They are so the same

The Yamaha EF2000iS and Honda’s equivalent generator, the EU2000i, are remarkably similar. They both have the same power output, both use about the same amount of fuel, and both the Yamaha and Honda are able to link with another of the same model to increase power output.

Both of these generators make excellent portable power solutions. In fact, without digging into highly technical details so similar to be of no consequence, the only obvious difference between the two is the color. Yamaha went with its quintessential bright blue, and Honda, predictably, made its generator red.


Comparation on price, ease of use, included accessories and value

But the Yamaha EF2000iS portable generator is better for several reasons, beyond the striking aesthetic quality and blue color that trumps Honda. The reasons are as follows:

  • Yamaha’s EF2000iS generator is easier to maintain. While the Honda calls for an extensive combustion chamber cleaning after only 300 hours of use, the Yamaha simply needs its head cleaned after 300 hours of use or once per year. Honda’s generator also calls for an air filter service every three months, while the EF2000iS only requires such servicing every six months.
  • While both generators are able to charge 12 volt batteries, Yamaha thoughtfully included the battery cables as standard equipment with the EF000iS. Honda’s EU2000i does not ship with the cables. So, either don’t forget to special order the cables, or simply buy the Yamaha.
  • Both are comparable in price, however the Yamaha’s MSRP is lower with 10%discount from amazon. Also, for the base price, Yamaha includes battery cables.
  • The Yamaha EF2000iS will run nearly an hour longer on the same 1.1 gallon tank capacity at a quarter rated load than the Honda EU2000i
  • The Yamaha EF2000iS is over two pounds lighter than Honda’s EU2000i


Deeper Compare

However , it is still a hard decision for your to make if you only find ef2000is is just a little quieter or lighter than eu2000is, two pounds is not the reason you buy a Yamaha ef2000is.
