Purchase your generator for the best price at Amazon.com!

Yamaha and Honda are two of the most well-known companies in this sector, and we'll compare and contrast them throughout this piece. For those in need of a portable generator as a backup power source or for those shopping for a generator for the first time, then carry on reading. 

You already know that purchasing a generator is a huge investment, so it goes without saying that you should do your research before making your final decision. With so many options available, shopping may be overwhelming.

Therefore, I have put both Yamaha and Honda generators through a battery of tests designed to provide you an authentic comparison of their performance in all respects, from fuel consumption to noise levels.

Let’s compare and contrast the Yamaha generators and the Honda generators.


YAMAHA EF2200iS Inverter Generator, 2200 Watts, Blue

Yamaha has manufactured standby power units since 1973. From there, it went on to develop and release cutting-edge products such the EF2000iS in 2009. The power and portability of this inverter generator is exceptional.

It allowed campers to bring along their microwaves, televisions, and other small equipment in their recreational vehicles.

These generators are excellent due to their high output, low fuel consumption, and low noise levels. Many people who possess recreational vehicles appreciate the versatility of being able to link them together to get more juice out of each. They're great for powering all the gadgets in your RV.

Depending on your needs, a Yamaha generator is a good option for your camper. Whether you need to keep your phone charged or power air conditioners, Yamaha has you covered.

Honda started making portable generators in the 1960s. It was the first manufacturer to create a clean power generator, ensuring the reliable operation of everyday equipment. Clean electricity eliminates any fluctuations in voltage and frequency that could damage sensitive electronics. 

Honda's inverter generators are more convenient than normal generators in every way: they weigh less, are easier to transport, produce less noise, and use less gas.

The "eco-throttle" technology included in its various iterations adjusts the throttle according to user input. This means that the engine doesn't have to run at higher RPMs than necessary during periods of low demand.

This results in less noise and better fuel efficiency from the generators. When you go camping, this is very important.

Yamaha vs Honda

Are you planning on purchasing a high-quality inverter generator to use while RVing, tent camping, or around the house? 

Inverter generators are becoming increasingly popular, but you probably can't pick between the new Yamaha EF2200iS and the Honda EU2200i.

If you're looking for a portable inverter generator, go no further than Yamaha or Honda. Their equipment lasts a long time and works well consistently. 

Let's compare and contrast the Yamaha EF2200iS and the Honda EU2200i.


YAMAHA EF2200iS Inverter Generator, 2200 Watts, Blue

The Yamaha and the Honda are both capable of producing up to 2200W of power and a constant 1800W. With the inverter technology found in each of these generators, you can confidently power delicate electrical devices like computers, cameras, phones, and power tools.

You may obtain nearly twice as much power from two EF2200iS units using the same voltage and frequency thanks to Yamaha's TwinTech Parallel Kit. Two Honda generators connected with the optional pairing connection may also produce up to 4400 watts of power.


Low oil, overload, and operation are all shown by LEDs on both units. The Yamaha features a night light that illuminates the workspace for improved visibility after dark.

You can monitor your power use and gasoline level with its digital load meter and fuel gauge on the Yamaha. Unfortunately, the Honda EU2200i lacks these features.

Fuel shutoff

Yamaha's EF2000IS model differentiates itself with a cutoff valve for the fuel tank. While the device is in operation, the gasoline line can be disconnected. We recommend draining the generator of all fuel before putting it away for the winter.

In this way, the fuel in the carburetor will not go bad. There is no such function in the Honda. After being stored for a while, the Honda could be difficult to start due to the fact that there is just one switch for the on/off and fuel tap.

Volume of Noise

The last thing you need is a noisy generator ruining the ambiance around the campfire or keeping you up at night. The Honda EU2200i has somewhat superior performance than the Yamaha EF2200iS. The EF2200iS generates 57 dB of noise during operation, while the EU2200i generates 48 dB with the same 25% load.

A boost of about 10 dB, or 18.75%, is technically audible. In practice, you might notice a slight variation between the two generators. The numbers don't lie, and neither does the fact that the Honda EU2200i is known to be a more peaceful option.

Fuel consumption

The Yamaha EF2200iS's larger 4.7L fuel tank means it can provide power for longer. Although the Yamaha EF2200iS can run for 10 hours when only running at a quarter of its capacity, the Honda EU2200i, with its smaller gasoline tank, can run for 8 hours when carrying the same weight.

As a result, you'll get around 2 additional hours of power from the Yamaha inverter generator. Neither of the two generators need a lot of fuel to function.

Running efficiency

Computers can adjust the Yamaha engine's RPM in response to the load and save fuel thanks to the Smart Throttle technology and quieter operation. It's also helpful to have a fuel drain. 

