Description
The Sportsman GEN4000DF-SS has a 120V output and great power and versatility thanks to its dual-fuel technology. If it is powered by gasoline, the device has a running power of 3,500W and a starting power of 4,000W. If it runs on propane, it has a rated power of 3100 watts and a starting power of 3600 watts. The generator is meant to make 69 dBA of noise (a little lower than background music). It uses a simple, traditional pull-start mechanism to get going. With a fuel capacity of 3.9 gallons, the GEN4000DF-SS can run for about 10 hours at 0.5 load with a full tank of gasoline (fuel consumption is approximately 0.39 GPH). If propane is used, it can run for about 12 hours (on a 20 lbs tank – propane consumption around 0.39 GPH).
Outlets
The control panel has 5 AC outlets, which are as follows: Two 120V 20A (5-20R) and 120V 30A (TT-30R) duplex plugs.
Also, it has 1 DC outlet, which is a 12V 8A receptacle that makes it easy to charge your batteries.The TT-30R plug on this Sportsman generator is ready for an RV.TT stands for “Travel Trailer”.Features
When it comes to safety, this product has an automatic low oil shut-off and an overload protection (circuit breaker), so you can use it without worry.
The Sportsman GEN4000DF-SS package comes with basic paperwork and an owner’s manual that will help you start the generator right away.It also comes with a propane hose, battery charging cables, a funnel, and a tool kit.Mobility
The Sportsman GEN4000DF-SS has a standard, open frame that measures L23 x W19.5 x H17.5 in, This frame gives it support and lets it be raised off the ground.
The design shown is great for the outdoors and other rough places.The GEN4000DF-SS is easy to take with you wherever you need power because it weighs only 91 pounds when it’s dry.Also, the generator’s open frame makes it easier to hold and move from one place to another.Product Videos

- 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.
