Choosing between the Westinghouse iGen4500 and Champion 4500 can be challenging because they are so similar.

The main differences between the Westinghouse iGen4500 and Champion 4500 are that the Champion 4500 is just a bit more fuel efficient and has a 12VDC outlet.

On the other side, the Westinghouse iGen4500 has a bit more running power, a longer run time, a lower sound level, and a slightly longer commercial warranty.

If you really want to fuel efficiency and a 12 VDC outlet, you could consider the Champion 4500.

That being said, most people will prefer the extra power, longer run time, and lower noise level of the Westinghouse iGen4500.

You do want to know that the differences between these generators are not that big either.

Any temporary good deals could make the Westinghouse iGen4500 or Champion 4500 the better choice anyway.

Differences Westinghouse iGen4500 vs Champion 4500 explained more in depth

If you are somewhat familiar with generators you are likely able to choose between the Westinghouse iGen4500 and Champion 4500 with the table of differences and a quick look at their current prices.

That being said, it is also possible that you are not completely sure about what certain differences exactly mean and/or how they should influence your decision.

You can find some of the most confusing differences between the Westinghouse iGen4500 and Champion 4500 explained more in-depth below.

Run time and fuel capacity

Generators convert fuel, in the case of the Westinghouse iGen4500 and Champion 4500 gasoline, into usable electric power.

Due to differences in fuel capacity and fuel efficiency, different models can vary a lot in terms of how long they can run on a fuel tank.

More precisely, the Westinghouse iGen4500 can run about 18 hours at 25% load on its 3.4-gallon fuel tank.

On the other side, the Champion 4500 runs around 14 hours at 25% load on its 2.3-gallon fuel tank.

So the Westinghouse iGen4500 does perform a nice amount better than the Champion 4500 in these areas.

This is definitely welcome but at the same time, having to refuel your generator just a bit more frequently is often not the end of the world either.

You will likely still prefer the Westinghouse iGen4500 in these areas but it is still possible that the Champion 4500 deserves a chance if it performs better in other important areas.

Winner: Westinghouse iGen4500

Fuel efficiency

While generator brands typically don’t mention any form of fuel efficiency, I do like to mention this estimated detail since it is still relevant to some extent.

There are different ways to approach this but I like putting the fuel efficiency of generators into how much kWh (power) they can generate with 1 gallon of fuel.

From the mentioned run time and fuel tank capacity, the Westinghouse iGen4500 offers about 4.897 kWh per gallon of fuel.

On the other hand, the Champion 4500 does a bit better by offering around 5.326 kWh per gallon of fuel.

In simpler words, the Champion 4500 is able to convert one gallon of gasoline into just a bit more power.

This is slightly more helpful in terms of budget, how much fuel you have to take along, and environmental concerns.

Winner: Champion 4500

Outlets

After you get to generating the power you need, you still need to be able to connect your electrical devices to these power sources.

The Westinghouse iGen4500 and Champion 4500 are very similar in terms of outlets but the small difference is worth quickly noting.

Before going into this, both of these generators have a duplex of 120V 20A 5-20R outlets and a 120V 30A (TT-30R) outlet.

Then when it comes to differences, the Westinghouse iGen4500 comes with two built-in USB ports.

The Champion 4500 instead has a 12VDC outlet and comes with a dual port USB adapter in case you still want these too.

In simpler words, the 12VDC outlet of the Champion 4500 makes it just a bit easier to connect to certain devices.

Whether this extra outlet is actually a benefit and to what extent depends on what devices you want to power with your generator.

Winner: Champion 4500

Price

By now it is likely clear that the Westinghouse iGen4500 and Champion 4500 are very similar in many ways.

In cases like this, price differences can sometimes be the deciding factor.

That being said, even in this area, the Westinghouse iGen4500 and Champion 4500 are often similar.

I use the word often because temporary deals can easily swing this part of the comparison either way.
Winner: Similar but sometimes there are deals for the Westinghouse iGen4500 and Champion 4500

User reviews Westinghouse iGen4500 vs Champion 4500

One more area you can check before actually making your decision is the experiences of the hundreds of customers before you.

Checking out the reviews of the Westinghouse iGen4500 and Champion 4500 can be helpful because there are sometimes downsides to generators that are not really highlighted on the list of features.

That being said, the overall reviews of the Westinghouse iGen4500 and Champion 4500 are typically very positive.

In the case of the Westinghouse iGen 4500, there are a few individuals who find changing the oil harder than it should be due to the design of the generator.

On the other side, there are a few exceptional cases where customers experience technical difficulties with the Champion 4500.

Overall, customers are just a bit more positive about the Champion 4500 but at the same time, the nature of the exceptional suboptimal reviews could make you more interested in the Westinghouse iGen 4500.

Is the Westinghouse iGen4500 or Champion 4500 right for you?

In short, the Westinghouse iGen4500 has just a bit more running power, a run time that is a nice amount longer, a lower sound volume, and a slightly longer commercial warranty.

On the other hand, the Champion 4500 seems to offer just a bit more power per gallon and has a 12VDC outlet.

When it comes to investment requirements, these generators are typically similar but temporary deals can make a nice difference.

Individuals who want the 12VDC outlet and/or want to stay as fuel efficient as possible may prefer the Champion 4500.

That being said, most people will prefer the Westinghouse iGen4500 because it makes less noise, offers a bit more power, and requires fewer refuel sessions.

It is worth noting that all of these differences are relatively small. If you encounter any good deals, this could influence your decision.
