Predator 8750 Generator Review 2024

The Predator brand is famous for its affordable and reliable generators. Harbor Freight Tools is the company behind the Predator series generators. It is a trusted brand for generators.

While there is an older Predator 8750 watts model with fewer features, Harbor Freight has come up with a newer 8750-watt generator. Their newer model is more expensive but comes equipped with CO-SECURE technology which makes operating the generator safer since CO-SECURE causes it to shut down automatically when it detects harmful levels of carbon monoxide. This is particularly useful for those who use their generators for long periods.

Let’s take a look at some of the design changes and features of the older and newer models.


The Predator 8750 is a high-end inverter generator. It has a built-in inverter that protects sensitive appliances like refrigerators. It comes with a power capacity of 7,000 running watts and 8,750 peak watts. For this price range, it has great power capacity.

This model can be used in construction sites and at home as a power backup. Most home appliances need a starting wattage of at most 3,000 watts which fits into the Predator 8750 generator’s capacity. It makes the generator suitable for running many high voltage devices at once which is unimaginable in most generators.

The engine is a 420cc air-cooled OHV gas engine. It has 13 horsepower, stays cool, gives a cleaner performance, and lasts longer too. When it comes to Predator engines, reliability and affordable prices often go hand in hand.

The manufacturing company advertises a 12-hour runtime for the Predator 8750 when operating at 50% capacity but we found the runtime extends to 24 hours if you operate it at less than half of its capacity.


The Predator 8750 is a gas-type fuel generator and runs on 87+ unleaded gasoline. Again, the auto-shutdown feature also works when it detects low oil levels and turns the engine off.

With this generator, you get a 6.6-gallon tank that consumes 0.55 gallons of fuel per hour. If fuel efficiency is what you’re looking for, then the Predator 8750 is a solid choice.

Noise Level

When it comes to noise level, the 8750 is a noisy generator. It has a noise level of 76 decibels from a distance of 7 meters. That’s the noise of a vacuum cleaner or radio. The noise isn’t irritating at first, but prolonged exposure can damage your hearing.

If you’re using this generator as a backup or on construction sites, then 76 decibels is manageable. If you plan to keep it running at night, then say goodbye to a peaceful night’s sleep.

Weight and Portability

Weight is one of the biggest issues with this generator. At 183 pounds, this is not a generator you can lift and fit into your RV. When you add its fuel tank to the weight, the total weight of this generator will be around 220 pounds.

In the older model, we found it strange that the manufacturer didn’t add any wheels or handles to make it more portable. The only way to make it more portable is by adding a set of wheels to it. Thankfully, this issue doesn’t exist in the new Predator 8750 model. It now comes with 10-inch flat-free wheels and a folding handle to make it easier to carry around.

Safety Features

This generator includes circuit breakers, an air-cooled engine, low oil alert, and auto shutdown. These features help the generator run steadily and also alert the user in case a problem arises. The fuel shut-off feature keeps your fuel consumption low while protecting the engine from damage. Its circuit breakers are UL (Underwriters Laboratories) listed. This means that your low-voltage devices are protected from receiving too much power.

Want more features? The Predator 8750 doesn’t disappoint. The engine in this generator has shock-absorbing mounts preventing the generator from rattling too much and also reduces the noise created by its vibrations.

It also has a high-quality air filter with thick foam insulation. An air filter might seem like a minor addition but in the long term, we find it very useful since it prevents dirt from entering the fuel tank and increases the life of your generator’s engine.

One drawback of this generator is it doesn’t come equipped with a spark arrestor so that’s an additional expense you’ll have to factor in.


The Predator 8750 has an all-steel body encapsulated by a steel frame that protects it from damage.


The 8750’s gasoline-powered engine is easy to operate. All controls are located on one side of the generator and properly labeled. To start the Predator 8750 generator, you only need to pull on its ripcord and the engine roars to life.

This is a portable electric generator that also comes with a battery-powered starter. The old and new models don’t come with batteries which we thought was a hassle.

LCD Meters

There are no screens or meters for fuel tracking or alerts on the old 8750-watt model. It was a surprise since all Predator generators have display meters, especially the generator models with lower wattages.

At this price range, it seems a waste to not include an LCD fuel gauge as most generators have them. Although the second model has a display meter, we couldn’t understand why the first one didn’t.

The new Predator 8750-watt generator has an integrated digital display that shows you the total hours, frequency, voltage, and more. Along with a digital meter, the new generator also has indicator lights. These were a great help when the generator shut off abruptly and we couldn’t figure out why. The indicator lights helped us quickly identify what the problem was since they warn you against low oil levels, output, and overload.


