Predator Company Background

Predator Generators are popular with many and are created by a company called Harbour Freight Tools. Harbour Freight Tools is a retailer that sells discounted equipment and tools. They have their own lines of equipment and tools that include the Predator Generators. 

Their tools are typically sold at a lower price because they are created by the brand and are not bought from other manufacturers. They are not lower in quality, however. 

Harbour Freight Tools was founded in 1977 and was originally a family-owned business. Over the last forty years, they have grown in popularity and strength. They are best known for their discounted products and lower prices.

We have divided our review of the Predator 3500 Inverter Generator into useful specification sections for you to easily find all of the information you need. 


The Predator 3500 has a simple design. It is mainly black with red sides. It is a reasonably sized generator that is portable and safe to use outdoors. Given it can be used outdoors it is fairly durable.

Its specific dimensions are 22.75 x 17.3 x 20 inches. Although it is a larger generator. It can still be stored if needed. The Predator weighs a total of 110 pounds. This is fairly light for a mid-size generator. However, it still may be heavy for some users.

As it is not the lightest generator to carry, it does have four wheels built into its chassis. The wheels, although small, are durable and can travel across different terrains.

The majority of portable generators only have two wheels at the back to pull the generator along. Having four wheels makes moving the generator easier. You do not have to tip it backward on two wheels.

In addition to the wheels, there are two carry handles on the top of each side of the generator. This is great as it allows two people to carry it with ease.

t also allows you to pull the generator along. However, the Predator 3500 would benefit from having a pull up handle.

Given that it is not the lightest generator to transport, it would make this process a lot easier as the other handles are fairly low down. 

Cost And Warranty

In terms of cost, the Predator 3500 is of great value for the money given that it is a mid-size generator. It is a good competitor to similar generators on the market.

It has an overall warranty of two years. In comparison to some other generators of this size and this price range, this is fairly short.

However, within the first 90 days of purchase there is a replacement guarantee should anything go wrong with the Predator.


The total power of the Predator’s engine is 3500 watts. The running watts is 3,000 and the surge watts is 3,500.

There is very little difference between the two which is great as it is easier for you to know what power capabilities this generator has. 

The engine that runs the Predator is a 212cc gas engine. It is air-cooled which stops the engine and other important components from overheating and damaging.

The overall tank size is 2.6 gallons. In comparison to similar brands, this is fairly average. 

In comparison to its competitors, on the whole, it is one of the more powerful generators available.

If you are looking to power multiple things at once, or things that require a significant amount of power, this would be a great option for you.

If you want more power, you can connect two of these generators by using a parallel kit. By doing this you double the power to 7000 watts, which is substantial.

By doing so you will be able to power more tools and even provide enough electricity to power things such as refrigerators and freezers for a short period. 

It also has electronic overload protection for added safety when in use. The engine has an eco mode to help you save energy, and this mode is better for the environment overall.

Run Time

The run time of the Predator is particularly good.

At a quarter capacity, it can run for 11 hours. If you need power throughout the night, this is great. 

As it is fuel-efficient, this allows the engine to run for longer too.

Noise Levels

Considering this is a mid-size generator, its noise levels are particularly good.

It is one of the quieter generators on the market. If you are planning to use it while camping, RVing, or at night, this is a great advantage as it will not keep you or your neighbors awake.

When it is working at its maximum capacity it will only reach 57 decibels of sound.

Ease Of Use

Overall this is a fairly easy generator to operate. It has an LCD screen that displays information.

It also has a low oil indicator which will notify you when you will need to add oil to the engine. This will help to protect your generator’s engine.

In addition to this, there are overload and output light indicators. These are all displayed on one side of the generator on a control panel.

Power Outlets

The Predator 3500 has three separate power outlets. There are two 120V grounded outlets, and one 12V DC outlet.

This outlet allows you to charge a car battery which is useful if you are using this generator while away from home.

For safety, their power outlets do have a circuit breaker just in case anything goes wrong with them.
