Yamaha EF2000ISV2 Review (Is it Good?)

Yamaha products are known worldwide for their high-quality performance. It’s clear that Yamaha has an established legacy of producing quality goods. Like all other Yamaha products, their generators are world-class. You will get consistency and smooth performance from the Yamaha generator. 

But the question is, are all the Yahama generators good? There are so many generator brands available in the market. You will get a reliable portable inverter generator on a tight budget

In this article, I will walk you through the review of the Yamaha EF2000ISV2 and compare them with its competitors. Without further ado, let’s get started.  

Are Yamaha Generators Made in China?

This is a burning question among users. According to the Yamaha official site, their headquarter is in Japan. Most of the generators are built in Japan. But after the tsunami in 2011, like all other companies, they expanded their business in China. Now some of the generators are made in China now. 

Are Yamaha Generators Quiet?

Yes, Yamaha inverter generators are quiet in operation. It depends on the load and size of the generator also. You know inverter generators are quiet. So if you consider the inverter generator, the noise level is miserable in the case of the Yamaha inverter generator. 

Some particular models are so quiet that you cannot understand whether your generator is running or not. For example, the Yamaha EF2000ISV2 produces only 51.5 dBA to 61 dBA at 25% load. So this is super quiet like the Honda or Westinghouse inverter generator.

Is it possible to use this generator to power tools, such as saws, nails, and nail guns at a small job site?

Yes, in most cases, you can run your small power tools. You could do a small calculation. Multiply the amps of the tools with 120 volts. That means if your tool is 5 amps, the wattage is 5*120= 600 watts. 

How can I secure the generator? 

It doesn’t include any enclosure or lock. You could use a bicycle lock to safeguard your generator. Also, you could use an enclosure to run your generator as it is an outdoor unit.