The Honda generator also features an economy mode. The "Eco-throttle" system can help you reduce pollution.


Yamaha's EF2200iS retails for roughly $100 less than Honda's EU2200i. Keep in mind that both of these power sources are in high demand and can be tricky to secure at times.

If you plan to purchase one of these generators for your camper, you should definitely get everything set up ahead of time. Your camping trip might have to be canceled since your generator wasn't delivered in time.


Both of these power sources may be relied on, without a doubt. Previously, Honda encountered issues and had to recall over 200,000 units; however, the company has since addressed those issues and made necessary adjustments. Therefore, you can't go wrong with either generating option.

The Yamaha EF2200iS features an easy-to-access, tool-free maintenance panel. Because of this, you can easily get to the heart of the engine and any other parts you might need to replace or repair. To prevent issues with old fuel while storing, just remove the carburetor using a carb drain.

The Honda EU2200i has a few service choices to make routine care as straightforward and trouble-free as possible. The generator's oil level can be monitored with the help of the oil alarm sensor. The engine will shut down to prevent damage, and a flashing light will let you know what to do.

With a wider oil filler aperture, a longer oil spout, and a larger oil drain, Honda made oil changes faster, easier, and cleaner on the EU2200i.

I really like the unique traits that each of these generators possesses. I am a big fan of the Yamaha EF2200iS and its many convenient extras, like its tri-handle, fuel indicator, and 30-amp direct power plug. The tri-handle makes it simple to transport the generator around the campsite and store it after use.

A feature I really like about the Honda EU2200i is the built-in Bluetooth connectivity. The power output of your generator can be managed and tracked wirelessly. Getting up in the middle of the night to go outside and flip the switch is not required.

If you want to hook up your RV to the generator directly, you'll need to get the EU2200i RV kit, which is where you'll find the necessary 30-amp plug.


Both Yamaha and Honda have substantial service and spare parts networks to back up their generous 4-year limited warranties on their generators.

In summary

  1. When comparing engine displacements, the Honda EU2200i's 121cc motor is much larger than the Yamaha EF2200iS's 79cc one.
  2. In terms of power, both the Yamaha EF2200iS and the Honda EU2200i can power the same essential home appliances due to their identical 1,800W of continuous output. Furthermore, since the starting wattage of both generators is the same (2,200 W), the gain in performance of your most power-hungry home appliances will be the same regardless of which generator you select.
  3. The Honda EU2200i has a maximum runtime of 8 hours when loaded to 25% of its maximum capacity, however the Yamaha EF2200iS has a maximum runtime of 10 hours when the tank is full. The Yamaha EF2200iS outlasts the Honda EU2200i by quite a bit in terms of time.
  4. Each generator, when running at the same load level (i.e. 25%), will use about 0.12 gallons of gasoline per hour in terms of fuel efficiency. Among the many available inverter generators, these two are the quietest and most efficient.
  5. The total harmonic distortion (THD) of both the Yamaha EF2200iS and the Honda EU2200i is under 3%, making them ideal for use with your sensitive electronic equipment. Quantifying THDs as a percentage is standard practice.
  6. These two generators produce significantly different levels of noise. The Yamaha EF2200iS is rated for a minimum of 57 dBA, whereas the Honda EU2200i can create noise as low as 48 dBA.
  7. Honda EU2200i's power generation experience is much more compact than Yamaha EF2200iS's, which has dimensions of L21.9 inches, W11.8 inches, and H18.5 inches.
  8. Comparing the EU2200i to the EF2200iS, which weighs 55.2 pounds, the EU2200i is noticeably lighter at 47.4 pounds.
  9. The Yamaha EF2200iS's triple handle makes it easier to carry than the Honda EU2200i's single handle, making the former more portable.
  10. These two machines can be started with the tried and true method of pulling the starter cord.
  11. Outlets, the Yamaha EF2200iS is better than the Honda EU2200i in this category because it provides three AC outlets, while the latter only provides two. There are no ground fault circuit interrupter (GFCI) outlets in either. However, the Yamaha does go a step further by also providing a DC output. Keeping in mind that their combined output voltage is only 120V is crucial. Each outlet has its own product page on their websites. 
  12. The data centers built into each of these portable generators make it feasible to track a wide range of useful information on the generated electricity. In addition, a fuel gauge is included. The Yamaha EF2200iS also features a fuel gauge that displays the exact amount of gas in the tank at any given time.
  13. A system that checks the level of carbon monoxide (CO) in the air is a great plus point to them both. The Honda EU2200i also simplifies things by letting you access key data via the My Generator app on your smartphone. This will drastically simplify your daily routine.
