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
  • People occasionally participating in outdoor fairs, festivals or events
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

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 is powered by a 212 cc (7 hp) OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3500W as well as a peak wattage of 4000W.

At a noise rating of 69 dBA (less noisy than an office), the generator is started via a conventional 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 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.

This Sportsman generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The Sportsman GEN4000 has a conventional, open frame design, of the following dimensions: L23 x W19.5 x H17.5 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.

With a dry weight of 91 lbs, the GEN4000 can easily follow you wherever your power needs are. Moreover, grabbing and moving this product is made even easier by its open frame design.

Features

Panel of the Sportsman GEN4000

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.

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).

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).

  • 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. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 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 important to you, one of the least noisy generators of this power range is the Cat INV4000E with only 51 dBA.
  • As far as autonomy is concerned, providing around 10 hours of runtime with a full tank at a 50% load, the GEN4000 falls into the low end in comparison with other devices of a comparable power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Predator 4375, as it provides around 16 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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 fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.

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:
  • Acceptable noise (69 dBA)
  • Decent fuel efficiency

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.
