Compact and ergonomic, the EF2000iS is easy to store and transport. View larger.
TwinTech technology allows you to hook up two units for added output. View larger.
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
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
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.
What's in the Box
The EF2000iS has the EPA's longest engine emission life rating. View larger.
The EF2000iS recharges 12-volt batteries, making it ideal for boat, RV, and auto owners. View larger.

The most impressive thing about this unit is how quiet it is. Even at full engine speed you can stand about 6 feet away and have a normal conversation without raising your voice, or talk on a cell phone without undue distraction. It features an "eco" setting which tapers down the engine throttle and noise when full load isn't required. At half-throttle or less, from about 6 feet away it is about half as loud and amazingly quiet. I used it to run a 50-amp 12v battery charger and at full charge level the charger only required the generator to operate at about half-speed, and when the charger tapered down the charge level to under 30-amps the generator became so quiet I literally forgot about it. It is MUCH quieter than my boat's inboard diesel engine, and more efficient than running the main engine just to top off the batteries. I also used it to power a heavy duty 120v grinder and it had no problems supplying the needed power, even on electric motor start-up.Read more ›
Edit: I've had two EFYamaha 2000is generators since the beginning of Sept, 2010 and have mainly used them for camping. The first workout for both of these units was tailgating. I also have a cord that connects the 2 of them to make 4000 watts, more than enough to power your camper A/C (13,000-15,000btu) and everything else in the RV. However, it was colder on this outing and I didn't need to use both hooked together yet. I did bring both of them though and I'm glad I did- here's why:
The guy next to me brought his 6000watt Champion generator, which is construction grade, and told me he was sorry, but would be running it in the mornings. We were about 15 feet away from him. I said no problem, it couldn't be that loud. He then turned it on for me so I could see. WOW! That thing was LOUD. I told him I brought a spare Yamaha inverter and he was welcome to use mine because I told him it would be much quieter. He came over and heard mine running and couldn't believe it. The next morning we were both sleeping soundly, both of us running these awesome Yamaha units.
Here are some tips for those considering this generator:
1) Get some fuel stabilizer.Read more ›
It easily powers drills, grinders, skill saws, table saws, sawzalls, and portable cement mixers - pretty much anything that draws under 16.7 Amps. Most power tools draw up to and under 15 Amps. My industrial right-angle concrete drill only draws 8 Amps, and that thing is rugged. It's more than enough for my needs for working in the woods where I can't just "Plug In."
Another thing that's slick about it is it also charges marine batteries and has its own special DC receptical and comes with the included cable. You just fire it up, hook up the terminals to your battery, then plug in the cord. It doesn't have a charge meter built in, so I purchased a hand held battery tester and check the charge level once an hour. I think the battery tester was under $30 (a good investment).
With that in mind, I used it last Memorial Day weekend during our Men's Family Fishing Trip out at Johnston Pond camp here in Maine, out in the woods roughing it with tents. The area is surrounded with small-ish ponds, so my dad and I brought our little skiff and trolling motor with us (too small ponds for our larger, 2-stroke boat). We brought two 12 volt marine batteries with us to make sure we could spend the whole day out each day, then that evening charge one or the other up so it was ready for the next day. It worked great, we didn't have to worry about running our batteries low and having to paddle all the way back to the landing.Read more ›
