Description

Zoom on the Sportsman GEN4000

In summary, the Sportsman GEN4000 is a compact portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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 GEN4000 in use

The Sportsman GEN4000

The Sportsman GEN4000's core is the 212 cc (7 hp) OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3500W and a peak wattage of 4000W.

The generator features a conventional pull-start mechanism. It is rated for a noise of 69 dBA (less noisy than a normal conversation).

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 provides the upcoming 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 charging your batteries is made easy.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Sportsman generator is RV Ready.

Portability

The Sportsman GEN4000 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 featured design is ideal for the outdoors and all tough environments.

With a dry weight of 91 lbs, the GEN4000 can easily follow you wherever your power needs are. Furthermore, the open frame of the generator further helps when holding and moving it to a different place.

Features

Panel of the Sportsman GEN4000

The GEN4000's control panel

The GEN4000'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.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Sportsman GEN4000 also comes with some accessories: battery charging cables and tool kit are included.

Emissions

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

Product Videos

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).

  • Regarding its weight, the Sportsman GEN4000 only weighs in at 91 pounds, which means it's one of the lighter generators in the 3000-4000 rated wattage range. In terms of weight, one of the champions in their power range is the Genmax GM3300i, standing at just 47.4 lbs.
  • This generator, with its lowest possible noise rated at 69 dBA falls into the more noisy category, compared to other devise of a similar running wattage. 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 the GEN4000 offers around 10 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. 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 Predator 4375, with around 16 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency 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 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 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.

The bottom line

STRENGTHS:
  • Inexpensive
  • Several accessories included
  • RV Ready
  • Lightweight for its kind (91 lbs)
AVERAGE SPECS:
  • Decent run time
  • Decent fuel efficiency
WEAKNESSES:
  • No electric start
  • Not CARB-compliant
  • No spark arrestor
  • 1-year warranty
  • On the noisy side (69 dBA)

What is the difference between a generator with an inverter and without we’re going camping I just ordered the Sportsman 3500/4000 gas only? (Asked October 30, 2020)

The biggest difference is that an inverter generator allows for a safe powering of equipment that contains sensitive electronics. Inverter generators are also less noisy, and more fuel efficient. You can read more about it in this article.

    Generator has had problems since the minute I started using it. First of all it don’t run no 10 hours on a full tank of gas
    It runs about 5 hours. I was charging a cell phone and running a lamp and a portable heater and filling the gas tank every 5 hours .The next day I fill the oil to overflowing just like the directions say ( not to mention not easy to fill when you have to tip the Generator halfway on its side to fill it or the oil spills out) and I run it for about 2 hours. Charging a cell phone and running a lamp. The next day the dam thing blows up on me. I’m thinking wtf was that? Oil is coming out from underneath the generator . I have had this generator for about a week. I’m so freaking mad!!!! I better get a refund for this.

    + PROS:
    • Easy to operate. Even for a woman.
    - CONS:
    • Expensive to run. Goes through too much gas and oil.

    DO NOT BUY!! Spend a few extra bucks and get a more dependable generator. Having too many issues with this generator, less than 3 months old and less than 100hrs run time

    + PROS:
    • Good price, nothing else good to say about it.
    - CONS:
    • On my 3rd plug wire/coil as design flaw with sparkplug boot as it went into side instead of thru top like 99% of normal plugs. Unable to use a week at a time waiting for parts. 3rd one FINALLY redesigned to send wire thru top of plug boot. Choke switch very loose, would try to engage due to motor vibration causing motor to almost stall. Had to rig a tie off after start to hold choke switch in off position. DO NOT BUY!!!
