Predator 3500 Inverter Generator Review


When it comes to generators, it is the power of a generator that catches the interest of any potential buyers and users of the device. 

Measured in Watts, knowing the power of a generator will also give you a better understanding of what it is capable of powering and running. Therefore allowing you to understand whether it can supply you with the power that you need.

As the name suggests, the Predator 3500 has a maximum output power of around 3500 watts, and the running power of the generator is around 3000 watts. 

This relatively small difference of 500 Watts shows that this generator maintains a steady flow of power. This is quite a rarity among most generators.

It is important not to surge the power of the generator to its maximum level too long; manufacturers would advise running the generator just below its surge level.  

What Can Predator 3500 Inverter Generator Run? 

With a top line of 3500 Watts, the Predator 3500 is a powerful generator within its own right. 

As we’ve stated above, this model of the generator is more than capable of maintaining that power level, meaning it is a perfect generator for powering a range of different devices.

This generator is capable of powering a number of different devices all at once, making it ideal for use in an RV or on camping trips. 

The power capabilities also make it an ideal choice as a whole house generator at home. 

With 3500 watts to use, the predator can easily run kitchen appliances such as microwaves, kettles, and refrigerators in the event of an emergency or blackout.

The digital display onboard the Predator generator 3500 will also enable users to monitor the power being supplied by the generator. 

This will allow users to understand when too much power is being sent to any other devices.

Fuel Efficiency

The Predator 3500 inverter is famed across the industry for its fuel efficiency and running time. 

With a fuel tank holding around 2.6 gallons, the generator can run for 11 hours at 25% load, better than many devices in its categories. 

The only one downside when it comes to the fuel section of the generator is the fact it does not have a fuel gauge. 

However, you will soon get used to not having this fuel gauge as there is an hours counter that will alert you based on time instead.

To prevent any problems, the Predator 3500 also comes with a low fuel shut off that kicks in when the fuel becomes too low.

Pros & Cons


  • Low-level noise.
  • Small purchase and running costs.
  • Low maintenance is needed.
  • Lightweight and easy to move.


  • No fuel gauge.

Portability, Size & Weight

The Predator’s portability is another of the shining qualities that make it popular with other predator inverter generator review pages. 

Weighing in at just over 99lbs, its maneuverability is quite surprising given its size and much lighter than its competitors in this division of generators.

Although light in its field, you yourself may be intimidated by the weight of the Predator 3500. 

Equipped with both a set of wheels and a number of carrying handles, there’s nothing to worry about. 

Having these wheels makes the mobility of the generator a breeze, another reason why this is seen as a truly universal piece of kit.

Along with the weight of the generator, its dimensions also add to its appealing mobility and maneuverability. 

The size of its width and length makes it easy to store in the trunk of most cars and even at home in the smallest of places.  

Noise Level

At 57 dB, the Predator 3500 is surprisingly quiet compared to the power it is capable of producing. 

This lack of noise makes it a great choice for using on RV sites or camping sites and at home when using it to power tools. 

The Predator 3500’s extra-low noise output is one of the generator’s best features and is seen as one of the reasons so many people opt for this design.  

Predator 3500 Generator Oil

The Predator 3500 generator generally uses 10W-30 engine oil, and it is this that many recommend using throughout the Predator generator range of models.

If you are planning on using the generator only in the warmer months and storing it in warmer environments, then 10W-30 engine oil alone is fine.

If the oil will be in the engine during winter and you live in a place where it gets cold during these months, use 5w30 oil instead.

Changing the oil on a Predator 3500 is also a lot easier thanks to the rubber flap that runs along the bottom of the device and pulls away with ease. 

The control panel has a helpful panel that alerts users to the low level of oil. There is also an inbuilt feature that will automatically gout off the generator if the oil level becomes too low.

This will stop the generator from seizing and damaging itself through a lack of lubrication.    


The Predator 3500 comes new with a manufacturer warranty of 2 years. 

This means that you are covered for 24 months after the date of purchase.

Making any changes to your generator, whether that be fundamental changes or cosmetic ones, can affect your warranty validity. 

As this is the case, it is far better to take the generator to a Predator technician than attempt any repairs yourself, especially if you are unsure of what you are doing.

One of the best things about the Predator 3500 warranty is the 90-day replacement feature. 

If for whatever reason, there is a fault in the design or the workings of the generator in the first 90 days of purchase, it will be replaced by a brand new product. 


The Predator 3500 produces some of the cleanest power compared to its competitors and is considered the best when it comes to emissions. 

This model of generator is both EPA-approved and CARB-compliant making it available for sale in all 50 states of the US, a feat that would be impossible for most fossil-fuel fueled generators.

This is mentioned a few times but not so much it has become a huge issue with users and reviewers.

Concluding on all that we have seen and reviewed about the Predator 3500, it is clear to see it is a device perfect for mobile use.
