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
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.

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 a major difference, the way humans perceive it.

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.

I got this mainly for charging our boat's batteries at anchor but I also wanted the ability to run power tools. The lighter 1000-watt inverter generators could easily handle the charging application but not the more power-hungry tools. Having the extra power also means the eco-throttle will likely kick in earlier and the unit will operate quieter. The number-1 purchase criteria was "quiet" because I don't want to be distracted by incessant noise or be a bad neighbor in anchorages. The Honeywell was not quiet enough in my opinion.

If generators are abused it will lead to regulations banning them, so an appeal to other boaters and to campers: Please don't settle for "cheap". Get a better quality inverter-generator unit that's quieter so you minimize noise pollution in get-away places. (Leave your "contractors generator" at home!!!) Also, please be considerate of neighbors and limit running it to times/places you aren't as likely to disturb others... and don't leave your boat or campsite while it runs and runs. We all like our electric conveniences, but if you really need 120v power more or less constantly you should either stay home or get a dock/parking space where you can plug into "the grid". It's rude to disturb others who are trying to get away to find some peace and quiet.

Negative: The unit ships without engine oil, so you need to buy a quart of standard 4-stroke engine oil and fill it. You will also need a funnel, and a pan to catch excess oil. There is no dipstick; you need to fill to the level of the bottom of the filler hole until any more runs out. It uses less than 3/4 quart. I think they should have included the required amount of oil, and a plastic filler container with a spout, marked to show the proper amount of oil to use.
