 120V/ 240V configurations at will
Wattage – At the start of operation, the Duromax XP4400E will attain up to 4400W. As the operation begins to steady, the wattage is bound to drop to about 3500W
Starting mechanism – Ease of start is one of the laudable features here, being as the unit cam be turned on with a key. It even ships with its own battery out of the box
Safety compliance – The engineers at Duromax have ensured that this unit passes the EPA and CARB approvals

Where the Duromax XP4400E Excels
It is easy to see that this unit will naturally be a great pick for those that spend a lot of their times outdoors and need a unit they can carry around with them. It is also great for job sites where easy movement of the power generating set from one place to the other is very important.
However, that does nothing to take away from the practical applications of the unit to the home too. With as much as 4400W in the pipeline, this unit will be able to support heavy appliances such as televisions and refrigerators without breaking a sweat.
Of course, all that would be nothing if the unit did not have the heart for all the energy it wants to pump around. That is why we find the 4-cycle OHV engine with a displacement of 208 cc just right.
The above engine will generate as much as 7 HP when asked, and it won’t even be loud about it – at 64 dB. This is just the kind of unit that you need around the home.
We also love the fact that Duromax went big on safety and environmental compliance with this one. The latter is evident in the EPA and CARB certificates this unit has earned. For the former, you just have to embrace all of the low oil shutoff sensor, circuit breaker and more.
Lest we forget, this unit is one with a very good value for money. You don’t have to take our word for it. Compare it to other models with the same specs on the market, and see if you can get the same thing in the same price bracket.
Where the Duromax XP4400E Fails
We would have expected Duromax to finish up this good deal with great customer service, but they still seem to be lacking in that department. We don’t know if that will be changing anytime soon, but that is one risk you could take if you can gamble on the durability of the engine.
Likewise, we would have loved to see a bigger tank. Having a 4-gallon capacity is great, but what about if the generator was to run for longer?
Perhaps, this is what they made up for when they ensured the operations had been optimized enough to allow the unit last longer.

If you won’t be running large scale industrial operations or several heavy equipment at the same time, this Duromax XP4400E is just right for you. It supplies more than enough power most homes might need and will go as high as 4400W to support job site operations.
For camping, you might have to locate this generator far away from you. Even though it has been built to be as quiet as can be, machines will always be machines. Should your generator have a problem there are easy ways to fix it before calling a handyman.
Conclusion: Should I Buy the Duromax XP4400E?
We believe the best overall generator in this power class is the Champion 4250 Watt Dual Fuel Inverter Generator. However, the DuroMax XP4400E is a respectable unit in its class in terms of run time and it’s only a fraction of the cost of the Champion 4250.
If it is for a home, chances are you don’t need more than the power this unit supplies, and you get to keep its portability as an added bonus. For those whose jobs require them to be on the move (welders, electricians, etc.), you might find this a useful addition to the back of your truck too.
I’ve always been a lover of Mechanics and the engineering that goes on behind it. Naturally had a knack for fixing things and i’ve had lots of adventures that generators are second nature to me.
