Searching for the right product can be a tiresome process, especially when it comes to generators. Most people don’t have the industry-specific knowledge to tell these models apart. That’s why we’ve eliminated your work by compiling all the information you need right in one place.

Here’s what you need to know about Yamaha’s popular generator.

What is an Inverter Generator?

First, let’s make sure that we are all on the same page. The Yamaha EF2200iS is an inverter generator, which can electronically change the engine’s output to meet demand. It will not run at full force if it is not necessary. Getting engine speeds to match demand makes the generator more fuel-efficient and environmentally friendly than other types of generators.

This type of generator is highly sought after and is perfect for either recreational or commercial use.

Yamaha EF2200iS Specifications

The particular model we are discussing today exhibits the following specifications:

  • 2200 watt maximum output
  • 55.2 pound dry weight
  • 21.9 x 11.8 x 18.5 in dimensions
  • 1.24-gallon fuel tank capacity
  • 3-year limited warranty

Features and Functions of the Yamaha EF2200iS Inverter Generator

Now let’s talk about some of the features and functions of the Yamaha EF2200iS that make it stand out from its competition.

Yamaha MZ80 79CC Engine

The powerful high output Yamaha MZ80 produces unmatched power. At a 1/4 rated load, the engine can operate for 10.5 hours. This run time is quite impressive and beats out many other inverter generators on the market today. If you need many hours of power, the EF2200iS should top your shortlist of potential generator choices.

Yamaha Quiet Technology

Thanks to this generator’s Yamaha Quiet Technology, you could hang out near one and may not even realize it is running. The generator produces noise that is just about as loud as a normal conversation. This decibel level makes it remarkably easy to tune out and have fun going about your business without being distracted by the generator’s annoying engine running.

Tri-Handle Design

The new design makes moving around the EF2200iS a breeze. The handles are placed specifically so that two people can move the generator easily. Whether you are moving around the campsite or the yard, getting this generator from point A to point B will be no problem for you.

The unit only weighs fifty-five pounds, which is a weight that most people can handle on their own. If you have the help of a partner, you will have absolutely no trouble at all.

RV Outlet and DC Socket Outlet

This model is designed with an RV camper in mind. Gone are the days when you spend hours at the hardware store trying to find the right adapter. Now the RV outlet is a plug that comes standard on the generator, so you will be good to go right from the start. Incorporating a standard RV outlet on the EF2200iS is a major perk for RV lovers.

In addition to the RV outlet, you will also find a DC socket outlet allowing you to plug in even more devices directly to the generator with ease. With this regulated DC socket outlet, you will easily charge all the devices you need, which can be a godsend when you are out camping or if your home loses power in a storm. This socket location, right in the control panel, makes it especially easy to find and use.

Twin Tech Parallel Function

The EF2200iS features a tech parallel function, allowing its users to get even more power than a single inverter generator can provide. What this feature does is that it lets people connect two EF2200iS units easily.

Just be aware that the Twin Tech parallel cable is sold separately. However, once you acquire this one cable, you will be all set to hook it up and use the convenient twin tech parallel function to get two EF2200iS units together.

Yamaha Smart Dial

The smart dial knob allows you to start and stop your generator quite easily. The Yamaha smart dial long run time will completely change the way you operate your generator. You will not always have to rely on the manual recoil start.

LED Illuminated Control Panel

The new led illuminated control display will tell you everything you need to know about your generator, even in low-light situations. The illuminated control panel makes working your generator easier than ever before.

Smart Throttle

EF2200iS features Smart Throttle, a load sensing control for RPM that allows for less noise. By automatically adjusting engine speeds, this is an RPM control that allows greater fuel efficiency as well. Amazing fuel efficiency and noise reduction are two things that many people look for in inverter generators.

Yamaha Easy Carburetor Drain

The Yamaha easy carb drain is one of the simplest yet most useful features of the generator. It is a carburetor drain that allows you to remove the fuel easily.

A process that used to be cumbersome can now be completed with the simple turn of a knob. This simple action can save you so much trouble and make sure that your generator is ready for long-term storage.

Fuel Gauge

The easy-to-read fuel gauge allows fuel level to be seen with just a glance, instead of doing any complicated measuring. The unit fuel gauge allows you to see exactly how much fuel you have left so that you know precisely how much more power you have before you need to refill.

