Yamaha EF2000iS 2,000 Watt 79cc OHV 4-Stroke Gas Powered Portable Inverter Generator (CARB Compliant)

Powerful, portable, and efficient, the Yamaha EF2000iS Gas-Powered Portable Inverter delivers maximum electrical output without sacrificing portability. Thanks to its innovative inverter system, the generator is able to generate up to 2,000 watts of clean AC power. It can run up to 10.5 hours continuously without refueling and uses premium technologies to maximize fuel efficiency.

Powerful Inverter System Delivers Cleaner Electricity

The EF2000iS is built around an innovative inverter system, which is able to deliver higher-quality, cleaner electricity than competing generators. It produces energy in the form of pure sine waves, which are cleaner and more reliable than most commercial power sources.

In simpler terms, this means that you'll be able to confidently power delicate machinery without having to worry about the damage caused by unrefined energy. An electrical overload breaker is also included, to prevent generator damage in case of an unexpected overload.

Smart Technologies for Optimal Fuel Efficiency

Compact and ergonomic, the EF2000iS is easy to store and transport
The EF2000iS is exceptionally fuel efficient, able to run for up to 10.5 hours without refueling when in Economy mode. Its OHV engine runs reliably and dissipates heat efficiently, allowing for both a long life and optimal fuel consumption.

With its Smart Throttle Load feature, the generator is able to dynamically adjust engine speed depending on output, resulting in greater overall fuel efficiency. The generator also features an exclusive dual coil alternator stator, which lowers engine speed and reduces total fuel consumption.

Ergonomic, User-Friendly Design
Weighing 44 pounds, the generator is ultra-portable and features an easy-to-carry design. It has a convenient, centralized control panel, which allows you to easily access all of the generator's features at the push of a button. It also starts up responsively due to its auto-decompression system, which reduces compression and makes start-up less difficult.

For added convenience, the EF2000iS is able to recharge batteries with its 8A12V DC output, making it ideal for RV, auto, and boat owners. You can even hook up two EF2000iS units for added output, thanks to TwinTech technology. And you won't have to worry about engine damage due to low oil levels: an oil-watch warning system constantly monitors oil levels and lets you know when an oil change is needed.

Noise Reduction for Quiet Operation
TwinTech technology allows you to hook up two units for added output
The EF2000iS uses noise reduction technologies to ensure the quietest operation possible. Featuring a special sound-blocking design, the generator has noise-absorbing glass wool construction, which helps dampen noise even during heavy operation. Along with the EF2000iS' super-quiet muffler and vibration-isolating feet, it helps keep noise to a minimum.

The EF2000iS is backed by a two-year warranty.

I got this primarily for my travel trailer, though it's not powerful enough to run A/C or multiple appliances. The economy mode is great since it quietly idles under light load and cranks up as needed. Filling the oil is messy - I put too much in, so a lot of it spilled and the overflow is still seeping out. Next time I'll use a turkey baster to fill the oil. I also wish that there was another way to reset the generator after an overload other than shutting it down and restarting it.

Received my new EF2000iS within 4 days of ordering which was excellant. Unboxed, and followed the instructions by putting the oil in first, and then fuel. Unit fired up on the First Crank. This Generator Far Exceeds all others which are currently for sale, not only with muffled Sound, but also generator output. This light weight unit currently out performs by Kipor 3000 watt unit which I had been using with my RV, not only by weight, but 50% less sound. I would strongly recommend this Yamaha Unit above all others.

This is the GREATEST generator ever made. I use it to power my tire warmers for my track bike and it's excellent. It's so quiet, can hear other people's generators further away before I hear this one. Matter of fact the only way I know it's still running is because the warmer light is still on.
I'm in the military and was getting ready to deploy so I had to store the generator. The instructions said to let it run dry of gas and drain the oil. So with the generator's gas guage on empty, I started it up to just let it die. This thing ran for another 2 hours until I finally gave up and turned it off. The next day with it still on empty I started it again and put a 900 Watt load on it and it STILL ran for another 3 hours until it finally started to sputter and die. This generator is AMAZING. I love it.

Has done everything I've needed it to do, December 28, 2011 By Brian

This inverter generator was purchased to run a few amps, lights, and a TV at a football tailage. Long before the first tailage there was a power outage at the house and I used the inverter generator to power a fridge in my kitchen for 4 days. Don't kid your self into thinking this is a 100% duty cycle generator, I would run it for several hours shut it down and then start it back up when the freezer got near 28*. In 4 days the generator ran for just over 40 hours and used about 4 gallons of gas.

Quick oil change and it was tailage time. And this generator shined when it came time to tailage. Running about 750w worth of amplifiers, some small lights and a 38" LCD was nothing for this little guy. When the music was turned up and the amps started hitting hard the eco mode would speed up the motor a bit. A 5 hour tailgate would use less than a 1/2 tank of fuel.

I couldn't be happier with this purchase. We've even had to use the 12v outlet to charge the tailgating trucks battery when someone forgot to turn off the headlights before kickoff.

This is a great compact generator. I really believe these products are second only to Honda. Mine however must have been defective because it started leaking gasoline a few days after I got it.

What the doctor ordered, November 28, 2011 By Mikey (Sacramento)

Was looking for a light/portable/quiet generator and found it in this one. Not sure if a inverter generator is needed but guessing its good insurance against damaging a computer or tv. Is quiet, as I can expect, for a engine running. A bit of a pain filling with oil. Like the gas petcock, so I can run the carb dry. Not sure if it will damage anything but would rather store it without gas in carb (nothing mentioned in instructions), but been doing that with motorcycles for decades.

Haven't had it long but like it so far.

Work horse generator at a better price than Honda, November 14, 2011 By Ethosian (Earthquake Zone, California)

This generator has seen lots of use since I bought it, charging the batteries on our RV, and powering up the AC lighting and refrigerator circuits simultaneously. We've used it to run portable equipment (electric chain saw and hedge trimmers) when city power wasn't available. I love the thing. It's nice and quiet. Not powerful enough for the microwave on full power or the air conditioner, but it runs everything else just fine. If I go camping in the desert in summer I'll by another one so you can chain them together to power the air conditioner. No complaints.

I ordered my Yamaha EF2000iS generator on Sunday evening. It shipped on Monday and arrived at my door on Wednesday!! I put oil and gas in it and it fired up on the very first pull. I have only had it a couple of hours so I haven't had a lot of time to test it out, but this thing seems to be just great. It is not very loud at all, especially when it is under a light load. I would highly recommend this generator and I am sure I will get years of service out of it.
