Zoom on the DuroMax XP4850HX

In a nutshell, the DuroMax XP4850HX is a portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals in need of safely powering high-intensity work or lighting equipment

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The DuroMax XP4850HX in use

The DuroMax XP4850HX

With its dual-fuel technology, the powerful and versatile DuroMax XP4850HX provides an output of 120V. While gasoline-powered, it gives a running wattage of 3850W along with a peak wattage of 4850W. While propane-powered, it provides 3650 rated watts and 4600 starting watts.

The generator features a conventional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 69 dBA (less noisy than an office).

As for its running time, the XP4850HX, along with its 4 gallons fuel capacity, can run for around 10.4 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.38 GPH). If propane is used, it can operate for around 8.9 hours (on a 20 lbs tank - propane consumption around 0.53 GPH).

Outlets

The control panel features the following 3 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

In addition, it provides 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.

Because the XP4850HX is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The DuroMax XP4850HX has a conventional, open frame design, of the following dimensions: L23 x W25 x H22 in, which offers support and allows it to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 126 lbs. Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the DuroMax XP4850HX

The XP4850HX's control panel

The control panel of the XP4850HX includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

In addition to this info, a light indicator shows you if its oil levels are insufficient.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

The XP4850HX also benefits from Duromax’ CO Alert carbon monoxide shutdown. If CO levels become unsafe or rapidly increase, the generator will automatically shut down, an indicator will light red, and the engine will not restart for 5 minutes. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroMax XP4850HX also comes with some accessories: propane hose, funnel and tool kit are included.

Emissions

The DuroMax XP4850HX is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, making it usable in forested areas.

Product Video

The DuroMax XP4850HX versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP4850HX compare to generators of similar power (between 3500 and 4500 W).

  • With a dry weight of 126 pounds, the DuroMax XP4850HX finds itself in the expected weight range for generators able to produce between 3500 and 4500 rated watts. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 69 dBA is on the noisier side. If you are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • Autonomy-wise, with around 10.4 hours on a full tank at a 50% load, the XP4850HX is on the low end when compared to other generators of a similar power output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000X, boasting with around 16 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator has an estimated fuel consumption of roughly 0.38 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the DuroMax XP4850HX is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
