Description

Zoom on the Predator 8750

In summary, the Predator 8750 is a powerful portable inverter generator especially useful for:

  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Homeowners in need of an emergency backup power for their essentials
  • Camping and tailgating buffs looking to enhance their experience
  • Professionals who want to be able to deliver results, even during a power failure

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Predator 8750 in use

The Predator 8750

The Predator 8750's design includes a gasoline-fueled 420 cc (12 hp) OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 7,000W and also a peak wattage of 8,750W.

Enjoying a noise rating of 75 dBA (just slightly more noisy than a dishwasher), this inverter generator can be started thanks to a conventional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included).

With a full tank, the 8750 can operate for up to 15 hours (fuel consumption around 0.39 GPH), thanks to its fuel capacity of 5.9 gallons.

Delicate electronics can be plugged in an AC outlets safely, as the 8750 generates a clean sine wave, reaching a <3% Total Harmonic Distortion (THD).

Outlets

The control panel features the upcoming 5 AC outlets:

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

It also sports 3 DC outlets: there's two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently and a 12V 10A receptacle with which you may charge your batteries with ease.

Due to the featured twist-lock L14-30R receptacle, the 8750 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The Predator 8750 has a conventional, open frame design, which offers support and allows it to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 151 lbs. However, this lack of maneuverability is compensated by its set of wheels (⌀10") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Predator 8750

The 8750's control panel

The control panel of the 8750 includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

In addition to this info, when the generator is ready, its oil levels are insufficient and the generator is on overload, you will be informed by the featured light indicators.

Thanks to a built-in fuel gauge, the inverter 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.

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).

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Predator 8750's package also includes these accessories: battery charging cables, funnel and tool kit.

Emissions

The Predator 8750 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, so it is adequate for use in forested areas.

The Predator 8750 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Predator 8750 compare to generators of similar power (between 6500 and 7500 W).

  • Weight-wise, the Predator 8750 has only 151 lbs, which renders it one of the lighter generators which produce 6500 to 7500 rated watts. In terms of weight, one of the champions in their power range is the Sportsman GEN85KIDF, standing at just 133 lbs.
  • Among the generators of a comparable running wattage, this inverter generator with a lowest noise of 75 dBA can be judged as noisy. 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.
  • Offering up to 15 hours of running time on a full tank at 25% load, the 8750 is within the average autonomy range of similarly powerful generators. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Powerhorse 7500i, as it provides up to 16 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This inverter generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.39 GPH (gallon per hour) at 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV8000, with a fuel consumption of 0.35 GPH could be in your good books.
According to our stats, the following comparison is pretty popular: Predator 8750 vs Predator 9500.

Price comparison

As you can see from this interactive chart, when compared to other 6500-7500W inverter generators, the Predator 8750 is on the average side of the price range.

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

    Bought this generator and only used it maybe 15 days. The generator has stopped putting out enough voltage. Harbor Freight is a HORRIBLE company to buy generators from. I am sitting here with this generator and HARBOR FREIGHT cannot tell you how to fix it. DO NOT BUY FROM HARBOR FREIGHT AND DO NOT BUY THIS GENERATOR .

    • Nothing

    • Horrible

    Need a schematic. Price point is excellent as all harbor freight tools are. BUT get what you pay for.mine will not start by Battery.

    + PROS:
    • Good price. Maybe if it will run.
    - CONS:
    • Almost impossible to fill oil. No schematic. Will not start on electric. No idea or part number for alligator clip cable with a angled plug. Have to search for spark plug again as NO SCHEMA TIC

    This is an inverter generator and for the price that is a big selling point, however I don’t understand why they recommend using a surge protector with it. I am using one, but don’t see why it is necessary for an inverter.

    + PROS:
    • BIG plus, this is an INVERTER generator.
    - CONS:
    • Quite noisy, but it is outside my house and acceptable. Manual is not very good and incomplete. Oil fill is slow and will overflow before it is completely full, so it must be filled slowly. Will NOT start if it isn’t full of oil. Esc must be off when starting, but can be turned on after it has started running (will slow engine slightly and reduce noise level). Manual doesn’t mention why there is a cord with alligator clips on one end and what looks like an AC plug on the other (looks really dangerous).

    Like anything if you take care of it,it will take care of you.Did a lot of research on generators the 8750 was a no brainer if you want to add natural gas,propane it can be done easily.Other predator older model 9000 is still going strong for 551 bucks try to beat that.

    + PROS:
    • Quieter than older model runs great
    - CONS:
    • Warranty HF should give at least a year warranty with the price of this unit

    Just bought one today. Had a problem with a bad vendor on the champion version 100520. Have a Honda eu2000 with 550 hours, zero problems, regular maintenance. Needed to power well pump, fridge,freezer, etc. Not for hvac or water heater. Started up great. Nice idle control, about as loud as a riding mower when running close to 7000 watts. Running a 30 amp transfer to main.

    + PROS:
    • Cost effective inverter.
    - CONS:
    • Can be a little loud.(It's not a Honda,lol)
