The powerful and versatile Sportsman GEN4000DF gives off 120V thanks to its dual-fuel technology. Even though it runs on gasoline, it has a running wattage of 3,500W and a peak wattage of 4,000W. It runs on propane and has a rated power of 3100 watts and a starting power of 3600 watts. The generator has a simple pull-start mechanism that has been used for a long time. It has a noise level of 69 dBA (quieter than a regular conversation). With a fuel capacity of 3.6 gallons, the GEN4000DF can run for about 10 hours at 0.5 load with a full tank of gasoline (fuel consumption is approximately 0.36 GPH). If propane is used, it can run for about 12 hours (on a 20 lbs tank – propane consumption around 0.39 GPH).
On the control panel, there are 5 AC outlets for: Two 120V 20A (5-20R) and 120V 30A (TT-30R) duplex plugs.It also has 1 DC outlet: a 12V 8A receptacle that makes it easy to charge your batteries.This Sportsman generator is ready for an RV because it has a TT-30R plug (TT stands for “Travel Trailer”).
The GEN4000DF’s control panel has a voltmeter that makes it easy to check the power output at any time.This is helpful for keeping track of its status and activity.For safety, the generator has an overload protection (circuit breaker) and an automatic low oil shut-off, so you can use it without worrying.The Sportsman GEN4000DF comes with the usual paperwork and an owner’s manual , which lets you start it right away.It also comes with a propane hose, tool kit, funnel, and battery charging cables.
The Sportsman GEN4000DF has a traditional, open frame design with dimensions of L24.5 x W17 x H16.5 in, This gives the generator stability and lets it be raised above ground level.This type of design is great for tough environments and heavy outdoor use.Since the GEN4000DF weighs only 90 lbs, you can take it anywhere you need power.The generator is also easier to move because it has an open frame, which makes it easy to grab and move.
The following charts show how some of the most important features of the Sportsman-GEN4000DF 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.
