Yamaha EF2000iS Review

Engine Displacement & Power Output

79cc with four strokes and awesome efficiency of 2000 watts. But keep in mind, that 2000watts is a peak power, and steady output equals 1600 watts. This is an inverter generator, which means you can use it to power your sensitive gadgets and other appliances.
This is not the generator for general backup. You won’t be able to power your home or something heavy. Small sized devices show their best outside.

Runtime & Fuel Type

As you already know, the size of this model is rather small, so you should not expect a big tank. But no worries, 1.1 gallon gas tank is more than enough for 10 hours on a quarter load.

Start Type

This is not the top of the line generator, but yamaha 2000 inverter generator will start nice and easy, right out of the box, just pull the chord and get going.

Noise Level

The generator is small, that is why the noise level is incredibly low. Moreover, thanks to the innovative muffler, the generator is 61db loud at max. This is really quiet (you may not hear it).

Size & Portability

Yamaha ef2000is is a highly portable 44 pounds model. Measurements are comfortable for moving around: 19.4×11.0x17.9 inches in length/width/heighth.

And such parameters make it almost pocket-like, even a child can move it.

Product Warranty

3 years spreading across all Yamaha products will keep you covered in case of any issues.

Price & Value

Yamaha is not the cheapest brand. The quality, silent running and basically lack of any problems cost a good buck. I still recommend Yamaha.

Yamaha EF6300iSDE


Yamaha is not stepping off their policy of quality and price. Today we will be talking about new EF6300iSDE portable generator of the future.

Okay, that was a bit of extortion, but you will get our drift in a few. Our crew went on searching for a perfect engine for our hefty environment. So when we went shopping for the new review, we stumbled upon this model and bought it. We were really surprised with the entire wattage and small size, and since this is Yamaha, we couldn’t pass up such interesting unit. So we took it home, brought it together and started testing. And since we live in the middle of nowhere, power downs are quite issues, but this time it wasn’t a problem what so ever. We worked late that night, and our construction shop was running just fine, even without any power in the area. Trust us, jealousy and anger of our neighbors was priceless. But jokes aside, let us get started on the actual peace by peace review.

Yamaha EF6300iSDE Review


So, let us take a more detailed look on our new engine, on our behalf, we are sure you will love it just as much as our crew did. And to prove you our point, we gathered personal experience and some notes from outer world just for you:
This unit has more than satisfying power level: you can run blowers, pumps, ac units, heating system and so on. In comparison to most generators, this one is actually pretty small and quiet, so you can use it not only for home use, but also for camping and outdoor activity. You can actually bring it out to the wedding tent in the yard and you will have no problem with it. The basic current flow is at a respectable 5500 watts, which is more than okay. Besides, any sensitive systems you might attach it to, can be safe and sound, because the inverter type of engine does not allow any power jumps and burn outs.
Running time is more than enough for most needs. You can make it run for 13 hours at one fourth of the load. So you can easily leave it overnight and go on with sleeping. Also this unit includes 4.5 gallons tan and it has one of the highest efficiency on the market.
Starting type is a classical pulling chord or more comfortable button. You can use some power to pull the chord (especially when it is just right out of the box) or just press the button once the battery is fully charged and ready to use.



Noise power is more than bearable. We should remember that this unit is capable of producing more than 6000 watts, thus sound level is between 58 and 64db . This is a low as a normal human conversation, but sure, the fewer loads is in it the quitter the noise level. Logic, eh. Perfect for camping and outdoor use, also you can technically fit it in your RV.
To be honest, there is no such thing as small 6k+ watts generator, but if you are planning on buying this mode; you will be surprised with its more or less portable design. Measurements are pretty awesome: 30.7×24.3×27.2 and about 200 pounds of dry weight.
We had a bit of issue with the pricing, but hey, some things are worth its overall price and this generator is no exception. For some 3800 dollars can be a bit much, but still, it did all and more for his price. We are okay with this price, because we didn’t have any need in bulky stationary generator, so, no wonder we chose something more decent. Besides, 6300 watts is somewhat in this price range. Oh yes, this also covers the 3 years warranty included from the Yamaha company.


As for the reviews, be found the impressive rate of 4.7 out of 5 stars, thus giving us a good reason why for buying this device. Most of reviewers were very happy with the power efficiency, speed and other important features of this generator. Also, just like we did, reviewers enjoyed having an easy to start power mechanism and high quality construction. Though we did have some small odds with the servicing, but once you get used to it problem is solved.

