Description

The XP4850EH Dual Fuel portable generator is designed as a powerful user-friendly unit that provides 4,850 watts of power using gas or liquid propane. Perfect for running household appliances and providing power to the jobsite. This Dual Fuel workhorse packs a punch and will keep you powered at home, at work, and at play.

Zoom on the DuroMax XP4850EH

In a nutshell, the DuroMax XP4850EH is a portable generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals who want to ensure that a power failure will not prevent them from working

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 XP4850EH in use

The DuroMax XP4850EH

The dual-fuel technology of the DuroMax XP4850EH allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3,850W and a starting wattage of 4,850W. If propane-powered, it gives 3,658 rated watts and 4,608 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 a normal conversation).

As for its running time, the XP4850EH, along with its 4 gallons fuel capacity, can run for up to 23 hours with a full tank filled with gasoline (fuel consumption around 0.17 GPH). If propane is used, it can operate for up to 18 hours (on a 20 lbs tank - propane consumption around 0.26 GPH).

As the XP4850EH has a relatively high THD (<12%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel includes the following 3 AC outlets:

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

In addition, it provides 1 DC outlet: there's a 12V 8A output with which charging your batteries is made easy.

Since the XP4850EH bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The DuroMax XP4850EH has a conventional, open frame design, of the following dimensions: L25 x W24 x H21 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

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 122 lbs. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀8") and its folding handle, once it is placed on the ground.

Features

Panel of the DuroMax XP4850EH

The XP4850EH's control panel

The XP4850EH's status and activity may be monitored conveniently via the control panel, as it features a handy voltmeter that allows you to easily monitor power output anytime.

In addition to this info, a light indicator serves to show you when its oil levels are insufficient.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the DuroMax XP4850EH also comes with several accessories, including: funnel, tool kit, battery charging cables and propane hose.

Emissions

The DuroMax XP4850EH is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.

The DuroMax XP4850EH versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP4850EH compare to dual fuel generators of similar power (between 3500 and 4500 W).

  • Considering its dry weight of 122 pounds, the DuroMax XP4850EH is one of the heavier dual fuel generators producing between 3500 and 4500 running watts. Regarding dry weight, one of the champions in the same power range is the WEN DF402iX, with a dry weight of only 66.1 lbs.
  • Among the generators of a comparable running wattage, this generator with a lowest noise of 69 dBA can be judged as noisy. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Westinghouse iGen4500DF, whose lowest noise levels reach just 52 dBA.
  • Since the XP4850EH boasts with a run time of up to 23 hours at 25% load, it can be safely judged as a device of a higher run time than most dual fuel generators of a comparable output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Firman WH03662OF, as it provides up to 25 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. At an estimated fuel consumption of 0.17 GPH (gallon per hour) at 25% load, this generator is a rather fuel efficient one within its wattage category. If fuel consumption is your top priority, we suggest to check out the Champion 200988, which has a fuel consumption of only 0.16 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from these interactive charts, when compared to other 3500-4500W dual fuel generators, the DuroMax XP4850EH is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.

    I bought this generator in 2020. I have used it multiple times…always works great.
    I think everything is about maintenance
    I have 6 propane’s tanks (20LB) for power outages
    I put gasoline -NO ETHANOL..3 times per year, to keeps the rubber tubes free of leaks..
    I bought a magnetic oil dipstick, to clean debris when you change the oil.
    I change the oil after 20hours of use.ALWAYS
    I keep the battery charged with a trickle charger.
    I Keep in shed location in the back yard with beach umbrella.
    Great generator for a great owner.

    Lo compre en el 2020. Muchas veces usado, siempre trabaja bien.
    Pienso que todo es un buen mantenimiento.
    Tengo 6 tanques de 20 libras para apagones.
    Le pongo gasolina SIN Etanol, 3 veces anualmente, para evitar fugaz en las tuberias.
    Compre un tapon de aceite magnetico, para limpiar de residuos al momento de cambiar el aceite.
    Cambio el aceite cada 20 horas.
    Lo mantengo en un encienrro, en el patio junto a una sombrilla de playa.
    Buen Generador para un buen propietario.

    It is junk. Arrived with bent frame but workable. It has no power, gets very hot, had to adjust valves as they were too tight and leaked, still can barely deliver 3000 watts on propane. It is worthless and never buy one. For warranty they send you a very damaged one that is no good either. They totally lie about what power they can make. In fact your ad here and theirs is higher for propane than the user manual you get with the unit. And fact is it can’t generate the lower number even. Warranty means nothing as they refuse to honor it and want it taken long distances for service, and send you more junk if they actually try to be fair. But who wants more and more junk. They lie about every specification. I will never buy from them again. Ever.

    + PROS:
    • NONE Except cheap price
    - CONS:
    • Can't generate power advertised. Predetinates on gasoline. Noisy and doesn't last long. JUNK. TOTAL JUNK
