Comparison With the Similar Inverter Generator

Now, let’s compare with a similar inverter generator in this range.

Probably, Honda is the most popular inverter generator. But unfortunately, Honda doesn’t have an inverter generator with such power wattage. You will get the 4500-watt generator from the Honda which is not an inverter generator. That is an economical series generator.

However, for your convenience, I have counted the Honda EU3000IS. This one comes with 3000-watt power. Yes, it is super like, but this generator’s price is way higher than the Westinghouse igen4500.

Let’s compare it with another popular inverter generator that comes with 4500-watt power. I Briggs & Stratton P4500 is almost similar to the Westinghouse igen4500.

The main drawback of this Briggs & Stratton P4500 is the noise level. It produces 61-decibel noise. On the other hand, the Westinghouse igen4500 has only 52 decibels.

Compared with the price, Briggs & Stratton comes with the lowest price tag. If you have a budget problem and sacrifice the noise issue, you could consider the Briggs & Stratton P4500.