The maintenance needs of this generator are low compared to other brands. The only upkeep it needs is keeping the engine and the fuel tank clean to prevent engine damage caused by leftover gasoline.


The Predator 8750 watt generator features a good number of outlets for various purposes. These include:

  • Two 120V three-prong 20 amp duplex outlets
  • One 240V four-prong 30 amp twist-lock outlet
  • One 120V three-prong 20 amp twist-lock outlet
  • One 12V DC outlet

The 12V DC outlet comes in handy for charging battery-run appliances such as cell phones, tablets, laptops, audio gear, hard drives, etc.

The twist-lock outlet provides safer and more secure connections between the 8750 generator and plugged in appliances. The twist-lock mechanism makes it very difficult to trip and disconnect the plug.

The 120V outlets, on the other hand, can be used for electronics like refrigerators and vacuum cleaners. Water heaters, air conditioners, ovens, and clothes dryers should be connected to the 240V outlet.

Unfortunately, this generator isn’t RV-ready. You’ll need to buy an adapter if you want to connect the Predator 8750 to your RV or travel trailer.


The Predator 8750 generator has a two-year limited warranty from the manufacturer. It also has EPA (Environmental Protection Agency) and CARB (California Air Resources Board) certifications.

Despite the fact that there are missing features and accessories which other generators offer, the Predator 8750 is worth the investment. If wattage and fuel efficiency are your priorities, then the new Predator 8750 will be the right buy for you.

FAQS on Predator 8750

How Do I Maintain My Generator at Home?

If you don’t use your generator very often, it may get damaged. One way to ensure this doesn’t happen is to run it at regular intervals.

Once a week, run your generator at full capacity. Keep it running for up to 20 minutes at a time. This will heat and circulate the lubricating oil in your engine. While running it for maintenance, check your generator for warning lights, irregular sounds, and leaks.

Do I Need To Get My Generator Serviced?

Your generator produces and supplies energy to all the appliances in your home or work site. It is thus mandatory to have it serviced regularly. By doing so, you can make sure it’s running fine while extending its service life. Skipping maintenance checks can lead to engine trouble, emissions, sparks, and short circuits.

Have generators used for residential or camping purposes serviced at least once a year. More frequent servicing is mandatory for generators used for commercial purposes.

What Generators Are Appropriate for Construction Sites?

Construction sites have slightly different demands when it comes to generators. Below are a few features that you should look for when shopping for construction site generators.

Portability: A construction site entails lots of movement. This holds true for the generators supporting it as well which is why portable generators are the better choice for construction sites. Efficiency: Construction site generators need to run for longer durations without breaks. This calls for a fuel-efficient generator. The less time you spend refueling, the fewer breaks you need. Power: There are different generators based on power capacity. High-powered generators will have a wattage capacity of 200 kW to 2,500 kW. Medium-powered generators are those with wattage capacity between 5 kW to 200 kW. Medium-powered generators are useful for minor projects and repairs. However, a higher kilowatt capacity is necessary for factory and construction work.

Can I Keep My Generator Running All Night?

Yes, if your generator has the fuel and power capacity, then it shouldn’t be a problem. Generally, all generators have at least 8 hours runtime at a reduced load capacity. However, even for generators with longer runtimes, make sure to give them a rest in between. This allows you to run maintenance checks and refuel.

Another safety tip to remember is to never refuel a generator that is running. This advice also extends to generators that are still hot to the touch after operating. If you want to refuel, turn off the generator first and allow the machine to cool down for 15 to 20 minutes. Once cool, you can go ahead and refuel it for the next cycle.

How Much Outdoor Space Do I Need for My Generator?

It differs for all generators so make sure to read the instruction manual. Most generator companies emphasize placing the generator in a ventilated area where the exhaust won’t enter the house.

The main hazards in placing a generator indoors are the risk of fire, short circuit, and carbon monoxide poisoning.

Does A Portable Generator Need To Be Grounded?

Yes. If you have a portable generator, then it needs to be grounded. However, sometimes the frame around the generator can be grounded. Make sure to read your manual for more accurate information on your generator model.

The Verdict: New Predator 8750 a Clear Winner

We hope we answered all your queries and doubts about the old and new models of the Predator 8750. If you’re wondering which one to choose, the new model’s a clear winner. However, the old model is also a great option if you’re looking for a more affordable generator for heavy use.
