Here is a full review of how we think this generator performs:

  1. Ultra Portable – This is the lightweight option. You can carry it with you anywhere. At 55 pounds, it is ultra portable and can be hand carried taken to boats, camp sites, and can also serve as backup power at home.
  2. Fuel Efficient – The print says it is fuel efficient and can stay running for up to 10 and a half hours. The EF2000iS was specifically designed to make this generator respond to electric back up needs without dissipating efficiency. It dynamically adjusts to the needs of the user. The dual coil alternator stator lowers engine speed which reduces fuel consumption. This technology is what makes this generator system worth purchasing.
  3. Run Time – Surprisingly a small Yamaha 2000 generator like this can run up to 10 and a half hours. We were surprised that the print actually is close enough to what it promises. The run time is definitely a good purchase factor in this generator system.
  4. Design – The design is ergonomic that you can carry it like a bag. With its easy-to-carry design, you can conveniently carry it with you anywhere. Its push start button makes it start up very easily. All controls are on one side which makes it easier for the user to control the generator. The fuel gauge is easy to read which you won’t see on a Honda.
  5. Minimal Noise – It has noise reduction technology built within the system that makes it absorb the noise it produces. The glass wool construction helps in dampening the noise. The generator set is really, really quiet at all speeds.
  6. Dual Generator option – If you want more power, you can connect two Yamaha ef generators. You can hook up two generators to power up more appliances. This is also know as running generators in parallel.


  1. Price – Downside, it costs a lot of money. With the technology put in this generator, you won’t be able to buy this cheap. There certainly are cheaper generators available, but not of this caliber.You can rely on the brand name and the technology its engineers have invested in it but it will also drill a hole in your pocket.
  2. Reliability – After a couple of uses it seems to be less reliable. The oil spills on the side, the run time is lesser than the print. There are some defective yamaha ef2000is for sale out in the market. They should recall them and give a replacement. A thousand dollar investment is no joke and you should be able to rely on it.
  3. Warranty along with Poor Service – Warranty is supposed to be 3 years but when you call Yamaha to help you out; their response time is slow which makes the warranty almost consumed while the unit is not maximized for use.

Overall Impression

There are different Yamaha generator reviews out online but if you look at the very point of each of the reviews it all boils down to this: Yamaha is technology driven, expensive and still needs improvement in terms of service. Overall, it is impressive because of its portability but questionable in its reliability. Make sure you take good care of the unit so that you won’t have problems with replacing it or repairing it. This is not to be compared to Chinese knock off generators though. It is no comparison to them in terms of the noise and weight factors.
