Yamaha EF2000IS Review – Cons

Like all good things, nothing is perfect, and the same can be said of this inverter generator. Here are the most common complaints, although no one felt these issues were important enough that they would have purchased a different model.Yamaha Ef2000is generator review

The biggest complaint with the Yamaha 2000 was that it ships without engine oil.  To begin using it, you will need to add four cycle engine oil (10w30), which is not included. For most, this is no big deal, but it is something to be aware of if you do not normally stock oil. It will use less than a quart. There were also complaints about the angle of the oil fill hole being difficult to access.

The other biggest complaint…Price! Most were simply not expecting to pay this kind of money for a generator. But, they enjoyed accepting the compliments about how quiet it was and accessing it so easily because it is very portable. Overall, the Yamaha ef2000is is a model that will last long enough to allow you to get over the sticker shock.

Also, be aware that a generator can loose effectiveness at higher altitudes. Approximately 3 feet per 1000 feet of elevation, and this applies to all models.

Lastly, don’t expect miracles. This unit is not designed to run your air conditioning, heat your water, and run 2 TV’s all at the same time. But, it will get your hair dry, check your email, and charge batteries. All done quietly.
