The innovative inverter system produces high-quality, clean electricity. View larger.
The EF1000iS 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.
Smart Technologies for Optimal Fuel Efficiency
The EF1000iS is exceptionally fuel efficient, able to run for up to 12 hours without refueling when in Economy mode. 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
At only 27.6 pounds, this generator is also 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. For added convenience, the EF1000iS is even able to recharge 12-volt batteries with its 12-volt DC output, making it ideal for RV, auto, and boat owners.
Noise Reduction for Quiet Operation
The EF1000iS uses noise reduction technologies to ensure the quietest operation possible. Featuring a special sound-blocking design, the generator has a noise-absorbing glass wool construction, which helps dampen noise even during heavy operation. Along with the EF1000iS' super-quiet muffler, it helps keep noise to a minimum.
The EF1000iS is backed by a two-year warranty.

My big plusses:
1 - REALLY quiet. The engine drives basically just an alternator and produces about 12V, though it varries. When there is a small load on the generator (typical of most camping / outdoor uses) it slows down the engine. This not only makes it quiet, it cuts back on fumes, and saves gas. A tank filling can last half a day easily depending on demand.
2 - clean power. Because the alternator is outputting a DC voltage into a sinewave inverter your 110 VAC is comming from one of the best sources. I use inverters in many of my service vehicles, right at 1000W, and have found no situation where that was not enough power. Since the inverter tells the throttle how much power it needs, wasted noise and gas are eliminated. Basically it does not feel like the old 5000W genset on wheels.
3 - light weight. Compared to taking the 5000W generator camping, the small size and light weight are a welcome change.
4 - very small gasoline consumption. Unless you are running the full 1000W all the time you'll get great mileage. If you do need to run 1000W all the time, consider a larger digital inverter genset. Honda makes a 2000W which can be joined to a second 2000W for 4000 total if I recall.
5 - well built engine. Although only 50cc, it has overhead valves and excellent sound isolation.
It's not going to run EVERYTHING in your RV at the same time. If you are watching the plasma TV (400W) and turn on the microwave (1000W) the generator will shut down due to the 1400W load.Read more ›
It is extremely quiet, just slightly louder than that of a good refridgerator.
Why the 4-star rating?
The Yamaha website doesn't appear to be too up-to-date on Yamaha Generator Service Shops. When we got our generator, it had a bad seal on it and the oil leaked out. When we looked on the Yamaha website, it showed two dealers in our area that fixed these generators. Neither one would take it. They said they stopped working on generators. I ended up having to drive over to the next town where the dealer told me that most dealers do not like to take generators unless they sold it to you themselves.
So, while I got lucky and found someone that would take it. Just be aware that you might not be so lucky. Before buying, call the dealers on the Yamaha website and ask them if they can fix a generator for you. Then you will have a better idea of what situation you are in before you buy.
