Construction and Design

Predator 3500 Watt Generator Design

The strong ABS plastic of the exterior is even better than other Predator generators. Besides, you will have your fuel tank cap surrounded by a spill tray, which is backed by rubber. The cap is threaded and has a filter to separate the debris.

Now, many customers claim that this inverter does not have a fuel gauge. Despite that this is true, the generator does have a fill level indicator inside the tank. However, it is important to keep in mind that this is not nearly as effective as a gauge.

Both sides of the machine have metal handles. Moreover, you can pull or push this machine on four rubber backed smooth wheels which are also lockable. However, some units of the generator might rattle a bit.

The inside of the generator is deeply insulated. On the other hand, the battery is larger than the average size and is also protected in the lower right corner of the generator. Underneath the battery, there is an anti-vibration silicone pad that provides a rock-solid grip on the main structure.

Additionally, there is a large muffler along with a spark arrestor on the rear of the product. The right-hand side of the inverter houses the pull handle that sits on a metal housing.

Engine and Power

Generator Engine

Compared to other inverter generators, the Predator 3500 has a much more powerful engine. Actually, it has a 4-stroke 6 horsepower OHV engine. This is the reason why you can get more power out of it. The engine displacement is measured to about 212cc. A bigger engine displacement gives better efficiency.

Both electric and recoil start options are available for you. When you start the engine, you will have a surge wattage of 3500 and a continuous wattage of 3000. The maximum output will be 25 amps.

You will be shocked to see the rubber anti-vibration motor mounting set. There are four of the rubber seals to keep the engine smooth and stable.


Fuel Gallon

Gasoline is the primary and only fuel for this generator. Therefore, there is no dual-fuel capability. Try to use non-ethanol gas. However, manufacturers claim that a 10% ethanol would not be a problem.

Besides, you do not have the burden to mix different oils with this engine. The maximum capacity of the fuel tank is 2.6 gallons. With a full tank, you will have an 11-hour runtime on 25% load.

Receptacle Panel Configuration

Predator 3500 Watt Generator Control Panel

First, let’s talk about AC outlets. There are two 120 volt AC outlets (each of them with safety breakers). The RV adapter that comes with the generator goes into a 120-volt twist-lock AC outlet.

On the right-hand side, you will have the start dial and start button. Along with that, there will be the eco-throttle button. You will also have a two-pin DC outlet with a breaker. It is a 12-volt outlet with a maximum capacity of 8 amps. The parallel outlets will be covered with rubber sockets.

An LCD screen on the panel shows all kinds of information like amps, voltage, wattage, etc. The safety indicators are also placed under the screen.


This feature allows you to run the generator at lower RPMs, reducing noise. Furthermore, it also plays its part in protecting the environment by reducing fuel consumption.


Inverter generators are supposed to be quiet. But this generator takes that to another level. Measured from 23 feet (7 meters), it is just 57 decibels. You will notice the difference immediately when you fire up the machine.

This model is certified by both EPA and CARB. Yes, you can get it in the golden state. However, the generator is still subject to proposition 65.

Some Small Drawbacks of the Inverter

Although the unit has no significant problems, we have located some minor issues that you should know about. Here are the things that Predator still needs to improve –

Small and Rattling Wheels

Despite being very smooth, the wheels tend to rattle. Furthermore, the wheels are also smaller compared to the total size of the machine.

No Fuel Gauge

The machine is missing a fuel gauge, which is a standard feature for this range of generators.

There is no need for a fuel gauge as the runtime is always updated on the display panel. Nevertheless, we had to disclose the lack.
