Description
Zoom on the DuroStar DS4850EH
In summary, the DuroStar DS4850EH is a portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals who want to be able to deliver results, even during a power failure
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 DuroStar DS4850EH
With its dual-fuel technology, the powerful and versatile DuroStar DS4850EH provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 3850W along with a peak wattage of 4850W. While propane-powered, it provides 3658 rated watts and 4608 starting 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).
As for its running time, the DS4850EH, along with its 4 gallons fuel capacity, can run for around 10 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.4 GPH). If propane is used, it can operate for around 9 hours (on a 20 lbs tank - propane consumption around 0.52 GPH).
As the DS4850EH has a relatively high THD (<12%), it is not recommended to use it to power sensitive electronic devices.
Outlets
The control panel provides the upcoming 3 AC outlets:
Additionally, it features 1 DC outlet: there's a 12V 8A output allowing you to easily charge your batteries.
As the DS4850EH 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
The DuroStar DS4850EH 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 device has been designed for tough environments and demanding outdoor use.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 122 pounds. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.
Features
The DS4850EH's control panel
To help you monitor the DS4850EH's status and activity, its control panel is equipped with a convenient voltmeter, which provides an easy way to monitor power output anytime.
In addition to this info, a light indicator allows you to instantly see if its oil levels are insufficient.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the DuroStar DS4850EH, the following accessories are also included: propane hose, tool kit, funnel and battery charging cables.
Emissions
The DuroStar DS4850EH 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, so it is adequate for use in forested areas.

The DuroStar DS4850EH versus other generators
The following charts are provided to give you an idea of how some of the key specs of the DuroStar DS4850EH compare to generators of similar power (between 3500 and 4500 W).
- At a weight of 122 pounds, the DuroStar DS4850EH places in the expected weight range of the generators in the 3500-4500 rated wattage range. 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.
- Among the generators of a comparable running wattage, this generator with a lowest noise of 69 dBA can be judged as noisy. If noise emissions are important to you, one of the least noisy generators of this power range is the Cummins Onan P4500i with only 52 dBA.
- Regarding its autonomy, the autonomy of the DS4850EH, reaching around 10 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Predator 4375, as it provides around 16 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. This generator has an estimated fuel consumption of roughly 0.4 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. 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 DuroStar DS4850EH is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
