Power Comparison

The Generac GP2200i model comes with an 80cc Generac OHV engine. Westinghouse iGen2200 comes with an 80cc 4-Stroke OHV engine.

Considering the power output, the Generac GP2200i model has a running voltage of 1700w with a starting voltage of 2200w. If two GP2200i models are connected, it will power the RV air conditioner, phone chargers, as well as lights. It will also power up portable appliances.

On the other hand, in Westinghouse iGen2200, manufacturers can boast a 2200w starting wattage and a 1800w running voltage. This description is normal, but let’s look at home appliances’ performance. A fridge will need about 400-500 wattage, and an average microwave will need about 500-1000 wattage. Hence, the Westinghouse iGen2200 model can power a small microwave and a domestic fridge together. An air conditioner needs about 1900 watts, which will be beyond the generator’s capacity.

Another feature to check out is the fuel capacity. The Generac GP2200i has a fuel consumption rate of 0.11 gallons per hour. This is around 1.2 gallons and runs for about 5 hours of continuous use at 25% load. The Westinghouse iGen2200 model has fuel efficiency, which can last up to 12 hours of usage time without any problem. It also has a 25% capacity, the same as the Generac GP2200i model.

THD, which means total harmonic distortion, is very useful when considering the type of generator to buy. A lower THD generator is the best choice for your electrical appliance to last long. Higher THDs interfere with communication transmission lines. This interference can reduce the lifespan of power systems. These generators produce fewer emissions.

Generators producing higher THDs are not the best for your electrical appliance, laptop, and cell phones. Inverter generators produce lower THDs, and many people prefer to buy them. The acceptable THD value is 5%, and inverter generators produce acceptable levels of THD. Generac GP2200i model and Westinghouse iGen2200 are inverter generators. These generators have a low THD indicator of less than 3%. Hence, they are low, which is suitable for your home appliances.

Noise Comparison

Noise is not pleasant to the ears and should be considered when buying a generator. Noise is measured in decibels, and buying a generator with a low decibel value should be your choice. Inverter generators are bought because of their low- noise. If you do not like the noise of conventional generators, you should consider getting an inverter generator.

Generac GP2200i falls between 60 and 70 decibels, reducing noise levels, and making it neighbor-friendly and quiet. Westinghouse iGen2200 generators are extremely quiet; it has a reduced noise output of 52 decibels. This low decibel value is great for house use and can also be used for barbeque in the yard.

These inverter generators can increase or decrease the throttle. This helps to match the power requirement instead of operating full-time. Although Westinghouse iGen2200 is quiet compared to Generac GP2200i, both can be used for leisure activities during camp.
