Description

Powered by a reliable Predator gas engine, this generator is ideal for emergencies, job site use, recreation, household, lawn and garden, heating and cooling.

Zoom on the Predator 4000

In a nutshell, the Predator 4000 is a compact portable generator mostly geared towards:

  • 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 in need of an emergency backup power for their essentials
  • Professionals who want to ensure that a power failure will not prevent them from working

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Predator 4000 in use

The Predator 4000

The Predator 4000's engine, 212 cc (6.5 hp) OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 3200W and reaches a peak wattage of 4000W.

At a noise rating of 72 dBA (just slightly more noisy than a vacuum cleaner), the generator is started via a simple traditional pull-start mechanism.

The 4000 can operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.4 GPH), due to its fuel capacity of 4 gallons.

Outlets

The control panel includes the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

In addition, it provides 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease.

Due to the featured twist-lock L14-30R receptacle, the 4000 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The Predator 4000 has the following dimensions: L23.3 x W18.7 x H19.3 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

The 4000's dry weight of 99.5 lbs lets you use its power anywhere needed. Furthermore, the open frame of the generator further helps when holding and moving it to a different place.

It is also possible to purchase a wheel kit, such as this one (opens in a new tab), to help you transport this unit more easily.

Features

Panel of the Predator 4000

The 4000's control panel

The device’s light indicator will display if its oil levels are insufficient.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

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 features previously mentioned, accessory-wise, the Predator 4000 comes with the usual documentation and owner's manual (opens in a new tab) needed to get you promptly started.

Emissions

The Predator 4000 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, making it usable in forested areas.

The Predator 4000 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Predator 4000 compare to generators of similar power (between 2500 and 3500 W).

  • At a weight of 99.5 pounds, the Predator 4000 places in the expected weight range of the generators in the 2500-3500 rated wattage range. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • Among the generators of a comparable running wattage, this generator with a lowest noise of 72 dBA can be judged as noisy. 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 Honda EU3000iS, whose lowest noise levels reach just 50 dBA.
  • As the 4000 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 Honda EB4000X, with 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.4 GPH 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.

Here's a list of the most popular specific comparisons:

The bottom line

STRENGTHS:
  • GFCI Outlets
AVERAGE SPECS:
  • Decent weight (99.5 lbs)
  • Decent run time
WEAKNESSES:
  • No data center
  • No electric start
  • Weak warranty
  • On the noisy side (72 dBA)
  • Low fuel efficiency

    i have had a predator 400 for about 4 years. however at this time, the plugs do not work, the resets do not work and when the front panel was taken off to be looked at, the plug casing was broken, only on one side, the other side was cracked. teh resets were replaced, but that did not solve the problem. i have been thru 2 hurricanes and a couple of other power outages. i work on fence lines and where i go hunting. great tool. i need the panel or i hve a 99.5 pound noise maker. can you help me

    + PROS:
    • handy,
    - CONS:
    • susceptible to rust

    I’ve had my Predator 4000 for about 3 years and it has done it’s job each time. I’ve had 3 significant power outages, one lasted 2+ days. If you run it as recommended and take time to perform PM on it it’s a nice unit to save your frozen goods plus a few lights and TV.

    + PROS:
    • Does it's job as advertised.
    • Simple to operate.
    - CONS:
    • A little noisy.
