Power & Run Time

The Sportsman GEN4000DF-SS in use

The Sportsman GEN4000DF-SS

With its dual-fuel technology, the powerful and versatile Sportsman GEN4000DF-SS provides an output of 120V. While gasoline-powered, it gives a running wattage of 3500W along with a peak wattage of 4000W. While propane-powered, it provides 3100 rated watts and 3600 starting watts.

With a noise rating of 69 dBA (less noisy than a normal conversation), the generator features a conventional pull-start mechanism.

The GEN4000DF-SS, with a fuel capacity of 3.9 gallons, reaches a run time of around 10 hours at 50% load utilizing gasoline (fuel consumption around 0.39 GPH). Alternatively, it can reach a run time of around 12 hours (on a 20 lbs tank - propane consumption around 0.39 GPH) with propane.

Outlets

The control panel provides the upcoming 5 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

Additionally, it features 1 DC outlet: there's a 12V 8A receptacle with which charging your batteries is made easy.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Sportsman generator is RV Ready.

Portability

The design of the Sportsman GEN4000DF-SS is a typical, open frame, with the dimensions of L23 x W19.5 x H17.5 in, offering support and stability and enabling the possibility of raising it above ground level. The featured design is ideal for the outdoors and all tough environments.

The 91 lbs of the GEN4000DF-SS's dry weight enables you to use it anywhere you will ever need. In addition, it is even easier to grab and move the generator around thanks to its open frame design.

Features

The GEN4000DF-SS's control panel

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Sportsman GEN4000DF-SS also comes with some accessories: propane hose, battery charging cables, tool kit and funnel are included.

Emissions

The Sportsman GEN4000DF-SS is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor and thus, may be used in forested areas.

Product Video

The Sportsman GEN4000DF-SS versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Sportsman GEN4000DF-SS compare to generators of similar power (between 3000 and 4000 W).

  • As for its weight, the Sportsman GEN4000DF-SS weighs only 91 pounds, making it one of the lighter generators in the 3000-4000 rated wattage category. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
  • This generator has a somewhat average expected noise for its power range, rated at 69 dBA. If you are concerned with noise, check out the Cat INV4000E, which is one of the least noisy generators in its power range, with a noise rating of just 51 dBA.
  • The GEN4000DF-SS’s autonomy is somewhat low end compared to devices of its power range, as it reaches only around 10 hours at 50% load on a full tank. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000X, as it provides around 16 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.39 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W generators, the Sportsman GEN4000DF-SS is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
