Some of the main differences between the Cummins ONAN P2500i and Honda EU2200i are that the Cummins has more power, a longer run time, better fuel efficiency, a built-in LED screen, and a more budget-friendly price.

On the other side, the Honda EU2200i has lower noise levels, the My Honda Generator App to track and stop remotely, a CO-minder, and customer reviews that are a lot more positive.

Because the Cummins ONAN P2500i has a good amount of technical issues, you will likely prefer the Honda EU2200i in this comparison.

However, you do want to know that there is also the Westinghouse iGen2500.

This generator is basically the more budget-friendly and higher-quality version of the Cummins ONAN P2500i.

In turn, you may prefer the Westinghouse iGen2500 over the Honda EU2200i if you don’t mind a bit less reliability and durability.

Differences Cummins ONAN P2500i vs Honda EU2200i explained

The table of main differences and a quick look at the prices and customer reviews are often enough to choose between the Cummins ONAN P2500i and Honda EU2200i.

That being said, your decision could also become easier with the more in-depth explanations of some of the differences.

User reviews Cummins ONAN P2500i vs Honda EU2200i

When I compare generators I typically look at feature differences first.

However, the customer feedback about the Cummins ONAN P2500i and Honda EU2200i is so different that this area deserves a mention first.

More specifically, the Cummins ONAN P2500i reviews are overall not that positive with how relatively often customers have technical issues.

Even to the extent that this can interfere with camping trips or tailgating parties. Let alone home backup power of important devices.

The Honda EU2200i also has a few very exceptional cases of technical issues but this is still one of the most reliable and well-received generators on the market.

Fuel efficiency

All portable generators work with the fundamental principle of converting fuel into electricity but as the Cummins ONAN P2500i and Honda EU2200i show, they can do this at different rates.

With the running watts, run times, and fuel tank sizes, you can make an estimation of how many kWH (energy measurement quantity) each generator gets out of a gallon of fuel at 25% load.

These calculations imply the Cummins ONAN P2500i gets 5.500 kWH out of a gallon of fuel whereas the Honda EU2200i “only” gets 3.837 kWH out of the same amount.

One of the more straightforward consequences of this is that the Cummins ONAN P2500i offers you slightly more budget-friendly power.

However, you also don’t want to forget that getting more gasoline can just be really inconvenient in certain situations and locations.

In short, basically everyone will prefer the Cummins ONAN P2500i over the Honda EU2200i in terms of fuel efficiency.

Winner: Cummins ONAN P2500i

Generator performance tracking

There is a difference in performance tracking between the Cummins ONAN P2500i and Honda EU2200i but the first thing to note is that this will likely not influence your decision too much.

The main reason I’m mentioning this detail is that something like the Honda My Generator App is not that common and well-known.

In short, this is an app that allows you to connect your smartphone to the Honda EU2200i.

With it, you can track details like output power, oil life, run time estimations, etc. You can even stop your Honda EU2200i from a distance.

The Cummins ONAN P2500i also offers many tracking details like wattages, run time remaining, and lifetime run hours.

However, you need to walk up to the generator to see these measurements.

Other generator features will likely be more important to you but it is fair to say that it is generally a bit more convenient to track Honda EU2200i performance.

Winner: Honda EU2200i

Price

You do want a generator that fulfills your needs for a long time to come but at some point, price will likely influence your choice too.

Any big differences in this area could also help if you are still deciding whether the Cummins ONAN P2500i or Honda EU2200i is right for you.

This can be different when you read this but at the time of writing, the Cummins ONAN P2500i is a good amount more budget-friendly than the Honda EU2200i.

Winner: Cummins ONAN P2500i

Is the Cummins ONAN P2500i or Honda EU2200i right for you?

In short, the Cummins ONAN P2500i has a higher power capacity, a longer run time, better fuel efficiency, a built-in LED screen, and a price that is a good amount lower.

On the other hand, the Honda EU2200i is quieter and has the My Honda Generator App to track and stop remotely, a CO-minder, and customer reviews that are a lot more positive.

With the number of technical issues the Cummins ONAN P2500i has, many people will just prefer the Honda EU2200i.

However, it is important that the Westinghouse iGen2500 exists.

This is basically the higher-quality and more budget-friendly version of the Cummins ONAN P2500i.

In turn, the Westinghouse is a good Honda EU2200i alternative if you don’t need as much reliability and durability.
