Product Description

Yamaha EF2000iS belongs to the new generation of inverter generators which can run at different speeds depending on the power output required by the user. The device is compact and light. It is packed with technologically advanced features which allow for its smooth and efficient operation and which protect it from damage and from natural wear and tear.

Features of the Yamaha EF2000iS Portable Inverter Generator

Yamaha EF2000iS Generator measures 19.3 by 11 by 17.9 inches. It is one of the most compact devices available on the market. It weighs just 44.1 pounds. This is around four times less than the average generator. The thing that impresses me the most is that the device has the design of a miniature suitcase. It has a durable plastic handle that allows you to carry it by hand to the place where it will be used easily and quickly.

The OHV 4-stroke gas powered engine of the portable power generator has a single cylinder. It is air cooled. Its displacement is 97 cc. It produces a rated output of 1,600 watts and maximum output of 2,000 watt.

The inverter system of this portable generator is perhaps its most valuable feature. The Yamaha engineers have even integrated pulse width modulation control for greater efficiency of this system. Thanks to the inverter system this 2000 watt inverter generator produces pure sine waves. These are much cleaner than the ones produced by traditional generators. As a result, the produced AC output can be used to power even devices with highly sensitive electronics. These items will operate smoothly with the risk of damaged being reduced to virtually zero.

There are different features of the Yamaha 2000 Watt Generator that are designed to make it highly energy efficient. The Smart Throttle Load feature adjusts the speed at which the engine works in line with the output that you, as the user, require. This allows for more efficient fuel consumption and for lower operating costs. The dual coil alternator stator helps for the lowering of the engine speed and consequently for even greater energy efficiency. I certainly appreciate the fact that the generator comes with an economy mode given the fluctuating gas prices.

The control panel is fairly compact. It is found on the side of the portable power generator. The controls are really simple to use, even for people who are not technically inclined like some of my employees.

The auto-decompression system of Yamaha EF2000iS Inverter Generator makes it start fairly quick, quite easy and, most importantly, smooth. It automatically reduces the compression allowing you to start using the device straight away. The TwinTech technology is another functional feature. It enables you to connect two of these portable power generators together and use them to power devices, which consume more energy, more quickly.

The generator comes with a range of noise reducing features. The muffler is designed to operate very quietly. The entire design is made to block the noise. This is aided by the glass wool construction of the device. Finally, the feet of the case isolate the vibrations to provide for the quietest operation possible.

The main safety features of the portable power generator include spark arrestor, designed to prevent sparks from exiting the exhaust system and causing fire, electrical overload breaker for preventing internal damage, and an oil watch warning system which is designed to ensure the optimal operation of the device in the long term.

Capabilities

Yamaha EF2000iS GeneratorYamaha EF2000iS is rated at 1,600 watt output, but it can produce as much as 2,000 watts. You can always pair it with another generator from the same model to get double the amount of power. In general, the output from a single device should be sufficient for powering a number of appliances and/or devices that you need to use. The 8A12V DC output produced by the generator enables you to power rechargeable batteries as well.

The generator can operate continuously for 10.5 hours at 25 per cent rated load. I can safely say that this is quite a long time for such a small and compact device. I find this capability particularly useful.

Suitability

This 2000 watt generator is quite versatile so it can be used in many different ways. You can use it as backup for power outages in your home or in an office. It can be used to power all kinds of tools. You can use the Yamaha inverter generator when going camping. You can charge RV, auto and boat batteries.

Pros

I can outline a number of benefits of Yamaha EF2000iS:

  • Compact, lightweight and extremely easy to carry around – you can take this portable power generator anywhere with you
  • Protects devices with sensitive electronics by providing clean AC current
  • Energy efficiency – you will save a lot on fuel
  • Effective protection from damage and accidents
  • Versatility – you can use the generator to power all sorts of appliances, electronic devices and tools and even to charge batteries
  • 2-year warranty
  • CARB compliancy – you can use this device in all states of the USA

Cons

There are two drawbacks I managed to find, but I do not think they are substantial:

  • The warranty is somewhat more restrictive than I would like it to be, but it is still fairly extensive.
  • The output could have been higher so that pairing two devices would not be necessary when you need more power.

Conclusion

My verdict is that the Yamaha EF2000iS 2000 Watt 79cc OHV 4-Stroke gas portable inverter generator is a versatile and functional solution for homeowners, businesses, contractors and everyone who loves recreational activities. You should certainly consider this model as it is durable, reliable, and easy to use and energy efficient.