More things to show off:
-Noise block for silent work
-CARB and EPA approved
-Fuel efficiency mechanism
-Wireless remote for controlling your generator
-Oil shutoff mechanism
-Power meter for indicating general power
-Time meter for tracking general time of use


Cons and pros:

Can power any high-demanding tool
Can deal with both 120 and 240V units
Quiet running
Can be used nationwide thanks to the CARB-compliance
Made out of top-quality materials
Not the cheapest one
Can be a bit of a problem in servicing because of small size

Yamaha EF2400iSHC


Howdy guys. So our northern team is in search again. This time we got Yamaha EF2400iSHC in our hands. Yamaha is famous for quality and durability of their constructions, so there is no wonder in our choice.

We were in search of something portable, and okay for any user that is not familiar with generators in general. Our goal was taking it out for a spin in RV and that is the exactly what we had done.  So we decided to share our experience with you and highlight all of the flaws and benefits of this model with you.

This engine is cooled by air, 4 strokes, steady 2000 watts and 2400 at an ignition point.

This is pretty much all you need for powering small home appliance, RV or air conditioners. Also this small thing can power pumps, microwaves and some construction tools. And why is it capable of doing so? Well, inverter generators provide steady current, so you can connect any device to it and use them with no problem.


This generator is perfection for those who have some issues with fuel. It shows small appetite for fuel, can run for 9 hours at a one fourth of the entire tank. And in general you will be able to keep moving on without any refills for quite some time. It has a smart electronics to maintain the same amount of fuel on board. But as a con of sort you can say that manual start is not always the best thing. Also if you are sleeping out in the tent, you will sleep well, because this generator is max 60db loud and min 53, so you will practically it in silence. And also it adds some pluses to your karma, because you neighbors at a campsite won’t try to kill you.

This model is small and lightweight, so you can take it everywhere you need. 75 pounds, 20.8 by 16.5 by 18.2 inches and can power an air conditioner in RV.  This generator is an awesome combination of size, power and brand. So you are getting a good deal for good money. So, if you are planning to go for camping – this is your device.

There are three years of warranty, that you won’t use, and 1300%$ you will have to pay for it at the store. Inverter generators aren’t the cheapest, but surely worth it. If you are looking for something to compare it with, then convert your sight to Honda models.

This model is highly loved by our team and users online and offline. It gets mostly 5 out of 5 stars, so you shouldn’t worry about the quality or information about it.  You can use it in every state, it has oil shut off and it is portable. What is else there to wish for?

So what are the cons and pros?


  • -Clean power
  • -Lightweight
  • -Quiet running
  • -Fuel efficiency
  • -CARB compliant, so use it anywhere you want
  • -Solid construction


  • -Pricy in relation to some models

To sum things up we are presenting you what is in our opinion is an awesome generator. We tool it across the country, dragged it around the woods, talked to experts and generally tested the hell out of it. We liked it, but don’t expect way too much of it. This is a good generator for travelers, campers and people who want to fit things in small spaces.

It is solid in building; it is CARB compliant and pretty much perfection all around. You can connect your gadgets to it; you can make your heating system work and make your life a bit easier.

Yamaha EF2800i


We often face the question of balance between quality and price. So far, Yamaha maintained its leadership in their segment of the market and today’s topic is no exception. If you are looking for a closer look on Yamaha EF2800i then you came to the right place. Why do we need generator in the first place? Well, for example you have a power down, that makes your whole house freeze and you were in the middle of something important. Sure thing, you would be happy to unfreeze your home and finish things you have been doing. Where else you might use a generator, you might ask? Well, we all are social beings, and garden parties, weddings and so on are one of the ways of getting together. And as you can imagine, garden party means no outlets and steady current included, so this is another moment when generator comes to rescue. As for us, we live in the northern part of US, this means, that power outages are a common visitors in our region. Surely, we want to be ready for such occasions and so we bought a generator.

Yamaha EF2800i Review



Number one reason why we chose Yamaha EF2800i is the running time, which is abou 7 hours of constant work at a full load. But surely, you can make it last longer (up to 15 hours) if you set the load to one fourth of the general capacity. For comparison we tried powering chainsaw, router and vacuum cleaner all at the same time, and then added conditioner in RV and well…it did just fine. Our test has shown zero problems in such load for this generator, so this will be one of the reasons why we recommend it.

In some states, such as California, special attention is drawn to the problem of pollution and environmental friendliness, thus Yamaha made this model CARB compliant, which means that you can sell this unit in California. This is actually good news, because you are not only receiving a steady working machine with high maintenance, but also a friendly to nature device, which add a few pluses to karma in general.

There is 2800 watts in board and an AC output to add. As a note to self, count the entire appliance you are planning to use, add each of powers they use, so you won’t overwork your generator. If you are lacking some power, then consider buying another model, because it might turn into a problem in most unexpected moment.

