With this review of the DuroMax XP4400E 4,400 Watt 7.0 HP OHV 4-Cycle gas powered portable generator with wheel kit and electric start, I hope I will help you make the best decision.

This is one of the most highly sought after generators in the market so it is important for it to be reviewed objectively. Below, I share my opinion on the features and capabilities of DuroMax XP4400E. Hopefully, you will find my evaluation and advice useful.

Product Description

The OHV engine of the gas powered generator makes 7 horsepower. It has air cooling. It is made from durable materials. The mechanical power produced is then transformed into electrical power. The device produces 4,000 watts of output when started and 3,500 watts of output with continuous operation. The capacity of the fuel tank is 4 gallons.

You will be able to start DuroMax XP4400E in two different ways. The electric start is super easy to work with. It is just like starting a car. The traditional recoil start is for backup. If the battery of the electric one is not fully loaded and it cannot work, then you can just pull the recoil to start the power generator. I certainly appreciate the ease of use of the electric start and the fact that it has a backup. You will be able to start the device easily and quickly whenever you need it.

There are four different outlets at your disposal when you use this portable diesel generator. There are two 120-volt 20-amp outlets. There is one 120/240-volt 30-amp twist lock as well. You can also use the 12-volt 10-amp utility to charge batteries. You can charge individual batteries and ones belonging to various devices. The outlets are standard so they are not a special feature to this model.

The patented RV Switch is one of the most notable features of the DuroMax XP4400E home power generator. This voltage selector allows you to regulate the power as per your needs. You can get maximum power from the two 120-volt outlets. You can also set the device to operate at 120 volts and 240 volts at the same time. If you set it to 120 volts only, you will be able to get full power.

The dual 15-amp circuit breaker is one of the most important safety features of this portable power generator. It is designed to prevent damage from overloads and, in my opinion it does a very good job. The volt meter is another feature which I find very useful. You get to monitor the output range and this makes the regulation of the voltage easier and more reliable. The automatic voltage regulation system is technically advanced and does an excellent job for ensuring the safe operation of the device.

DuroMax XP4400E has a low oil protection system just like most of its counterparts. Its purpose is to shut the device off when the oil is low to prevent damage. The exhaust, which is designed to work quietly, has a spark arrestor. This makes it safe to use in wooden structures and outdoors.

The muffler of this portable generator is designed to work very quietly. The four motor mounts with full insulation reduce the vibration and consequently the noise as well. This power generator produces 69 dB of noise. The device is not loud at all compared to most of its counterparts, but this does not mean that you will not be able to hear it at all.

The structure which supports this home power generator is worth looking at as well. I like the sturdy construction of the heavy duty steel frame. The tires are rugged and suitable for all terrains. Besides, they will not get flat. Using the handles is super easy and convenient.


DuroMax XP4400E produces 4,400 watts of surge output and 3,500 watts of continuous output. The continuous output is sufficient for powering a number of devices simultaneously such as a microwave, a coffee maker, a computer a TV set and even a fridge. You can also turn the heater or cooling fan on. You can power a cooking stove or a water boiler individually.

The run time at 50 per cent load when the tank is full is 8 hours. The run time is good, but there are models similar to this one that can do much better. I would recommend considering the importance of this factor to you individually.


This portable power generator can be used by households and business during power outages. It can be used for powering appliances in recreational vehicles and on camping sites. Contractors can also use it for their power tools.


The main benefits of the DuroMax XP4400E are:

  • Durability
  • Portability
  • Reliability
  • Versatility
  • Easy start
  • Safe and quiet operation


Here are the drawbacks of this portable generator for me:

  • Just 1-year limited warranty – most models from competing brands have at least 2 years of warranty.
  • Not easy to understand installation instructions especially for people with no technical experience – this is generally not a problem for me, but for many people it is a possible issue.


I believe that the DuroMax XP4400E 4,400 Watt 7.0 HP OHV 4-Cycle Gas Powered Portable Generator with Wheel Kit and Electric Start is a good-quality product worth using. It is designed to be durable and reliable. It works effectively.
