Yamaha EF2000iS Inverter Generator Review Photos
Electricity Produce
This advanced model of Yamaha boasts of an AC output of 1600 to 2000 watts and an AC current of 13.3 to 16.7 amps at 120 volts. These are impressive figures because the units of AC produced are relatively higher than the output of other I-Gs under different brands. The electric current is also guaranteed cleaner because the Yamaha EF2000i inverter generator emits pure sine waves. No need to worry about the possibility of overload because the unit contains an overload breaker that will take care of any unexpected power outburst.
Noise Level
Compared to a high-end model from Honda, the Yamaha EF2000iS works more quietly especially on an eco throttle mode. Even if the device is turned up at a full engine speed, the noise produced will not require you to raise your voice in order to have a decent conversation. You can even talk on the phone without experiencing any distraction. The super-quiet muffler installed inside the Yamaha EF2000iS makes this unit a silent workaholic, producing only 51.5 decibel of sound at a quarter load.
Fuel Efficiency
Households all over the world have chosen to switch to inverter generators because of the fuel efficiency that’s absolutely better than a basic generator. You’ll be glad to hear that Yamaha EF2000iS comes with a Smart Throttle setting that regulates the engine speed depending on the load or frequency requirement. If the load is lower, the engine adapts to its phase, thus decreasing the fuel consumption. This technology also helps in reducing the noise level of the unit as it promotes fuel efficiency. You can actually turn it on for solid ten hours and a half on full tank without the need to add extra fuel.
Portability and Convenience
Just looking at the photos of Yamaha EF2000iS will convince you that the unit is very easy to handle. It weighs a little over 40 pounds, relatively lighter than other units with comparable specs. It’s also easy to store and convenient to carry from one place to another with the measurements of 19.3 in x 11.0 in x 17.9 in (length x width x height).
If you use it outdoors, you don’t need to worry about running out of fuel because there’s a warning system that gives you all the information about the generator’s fuel condition. It will tell you if you need an additional fuel to run the generator.