If you are planning connecting sensitive devices to your engine, then we have more good news. As you already know, inverter generator means, that the current that this machine uses is one of the steady kind, because the transformation from AC to DC goes within the generator and provides you clean electricity with no jumps which can harm or burn your gadgets.

As for the specs you will be pleased as well: compact dimensions (15.6” W x 19.2” L x 16.7” H) and a decent weight of 64 lbls to match. As for the tank, the capacity is more than respectable for its size: 3gallons. As a bonus there is 3 years of industrial warranty to come with it, which we did not use at all.


If you are a bit stingy on financial behalf, this generator will meet your needs with no hesitation, because it allows reduction of fuel usage, and it is very vey quite. Trust me, when going out for camping or making a special event, nice background without noise is one of the keys for comfortable time passing.

Only con that we found out was a bit harsh in the price, because it is not the cheapest one out there. But, if you look around your local retailers, you might stumble upon a good deal. But even so, keep in mind, that this is an invertor generator, thus the price on similar models are high as well. But if you need quality it is okay to pay a bit more, right?


Hope our review was useful and you will come back to us for more interesting material very soon : )

Yamaha EF2400IS


Do you need a steady technology? We sure do. And now, thanks to Yamaha we have another notable representative of this generators family at our disposal. Yamaha EF2400IS is a notable representative of inverter generation. Company is highly concerned with their customers’ needs and made this generator incredibly quiet and lightweight for easy transporting. As for basic specs, they are pretty damn impressive: 59dFA max of noise production, 32 kilos of weight (about 70 pounds) and with steady 2400 watts of output.

Yamaha EF2400IS Review



To tell the truth, this combination of specs makes this small guy a powerful player on the market. Design of 2400iS is portable and ecofriendly in a way. It is CARB compliant and implements all of the possible standards of Japanese LEMA. Also it does not use any toxic materials during assembly on the factory, which goes under ISO 9001sertificate.

This machine can be recycled almost completely (97% out of the entire mechanism), thus making it a number one choice for states with high eco-culture and strict laws.

As for esthetical counterpart, smooth aluminum case, with minimalistic and yet handsome appeal will suite any household. And thanks to this design in general you shall have all of the access to important modules and switches on the side of engine. This makes servicing the engine a deal of few minutes, which may come in handy when going out in the wild or in case of emergency.

One of interesting features worth mentioning is function of parallel connection between two modules. Just connect two devices together with special kit and double the possible power without buying more expensive generator with the same output as two combined.

This magical feature allows you to run heavy weighted appliances with power of two small generators. Just connect the two and you will be all set, and without any additional hovering over the engine. This feature of non-problematic usage we can call a huge plus and use the hell out of it : )



And yes, this generator is suitable for RV’s, because it is the inverter type after all. So you can take it with you out for camping and be with all of the comfort you want around you. And because it is quite as the conversation, your camping neighbors won’t feel the sudden urge of hitting you with a log because of the noise your machine makes.

Hope our review was useful and you will come back soon for more interesting things on our website : )

Yamaha EF1000is Review

4 strokes of engines, cooled by air and has only one cylinder. This little monster is capable of 3000R per minute at one fourth (1/4) of the load. In case of oil failure, the engine will turn itself off, so you don’t need to worry about this. As for the tank there is 2.5 Liters aboard. As for the fuel, normal gasoline is just fine. Yamaha 1000 generator has the feature of automatically adjustment of the engine speed, and this will keep you covered in any way of the device use. And also this increases the efficiency of the engine and also extends the running time.


As for the running time, ef1000is is capable of working for 12 hours whole, without any refills. And also, it is not that loud, due to advanced exhaustion system.As for the electricity current, inverter generators more preferable due to the fact of more stable output. As we already mentioned,this generator is a portable thing, so don’t expect any outstanding productions, though it is capable of producing 900 watts (maximal is 1000 watts), which in some cases is enough. In comparison to the more traditional conventional generators this generator is more preferable for hight tech devices.


This small generator comes in handy when we are speaking of computers, audio and cellphones, and other electronic devices. Thanks to produced PWM the range of stability within 1% and 0.1 HZ of frequency.
Yamaha generator ef1000is has a full range of indicators, lights and switches. You will have all on oil measurements, warning lights, controlling switches and so on.

As for the feedback it received more than welcomed reviews. Amazon rates this product at 4, 4 out of 5 stars. Though not everything is all nice and shining, there are some negative reviews as well.
Some owners reported that oil change can be a challenging sometimes. When filling you might overfill the tank, and this could be an issue. Sometimes users manual can be a hard thing to deal with, well.. it is not there. At all. You will have to print it out by yourself, but this is not as bad as it sounds.
