What will the Westinghouse iGen4500 run?

It is easy to see in reviews that the Westinghouse iGen4500 offers 4500 peak watts, 3700 running watts, 120 volts, and 30 amps.

However, you likely also want to know what this means in terms of the appliances and tools the Westinghouse iGen4500 can actually run.

From a high level view, you can say that this generator can run a nice amount of small to medium devices together or somewhat bigger machines separately.

As an example, a Westinghouse iGen4500 should be able to run a coffee maker, refrigerator, dishwasher, electric drill, and laptop at the same time.

Some of the bigger machines the Westinghouse iGen4500 should be able to run individually are a window air conditioner (15,000 BTU), a table saw, or a 1 HP air compressor.

Westinghouse iGen4500 customer reviews insights

Just because a generator looks good on paper does not always mean the brand delivers on its promises.

To make sure there are not too many unexpected problems with the Westinghouse iGen4500, the reviews of the thousands of customers before you can be helpful.

While I did not read every single review, I did find some general trends when digging through a lot of them.

First of all, there are a decent number of reviews that mention changing the oil can be challenging due to the design of the Westinghouse iGen4500.

There also used to be an issue where the iGen4500 choke wire was not always connected but it looks like Westinghouse has resolved this issue (and it should be a relatively easy fix in case it does happen).

A tiny number of customer reviews mention the occasional technical issue or that the generator is not as quiet as they hoped.

These things do need to be noted but at the same time, there are not that many generators that are able to keep this many customers as happy as the Westinghouse iGen4500.

Westinghouse iGen4500 alternatives

As you can see from this review and the top pick spot in the best 4500 watt generators, the Westinghouse iGen4500 is one of the best overall options out there.

At the same time, it is worth briefly mentioning two alternatives.

First, the Champion 200988 4500 DF seems to be just a bit more reliable than the Westinghouse iGen4500 but does require a bigger investment.

If you really have essential appliances, you could consider the Champion 200988 4500 DF for backup power.

Secondly, the WEN 56455i looks like a solid 4500 watt inverter generator at a more budget-friendly price than the Westinghouse iGen4500 but does not have that many customers yet.

Is the Westinghouse iGen4500 worth it?

While you do want to check whether you need this much power, the Westinghouse iGen4500 is likely worth it if you are looking for 4500 starting watts.

Even if you only focus on specific categories, it is often hard to find other generators that do a better job than the Westinghouse iGen4500 (although there are examples).

At the same time, this generator still has a very reasonable price.

In short, when it comes to 4500 watt generators, the Westinghouse iGen4500 is basically the best option out there.
