Yamaha EF2000iS

If you're looking for a reliable energy source for your weekend camping or short term power outage needs, then the Yamaha EF2000iS Gas Powered Inverter Generator is definitely one item that you will want to put on your shopping list. There are a number of great things about this particular Yamaha generator that can help you when you need it most.

One thing that you'll find right away is that the Yamaha EF2000iS does not lack power because it is capable of outputting over 2000 watts of clean AC power which is more than enough to power many of the items in your home or on the job site. The generator can run for a long period of time and still provide a great deal of power. On average, the generator can sustain power for over 10 hours on a full tank of gas.

Often times when a generator runs that long, there is the issue of burning up too much oil which can lead to engine damage. The EF2000iS comes equipped with a low oil indicator light so you know exactly when to add more oil to the generator in order to prevent any major engine damage from occurring.


The engine in the EF2000iS is highly efficient and runs at optimal engine heat levels. This ensures longer engine life and sustainable performance over many years. Another reasons why this particular generator runs so efficiently is because of the Smart Throttle Load feature which automatically adjusts engine speed based on power output. If more draw is being placed on the generator, then the engine will speed up in order to accommodate for it. If less draw is being placed on the generator, the engine will slow down to idle speed in order to conserve fuel to ensure longer run time.

The generator is very user friendly thanks to the centrally located, easy to read control panel. User friendliness is often times an issue with this type of equipment, but Yamaha does an excellent job of taking into account the fact that not everybody has had a ton of experience with this type of equipment, which is why you see the high ease of use factor coming into play with this particular model.
