Description

Zoom on the Sportsman GEN4000DF

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

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in outdoor fairs, festivals or events
  • DIYers who wish to improve their efficiency with tools
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with 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.

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

Regarding its running time, the GEN4000DF, with a 3.6 gallons fuel capacity can operate for around 10 hours at 50% load with a full tank of gasoline (fuel consumption around 0.36 GPH). When using propane, it can run for around 12 hours (on a 20 lbs tank - propane consumption around 0.39 GPH).

Outlets

The control panel features the following 5 AC outlets:

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

It also sports 1 DC outlet: there's a 12V 8A receptacle with which charging your batteries is made easy.

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 device has been designed for tough environments and demanding outdoor use.

The GEN4000DF can be taken anywhere with you, thanks to its weight of 90 lbs. Moreover, its open frame design makes it incredibly easy to grab the frame in order to change its location.

Features

Panel of the Sportsman GEN4000DF

The GEN4000DF's control panel

To help you monitor the GEN4000DF's status and activity, its control panel is equipped with a convenient voltmeter, which provides an easy way to monitor power output anytime.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Sportsman GEN4000DF also is packed along with the following accessories: battery charging cables, propane hose, funnel and tool kit.

Emissions

The Sportsman GEN4000DF 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 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).

  • As far as its dry weight is concerned, the Sportsman GEN4000DF weighs just 90 pounds and thus, it is one of the lighter 3000 to 4000 rated wattage generators. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
  • Since the generator's noise is rated at 69 dBA, it has the roughly average expected noise for a device of similar power. If noise emissions are one of your priorities, you may be interested in the Cat INV4000E, one of the least noisy generators similarly powerful as this one, rated for 51 dBA.
  • As for its autonomy, the GEN4000DF, with an autonomy of around 10 hours at a 50% load, is placed on the low end among the generators of its kind. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000X, reaching around 16 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator has an estimated fuel consumption of roughly 0.36 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.

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.

    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
