Yamaha EF2200iS Review – how does the Newest Yamaha Inverter Generator perform?

Yamaha has for a long time been one of the leaders on the market of portable inverter generators. Their most popular inverter generator – EF2000i and its second version – EF2000iSv2 (which I reviewed in details here) quickly became the most sought after inverters along with the Honda generators.

EF2220iS is the newest inverter generator released by Yamaha. What can you expect from this generator? Is it better than its predecessors? We’re going to have a closer look at it in the following article

Yamaha EF2200is – My First Impressions

Yamaha pays a lot of attention not only to the quality but also the looks of their products.

EF2200i is no exception. It has a very handy intuitive design which in my opinion looks much better than its direct competitor – Honda EU2200i.

The generator features a illuminated multi-function LED display. It makes operating this machine much easier, especially at nightime.


It features a dedicated RV outlet – great news for RV owners since you don’t need to bother with purchasing an additional adapter.

This generator has a got a larger engine and it’s, therefore, a bit heavier to carry around than its older cousin. Fortunately, it has three strong handles which make it easier for two people to carry it together.

I also really like the Overload Reset Button. It allows you to quickly restart the unit at a single push of a button without having to manually shut it off and on.

Yamaha EF2220i vs EF2000iSv2 – how are these two different?

The first and most important difference is that EF2200i has got slightly higher wattage. 

It has the maximum AC surge wattage of 2200 and running wattage of 1800, as opposed to 2000W / 1600W offered by EF2000iS. 

While not a huge difference, it might still be a game changer for those who want to squeeze every single watt of power from their inverter generator.

This unit has received a brand new design to fit the more powerful engine.

One of the features I really love the most and missed something like this a lot in the previous versions is the so-called “Smart Dial Knob”.

It basically allows you to start and stop the generator without having to resort purely to the manual recoil start.

As I’ve mentioned before, Yamaha EF2220iS is a bit heavier than its predecessors due to its larger engine. However, it still weights than less 60 lbs. This makes it possible for two people (or one strong person) to carry it on the campsite.

Some people using the EF2000iS and EF2000iSv2 complained about fuel related problems, usually resulting from the dry fuel getting stuck in the carburetor.

This has been fixed in this model with the introduction of the Yamaha Easy Carb Drain System. It allows you to quickly get rid of the remaining fuel from the carburetor at a simple turn of a knob. I would recommend performing this simple task every time you want to store your generator unused for long periods of time.

EF2200iS has got a brand new Yamaha MZ80 79cc engine. Engines are what Yamaha makes best and this one does not disappoint either.

Is it as quiet as older models?

Inverter generators manufactured by Yamaha are renown for their quiet operation.

That’s why they became so popular with campers and RV enthusiasts. 

We’ve actually found EF2000iSv2 to be one of the least noisy inverter generators money can buy. (you can read more about our recommendations for inverter generators here)

Regrettably, EF2200iS is a bit louder.

It produces around 57-60 dB at 25% load. Why I certainly wouldn’t say this is loud, it is still a few decibels more than EF2000iSv2.

This can be easily attributed to the larger and more powerful engine – a perfectly understandable thing. 

On the other hand, Honda EU2200i offers the same power output and runs a bit quieter than Yamaha EF2200iS.

At the time of writing, I do not recommend Honda EU2200i though. Read below why.

Yamaha EF2200iS vs Honda EU2200i – how do they compare (hint: EU2200i has been recalled, don’t buy it now)

I have previously compared Yamaha EF2000iSv2 to Honda EU2200i. One obvious difference was that Honda’s generator offered more running wattage.

Now when Yamaha released EF2220iS which offers the exact same power output as EU2200i it made even more sense to rank these to against each other.

Unfortunately, back in March 2019, American Honda had to recall 200,000 generators including EU2200i because of a potential fire hazard resulting from a manufacturing defect. At the time of writing this article (late May 2019), Honda still has not officially confirmed whether the issue has already been resolved. (source: cspc.gov)

So, while its main competitor has still not “recovered”,  at this moment Yamaha EF2200i can be potentially described as the best 2200 watt inverter generator.

One thing I wished it did better though is its noise level. No matter what the load is, Honda EU2200i is simply quieter than EF2200i. 

The Carburetor Drain is a great feature helping prevent problems with dried fuel

Are there any downsides?

As with other Yamaha inverter generators, I would say that the only thing which gives me a pause is the price.

Yamaha is fully aware of how strong their brand is and prices its products accordingly. 

At a time of writing (22 May 2019), I found Amazon to be one of the trusted sellers which sell it for the best price. But no matter where you buy it, be ready to spend at least $900 for this generator.

On top of that, it is a brand new model and it is unclear yet how those units are gonna perform after a few months of intensive usage during the summer months. 

On the other hand, since Yamaha is a very trusted brand, I am optimistic that Yamaha EF2200iS will not disappoint.

EF2200iS is overall a very promising generator

Final Verdict – Should You Get It?

This is a very new model and time will show how well it performs in longer term. 

The initial opinions about this generator are very positive with customers reporting it to be well fitting for RV, capable of powering an air conditioner, microwaves etc.

My impressions of this inverter are very good too. I think Yamaha made a great decision to release such generator to fill the market gap after Honda EU2200i’s recall. 

If I were you, I would be happy to give it a go, providing that your budget allows.

8.2 Total Score
Yamaha EF2200iS - a very promising inverter generator

This newly released generator has got the potential to win the title of the best inverter generator in the near future. Yamaha is a very trusted brand and you can't really go wrong with any of their products, including this one.
