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
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • DIYers who wish to improve their efficiency with tools
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Sportsman GEN4000DF in use

The Sportsman GEN4000DF

Thanks to its dual-fuel technology, the Sportsman GEN4000DF delivers 120V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3500W and a peak wattage of 4000W. When propane-powered, it has 3100 rated watts and 3600 peak watts.

The generator features a simple traditional pull-start mechanism. It is rated for a noise of 69 dBA (less noisy than background music).

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

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

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

Portability

The Sportsman GEN4000DF has a conventional, open frame design, of the following dimensions: L24.5 x W17 x H16.5 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

As the GEN4000DF's weight is only 90 lbs, it can follow you and your power needs anywhere. Additionally, the generator’s mobility is also improved by its open frame design, as it can be easily grabbed and shifted.

Features

The GEN4000DF's control panel

The GEN4000DF's status and activity may be monitored conveniently via the control panel, as it features a convenient voltmeter, which provides an easy way to monitor power output anytime.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

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: tool kit, propane hose, funnel and battery charging cables.

Emissions

The Sportsman GEN4000DF is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used in forested areas.

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).

  • In terms of its dry weight, the Sportsman GEN4000DF stands at only 90 lbs, meaning that is one of the lighter devices of the 3000-4000 rated wattage category In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
  • The generator can be considered average in its noise for its power category, as it is rated at 69 dBA. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Cat INV4000E, whose lowest noise levels reach just 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 you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Honda EB4000X, with 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. This generator reaches an estimated fuel consumption of 0.36 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.

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
