Predator 3500 Inverter Generator Review

Concerning its overall appearance, the renowned Predator 3500 (Ebay) Super Quiet inverter generator is similar to the highly praised Honda EU3000Is and even the recent IS1AG and IS1AN upgrades. Even better, when we undertake a rigorous investigation and analyze the engine, the resemblance is profound.

The Predator 3500 inverter generator comes with a higher wattage of 3500 peak power and 3000 watts running power. Still, it uses an engine that essentially has the same power range as the Honda GX200 unit.

The engine of the power equipment Predator 3500 is a clone of the Chinese Honda GX200. And to output more power, the standard displacement has been shifted from 196cc up to 212cc. However, looking at the two engines, mistaking the two is quite easy.

One caveat of improving the engine displacement and not changing the air-cooled cylinder system is that the engine of the Predator 3500 tends to overheat. Increased power with the same design produces more heat, yet the heat transferred from the engine remains similar.

Having gone through countless Predator 3500 inverter generator customer reviews, we’ve noticed that most complaints are to do with the lack of a fuel gauge and engine overheating. However, that doesn’t mean that everybody complains about it.

In other words, the issue may or may not arise depending on how you use the appliance and the overall weather conditions, so if you’re using the Predator 3500 during a hot day. In that case, you can expect to come across overheating problem, particularly when you want a high wattage output for an extensive time. Again, however, it’s not a thing experienced by most people.

The successful solution to the overheating menace of the power equipment Predator generator is to eliminate the insulating panels that cover the generator. Even so, keep in mind that the cover is usually put to make the generator quiet, so doing this will make your generator to be louder.

But on the flip side, it improves the air flowing to the engine, making it run without overheating. Unfortunately, other people have opted to perforate holes through the panels that make for a significant compromise.

The noise level is reduced, and the air flowing to the engine increases, thus improving the cooling property of the engine. If you don’t often use your Predator generators at greater RPM and rarely in hot weather conditions, perforating holes to the enclosure isn’t the best solution. Getting rid of the insulating panels for this case implies that you will not get too loud a generator when you need additional cooling.

Starting The Engine

Aside from the often overheating, Predator 212CC engine works similar to the reputable original Honda. Starting the engine is seamless, whether you’re starting with recoil or an electric start.

You can expect a hassle-free experience with a manual starter, thanks to the wonderful auto-decompression system (Honda-designed). The dial found on the user panel is super-easy to use and comes with 3 positions for a start, run, and off. Further, the engine is both CARB and EPA certified and 50-state legal.

Since the super quiet inverter generator comes with an insulating panel for noise reduction, which is not similar to the metal panels found in Honda EU3000iS, it’s not that quiet. Although, for its overall size with a larger displacement engine, the unit is incredibly quiet. The noise level can go as low as 57 decibels. At this level, the power is about 25% of its capacity or below, and the eco-mode is turned on.

Predator 3500, using Honda technology for its engine, comes with a unique advantage, economization of fuel. Though this is a superior model of the reputable Honda GX200 engine, it doesn’t become thirsty at all.

With a full 2.6-gallon gasoline tank, the 3500 watts super quiet inverter generator can get a good 11 hour run time using 25% capacity. This is a plausible 750W overall load for 11 hours runtime. You might run a 10,000BTU air conditioner when the weather is hot in a day without having to refill the gas tank. Now that is quite impressive.

For example, the warning lighting informs you to overload and low oil. At the same time, the output light indicators tell you that the unit is set for the load. Thus, topping oil is like counting 1,2,3. A side opening of the generator needs no additional tools or complex procedures; as such, you access the oil filler easily.


This generator also isn’t very heavy, particularly for a device with such AC output. It only weighs 110 pounds. Powerful handles located at the back and front of the super quiet inverter generator enable it to be carried by two people in a pretty easy way.

Better still, the built-in wheel kit entails four wheels in every corner. Even that being the case, we must point out that this machine isn’t easy to be moved across rough terrain, but in paved areas, it’s hassle-free.
