With over 100 years of history, Yamaha is a name to reckon with. Known for producing automobiles, the company is also making use of its small engine technology to come up with new and innovative portable generators. These small generators are powerful and suitable for both indoor and outdoor use.

Yamaha’s ‘I’ line of generators use pure sine wave technology to produce clean power. The ‘I’ stands for ‘inverter’ and indicates a powerful unit. In this review, we’ll talk about Yamaha EF2000iSv2.

It is a gas powered inverter generator with a power output of 2000 watts and operating time of 10.5 hours on a full tank.

At full load, it delivers 13.3 to 16.7 Amps (120V) which is enough to handle a variety of appliances.

Yamaha EF2000iSv2 Inverter Generator Features:

  • Engine: It has a 4 stroke 79cc displacement OHV single cylinder engine with cast iron liner. It is not only powerful and efficient but also highly durable and long-lasting.
  • Maximum Power: The maximum output is 2,000 watt (16.7 amps) at startup. It offers a stabilized rated output of 1600 Watts (13.3 amps). That’s enough power to operate some big appliances including refrigerators.
  • Starting: Yamaha EF2000iSv2 has a manual recoil startup. You’ll have to pull the cable to start the generator. Do not let it scare you. The generator uses Yamaha’s popular auto-decompression system that makes it easier to start the engine even when the weather is cold.
  • Operating Time: It can run up for 10.5 hours at quarter loud on a single gallon of fuel. You can sleep comfortably without having to worry about changing fuel or the engine shutting off.
  • Fuel Efficient with Smart Throttle: Dual coil alternator stator lowers engine speed and makes the engine efficient by using less fuel. It adjusts speed according to the load helping you save money.
  • Ultra-Quiet: Do not worry about having to handle a lot of noise as the generator is not noisy at all. In fact, it operates at 51 decibels at 25% loud. The generator will not be a nuisance even at a full-load where the noise goes only as high as 61 decibels, which is still not too loud.
  • Oil Watch Warning System: The unit will alert you when it’s time to change the oil. This is a very important feature to maintain the generator as low oil can cause the system to malfunction.

​PROS

  • ​You can close the vent cap to prevent spills.
  • ​Portable and quite easy to carry as it weighs just 44 pounds.
  • ​Durable and comes with a three-year warranty
  • ​Fuel efficient, silent, and environmentally friendly.
  • ​It’s safe to use as it causes no dips or uneven output thanks to pure sine wave output.
  • ​You can pair two Yamaha generators to increase output.

​CONS

  • ​It doesn’t support high voltage appliances like air conditioners.
  • ​Doesn’t have an electric start feature making the generator difficult to start.
  • ​Starter cable can wear over time.
  • ​No LCD screen.

​Yamaha EF2000iSv2 Inverter Generator Review: FAQ

​Q. it easy to use?

Ans. The cord system may sound intimidating but this generator has an auto decompression system which makes starting the generator by pulling the cable much easier.

You will not have to try a lot as the generator will start the first time. Also, don’t let winters scare you. It works equally well in winters and does not require a lot of effort to start thanks to the auto warmup feature.

Moreover, it’s also quite easy to take care of thanks to the fuel gauge that helps keep an eye on fuel levels so you know when to refill. You will also face no trouble in starting the unit after extended storage thanks to carb drain and fuel shutoff features.

​Q. Is it environmental friendly?

Ans. With the highest EPA rating, the generator is environmentally friendly. You can keep it indoors but make sure to not sit around it when it’s operational as it still produces harmful gases.

​Q. Is it easy to maintain?

Ans. You will have to add oil when you use it for the first time but that’s not much of an issue since it comes with a manual which explains the timely maintenance routine.

The manual includes instructions on how to change oil, replace spark plugs and fuel filters. The generator does not require heavy maintenance. However, make sure to only take it to a Yamaha authorized service provider if it needs repairs.

Note: The warranty can become void if you install non-Yamaha parts or do not follow instructions.

​Conclusion

Despite its small size, the Yamaha EF2000iSv2 Inverter Generator is quite powerful. It works silently and is quite safe to use as well. However, it cannot handle big appliances. Go for this one if you need a portable generator to run small appliances.

Champion Power Equipment Hybrid Generator Review: FAQ

​Q. How can I improve run-time?

Ans. You have two options:

Connect two units to increase power. This would allow you to even run bigger appliances without any trouble.

Run it at reduced capacity to increase run-time. However, reduced power means you will not be able to run heavy appliances.

​Q. Is it enclosed?

Ans. This generator is not enclosed like most inverter generators and has a steel frame instead. This makes the generator look like a conventional generator unlike other inverter generators out there. However, don’t let it scare you as the generator is still very quiet.

​Q. Are there special considerations?

Ans. The company recommends to first run the generator for about five hours using Oil SAE 10W-30. You can then change the oil.

​Q. Can I run it in rainy conditions?

Ans. Yes, it can if you purchase the storm shield. It consists of frame rods that can handle tough weather conditions without affecting the natural flow of air.

Other than this, you can also purchase a cover to prevent dirt and dust.

​​Q. How altitude affects this generator?

Ans. You should swap the main jet with the altitude jet if you are 1,000ft above sea level.

Not doing so can cause the generator to malfunction. Similarly, switch back to the main jet once you get lower.

​Conclusion:

Champion 100302 3500W can be a good option if you want a generator that’s reliable but not too big or powerful. While it does lack a few features, the benefits are still there. Plus, it’s affordable as well.
