Power & Run Time

The DuroMax XP4850HX in use

The DuroMax XP4850HX

Thanks to its dual-fuel technology, the DuroMax XP4850HX delivers 120V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3850W and a peak wattage of 4850W. When propane-powered, it has 3650 rated watts and 4600 peak watts.

Enjoying a noise rating of 69 dBA (less noisy than an office), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant electric starter (battery included).

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

Outlets

The control panel provides the upcoming 3 AC outlets:

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

Furthermore, it has 2 DC outlets: there's two 5V USB ports with which you may charge electronics, for example mobile phones or tablets, conveniently.

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

With its dimensions of L23 x W25 x H22 in, the conventional, open frame design of the DuroMax XP4850HX offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

As the generator's weight is 126 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, this lack of maneuverability is compensated by its wheel kit and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the DuroMax XP4850HX

The XP4850HX's control panel

The XP4850HX's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

In addition to this info, the device’s light indicator will display if the oil level is too low.

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 standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

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).

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the DuroMax XP4850HX also is packed along with the following accessories: propane hose, tool kit and funnel.

Emissions

The DuroMax XP4850HX is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used 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).

  • As its weight is 126 pounds, the DuroMax XP4850HX falls in the expected weight range of the devices in the 3500-4500 rated wattage category. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 69 dBA can be considered somewhat noisy. If noise emissions are one of your priorities, you may be interested in the Cummins Onan P4500i, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • The XP4850HX’s autonomy is somewhat low end compared to devices of its power range, as it reaches only around 10.4 hours at 50% load on a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000X, reaching 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. As this generator uses an estimated 0.38 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.

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.
