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 sporting competitions, open-air performances and outdoor festivals
  • Amateur DIY lovers
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • 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 design includes a gasoline-fueled 212 cc (6.5 hp) OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 3200W and also a peak wattage of 4000W.

The generator features a conventional pull-start mechanism. It is rated for a noise of 72 dBA (just slightly more noisy than a dishwasher).

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

Outlets

The control panel includes the following 5 AC outlets:

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

Furthermore, it has 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle allowing you to easily charge your batteries.

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 design of the Predator 4000 is a typical, open frame, with the dimensions of L23.3 x W18.7 x H19.3 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough environments and demanding outdoor use.

The 4000's dry weight of 99.5 lbs lets you use its power anywhere needed. Moreover, grabbing and moving this product is made even easier by its open frame design.

To make this unit even more maneuverable, an extra wheel kit, such as this one (opens in a new tab), could be an excellent solution.

Features

A light indicator shows you 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 automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

As for its accessories, apart from the previously mentioned features, the Predator 4000 also comes with the basic documentation and an owner's manual (opens in a new tab), allowing you to start it right away.

Emissions

The Predator 4000 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 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).

  • Having a dry weight of 99.5 lbs, the Predator 4000 belongs in the expected weight range for generators which produce 2500 to 3500 rated watts. If weight matters to you, one of the champions in this power range is the Genmax GM3300i with only 47.4 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.
  • The 4000, 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 autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 4375, reaching 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 is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.4 GPH at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.22 GPH, the Genmax GM3300i is a device you could look out for.

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

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W generators, the Predator 4000 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
  • 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’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.
