Yamaha EF2000iS: 2000 Watts Of Portable Power

Yamaha EF2000iS Inverter GeneratorNormally when anything is created to get a good blend of many qualities, it ends up being mediocre in all aspects–unless it is the Yamaha EF2000iS. The Yamaha EF2000iS Inverter Generator seems to have hit “the sweet spot” when combining power delivery, portability, versatility, noise reduction, and ease of use. In all of these critical areas, the Yamaha EF2000iS generator earns impressive marks.

Power delivery is the primary reason for any generator, and the EF2000iS supplies it generously. With a maximum rating of 2000 watts, this little blue beauty has enough power to run most of the largest loads you could think to plug into it. This available wattage can easily run a blow dryer or space heater to warm your tent or RV and to dry out wet clothing and gear. The Yamaha EF2000iS is capable of running power tools on remote job sites, as well as radios and TV’s. At the race track, marina, in your garage or on the road, you will have convenient access to battery charging for any vehicle thanks to its eight amp, 12 volt DC outlet and included cables.

For your job site, perhaps 2000 watts is not enough to run larger industrial tools or the multiple power tools your crew will be plugging in. A simple solution might be to buy two Yamaha EF2000iS generators and link them together. The Twin Tech capability allows you to connect two generators for a combined 3600 watts of on-demand portable power (maximum 30 amps).

Quiet is a precious commodity in many settings. With the EF2000iS, you will not have to trade peace and quiet for power. The efficient muffler (which also features a spark arrester for safety), Noise Block sound reduction system, and rubber vibration isolation feet combine to make the EF2000iS surprisingly quiet. You’ll find yourself tuning out the remaining noise shortly after taking a few steps away from it. Think about what an advantage this is when camping in a pristine wilderness, or supplying power for lights and music at an outdoor party or wedding reception.

At 44 pounds, just over 50 pounds when full of fuel and 4-stroke motor oil, the Yamaha EF2000iS is very portable. It is roughly a little larger than a milk crate, but is sleek in its design and comes with a large handle for easy carrying. The Yamaha EF2000iS fits neatly into any trunk or truck. Also, the Yamaha EF2000iS generator is very user friendly.

The clear, easy to understand controls are all on the face of the generator, not scattered around on the sides and back. You will appreciate the fuel gage, absent on many other generators, which lets you know exactly when to add gas. That is, unless you like guessing perhaps betting on when the fuel will run out. Combined with the oil warning light and the Pulse Width Modulation control, you will have piece of mind both in operating the generator and using it to power your laptop and other electronic devices.

At one quarter of its rated load, you can expect over 10 hours of continuous operation. This equals long periods of hands-off power delivery while camping, working, or emergency use during power outages.

The Yamaha EF2000iS price is reasonable when you consider how much and how well power is delivered by such a small device. The suggested retail price is $1099. However, you can save a lot of money through offers on Amazon or other websites. However, when you buy Yamaha EF2000iS second-hand for your camping or work arsenal, weigh the difference in the money you save versus the value of a 3-year limited warranty.

Here Is What One of the Users Had to Say About The Yamaha EX2000iS

I have had this for about a month. This is a very high quality unit, nicely designed. I chose it over the Honda Eu2000i because it has a fuel gage and is a hair lighter (2 pounds), and liked the styling better. Specs are so close it’s a tie… the Yamaha unit specs a bit quieter in “eco” throttle but the Honda specs a bit quieter at full power. Prior to this purchase I had bought a Honeywell inverter generator (a much less expensive Chinese-made knock-off) from Costco which I returned, because I was unimpressed with the Honeywell unit’s quality and noise level. While the price difference is major, you get what you pay for in this case. Anyone looking at the cheaper knock-offs should really consider that a 5db increase in noise level is about twice as loud, the way humans perceive it…(trisailor)
