Description

Zoom on the Sportsman GEN4000

In a nutshell, the Sportsman GEN4000 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
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners in need of an emergency backup power for their essentials

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 GEN4000 in use

The Sportsman GEN4000

The Sportsman GEN4000 houses a 212 cc (7 hp) OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3500W along with a peak wattage of 4000W.

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

Thanks to a fuel capacity of 3.6 gallons, the GEN4000 can operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.36 GPH).

Outlets

The control panel includes 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, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

With its dimensions of L23 x W19.5 x H17.5 in, the conventional, open frame design of the Sportsman GEN4000 offers stability and allows the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

The GEN4000's dry weight of 91 lbs lets you use its power anywhere needed. Moreover, its open frame design makes it incredibly easy to grab the frame in order to change its location.

Features

The GEN4000's control panel

The control panel of the GEN4000 includes a handy voltmeter that allows you to easily monitor power output anytime, helpful for 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.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Sportsman GEN4000 also is packed along with the following accessories: battery charging cables and tool kit.

Emissions

The Sportsman GEN4000 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

The Sportsman GEN4000 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Sportsman GEN4000 compare to generators of similar power (between 3000 and 4000 W).

  • As far as its dry weight is concerned, the Sportsman GEN4000 weighs just 91 pounds and thus, it is one of the lighter 3000 to 4000 rated wattage generators. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • This generator has a somewhat average expected noise for its power range, rated at 69 dBA. 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 GEN4000, 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.
  • 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 average fuel consumption among comparably powerful devices, as it reaches 0.36 GPH (gallon per hour) at a 50% load. 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 GEN4000 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.
