The Sportsman GEN4000-SS has an OHV 4-stroke engine with 212 cc and 7 hp that runs on gasoline. It has a 120V output and a running power of 3,500W and a peak power of 4,000W. The generator has a noise level of 69 dBA, which is less than an office. It is started with a simple pull-start mechanism. With a full tank, the GEN4000-SS can run for about 10 hours at 0.5 load on its 3.9-gallon fuel tank (fuel consumption is approximately 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.Also, it has 1 DC outlet, which is 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”).
When it comes to safety, this product has a circuit breaker for overheating and an automatic shut-off for low oil, so you can use it without any worries.The Sportsman GEN4000-SS comes with basic instructions and an owner’s manual that will help you start the generator quickly.It also comes with a funnel, a tool kit, and battery charging cables.
The Sportsman GEN4000-SS is 23 inches long, 19.5 inches wide, and 17.5 inches high.Together with its traditional, open-frame design, they support the generator and allow it to be raised above the ground.The generator is built to work well outside and in rough places.With a dry weight of 91 lbs, the GEN4000-SS’s power can be used anywhere.The open frame design of this product also makes it easier to grab and move.
We could find any videos of the product at the time of writing. Please search YouTube for any update.

- 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.
