Duromax Generator as you know that manufactures in Ontario, California. It was established in 2003 and is now regarded as one of the top manufacturers of portable gasoline generators. It offers top-notch generators that are appropriate for a variety of functions. Along with generators, their selection also includes engines, pumps, pressure washers, and various accessories. The Duromax generators are renowned for their sturdiness and relatively extended runtime.

All the products from Duromax are also known for being reasonably priced. They are on the more affordable end of the pricing range when compared to some other generators of various manufacturers and have the same quality.

In this article, I have reviewed the well know Duromax Generator XP4400E which is very reasonable, sturdy, and efficient in working. While experimenting with this generator I have observed its many qualities and very few downsides that I am going to discuss below. So keep up with me to get to know each and everything about this generator.

Key Features

If you experience frequent power outages, a Duromax XP4400E generator is a need. In an emergency, you can depend on it to run your household appliances for several hours straight because of its power and runtime.

Heavy duty engine

The Duromax OHV 4-stroke engine powers the Duromax XP4400E. It has a 7 hp motor, operates on gasoline, and switches between 120 and 240 volts. 3,500 watts are used during operation, while 4,400 watts are used during peak operation. This low-priced generator is an amazing engine.

Heavy duty engine


Knowing a generator’s noise level before purchasing it is highly crucial because generators are typically fairly loud. For some uses, nocturnal use, in particular, too loud generators may not be appropriate. While observing this generator the first thing that I noticed is its noise level.

You should be aware that as the decibel value rises by 10dB, the volume of the sound increases tenfold. Because of this, the 70dB generator is ten times louder than the 60dB generator. The majority of generators have a noise level between 75 and 80 dB, hence those with a noise level under 70 dB are regarded as being quiet. The Duromax XP4400E has a noise level of 69dB, which is not much louder than certain ambient music. I have put it outside my house and no one was disturbed because of its noise.

Electric Start

Together with the traditional pull-start technique, the starting mechanism also features an electric key start, which is significantly simpler to use. Checking the fuel and oil levels, grounding it, turning the fuel valve to the “on” position, and depressing the choke button is all that are required to start the generator.

Don’t forget to later deactivate the choke button. Also, you may always refer to the handbook or contact the technical support services if you experience any difficulties when using the generator.


Building quality is only one factor in durability. It is the generator’s capacity to tolerate difficult circumstances. It guarantees the portable generator will last longer.

The DuroMax XP4400E portable generator’s prolonged engine life is designed to withstand demanding conditions. Both the construction and the winding are made entirely of copper. Both lengthen the engine’s lifespan.

This generator has a surge arrest device built in. It guards against power spikes in the generator engine.


Moreover, this generator incorporates an automated shut-off sensor for low oil. The engine is turned off by this low oil protection when the oil level drops below the minimum acceptable level. It guards against any damage the engine might sustain as a result of low oil levels.

Maintenance of a generator is compulsory if you want to use it for a long time. Cleaning and maintaining it is not a big task but you must need little expertise. You can read our article on generator maintenance tips for details.

Fuel Capacity

The Duromax XP4400E has a 4-gallon gasoline capacity. It enables you to run the generator at 50% load for more than 8 hours. It’s not that much compared to other generators in this class, like Champion 100573. Because of its more powerful engine, the 100573 generators can run for up to 17 hours. While its other features are almost similar to Duromax XP4000E.


The Duromax xp4400e portable generator is 24 by 17 by 17 inches and weighs 100 pounds, so it is not a small generator. Although it is referred regarded as a portable generator, it cannot be used for camping or tailgating. However, using it at your workplace or at home for some domestic chores won’t be a problem due to its heavy and bulky form. Both a foldable handle and the wheel kit enable portability.

Control Panel

A convenient voltmeter is included in the control panel, so controlling power output won’t be an issue. The light indicator, which warns you if the oil level is insufficient, is another fantastic feature. As a result, there will be less difficulty starting the generator because you will be aware of the need to add oil. Moreover, there is an automated low oil shut-off for safety purposes.

The generator itself, the Duromax XP4400E manual, a tool kit, a tiny funnel, and battery charging connections are all included in the package. I have found this generator very convenient for household usage.

Safety features

When using a portable generator, proper precautions must be taken. I always recommend checking the safety features of the generator first. Because portable generators produce toxic fumes and particulates in addition to electric power.

A portable generator also produces carbon monoxide when it is running. Another name for this gas is “the silent killer.”

Guidelines for emissions are provided by the EPA and CARB. A generator that complies with EPA and CARB regulations keeps its pollution levels in check.

The DuroMax XP4400E was created with a low-emission engine in mind. The EPA and CARB have certified this generator. So you can use this without any worry.

A 3-year limited guarantee is offered on this generator.

  • It needs very little maintenance
  • It has a heavy-duty 4-stroke engine
  • It accompanies a variety of power outlets
  • It has a low running capacity as compared to other alternatives
  • Its manual should be more detailed

DuroMax XP4400E Review – FAQs

What is DuroMax idle control?
When a load is required, the automated idle management feature helps lower the RPM and save fuel while the generator isn’t drawing a load. If a load is demanded, the generator will return to its usual RPM and fuel consumption rate.
Are DuroMax generators pure sine wave?
Inverter generators produce a straight, clear AC sine wave. Less than 3% THD is measured by Duromax AC inverters.
Can you run a DuroMax generator in the rain?
DuroMax generators may easily be used in torrential downpours with the right shielding, but they should never come into direct contact with water.
Does a DuroMax generator charge its own battery?
Absolutely, while the generator is running, the onboard battery will be automatically recharged on all of our electric start generator models.
What are the disadvantages of DC generators?
The inability of a DC generator to be used with a transformer is a significant drawback. A DC generator has very poor efficiency. Eddy current losses, copper losses, mechanical losses, and other losses occur to the current flowing in the generator.



The fact that each portable generator operates a little bit differently means that there is no one-size-fits-all method for purchasing one. When looking for a unit that fulfills your requirements, it is imperative to keep this in mind. The Duromax XP4400E is a fantastic option if you’re searching for a portable generator with a strong engine, low emissions, and safety features.

We have also provided you with the alternatives, each having its own specific qualities. If you want a long runtime Westinghouse 4500-watt generator is for you. And if you want something reasonable and efficient at the same time Duromax XP4400E is the best option.
