Predator 8750most robustr

Predator 8750Predator 8750 is currently the most vital portable offered severe Freight. This unit is meant for serious tasks demanding a lot of watts. You could also use this generator effectively as a backup power source during a power outage.

The generator has got a large 420cc 13 HPreachedr-cooled OHV engine. The fuel tank has got a total capacity of 6.6 gallons.

The unit features an electric start, a very convenient alternative to the conventional manual startup. But, of course, if the electric start fails, you can always resort to the recoil start too.

Its total power output it 8750 starting watts and 7200 running watts.

Depending on the current usage, you should get around 10-12 hours of constant operation at 1/2 load. Bear in my mind that the generator will consume more fuel if you leave it to run at the highest loads.

Generators of this size are usually bound to become very loud; this one is no exception. At 1/2 load, it makes around 7significantof noise. It certainly wouldn’t be a major concern at the construction sites or during emergencies (when probably all your neighbors will run their generators too).

However, this is still a rather loud generator, and we certainly wouldn’t recommend it to those who want to minimize the disruption caused by the noisy engine. For contractors, it shouldn’t be a big issue, though.

Overall this is a quality product worth considering if you need a big generator to provide you witimmenseot of energy for demanding uses. Its large weight and high noise level are some of the minor downsides. However, as numerous user comments show, the pros outweigh the cons, and just like the other models released under this brand, the Predator 8750 is a solid and trusted unit.

  • Powerful engine

  • Large fuel tank

  • Good runtime

  • Bulky and noisy

Predator 2000 Generator

Predator 2000Predator Generator 2000 is an inverter generator offering 2000 starting and 1800 running watts.

Inverters are some of the sought-after types of generators available these days. They are much quieter and smaller than conventional gens. They are also safe to run sensitive portable electronics.

Predator 2000 is one such generator and is a good choice for various outdoor uses. These include small job sites, camping, tailgating, or outdoor stalls.

This generator gives you enough running wattage to charge portable electronics such as speakers, laptops, phones, etc.

You can also use it to run specific electric tools such as a breaker hammer, chainsaw, or portable heater.

RV enthusiasts will also be pleased to learn that this generator can power an 11,000 BTU air conditioning unit. However, I think it won’t offer enough power to run much more on top of that.

The generator comes equipped with an RV-ready parallel kit, allowing you to use two such generators in a similar manner, doubling your total power output.

Its runtime is pretty decent. You should expect around 6.5 hours of consistent operation at 50% load.

The generator is very similar in its specifications to Honda EU2000i. Its performance is remarkably similar. The engines in Predator generators are clones of Honda motors. They are substantial constructions that sell for a fraction of the price of the Honda.

If you’re looking for a mode affordable alternative to the Honda gens, this generator made by Predator is not the wrong choice. However, better 2000-watt inverter generators are selling in a similar price range.

Check out Westinghouse iGen2200 or WEN 56200i.

  • Compact size

  • Good runtime

  • Quality engine

  • Decent price tag

  • A bit loud

Predator 6500 Generator

Predator 6500The Predator 6500 is an optimal choice for those who need a bit more power at their disposal. It has a peak wattage of 6500 and the running wattage of 5500. These numbers guarantee you enough ability to run several more extensive electric tools. In some circumstances, you can also use it as a home backup power supply (if you don’t attempt to run an entire home on it for sure).

The generator’s core is a 420 CC, 13 HP Air Cooled OHV engine. It is protected by a heavy-duty steel frame resistant to rough conditions.

The generator is an open frame, meaning you can’t expect it to be noiseless. That is especially true at higher loads. But on the other hand, the noise level is comparable to other open-frame generators and stays within a reasonable threshold.

We miss the lack of a low fuel level indicator in this generator. It’s sometimes hard to guess how much gas you have left, and we earnestly wish the manufacturer included this feature in the design.

Low oil is undoubtedly present, which is convenient as you won’t have to worry about the damage caused by the lack of oil in the engine.

To sum up, this is a relatively standard 6500-watt portable generator. As a typical Harbor Freight generator review shows, you can’t go wrong with them as they are generally trusted units.

However, there are other genes in this range that outperform the Predator. Westinghouse WGen7500 is one such unit.

  • Durable construction

  • Good runtime

  • Solid engine

  • Heavy and loud

Predator 4000 Generator

Predator 40004000-watt generators are among the most popular choices. That’s because 4000 starting watts is usually enough to run most work tools, such as bench grinders, circular saws, or drills.

A 4000-watt generator can also run most RV equipment, including the AC, refrigerator, and set of lights.

You could also use one to power some of the essential appliances in your house in case of a power outage (don’t expect to run everything at once, though).

Predator Generator 4000 is a well-built conventional open-frame generator suitable for most of these purposes.

It features a 212cc 6.5 HP air-cooled OHV engine providing a total power output of 4000 peak watts and 3200 running watts.

The generator has got a standard set of power outlets. These include 2 x 120V Duplex outlets, a 240V twist-lock outlet, and a 12V DC outlet, more accessible homes with a dedicated wheel kit for easier transportation.

