Setup: If you are a novice, never underestimate the need to properly set-up your generator for the first time you.

You will also have to correctly breaking-in to the machine which involves first-time lubrication and oil change while the machine is running.

This is crucial as it helps dislodge metal pieces which can otherwise damage the engine. Be sure to read the instruction carefully for first-time use.

Ef2000isv2 V/S Ef2000is: What’s new in Version 2?

Although the previous version from Yamaha was equally powerful and robust, an important distinction is that the controller is more sophisticated and can be programmed with greater flexibility. This also means that you can now power a wider range of appliances with Version 2 since you have a wider range of outputs.

Pros: Being the quiet little ultra-portable engine that this is, you will love it if you often need to move the generator around and if noise is a huge concern.

Another plus point is that the output is very stable and you can power a variety of appliances, and as long you have gas available, the machine will run without any issues.

Cons: While there are no real downsides to this Yamaha generator inverter, we will grant you that it is a bit of a costly investment for someone just starting out or if you need to use it sparingly.

Also, if you are a bit lazy, you will find having to use a funnel to refuel the generator bit of a bother. Since it’s not a dual fuel generator; you might feel compelled to use gasoline, which is pricier than propane.

Competition: With all its features and specs, this inverter generator still faces fierce competition, especially from the Honda EU2200i. So how serious is this competition, you ask? Read on…

Yamaha Ef2000isv2 Vs Honda EU2200i: Which is better?

Ok, so when it comes to comparing Yamaha with Honda, we got a bit scared.  But how serious a threat is Honda EU2200i? Will red defeat blue in the clash of titans? Actually seems like Yamaha doesn’t have too much to worry about.

After being compared, both generators are faring almost equally in features like looks, low noise, compact size, and weight.

While Yamaha’s blue and Honda’s red are equally classy, Honda’s 57 dB at rated load is as quiet as Yamaha, and Honda EU2200i is just 2lbs heavier than Yamaha EF2000isv2 and almost the same size.

So do we have a tiebreaker? Well, the bottom line: the Honda EU2200i delivers 10 percent more power, albeit only gives as much as 8 hours at ¼ load.

So while both generators perform almost identically on most fronts, the Honda infact costs more. So why would one spend all the extra bucks?

It seems the price factor combined with the larger fuel reservoir, more run time and slightly less weight might just give the Yamaha EF2000isv2 the winning edge!

Before you leave…

Ok, Yamaha, we are indeed impressed; especially when you throw at us huge technical terms like “Pulse Width Modulation (PWM).” While that really just means this generator is safe for use with very sensitive appliances, let’s give that goal to you as well.

All in all the Yamaha Ef2000isv2 wins our ‘Yay’ vote by an overwhelming majority.

However, be sure you do not use a pocket knife to cut down a tree!

Meaning: use the generator for what it ought to be used for and remember that the warranty does not cover damage from lack of proper maintenance.

So, don’t blame us for our soft corner for the Yamaha EF2000isv2 generator, after all, it’s difficult not to fall in love with something so deceptively powerful concealed in something stunningly gorgeous!
