DuroMax XP4850EH review

This DuroMax XP4850EH generator has many great features that make it stand out from the rest of its kind. From the fully featured power panel that offers a selection of outlets for added compatibility to the low oil shut off that automatically shuts off the unit when the oil is too low, this model has got pretty much anything you could want in a residential generator. So, let’s check out the different features that this model has to offer.

Performance on gasoline

This DuroMax XP4850EH generator comes equipped with Dual Fuel Technology that allows it to run on either gasoline or propane, giving you a choice of what you would like to use each time you need it. With the use of gasoline, the generator’s peak watts come to 4,850 in total with the running watts at 3,850. With the running amps at 120 volts, the output is 32.08, with the peak at 40.42.

With the running amps at 240 volts, the output is 16.04, with the peak at 20.21. This powerful performance beats the propane performance ever so slightly, making this a good choice for running the generator if you are wanting more power at once.

Performance on propane

On propane, this DuroMax XP4840EH generator has the running watts of 3,658 with the peak watts at 4,608. At 120 volts, the running amps are 30.48, with the peak at 38.40. At 240 volts, the running amps are 15.24 with the peak amps at 19.20.

Although the performance is a bit lower with propane than it is with gasoline, many users prefer it because it burns cleaner than gas, which is better for the environment and for the generator as well.

Fuel tank capacity and run time

This DuroMax XP4840EH generator comes with Duel Fuel Technology that allows you to choose between running on either gasoline or propane. So, the fuel tank capacity when running on gasoline is 3.96 gallons. If you are using propane to run the generator instead, then the suggested propane tank size is 20 gallons.

When running the generator on gasoline, the run time at half of a load is 10.42 hours in total. If you choose to use propane instead, then the run time at half of a load will be 8.92 hours. Although both can run for quite a long time, it is important to note that whether you are using the gas or propane to run the generator, you can not run the generator indoors at any time.

It is always recommended to run a generator outdoors. It is safe to run it in the garage, but there must be good ventilation with the garage door – and side door if there is one – left open for airflow. If left indoors, or in the garage without proper ventilation, there is a high risk of carbon monoxide poisoning.

Control panel and outlets

This DuroMax XP4850EH generator comes with a fully featured power panel that has a selection of outlets that allow for maximum compatibility with different applications. The three outlets that it is equipped with are two 120-volt GFCI outlets that can connect with many different household electronics, and a 120 or 240-volt 30A twist-lock outlet that must be turned into place before connecting to give added protection from being pulled out from the plug.

This control panel also comes with a voltmeter so that you can check electrical currents of the generator and the battery, and a 12-volt DC charging posts that you can use to charge external batteries if needed.

Ease of use

DuroMax XP4850EH Review

This DuroMax XP4840EH generator is a great option for anyone who has trouble with gasoline-only engines. Gasoline engines can be difficult to pull-start, and it can be especially challenging for those who have physical limitations. You don’t want to be struggling in the dark, and with this generator, you won’t have to.

The electric start makes it easy to crank the generator and get it up and running in no time, which is necessary in times when the power is not running. Then you can plug in the electronics that you need to keep running until the power turns back on, and you can have long-lasting generator power for up to 8–10 hours depending on which fuel you choose to run on and your power demands.

Safety features

The DuroMax XP4840EH comes with a few safety features that keep you and your whole family safe while this generator is running. The first is the low oil shutoff feature which senses the oil getting low and will automatically turn off the unit. This is important because running your generator until it is out of oil can damage it significantly and could eventually render it unusable.

Having this feature will help to keep your generator working properly, and at optimal rates, for longer. This will also make your purchase more worth the price because it will ensure that your generator runs more smoothly.

The second safety feature is the surge assist protection. This feature helps to keep your generator safe in the event of a power surge so that you will not have to deal with it blowing up on you and not being able to be used again.

Noise level

This XP4850EH generator option has a noise level of 69 dB. This means that the noise level can be compared to the sound of a hairdryer running, or a washing machine being turned on. This noise level is fairly quiet and likely won’t be a nuisance.

Although, we will mention again that generators are not meant to run indoors, so you will be unlikely to hear much noise from it because of that fact. However, even if you choose to run the generator outdoors, you may keep doors or windows open that will raise the noise level. Playing moderately loud music would be likely to cover this standard noise level.


DuroMax XP4850EH ReviewThis XP4850EH generator model is highly portable because of its compact nature and lightweight structure. The dimensions of this product are 27 inches by 17 inches, which is fairly small in size compared to other options that are available on the market. This is especially true when taking into account industrial-sized models.

This unit weighs 127 pounds, which may seem like a lot, but the average weight of a residential generator can be between 250 and 300 pounds. So, in comparison, this option weighs much less than the leading competition and makes it easier to move around.

The DuroMax XP4840EH also comes with two wheels on the back end so that it can be easily pushed to wherever you want it, and makes it simple to change the position. There is a flip-up handle attached to the other side of the generator that you can pull up and use to push the unit like a wheel barrel.


Like all machines, there are a few things that you need to keep up with to make sure that your DuroMax XP4850EH generator will continue to run smoothly in the event of a blackout or power outage. So, the first thing that you should do is clean your unit periodically. This means that you should wipe down the unit and ensure that all dirt and dust is removed. You should also check for any leaks at this time so that you can fix them immediately.

You can choose to purchase a full cover for the generator if you want to cut down the amount of time cleaning and dusting, but you will still want to check for leaks periodically. You do not want to wait until you need the generator to check it, or else you may not be able to start it up and use it at all.

Secondly, you should change out the oil in the generator every 50 to 60 hours of use. This will improve the reliability of the oil and keep the generator running clean.


The DuroMax XP4840EH comes with a 3-year limited warranty for residential use and does not extend to commercial or unusually heavy-use. This warranty covers all parts in the event of a failure caused by manufacturer defects or a mechanical component malfunction. The warranty is non-transferrable and only covers the original owner of the unit, so it will not be covered if you bought it used.

If you need a replacement part, you will be responsible for covering the full cost of freight for the return of the defective part and the replacement part. The warranty also does not cover the effects of normal wear and tear on the generator due to regular use, and doesn’t extend to any accessories or aftermarket parts.


The price of this DuroMax XP4840EH generator is $550 a unit. This price is mid-range in comparison to some of the other leading competitors on the market. Other dual-fuel generators can range from the Champion Duel-Fuel unit that costs $450 apiece to the premium-priced Champion DH Series that costs $600 a unit.

With the DuroMax generator having a mid-range price, it is budget-friendly for many customers who would like a powerful option that won’t come with a premium price tag. Also, with the 3-year warranty, the price comes with replacements parts. Although, you will have to cover the costs of shipping even with replacements parts under warranty, so take this into consideration when making your purchase.
