The Yamaha EF1000iS receives an excellent rating of 4.5 stars out of 5 to prove how good the product is. Here is what the customers has to say about this portable generator,


– It is extremely quiet, just slightly louder than that of a good refrigerator. This not only makes it quiet, it cuts back on fumes, and saves gas.

– Very small gasoline consumption. A tank filling can last half a day easily depending on demand.

– Light weight. Compared to taking the 5000W generator to camping, the small size and light weight are a welcome change.

– Well built engine. Although only 50cc, it has overhead valves and excellent sound isolation.

– Clean power. Because the alternator is outputting a DC voltage into a sine wave inverter your 110 VAC is coming from one of the best sources.


– It’s not going to run EVERYTHING in your RV at the same time. Consider your loads and if you must run everything simultaneously.

– Heavy loads make it spin faster and thus change the acoustic tone of the exhaust.
