Description

Zoom on the Sportsman GEN4000DF

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

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Amateur DIY lovers
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

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 in use

The Sportsman GEN4000DF

With its dual-fuel technology, the powerful and versatile Sportsman GEN4000DF 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.

At a noise rating of 69 dBA (less noisy than a normal conversation), the generator is started via a simple traditional pull-start mechanism.

With a fuel capacity of 3.6 gallons, the GEN4000DF can operate for around 10 hours at 50% load using gasoline (fuel consumption around 0.36 GPH), or for around 12 hours (on a 20 lbs tank - propane consumption around 0.39 GPH) using propane.

Outlets

The control panel features the following 5 AC outlets:

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

In addition, it provides 1 DC outlet: there's a 12V 8A receptacle with which you may charge your batteries with ease.

This Sportsman generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

With its dimensions of L24.5 x W17 x H16.5 in, the conventional, open frame design of the Sportsman GEN4000DF offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

The GEN4000DF can be taken anywhere with you, thanks to its weight of 90 lbs. Furthermore, the open frame of the generator further helps when holding and moving it to a different place.

Features

Panel of the Sportsman GEN4000DF

The GEN4000DF's control panel

The GEN4000DF's control center features a handy voltmeter that allows you to easily monitor power output anytime to aid you with the monitoring of its status and activity.

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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Sportsman GEN4000DF, the following accessories are also included: tool kit, propane hose, battery charging cables and funnel.

Emissions

The Sportsman GEN4000DF is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.

Product Videos

The Sportsman GEN4000DF versus other generators

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

  • Weight-wise, the Sportsman GEN4000DF has only 90 lbs, which renders it one of the lighter generators which produce 3000 to 4000 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • Because this generator emits noise as low as 69 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. 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.
  • Autonomy-wise, with around 10 hours on a full tank at a 50% load, the GEN4000DF is on the low end when compared to other generators of a similar power output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000X, boasting with around 16 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. Standing at an estimated 0.36 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. 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 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.

Does this model of generator need a battery as it looks like it doesn't come with one. (Asked November 12, 2020)

No battery is indeed, since the unit is recoil start only.

    I made the purchase of this generator from Home Depot for a very reasonable price. I used it the first time at my home when the electric failed for two days it powered my electric furnace, my refrigerator, lights and the micro-wave everything preformed with-out a problem I’m very impressed with the unit, I also use it to power my travel trailer with camping at non-electric sites and it works wells to keep the A/C on the trailer running to stay comfortable this 3500 watt generator will power about anything your attached to it. One needs to be cautious when running multiple items to run at the same time example when running a A/C run it it at a low speed so to keep the wattage draw at a min. Its all about common sense

    + PROS:
    • Fantastic Unit. It also runs on propane I use a 20 lb cyl. Other tanks are avail for more capacity of propane I would think this unit would be perfect for a hunter or a fisherman
    - CONS:
    • Needs a bigger fuel tank if using gas and its not real noisy when running