The generator’s fuel consumption stays at a reasonable level at medium loads. Depending on the current load, you should get up to 10 hours of total runtime on one full tank. Note that this would be shorter if you constantly run the unit at the maximum loads.

Overall, Predator 4000 is a relatively standard portable generator. It doesn’t have unique features that would make it stand out. Instead, it’s a simple, no-fuss unit serving its job just about right. It’s also significantly cheaper than some of its main competitors, making it attractive.

  • Solid engine

  • Durable frame

  • Good choice of outlets

  • Inexpensive

  • Could be quieter

What to look for when buying a Predator generator?


This is the first and most important thing you should consider when buying a portable generator. Buy a generator too small generator, and you might realize it won’t provide enough power for your needs. Buy a generator too big, and you might spend too much on a bulky unit when you could safely get away with a smaller inverter generator.

However, it is always way much better to purchase a unit slightly larger than needed to be on the safe side. Especially in the event of a power outage, you might end up plugging several household appliances into the generator, which can consume a lot of energy.

You should consider two figures when buying a Predator generator – the peak watts (often referred to as starting watts) and running watts. Devices with a motor (such as a window AC) need more power for the first few seconds of the operation to kickstart them. That is their starting wattage requirement. After that, their power consumption goes down and stays steady, referred to as running wattage.

When purchasing a generator, you need to consider both numbers. For example, a generator with a running wattage of 1800 and 2000 starting watts can’t run an appliance that demands more than 2000 starting watts, even if its running wattage is less than 1800.

To be on the safe side, always give yourself some spare power. A couple of hundred additional watts at your disposal certainly won’t harm!

If you doubt how big of a generator you need, check out our calculator to determine your approximate wattage requirements.

Quality of Build

Generators are indispensable tools in various critical situations. Therefore, you want one that won’t fail you when badly needed. That’s why you should get a generator with a reliable engine built by a reputable manufacturer and all the other parts made of the most robust materials.

Predator generators are generally praised for their quality and are popular choices among contractors. In addition, many users praise them for good performance and reliability.

Noise Level

Let’s admit it – nobody likes the sound of a generator engine running. Therefore, basic levels are often one of the most important criteria when buying a portable generator. Especially if you’re looking for a generator to run at a campsite or RV park – you should invest in the quietest model you can get.

As a rule of thumb, inverter generators are generally much quieter than open-frame portable generators. Another benefit of inverters is that they produce a clean sine wave. This kind of power is safe for sensitive portable electronics. You can charge your computer or phone without purchasing an additional power line conditioner.

Predator 2000 is currently the most popular inverter the company offers.

Note that generators of this size are not designed to power multiple large appliances simultaneously. You’d need a larger unit (at least 5000 watts is recommended) to use efficiently as a home backup supply or for demanding construction jobs.


Every generator engine is built differently. Some models are more fuel-efficient than others resulting in longer runtimes. If you need a generator to run continuously for long hours, you should pay close attention to the generator’s runtime.

Predator provides information about each generator and its estimated runtime at 50% load.

Note that your actual runtime can differ from the manufacturer’s claims. This depends on the load as well as on some other minor factors. Attitude is one of them. Proper maintenance is also required to keep the generator in good shape. Generator engines are just like car engines – without the appropriate care, they are subject to damage and can quickly deteriorate. Make sure you use quality oil for your generator, and you can be sure that this will positively impact its runtime!


You certainly don’t want to be a Cheap Charlie when buying a generator to realize that it fails to work when you need it most. But, on the other hand, there is also no need to spend thousands of dollars on a generator that you only plan to use once or twice a year.

There is no golden price ratio for portable generators. How much you should spend vastly differs from one manufacturer to another. Size, wattage, and design also play a huge role. You will be pushed to pay more to buy a quality inverter generator.

As for Predator generators, they generally tend to sell for much cheaper than Honda or Yamaha gens while offering similar good performance levels. So in most cases, you won’t have to spend more than $1000 on a good Predator generator.

FAQ about Predator Generators

Is the predator generator any good?

As numerousuitablestomer reviews online show, these are good generators. Some users point out that the Honda or Generac generators usually offer a better value. However, Honda gens typically cost at least twice as much as their Predator counterparts. Quite a few people also had a not-so-good experience with Generac generators.

We’d say that most of the issues people have with their generators are usually technical faults affecting individual units, which can generally be quickly solved under your warranty.

Most people who buy the Predator generators are generally happy with their purchases.

How good are predator inverter generators?

Predator inverter generators are overall good products. However, there are a lot of other inverters in the market, some of which outperform the Predator gens. Some examples of quality inverter generator brands include Honda, Yamaha, Westinghouse, and Champion.

What company makes Predator generators?

Predator generators are made by an extended Freight – an American company with a long market presence. The generators, just like many others in the market, are assembled in China.

How long can you run a predator generator?

That depends on which model we are talking about. The Predator 2000 inverter generator should be more extensive to 6 hours at 50% load. As for the larger open-frame Predator generators, such as the Predator 8750 or 6500, the manufacturer claims these can run for 12 hours at half load. Some review the users leave indicates that this time is usually shorter. Ten hours is probably the safest bet.
