Zoom on the DuroStar DS4850EH
In summary, the DuroStar DS4850EH is a portable generator especially useful for:
- RV travellers looking for even more independence
- Occasional participants of outdoor events, competitions, concerts and 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
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
Thanks to its dual-fuel technology, the DuroStar DS4850EH delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3,850W and a peak wattage of 4,850W. When propane-powered, it has 3,658 rated watts and 4,608 peak watts.
Enjoying a noise rating of 69 dBA (less noisy than a normal conversation), this generator can be started thanks to a conventional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included).
With a fuel capacity of 4 gallons, the DS4850EH can operate for up to 23 hours using gasoline (fuel consumption around 0.17 GPH), or for up to 18 hours (on a 20 lbs tank - propane consumption around 0.26 GPH) using propane.
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:
In addition, it provides 1 DC outlet: there's a 12V 8A output with which charging your batteries is made easy.
As it features a twist-lock L14-30R receptacle, the DS4850EH is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.
Portability
The dimensions of the DuroStar DS4850EH, which are L25 x W24 x H21 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
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, 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
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 serves to show you when the oil level is too low.
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.
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: battery charging cables, tool kit, propane hose and funnel.
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, making it usable in forested areas.
Product Video
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).
- A weight of 122 lbs makes the DuroStar DS4850EH one of the heavier dual fuel devices 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 DF402iX, 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 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.
- As the DS4850EH features an autonomy of up to 23 hours at 25% load, it has a higher run time than an average generator of its type and power range. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Firman WH03662OF, which is able to run for up to 25 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 is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.17 GPH (gallon per hour) at 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Champion 200988, with a fuel consumption of 0.16 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.