Pulse Width Modulation (PWM)

Featuring pulse width modulation, the inverter generator makes power that is remarkably clean and efficient.

The high power output featuring pulse width changes sets this generator apart from its competition.

Overload Reset Button

The EF2200iS has a useful feature in the overload power reset, enabling users to restore power without turning off the entire machine. In the event of a power overload, all you need to do is hold this button down for three seconds, and the device will get the power working again right away. Now you can restore power without shutting everything off.

Frequently Asked Questions

Now, let’s go over a few things that you might be wondering about the Yamaha Ef2200iS and inverter generators in general.

Are Yamaha Generators any good?

This is a fundamental question, but it is honestly worth asking. The short answer is yes. While Yamaha might be more well-known for some of their other electronic products, their generators are no joke. The quality you have come to expect from Yamaha musical instruments can be found in the inverter generator as well.

How Does the Yamaha EF2200iS Compare to the Honda EU2200i?

Now you might be wondering exactly how the Yamaha Ef2200iS stacks up to the Honda EU2200i. Both generators give off the same amount of power at 2200 watts, are well-suited for use with RVs, parallel with other generators, and are extremely fuel-efficient.The Honda EU2200i is a bit lighter, has a more comprehensive warranty, and is a little quieter than the Yamaha EF2200iS. However, the Yamaha has its tri-handle design, illuminated multi-function LED display, larger fuel tank capacity (1 and a quarter gallon), a longer run time on a 1/4 rated load, and a tool-free maintenance panel.

The Honda EU2200i also comes with Bluetooth and Honda My Generator app capabilities, the CO-MINDER carbon monoxide detection system, and enhanced ventilation. However, we cannot forget that the Yamaha EF2200iS offers a smart dial knob, overload reset button, and the ability to tell the fuel level easily.

While these models have their differences, fundamentally, they can serve all the same purposes.

What’s Better: Honda or Yamaha Generator?

Now that you know how these two models differ, you are probably wondering which brand is better. The answer is that it depends. You must first evaluate your priorities to discover the things that you find most valuable in an inverter generator.For instance, if you are interested in an inverter generator with an exceptional warranty and especially quiet performance, then the Honda EU2200i will be the best best for you. Whereas, if you want a generator that is especially powerful and is simple to operate and maintain, then the Yamaha EF2200iS is the pick for you.

You have to understand that there is a give and take. The Yamaha is heavier because it has a bigger, more powerful engine. You give up a bit of portability for more power. It would be best if you about the qualities that would be the most important to you. If ease of movement is your most important feature, you might choose the lighter option even though the other will provide you with a slightly longer run time.

There is no right answer for everyone. With these companies producing high-quality generators, you must look at the details to differentiate one from the other. Depending on what you prefer, what you are using the generator for, and your budget, you may find the Yamaha more appealing than the Honda or vice versa.

Luckily, you really cannot go wrong, whether you go with the Yamaha or the Honda.

Are Yamaha Generators Quiet?

woman signals silenceIn short, Yamaha generators are quiet, but they are not the quietest option on the market.

The quiet operation of Yamaha generators is one of their biggest perks. If you are looking for generators that produce a noise level that can easily fade into the background, then Yamaha offers quite a few options that will excite you.

However, if you are looking for the quietest possible option, you should know that the Honda EU2200i is slightly quieter than the Yamaha EF2200iS. The Yamaha operates at 57 – 65 dBA while the Honda runs at 48 – 57 dBA.

The louder operation of the Yamaha can easily be attributed to its larger and more powerful engine.

Although both models would certainly be considered quiet, if absolute quiet is a must-have for you, you may want to consider the Honda EU2200i.

Verdict: Should You Buy the Yamaha EF2200iS?

With the EF2200iS’s sophisticated, quiet technology, rich features, and unmatched high power output, few inverter generators stand up to it. While the Honda EU2200i is a worthy adversary, the Yamaha EF2200iS has some perks that make it an exceptional choice.

You will not be disappointed if you choose to purchase the EF2200iS.

Consider purchasing the Yamaha EF2200iS to transform your RV camping experience or merely have it on hand in case of an emergency at home. No matter what you want to use your Yamaha EF2200iS for, it will be up to the challenge.
