The Westinghouse iGen 2500 model comes with a 98cc OHV 4-stroke engine. Predator 2000 comes with a 79cc PREDATOR engine.

Looking at the power output, Westinghouse iGen 2500 manufacturers boast a 2500W starting wattage and a 2200W running wattage. The description is in normal situations, but we want to know how it will perform with home appliances. An air conditioner needs about 1900 watts, an average microwave about 500-1000 watts, and a fridge about 400-500 wattage. So, the Westinghouse iGen 2500 model can power an A.C. alongside a domestic fridge and a very small microwave. Any more than that will be beyond the generator’s capacity.

On the other hand, Predator 2000 has a running 1600W with a starting 2000W. On field testing, the Predator 2000 produced power of up to 1600W before the warning sensors went up. The generator overloaded at 1750W, below the manufacturer’s description.

The fuel capacity is another feature to check out. The Westinghouse iGen 2500 model has around 1.8 gallons. If we look at the fact that the runtime is 18 hours at 25% load, the fuel consumption rate would be around 0.1 Gallons per hour. That’s great. The fuel capacity and consumption rate of Predator 2000 are almost the same as its counterpart. With a runtime of six and a half hours, you can say that it is ultra-gas efficient.

The THD is an important parameter you consider when buying a generator. THD stands for Total Harmonic Distortion. Not to bore you with the concept, the principle is that the lower the THD of a generator, the higher the chances for your electronic appliances to last long. Higher THDs intercept communication transmission lines. The interference can shorten the lifespan of power systems.

Normal generators produce high THDs, which are bad for your laptops, phones, and electric appliances. That’s why people go for inverter generators. The acceptable value of THD is 5%, and inverter generators produce acceptable levels of THD. Westinghouse iGen 2500 and Predator 2000 are inverter generators. So, they have low THDs, making them suitable for your electronic appliances at home.


Noise is what everyone watches out for when buying a generator. The unit of noise is decibels, and everyone wants to buy generators with low decibel values. That’s why people sought-after Inverter generators because of their low noise. Analyzing the noise can be a daunting task. Because different loads give off different decibels, you have to check the noise levels at each level.

The Predator 2000 model produces decibels of up to 64db from 23 feet away. The result is for when you turn on the eco mode. If you turn off the eco mode, the noise goes up to 70db. At 1500W, the noise is at 74db.

Westinghouse iGen 2500 generators are quieter. They produce lower noise levels, around 52db eco mode, and with no load. So, the Westinghouse is winning the comparison of noise.

Although Westinghouse iGen 2500 is quieter, both are quiet enough to take camping or have on during leisure activities.


Westinghouse vs Predator Generators: Which One is Best?

The Westinghouse iGen 4500 has a 224cc OHV 4-stroke engine. The Predator 3500 comes a little below it with a 212cc Predator engine.

According to the manufacturers, the Westinghouse iGen 4500 generator produces peak watts of 4500 with a running watt of 3700. But on field testing, the results reveal different readings. While field testing, the generator did not produce beyond 4100W output. The generator turned off when it got to the 4100W power output mark.

The same is the Predator 3500 generator. The manufacturers boast peak watts of 3500W and a running power output of 3000W, but the field result showed a different reading. The Predator 3500 produces up to 3579W, above its branded power output.

The fuel capacity of Westinghouse iGen 4500 is 3.4 gallons. With a 25% load, the generator could stay for almost 18 hours. This feat gives a fuel consumption rate of 0.19 Gallons per hour. Predator 3500, though, loses out in this fight. With a fuel capacity of 26 gallons, it can last up to 11 hours on a 25% load. So, it has a fuel consumption rate of 0.24 gallons per hour. So, the Predator 3500 consumes more fuel.

Inverter generators have a low total harmonic distortion rate (THD), which makes them compatible with sensitive electronics. Laptops, phones, and LCD televisions are safe with both models due to their low THD. Westinghouse iGen 4500 boasts 0.3% THD, while the Predator  3000 boasts 0.5% THD. These values are within the safe range for sensitive electric appliances. Therefore, you can be sure that your appliances and electronics can last long with those generators.

Noise Comparison

Manufacturers boast 52db for the Westinghouse iGen 3500 generators, but we have our concerns. Under certain conditions, how much noise would the generator produce? At 23ft, on eco mode, and with no load, Westinghouse iGen 4500 produced a noise of 61 decibels. On 750W, the noise was 61.5 decibels. At 1500W, the noise was around 63 decibels. On full load, it produced noise that rose to 74.5 decibels. The Westinghouse iGen 4500 generator was able to pull off such a feat.

In looking at the noise production of the Predator 3000, the equipment performed similarly to how its competition performed. The manufacturer boasts of 57dbA, but field testing shows otherwise. Field testing proved that it produces 62 decibels in normal mode and 63db in eco mode, 23 feet away. If you face the exhaust away from the house, you will get 59 decibels.

So, when it comes to noise, Predator 3000 wins by being quieter than the Westinghouse iGen 4500 model.


Westinghouse vs Predator Generators: Which One is Best?

Right off the bat, you see that Westinghouse iGen 4500 is lighter. The Westinghouse iGen 4500 weighs about 1 pound, while the Predator 3000 weighs around 120 pounds. The amazing thing about the weight is that the Westinghouse iGen 4500 model has a larger dimension than its competitor. Westinghouse iGen 4500 model has dimensions 24.5 x 17.5 x 20 inches. In contrast, Predator 3000 has a dimension of 22.75 x 17.3 x 20 inches.

They both look similar to each other. The Predator 3000, though, has a sturdier and well-arranged design. On the other hand, Westinghouse looks more aesthetically pleasing, but complaints from reviews say that the generators often come with rust.
