Zoom on the DuroStar DS4850EH
In a nutshell, the DuroStar DS4850EH 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 be able to deliver results, even during a power failure
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
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.
At a noise rating of 69 dBA (less noisy than background music), this generator can be started via a simple traditional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included).
Regarding its running time, the DS4850EH, with a 4 gallons fuel capacity can operate for around 10 hours at 50% load with a full tank of gasoline (fuel consumption around 0.4 GPH). When using propane, it can run 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 includes the following 3 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 8A output with which charging your batteries is made easy.
Because the DS4850EH 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 DuroStar DS4850EH has the following dimensions: L25 x W24 x H21 in. In combination with its conventional, open frame design, they provide support and allow 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 122 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nevertheless, thanks to its wheel kit and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.
Features
The DS4850EH's control panel
The control panel of the DS4850EH includes a handy voltmeter that allows you to easily monitor power output anytime, helpful for the monitoring of its status and activity.
In addition to this info, a light indicator shows you if the oil level is too low.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.
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: tool kit, funnel, battery charging cables and propane hose.
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 dual fuel generators of similar power (between 3500 and 4500 W).
- As its dry weight is 122 pounds, the DuroStar DS4850EH is one of the heavier of the dual fuel products which can generate 3500 to 4500 running watts. In terms of weight, one of the champions in their power range is the WEN DF402iX, standing at just 66.1 lbs.
- This generator, with its lowest possible noise rated at 69 dBA falls into the more noisy category, compared to other devices of a similar running wattage. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500DF, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
- The DS4850EH's autonomy is somewhat low end compared to devices of its type and power range, as it reaches only around 10 hours at 50% load on a full tank. 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.
- 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.4 GPH at a 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4500DF, with a fuel consumption of 0.23 GPH could be in your good books.
Price comparison
As you can see from this interactive chart, when compared to other 3500-4500W dual fuel 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.
