Powered by a dependable 420cc PREDATOR® gas engine, this generator is ideal for emergencies, job-sites, and home backup.

Zoom on the Predator 9000

In a nutshell, the Predator 9000 is a portable generator mostly geared towards:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • 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
  • RV travellers who wish to upgrade their experience to another level

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 9000 in use

The Predator 9000

The Predator 9000's design includes a gasoline-fueled 420 cc (13 hp) OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 7250W and also a peak wattage of 9000W.

The generator features a conventional pull-start mechanism and also a simple and elegant electric starter (battery not included). It is rated for a noise of 73.5 dBA (just slightly more noisy than a shower).

Thanks to a fuel capacity of 8 gallons, the 9000 can operate for around 13 hours at 50% load with a full tank (fuel consumption around 0.62 GPH).


The control panel features the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

It also sports 1 DC outlet: there's a 12V 10A (cigarette lighter style) receptacle with which charging your batteries is made easy.

This Predator generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor. Besides, as it features a twist-lock L14-30R receptacle, the 9000 is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.


The design of the Predator 9000 is a typical, open frame, with the dimensions of L26.9 x W22 x H22.8 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.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 195 lbs make it incredibly difficult to manually lift and transport. Nevertheless, thanks to a wheel kit (separate purchase from Harbor Freight or Amazon), the generator can be easily moved, once placed on the ground.


Panel of the Predator 9000

The 9000's control panel

A light indicator shows you if its oil levels are insufficient.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

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.

The unit also benefits from the Predator's CO SECURE™ carbon monoxide detection. This system monitors the accumulation of CO gas while the generator is running and will shut off the engine if the levels become dangerously high. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Besides the features previously mentioned, accessory-wise, the Predator 9000 comes with the usual documentation and owner's manual (opens in a new tab) needed to get you promptly started.


The Predator 9000 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

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

The unit also meets the ANSI/PGMA G300-2018 safety and performance requirements.

The Predator 9000 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Predator 9000 compare to generators of similar power (between 6500 and 7500 W).

  • As its weight is 195 pounds, the Predator 9000 falls in the expected weight range of the devices in the 6500-7500 rated wattage category. If you are concerned by weight, one of the champions in the above-mentioned power range is the Sportsman GEN85KIDF, with a dry weight of just 133 pounds.
  • Since the generator's noise is rated at 73.5 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 Powerhorse 7500i with only 55 dBA.
  • The 9000 provides a higher run time than similarly powerful devices, reaching around 13 hours at 50% load. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Generac XC6500E, as it provides around 14 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. This generator has an estimated fuel consumption of roughly 0.62 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If fuel consumption is your top priority, we suggest to check out the Lifan ESI 7000iER-EFI, which has a fuel consumption of only 0.38 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 6500-7500W generators, the Predator 9000 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

The bottom line

  • In the expected price range
  • CO SECURE™ technology
  • GFCI Outlets
  • Electric start
  • High run time
  • Decent weight (195 lbs)
  • Acceptable noise (73.5 dBA)
  • Decent fuel efficiency
  • No data center
  • No 50-amp output
  • Battery not included
  • No remote start
  • Wheel kit not included
  • Weak warranty

    I purchased the predator 9000 for whole house back up power. It’s doing a real good job. When the power goes off, we just keep on as usual. I do refill it every 8 hrs, to insure no surges because of fuel loss. It’s a real good product.

    + PROS:
    • Since I don't have to move it around, I like it being heavy. It has a automatic voltage regulator.
    - CONS:
    • No battery included

    Bought the 9,000 preditor generator at harbor freight this week. Was on sale and with a coupon was $590 with taxes and that included a wheel kit. Very heavy unit but so far please with it for the price.

    + PROS:
    • Very affordable.
    • Bought it on sale, with coupon, this week for $590 out the door with wheel kit.
    • Runs most of my house.
    • Not any louder than my other generator of the same size with a load.
    - CONS:
    • Very heavy.
    • No battery included.
    • Loud without a load on it.

    I was able to talk my wife into purchasing the Predator 9k while sitting in the dark, under every blanket in the house, and shivering with our young children during the ice storm last October here in Oklahoma. As soon as the power came on, I placed my order w/ HF. The gennie arrived sometime December, and was broken-in and ready to keep us warm and entertained during the frozen hell that was February ’21. Aside from having to wake up to feed it, and getting stuck in snow drift to refuel jerry cans, my winter hunker was lovely.
    This year, I asked her to buy me(us) a natural gas kit for the gennie. It arrived last week, ya’ll can come over if you get cold. I also installed the battery, because it was cold enough that the oil was starting to jell.
    I love my wife.
    Maybe next year she’ll get me (us) a transfer switch installed.

    + PROS:
    • All the power we need
    • Easy pull start, when warmer than -10F
    • 230lb anti-theft device.
    • Electric start for a few dollars more.
    • I couldn't be happier!
    - CONS:
    • VERY loud with no load
    • Clumsy to maneuver on soft ground.
    • It's red and black, should be orange and black.
    • It wasn't free.

    Bought this generator for Hurricane Ida. Initially was sold the wrong battery so starting was iffy. After I switched to the correct battery, starting was smooth and quick. This generator is very quiet. When I stand in my front yard I can hear all the generators operating in the neighborhood but I can not hear mine. Neighbors ask if I have a generator since you can not hear it street side of my house. Sitting inside the house, I can barely hear the generator. The window a/c unit makes more noise than the Predator 9000. I am using regular gasoline and adding some octane boost to get a longer run time. Running all the lights, TV, refrigerator, 12000 BTU window unit, fans and only using a bit over 5 gallons of gas every 12 hrs. Very efficient.

    + PROS:
    • Quiet
    • Long run time
    • Easy to start
    - CONS:
    • No wheel kit
    • No battery
    • The cost of the generator is $749 (+ tax). Which makes it much cheaper than other 9000 Watt generators. After adding the $225 for battery & wheel kit price is comparable but still less than other 9000's.

    I bought a returned unit and somewhat happy so far. It doesnt like the surge of my well pum.i was running 2 fridges and 3 LED lights. When the pump kicked on the lights shut off or dimmed. It should have been well within the 9000 watt surge.

    + PROS:
    • Fairly easy to move.
    • Very easy to start.
    • Both a 240 and 120 volt hook up for power panel
    • Quiet for a generator in its.power class

    My gas tank took 5 gallons although I believe it should hold 6 gallons. 8 gallons? Where did that come from? Other than way too noisy it is a very good generator that I use for home back up. Heavy yes but OK with wheel kit. Get the battery it’s only 30 to 40 dollars. The warranty is only 90 days unless you buy the 2 year warranty at around 100 bucks. Even with these add ons price is unbeatable.

    + PROS:
    • Inexpensive, but well made.
    - CONS:
    • very loud. I put mine in a quiet box that I constructed and the sound right next to the box is 70-72 dba,
