Description
The Sportsman GEN4000 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. This generator has a noise level of 69 dBA, which is less than a normal conversation. It starts up with a simple pull-start mechanism. With a full tank, the GEN4000 can run for about 10 hours at 0.5 load (using about 0.36 GPH of fuel). This is because it has a 3.6-gallon fuel capacity.
Outlets
The control panel has 5 AC outlets, which are as follows: 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”).
Features
The status and activity of the GEN4000 can be easily checked on the control panel, which has a voltmeter that makes it easy to check power output at any time. 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 Sportsman GEN4000 package comes with basic paperwork and an owner’s manual that will help you start the generator right away. It also comes with a tool kit and battery charging cables.
Mobility
The Sportsman GEN4000 has a typical open frame that is 23 inches long, 19.5 inches wide, and 17.5 inches high. This gives it support and stability and gives you the option of raising it off the ground. The device was made to work well in harsh conditions and in the great outdoors. The GEN4000 is 91 pounds, which means you can take it anywhere. Also, the open frame makes it very easy to grab the frame and move it.

- 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.
