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.

The generator is rated for a noise of 69 dBA (less noisy than background music). Its starting mechanisms include a conventional pull-start mechanism and a convenient and easy-to-use electric starter (battery included).

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

Since the XP4850HX has a somewhat high THD (<12%), it is advisable to not use it for the powering of sensitive electronic devices.

Outlets

The control panel features the following 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 allowing you to conveniently charge electronics such as mobile phones and tablets.

As the XP4850HX holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.

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 featured design is ideal for the outdoors and all tough environments.

Since the generator weighs 126 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is 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 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, when the oil level is too low, you will be informed by the featured light indicator.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

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

The XP4850HX also benefits from DuroMax’s 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: funnel, propane hose and tool kit are included.

Emissions

The DuroMax XP4850HX 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, 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 dual fuel generators of similar power (between 3500 and 4500 W).

  • As its dry weight is 126 pounds, the DuroMax XP4850HX is one of the heavier of the dual fuel products which can generate 3500 to 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.
  • As this generator has its lowest possible noise of 69 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen4500DF with only 52 dBA.
  • As the XP4850HX offers around 10.4 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the dual fuel generators of a similar power. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse iGen4500DF, which is able to run for around 15 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This generator reaches an estimated fuel consumption of 0.38 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4500DF. With a fuel consumption of as little as 0.23 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 dual fuel 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.
