Aesthetics

From the get-go, the Honda EU2200i is a reddish box-like generator. It has small dimensions and is smooth to the touch, making it something someone would love to carry around in his R.V. or have in the backyard.  The Cumming’s Onan P2500i has a greyish color. It is box-like also and has a nice feel to it. It is compact, and the LED display makes it look cool.

If we use appearance to judge, our pick would be the Onan P2500i. Now, we understand that beauty is in the eyes of the beholder. Red is an attractive color for people, enough to make them buy the Honda EU 2200i. If you are one of them, that’s great. Grey may be bland for some, but it works as a camouflage in the woods and doesn’t stand out too much. That makes it a desirable option also. Whatever brand you pick, we assure you that it’s a great choice.

Pricing

The Onan P2500i model also wins in terms of budget-wise price. It costs around $820. The downside is that it is very rare. It is hard to find the brand in some areas, but it’s worth the price when you do. The Honda EU2200i is expensive. It costs $1,195 as a starting price on Amazon. The good news is that it is a popular brand. So, you find them at any tech store or on Amazon.

Sometimes, Onan P2500i may not be out of stock on Amazon, and it won’t be nice if you’re in an emergency. Honda EU 2200i, on the other hand, is very popular. So, you will always have it in the store anywhere you go. So, it remains a viable alternative.

But in case you are desperate for a cheap alternative, general generators are a choice to consider. If you’re interested, we made an article that compares the Generac vs. Honda generators. Generac generators may be the alternative you have in mind.

Performance

Honda EU 2200i has a powerful 121cc Honda GXR 120 engine compared to the Onan P2500i 98cc OHV 4-stroke engine. The Honda model easily wins the competition in this round.

It is normal to ask if the Honda EU 2200i will be louder with its powerful engine. The Honda EU 2200i exceeds our expectations by being as quiet as the Onan P4500i. The Honda EU 22000i is 57db in eco mode. With no eco mode, it’s 62db with no load at all. When we load the generator to the fullest, it produces a noise level of about 72db. That’s very impressive.

In contrast, Onan P2500i operates at about 60Hz. Not to bore you with the maths, that frequency produces about 69.5 dB of noise. This is impressive, but you can’t compare it to the 57db that the Honda EU 2200i produces. Let’s conclude that E.U. 2200i means the sound check by a mile.

The strength of the Onan P2500i performance is in its running and starting wattage. It boasts an impressive 2200 running watts and 2500 peak watts. Compared to its competitor, the Honda EU 2200i generator is a little bit behind. It has a peak watts of 2200W and a running 1800W. The good thing about the Honda EU 2200i model is that it is very consistent with its claims. It runs well at full capacity. So, you can always be safe when you use it at full capacity.

Based on fuel consumption, Onan P2500i also wins by running for 10 hours on a 25% load. The Honda EU2200i runs for 8.1 hours on a 25% load.

They all have their quirks in regard to features. You can always check out the guidelines to see their advantages. We like the app feature on the Honda EU 2200i. It connects to your generator by Bluetooth. It helps you monitor the generator’s oil levels and load output. You are also able to turn off the generator from the app. Unfortunately, it doesn’t show fuel levels, and the generator doesn’t have a fuel gauge.

The Honda also has a C.O. sensor system. It detects Carbon Monoxide and turns it off after 25 seconds. It also alerts your app through a pop-up on your phone. The CO sensor feature makes the Honda EU 2200i very safe.

The LED display of the Onan P2500i is a major plus to its features. It displays fuel level, power output percentage, run time, and lifetime run hours. It also has two USB ports for USB- compatible devices.

Both models have the parallel capacity, so you can double your power using another of its kind.

Verdict

The manufacturers made the Honda EU 2200i generator to be portable, but the Onan P2500i possesses more performance. Honda is a popular brand and is trusted around the world. Honda is a good brand to look for if you’re in a rush. It is also very portable and helpful for camping and RVing. If you’re looking for overall performance, the Onan P2500i is a great choice.

With the foundations set from the first model comparison. You should know what we should be looking for in a review. We would briefly comment on the various aspects of the Honda EU 3000is and the Onan p4500i and give you our verdict.

Aesthetics

The grayish color and control panel make the Onan P4500i generator look super cool. The most common color of the Honda EU 3000is brand is red. Red can be attractive, but it stands out.

Pricing

Performance

The Onan P4500i is the winner of the sound test comparison. It’s a hard decision to make due to the difference in engine capacity, but our bias is that we are looking for quieter generators. Honda produces 57dbA at 800 watts load. At full capacity, it is 71.5db. The 57dbA is quiet enough for a conversation, but the Onan P4500i has a lower noise level. The manufacturers boast a noise level of about 52dbA.

Their power output of them is very interesting. Onan P4500i takes an overwhelming lead with an 1100 difference in running power and a 1500 difference in peak power. Honda EU 3000i has a fuel consumption rate of 19.6 hours, and the Onan P4500i boasts 18 hours on a 25% load. So, Honda wins this round. Also, they both have less than 5% THD, making them for sensitive devices like your laptop and phone.
