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 in need of an emergency backup power for their essentials
- Professionals in need of safely powering high-intensity work or lighting equipment
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.
Power & Run Time
The DuroStar DS4850EH
The DuroStar DS4850EH, equipped with dual-fuel technology and delivering 120/240V, ensures both power and versatility. Running on gasoline, it delivers a running wattage of 3,850W and a starting wattage of 4,850W. On propane, it provides 3,658 running watts and 4,608 starting watts.
The generator features a traditional recoil pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 69 dBA (less noisy than background music).
In terms of its run time capability, the DS4850EH, furnished with a 4 gallons fuel tank, can maintain operations for up to 23 hours on a full tank of gasoline (with fuel consumption averaging 0.17 gallons per hour). It also provides up to 18 hours (on a 20 lbs tank - propane consumption around 0.26 GPH) of operation with propane.
As the DS4850EH exhibits a THD of less than 12%, which is relatively high, it is best avoided for powering sensitive electronic devices.
Outlets
The control panel features the following 3 AC outlets:
Furthermore, it has 1 DC outlet: there's a 12V 8A output enabling simple battery charging for added ease.
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
Measuring L25 x W24 x H21 in, the classic open frame build of the DuroStar DS4850EH delivers stability and easy maintenance access to components, facilitating air circulation. This type of design is ideal for tough environments and heavy outdoor use.
While weighing 122 lbs, the generator is classified as 'portable,' indicating its mobility, albeit its heftiness may limit portability in specific situations. However, the lack of maneuverability can be offset with its wheel kit (⌀8") and its folding handle, which allows for convenient shifting once the generator is placed on the ground.
Features
The DS4850EH's control panel
Included in the control panel of the DS4850EH are a convenient voltmeter, which provides an easy way to monitor power output anytime, essential for monitoring its status and activity.
In addition to this info, the generator's light indicator provides visual feedback when its oil levels are insufficient.
Benefiting from its built-in fuel gauge, the generator allows for easy and immediate gas level inspections.
As far as security is concerned, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during use.
Apart from the standard documentation and an owner's manual (opens in a new tab) to facilitate setup, the DuroStar DS4850EH features extra accessories: tool kit, funnel, propane hose and battery charging cables.
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).
- With its weight of 122 lbs, the DuroStar DS4850EH is one of the heavier dual fuel generators in the 3500-4500 rated wattage category. 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.
- 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 is a concern for you, you could consider the Westinghouse iGen5000DF, which is one of the least noisy generators in its power range, rated at 52 dBA.
- With a run time of up to 23 hours at 25% load, the DS4850EH has one of the higher run times, compared to its similarly powerful peers. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Firman WH03662OF, as it provides up to 25 hours.
- Run time is a key metric, but it's dependent on the generator's fuel capacity. Therefore, discussing fuel efficiency is necessary to get the full picture. This generator, with an estimated fuel consumption of just 0.17 GPH (gallon per hour) at 25% load, is one of the more fuel-efficient generators, for the previously mentioned wattage range. If you're placing a high priority on fuel consumption, the Champion 201319, with a low fuel consumption rate of 0.16 GPH, could be an option to consider.
Price comparison
As you can see from these interactive charts, 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.
