Are Yamaha Generators Any Good?

Yes! One of the greatest portable generators is the Yamaha EF5500DE since it gives your necessary appliances dependable and efficient electricity. Even while the excess surge power is smaller than that of most generators, with a working period of 9 hrs, it consumes fuel very effectively while simultaneously providing clean electricity.

You can benefit significantly from large portable generators during challenging situations. In times of need, such as hurricanes, they supply enough electricity to run the essential appliances at home. These are also common for building sites when multiple heavy tools are utilized simultaneously.

One drawback to the majority of them is their high price. But despite high prices, these generators are unique. It is one of the most reasonably priced ultra-duty portable generators available.
An integrated 59cc 4-stroke motor powers the generator. It has an output of 12000 beginning watts and 9500 operating watts.

You could practically use it as a portable backup generator for your entire home, given the amount of power at your leisure. This is because you do not try to manage every aspect of your house simultaneously. However, it would be ideal for situations requiring an emergency.

The machine features a capacious 7.0-gallon gasoline tank. For further security, it is encased in a sturdy steel frame. The usual outlets are available, which you may use to power different electrical equipment and appliances.

It’s a camouflage design.  This generator is incredibly portable with large suitcase-style handles and light weight of only 46 lbs when fully fueled. So if you want to go fishing or hunting, it is not only lightweight and portable but also small and easily stored in your car’s trunk or the rear of your SUV.

Easy to use

It has various self-protective features that, in addition to making it easy to use, safeguard the engine from damage and human mistake and make maintenance simple. For instance, removing the side panel should not need a wrench or screw, which is one of my favorite features.

Easy to use

Based on the lifespan they give the owner of a Yamaha generator, the specific characteristics I will discuss, in my humble view, make it worthwhile to spend the money. Remember that the most important thing is to enjoy your leisure time with relatives and the environment rather than Reviewing and maintaining your generator. Your time is your thanks to Yamaha’s easy-to-use features.


Powerful, transportable, exquisite, and loaded with outstanding features is the EF2000iS Inverter Generator. Recreational pursuits, including camping, fishing, and boating, are perfect for this all-around best seller.

It is also a fantastic camper-trailer partner. Microwaves, camping refrigerators, portable air conditioners, kettles, and televisions may all be powered by the EF2000iS.  Due to its innovative Quiet Block sound reduction technology, you may carry on conversations without raising your voice thanks to its newly developed muffler and air filter, which provide exceptionally silent performance.

Additionally comes with TwinTech Parallel Use capability, which, when used with two EF2000iS, virtually doubles power!

Generac engine

A recoil starter powers the 79cc Yamaha engine. It contains Engine, OHV. With the twin-tech characteristics, you may combine two EF 2000s that are compatible and generate up to Thirty amperages.

TwinTech II cable, also known as Sidewinder cable, is an attachment that must be connected. It is sold through Yamaha dealers all over the country and on Amazon. To assist in carrying heavy loads straight away, the auto warm-up limits engine speed at startup. In the event of a surge, an electrical overload breaker guards against generator failure.

Easy to set up

In addition to being portable, the Yamaha EF2000iSv2 is simple to operate.

Given that this tiny dog can produce 2000 watts of electricity, it is surprisingly lightweight at 44 lbs. If two persons are required, they may simply grip and carry it jointly, thanks to the extra-large handle. Because of its small size (2.2 cubic feet), it is convenient to travel and store.

Easy to set up

The Yamaha EF2000iSv2 includes an electric overload switch mechanism so that the machine will not run if you connect items with higher power demands than it can handle. It is intended to safeguard the generator engine against operator mistakes, extending engine life.

It protects you against unintentionally harming gadgets by overloading them with power. Buyers who have reviewed this generator have said that it is easy to install and that the guidelines are completely obvious.

Hour meter

When it is time to refill, the simple-to-read fuel hour meter will tell you. When powered at half-speed (run speed), the 1.1-gallon gasoline tank will last you 8 to 9 hours. Given the EF2000iSV2’s tiny size and low noise level, that is a significant amount of power output.

Noise level

No one enjoys listening to a generator’s engine. You are probably searching for a generator that makes the least amount of noise possible because of this. Gas-powered portable generators that are quiet are unfortunately nonexistent. The only silent devices are solar-powered ones. However, due to their light power output, they are only helpful for small-scale applications (such as charging phones or computers at camping).

The awesome thing is that inverter generators often produce much less noise than their traditional portable equivalents. We can confidently say that the Yamaha EF2000iSv2 is among the quietest inverters available. It barely makes 51.5 dB of noise while operating at 25% load. This feels like a vibrant chat between two individuals.

You will not hear much if anything when relaxing in your RV in the evening while the generator is working outside if you choose to utilize this generator in an RV park. In fact, it is so silent that the US Forest Service approved its use at campgrounds during the ostensibly “non-silent” hours.


The California Air Resources Board and the EPA have given Yamaha generators the highest ratings for emission engine durability (CARB). If you know anything about California, you know that it has very severe regulations on toxins. Therefore, this generator should be proud of its CARB certification.


All generator engines in the Yamaha EF2000iSV2 series leave the factory EPA-compliant and at factory spec. With most rival goods being rated at 200 hours, Yamaha’s 500-hour enhanced rating leads the market.

Yamaha EF2000iSV2 Vs Honda EU2200i

Honda is without a doubt Yamaha’s major rival when it concerns inverter generators. One of the earliest inverter generators on the market, Honda’s previous model, the EU2000i, immediately won the hearts of its users. Later, a more practical variant, the EU2200i, took its place. With the Yamaha EF2000iSV2, how does it compare?

Yamaha EF2000iSv2 is nicer than Honda at first glance. It is also lighter and simpler to transport. The two generators run pretty quietly. But Yamaha has a minor advantage over the competition since it is quieter at larger loads.

Yamaha’s wattage is surpassed by the new EU2200i. Even if there is not much of a difference—200 watts—Honda is still somewhat superior to its rivals. The pricing is identical, as well. Depending on the dealer, Yamaha does nevertheless often sell for a little less.

Yamaha EF2000iSV2 Vs Honda EU2200i

Standard unleaded gasoline is used to power both generators. But this is where the Yamaha EF2200iS stands out from the competition: with a gasoline tank size of 4.7 liters, it can operate for an amazing 10.5 hours at 1/4 load. In contrast, the Honda only has a 3.6-liter gasoline tank and only operates for 8.1 hrs at 1/4 load.

With the Yamaha, you get a full two hours of additional runtime. In general, both generators are excellent choices, while the Honda model may edge out the competition somewhat in terms of construction durability. A usual conversation would be louder than the Yamaha’s operating range of 57 to 65 dBA, making it ideal for fading into the background.

We face a problem since Honda rates the Honda EU2200iS Generator using a different metric, making it difficult to compare the volume. Although they claim it is “whisper quiet,” we can tell you that it is rated at LwA 90dB(A). In terms of weight basis, the Yamaha 2200W generator weighs 25.04kg as opposed to 21.10kg for the Honda. To be honest, a compact and lightweight generator that is under 25 kg is a really good choice for such strong engines.

The Yamaha EF2000ivs2 has an ingenious tri-handle design making it simple to divide the weight while operating the machine.

Yamaha EF2000ivs2 Review – FAQs
