Best Features of Predator Generators

Predator is a trustworthy brand that has consistently demonstrated its dependability through its best features.


The company utilizes engines from Briggs & Stratton, which are famous for being reliable and effective for domestic and commercial use. The similar Honda engines found in Predator generators, which have a range of 2000 W to 11,000 W with single-use, are relatively well known.

These portable generators are reasonably quiet, with a noise level between 56 and 70 dB. Additionally, the majority of their generators have EPA III and CARB certifications.

Best Value For Money

The company charges less for its generators than other brands. The cost ranges from about $350 to $800, with an average price of $500. The units’ moderate weights are comparable to those of other brands, and it rises with the engine’s weight and capacity.

You may get a fantastic price with a predator generator that is reliable, fuel-efficient, and produces a lot of power output. You will also find an electric start, low oil and shutdown indicator, and many power outlets in most models.


Even though their reliable engines lack the dual-fuel capability, a conversion kit makes it simple to add it. In general, units are simple to install, operate, and find replacement components. Customers like the brand because of its large selection of silent and portable generators. Predator generator reviews can easily persuade one that the brand produces top-notch portable generators.

You could decide to get a Predator generator after seeing their incredible performance. However, finding the one that satisfies all your requirements takes time and effort. You must research the various models, their features, and their specifications.

Are Predator Engines Any Good?

Heck yeah! Ok, so here’s the thing. After doing some research, I learned that Predator engines are pretty much a duplicate (or clone as they call it) of the Honda generators. This means a couple of things;

First, that they are super reliable. Second, that parts are interchangeable. So if you happen to have an old Honda generator engine around, you can use parts to fix your Predator engine (I mean, if you’re really into that kind of thing). And last, it’s backed by a great business – Harbor Freight.

Is Predator a Good Brand?

Besides personal experience, I’ve done a lot of digging on this brand of generators and they are solid. One of the reasons this brand is trustworthy, as mentioned above, is that they’re actually manufactured and distributed by the same company – Harbor Freight.

How Long Does A Predator Generator Last?

The large fuel tank for most Predator generator models holds 2.6 gallons. That much fuel is enough for the 212cc engine. Its high fuel economy is a result of this combination. You conserve energy while still having access to sufficient power to enjoy your camping location. One tank should easily last 11 hours with a 25% load setting. Therefore, you won’t need to refill at night.

When operating at 50% load, you should receive 6 to 9 hours of running time. Your gas consumption will depend on how much gear you have at the moment. You would need to recalculate if you needed more power at any point throughout those 11 hours because it would require more gasoline.

One of the reasons these generators are so well-liked is their outstanding performance. You do not need to go out late at night and get more fuel. The good news is that Harbor Freight also offers extended runtime gasoline kits to prolong run times further.

How Long Can a Predator Generator Run?

How long can the predator generator run

The amount of power you wish to generate and the running time are equal. The generator will run for longer if less energy is required. The Predator 3500, for instance, has an 11-hour runtime rating at 25% load.

So, how good are Predator generators? The device will operate for approximately 9 hours at 50% load. The large fuel tank that Predator built enables these running times. This type is so fuel-efficient that running it all day will take up to three gallons of gas.

It can produce 3500 watts at startup and 3000 running watts while operating. That ought to be more than sufficient to power your RV’s equipment. The loudness and weight, both on the high half of the scale, will be the significant problems. Overall, you should be able to run your generator for the few hours you want to power it. It is best to limit the number of appliances you use at once.

What Is The Warranty On A Predator Engine?

Many people are concerned about warranty coverage. One benefit of Harbor Freight is that they sell many affordable tools and products exclusively sold under their brands. The warranty will function as an exchange if you can bring the device into the store. A direct-exchange warranty could be a welcome change for many customers who are sick of dealing with third-party manufacturers and their varying turnaround times.

Harbor Freight provides a 2-year warranty on the engines’ emissions control systems for Predator goods, including pumps, pressure washers, and generators. The standard 90-day guarantee is valid for all machines. The 90-day warranty will also apply to any Predator accessories you buy.

Do Predator Generators Come With Oil?

You would be mistaken to believe that the 20-ounce oil reservoir provides you with a free oil tank. There is oil in the tank, but there is a good reason for it to be there.

Before packaging the generator, the corporation drains the oil added to the tank and checks all its products before shipment. Since the company didn’t remove all of the oil before shipping it to you, some of it may still be in the tank or engine.

You do not get to bypass the breaking-in period for a generator just because the corporation runs tests before you obtain it. It is best to thoroughly fill the generator with the required fluids and run it for a predetermined period to lubricate every crevice inside the engine.

You should be able to utilize the generator generally without any problems after that interval in time. The breaking-in period helps avoid dry starts, which is why most generators are damaged.

What Kind of Oil Does the Predator Engine Use?

What kind of oil does the predator engine use

According to Predator, you should fill your Predator generator with synthetic oil, especially a synthetic combination of 10W-30. Other types of oil are also acceptable, but you should keep essential things in mind.

If it is 32° F (0° Celsius) or above outside, Predator 212 engines require 10W-30 oil. According to the manufacturer’s handout, 5W-30 oil will also be better appropriate if the outside temperature is below 32° F. Consequently, 10W-30 engine oil would be suitable for most situations.

Do not combine pure synthetic and synthetic mixture motor oils. This combination won’t damage your Predator Generator, but it can make it less effective.

You can increase the lifespan of your appliance and achieve the most outstanding results by checking the oil levels before each usage.

Can Predator Generator Get Wet?

It is not advisable to use this product in wet conditions or when wet, even though it has safety features. This caution applies even if your hands are damp. Because you are working with electricity, someone could electrocute you with this device’s power.

It is essential to check that all of the generator’s parts are dry before connecting the power connections. Additionally, moisture might cause short circuits and harm the generator’s internal components if you store it in an area unprotected from humidity.

Having a tent or cover over it is good to ensure that your Predator generator always stays dry. Rain and snow will cause issues with even the most robust generators.

Although the Predator 3500 modes may appear to be waterproof, there are enough gaps and fractures in the construction to allow water to enter the device undetected. To avoid problems, always avoid caution regarding electrical power equipment and dampness.

Do Predator Generators Need To Be Grounded?

Yes, grounding a portable generator is necessary! A grounding rod inserted into the surrounding soil should be connected to the metal frame of the generator using a single cable about the size of a battery jumper cable. The RV will be grounded back to this through the plug ground when plugged in.

Although all RVs now feature Ground Fault Receptacles, it will prevent any stray current from inflicting an electrical shock. An additional layer of protection is offered by driving into a ground rod.

Before use, you must correctly ground the Predator generator in compliance with all applicable electrical laws and standards. If you are not a qualified electrician, have the unit grounded instead by a professional.
