Yamaha EF2000iS vs EF2000iSv2 Super Quiet Inverter Generator Review

By Jack | Updated: August 22, 2018

Our family loves to go on outings and camping, and so I decided to get this Yamaha EF2000iS Inverter Generator for such applications.

Whenever we go to a remote area where we would find no power source, I put this portable and efficient generator in my truck.

I have also used it when we go fishing with my buddies too.

Yamaha EF2000iS Super Quiet Inverter GeneratorSo, if you are also in search of a suitable generator for your camping, boating and even construction uses, I suggest you get this and enjoy its performance.


Quiet And Efficient

This inverter generator can generate 1600 watts running power with a maximum output of 2000 watts.

The innovative inverter technology makes use of cleaner electricity in the form of pure sine waves.

This way, you don’t have to look back on the damage that can inflict by unrefined energy. There is an overload breaker to minimize damage to the device in case of a sudden overload.

It’s a very efficient portable generator that has a throttle system for adjusting the speed of the motor to compensate for the power output.

You can be assured of efficient fuel use with this feature. This makes everything easy for you so you will have optimal convenience when using this generator.


10 Hour Run

The OHV engine is not only fuel efficient. It can run up to more than 10 hours without refueling. Heat is well-dissipated, so that the machine does not overheat, and it lasts longer.

Startup of the motor is not difficult; thanks to the auto-decompression system.

The TwinTech technology employed in this device allows you to connect it with another generator for higher output. This parallel function of the Yamaha EF2000iS is indeed a great help if you need more power for your applications.

You can run two units at the same time to produce up to 30 amperes.

When you are using it for heavy-duty operation, you might be concerned about the noise it might make. Well, the glass wool construction helps cut down the noise produced by the generator.

You won’t have to worry about the noise of this generator. Also, there are vibration-absorbing feet to keep noise and vibrations to a minimum level.

When we go to one of our trips, we really appreciate the compact and easy-to-carry design of the generator. We could even recharge our 8A 12V batteries with it!

These features really made me recommend this portable generator from Yamaha.

EF2000iS is available in Blue and Camouflage finish.

Customer Reviews

Yamaha is one of the most reliable companies in the modern world of electronic producers. So it comes off as no surprise that the Yamaha EF2000iS has gained nothing but good comments from the general public.

Fans have loved this fuel-powered portable generator for its powerful service, continuous backup, and quietness when performing its roles. It uses up less energy compared to the fantastic output.

However, nearly all the complaints regarding the EF2000iS performance, are due to its apparent lack of durability, as few models have been known to stop working even before the end of the warranty period.


This model is still available from Amazon, but you should check if the price is reasonable. Maybe WEN 56200i, Honda EU2200i or Westinghouse WH2200iXLT would be a wiser choice.
