But don’t lose sight of two of the most crucial portable power factors – affordability and ease of use. To choose the best generator for your RV or household you should consider all the factors. Then, match them to your personal needs. Weight, size, noise, available ports, and voltage are only some of the considerations.

Choosing a clear winner between the Cummins Onan P2500i and the Honda EU2200i was tricky. Each brings unique features and capabilities to the table. These two power-generating inverter gens were neck-and-neck in most of the comparison categories.

The Honda EU2200i has a few more great tech features but needs to justify the price difference. So I give the podium spot to the Cummins Onan P2500i. It produces a little more power and is a much more affordable price.

I also compared these two competitors in various other categories. For example, I looked for a winner in power output, engine size, runtime, start method, and some others. Your preferences, requirements, and views may differ from mine. You should pick your winner based on your own needs and requirements.

So, you may be new to the RV family or want to replace or augment your current electricity supply. In that case, we will answer all your questions.

Cummins Onan P2500i vs Honda EU2200i: Comparison Table / Statistics

Overall, there is not too much difference between these two generators. They’re not chalk and cheese. Both have several similarities, with only a few differences. So, our winner is the P2500i. This is because it is cheaper while still performing well on most entries in the comparison table.

Cummins Onan P2500i

The P2500i does lack a few ‘nice-to-have’ features compared to the Honda. But if you do not require those specific features, its price will make your wallet happy.

Honda EU2200i

The Honda ticked a few more tech-y boxes but was also more expensive. So, if you are prepared to pay the price, the EU2200i should be your choice.

WINNER: HONDA

Cummins Onan P2500i vs Honda EU2200i: Weight, Portability & Wheel Kit

Both these generators are portable, and weight and portability are always important. However, there is almost no difference between our pair, so we declare a tie in this comparison.

Cummins Onan P2500i

You can take this power source anywhere when weighing in at 48 lbs. dry weight.

Honda EU2200i

With a 47 lbs. weight, it is amongst the best lightweights in the generator market.

WINNER: TIE

Cummins Onan P2500i vs Honda EU2200i – Power And Engine

It’s all about the engine and power. After all, the primary purpose of any generator is to deliver electrical power. The P2500i takes the honors for two reasons. First, it generates a little more energy. And second, it is less prescriptive with its parallel capability.

Cummins Onan P2500i

It does deliver more wattage. And you can connect it in parallel with another P2500i, 4500i, or p4500iDF generator. It also comes with an economy mode switch for when you’re not needing quite so much power.

Honda EU2200i

Produces little less wattage and can only pair with EU2000i or EU2200i models. Its Eco throttle feature will also adjust the engine speed according to the power demand.

WINNER: CUMMINS

Cummins Onan P2500i vs Honda EU2200i -Runtime

Runtime and economy work together. Again, very few differences between these two, and both are economical and will supply you with almost one day’s power on a gallon. However, the P2500i had its nose slightly ahead across the finish line and took the win.

Cummins Onan P2500i

Because this generator produces more wattage, it runs for about ten hours at a quarter load.

Honda EU2200i

The EU2200i will give you about eight hours of power. However, its fuel tank is smaller, and the electrical power supply will also be slightly less at a quarter load.

WINNER: CUMMINS

Cummins Onan P2500i vs Honda EU2200iStart Method

It is a pity that neither has an automatic start, as both use the recoil starting mechanism. But the Honda is the winner in this category. This is because it has an advanced starting system. You can also monitor and stop the generator remotely.

Cummins Onan P2500i

The P2500i uses the standard recoil starting system.

Honda EU2200i

The EU2200i has an automatic mechanical decompressor system. This reduces the force required to start the generator and makes life much easier. Although it has a manual start-up, there is an app that allows for remote stopping and monitoring.

WINNER: HONDA

Cummins Onan P2500i vs Honda EU2200iFeature Comparison

This is where the Honda EU2200i nudges ahead toward the finish line. It has a few additional useful features that will put a smile on the faces of many RV owners.

Cummins Onan P2500i

The P2500i is a solid generator. It has all the basic features the average camper or homeowner would need from a small generator. It ticks most boxes except for a few technology-driven nice-to-haves. But what it does have is an overload circuit breaker, automatic low oil shutdown, and an economy mode switch.

Last, although it is not a technology feature, it has a convenient top rubber mat. That gives you somewhere to put your devices during charging.

Honda EU2200i

First, the EU2200i comes with an Eco-Throttle feature. It manages the engine speed according to the power draw. This reduces fuel consumption, noise, and exhaust emissions.

The ‘My Generator’ smartphone app allows you to monitor or shut down the generator from a distance. So you can use Bluetooth on your phone as a remote for your generator. This is unquestionably a lovely touch.

The ‘Co-Minder’ feature monitors Carbon Monoxide (CO) levels. And at the first sign of noxious emissions, it will shut down the generator, keeping you safe.

It also has a ‘Fuel Off’ switch position. This allows the engine to run until most of the fuel in the carburetor is consumed before shutting down. So another weight off your mind.

Last, the ‘Protected by Oil’ Alert will shut the generator off when the oil level is too low. It also has AC and DC circuit protection switches.

WINNER: HONDA

Cummins Onan P2500i vs Honda EU2200iControl Panel and Ports

We struggled for a winner in this category as the two contenders are playing in the same league. While the P2500i has a LED display and USB ports, the EU2200i has smartphone monitoring. So I decided this category is another tie.

Cummins Onan P2500i

The P2500i comes with two 5V USB ports. These are ideal for charging your sensitive electronics, like tablets and phones. It also has one 120V 20A AC outlet and a 12V 8A outlet. The control panel has a LED digital display. It gives accurate readings for the remaining runtime, power output, fuel, and voltage. This makes a difference as it removes the guesswork from running a generator.

Honda EU2200i

The EU2200i has a 20A 125V Duplex AC receptacle and a DC output port. This is for 12-Volt automotive batteries. The control panel has three alert indicators, AC circuit protector, and Eco-Throttle switches. But it lacks an electronic display. This is OK, because you can manage features from your cellphone screen. Having said that, it lets itself down a little by not having any USB ports for your devices.

WINNER: TIE

Cummins Onan P2500i vs Honda EU2200i Fuel Efficiency

Like the runtime category, fuel efficiency is essential. You want your electricity generation to be as cheap as possible. Especially with the fuel market as it is. Both these generators are very fuel efficient. But again, it is the P2500i that walks away with the first position.

Cummins Onan P2500i

The Cummins P2500i produces more wattage and runs for longer at a quarter load.

Honda EU2200i

The EU2200i is blowing in its rival’s neck. It produces similar results. It achieves these with a slightly lower power output and shorter runtime.

WINNER: CUMMINS

Cummins Onan P2500i vs Honda EU2200i – Noise

The noise that your generator makes is critical, especially when outdoor camping. However, both these contenders have super low noise levels. Still, the Honda EU2200i edged it with lower decibels while operating at quarter load capacity.

Cummins Onan P2500i

The 52 dBA is more than acceptable. It is lower than many rival generators.

Honda EU2200i

The 48 dBA wins. It does so because its eco-throttle manages the engine speed. This means overall reduced noise levels.

WINNER: HONDA

Cummins Onan P2500i vs Honda EU2200i – Warranty

Again, an almost tie with both manufacturers providing a 3-year residential warranty. I decided to give Honda the pole position. It has a brand advantage and a reputation for quality products and excellent after-sales services.
