Description

Zoom on the Sportsman GEN4000DF-SS

In a nutshell, the Sportsman GEN4000DF-SS is a compact portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • DIYers who wish to improve their efficiency with tools
  • Homeowners in need of an emergency backup power for their essentials

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

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 simple traditional pull-start mechanism.

As for its running time, the GEN4000DF-SS, along with its 3.9 gallons fuel capacity, can run for around 10 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.39 GPH). If propane is used, it can operate for around 12 hours (on a 20 lbs tank - propane consumption around 0.39 GPH).

Outlets

The control panel includes the following 5 AC outlets:

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

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

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Sportsman generator is RV Ready.

Portability

The Sportsman GEN4000DF-SS has the following dimensions: L23 x W19.5 x H17.5 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

The 91 lbs of the GEN4000DF-SS's dry weight enables you to use it anywhere you will ever need. Moreover, its open frame design makes it incredibly easy to grab the frame in order to change its location.

Features

The GEN4000DF-SS's control panel

From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

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: battery charging cables, funnel, propane hose and tool kit 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, making it usable 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 far as its dry weight is concerned, the Sportsman GEN4000DF-SS weighs just 91 pounds and thus, it is one of the lighter 3000 to 4000 rated wattage generators. 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.
  • The generator can be considered average in its noise for its power category, as it is rated at 69 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the Cat INV4000E with only 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. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 4375, reaching around 16 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.39 GPH. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.

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.

Can it be converted to natural gas instead of propane? (Asked August 11, 2020)

There are no official conversion kits. You may find non-officials. However, we do not recommend such modification. In addition to potentially voiding your warranty, you could also be breaking your local emission laws.

    Great machine weather in a power outage for days and weeks. To using camping or just backyard fun. I live in the Florida panhandle which sees alot of severe storms and tropical storms and hurricanes. Plus a tornado once in awhile. So this generator is a must and starts up with one pull usually. Thanks Buffalo Corp.

    + PROS:
    • It's powerful to run all my important things when we lose power at home. It runs pretty quiet compared to other name brands.
    - CONS:
    • It should come with wheel and handle kit.
