Description

Zoom on the Sportsman GEN4000

In a nutshell, the Sportsman GEN4000 is a compact portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor 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

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'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.

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

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

Outlets

The control panel features the upcoming 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 allowing you to easily charge your batteries.

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

Portability

The design of the Sportsman GEN4000 is a typical, open frame, with the dimensions of L23 x W19.5 x H17.5 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.

As the GEN4000's weight is only 91 lbs, it can follow you and your power needs anywhere. 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 GEN4000 and its control panel include a handy voltmeter that allows you to easily monitor power output anytime. This feature comes handy when monitoring its status and activity.

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

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.

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).

  • As for its weight, the Sportsman GEN4000 weighs only 91 pounds, making it one of the lighter generators in the 3000-4000 rated wattage category. If weight matters to you, one of the champions in this power range is the Genmax GM3300i with only 47.4 pounds.
  • This generator, with its lowest possible noise rated at 69 dBA falls into the more noisy category, compared to other devices of a similar running wattage. If noise emissions are important to you, one of the least noisy generators of this power range is the Cummins Onan P4500i with only 52 dBA.
  • The GEN4000, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 10 hours at a 50% load and a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Predator 4375, boasting 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. 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 you wish to acquire one of the most gasoline efficient products of this power range, the Genmax GM3300i, with a fuel consumption of 0.22 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.

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.

    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!!!

    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.
