The DuroStar DS4850EH’s dual-fuel technology lets it put out 120/240V and gives it a lot of power and flexibility. If it is powered by gasoline, the device has a running power of 3,850W and a starting power of 4,850W. If it runs on propane, it has a rated power of 3658 watts and a starting power of 4608 watts. The generator has both a simple and elegant pull-start mechanism and an electric starter (battery included). It has a noise level of 69 dBA (quieter than a regular conversation). With a fuel capacity of 4 gallons, the DS4850EH can run for about 10 hours at 0.5 load with a full tank of gasoline (fuel consumption is approximately 0.4 GPH). If propane is used, it can run for about 9 hours (on a 20 lbs tank – propane consumption around 0.52 GPH). Due to its relatively high THD (12%), the DS4850EH should not be used to power sensitive electronic devices.
The control panel has 3 AC outlets: a duplex 120V 20A (5-20R) GFCI outlet and a 120/240V 30A (L14-30R) outlet.It also has 1 DC outlet with a 12V 8A output that makes it easy to charge your batteries.The DS4850EH is ready for a transfer switch because it has a twist-lock L14-30R receptacle.You can connect it to a breaker box to power your home when the power goes out.
The DS4850EH and its control panel have an easy-to-use voltmeter that lets you check the power output at any time.This makes it easier to keep track of its status and activity.In addition to this information, if the oil level is too low, a light on the device will show.A built-in fuel gauge makes it easy and quick to check how much gas is in the generator.In terms of safety, the generator can be used without worry because it has an automatic shut-off for low oil and an overload protection (circuit breaker).The DuroStar DS4850EH comes with the usual paperwork and an owner’s manual , which lets you start it right away.It also comes with a funnel, propane hose, tool kit, and battery charging cables.
The DuroStar DS4850EH is 25 inches long, 24 inches wide, and 21 inches high.It has a typical open frame design that makes it stable and allows it to be raised above ground level.The design works well in rough places and for hard outdoor use.Even though this device is technically portable (meaning it can be moved), it can be hard to move and use without special tools because it weighs 122 pounds.But its wheels and folding handle make it easier to move once it’s on the floor.
The following charts show how some of the most important features of the DuroStar-DS4850EH compare to other generators with the same power output.

- We compared more than 500 portable generators at 50% load. We found that there is “skewed right” distribution for the difference between 50% load and 25% load and the median comes at 1.43. With this number we converter all the 25% load runtime to 50% load. Same with the propane efficiency, where median is 1.38.
- For some generators where propane runtime was not given, we used NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs. of propane = 1 gal of gasoline. All propane runtime is for 20 lbs. propane tank (4.7 gallons).
- Unlike many other sites, we actually tried to find out information about each of the above requirements. However, we are human and are therefore capable of the odd oversight or mistake. Please let us know if you spot any missing or erroneous values so that we can fix them.
About the Manufacturer
The Ontario, California-based business DuroMax, which was established in 2003, is the owner of the DuroStar name.Typically, DuroStar generators and DuroMax generators are identical, with the exception of their color schemes and the manufacturing facility.Although DuroStar engines and generators are made in China, the US is home to the design and servicing centers.
The warranty for the DuroStar DS4850EH lasts for up to 3 years.This warranty may not cover all parts of the generator or may only cover certain parts.Check out DuroStar’s (DuroMax’s) warranty policies to learn more about the warranty on DuroStar generators.You can also call their customer service line at 1-844-DUROMAX (844-387-6629).
