Thanks to its innovative inverter system, the generator is able to generate up to 1,000 watts of clean AC power. It can run up to 12 hours continuously without refueling and uses premium technologies to maximize fuel efficiency.
EF1000iS InverterAt a Glance
- Combines powerful output with portability
- Inverter system allows you to power delicate machinery
- Fuel-efficient; can run for 12 hours without refueling
- Lightweight and easy to carry
- Backed by a 2-year warranty
The innovative inverter system produces high-quality, clean electricity. .Powerful Inverter System Delivers Cleaner ElectricityThe 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 EfficiencyThe 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 DesignAt 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 OperationThe 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.

Customer Reviews
I've used these with friends camping and been absolutely amazed. This model has a number of positives about it. Yamaha has produced small, reliable generators for over 15 years.
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.
Cons:
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. Consider your loads and if you must run everything simultaneously.
Heavy loads make it spin faster and thus change the acoustic tone of the exhaust. If it's within hearing range and you turn alot of stuff on/off the noise may irritate some people.
Pros:
Put a 100 foot extension cord between you and the generator and you'll be saying "what generator" as the lights and appliances work fine for 12+ hours. It's that quiet.
1000W is enough to run your vehicle's battery charger, a good size TV, and small cooking appliances, just not at the same time. Consider the kill-a-watt wattmeter to know EXACTLY what your load is P3 International P4460 Kill A Watt EZ Electricity Usage Monitor
I wanted a smaller generator than the one built into my RV to save on gas and operate quieter. this little yamaha did the trick. I use a 50 foot extension cord and run it to my rv through the window. It can power my computer, battery chargers, and small appliances on its quiet, low power setting. I barely hear when it is running on low power if it is 50 feet from the RV. Uses only 1/2 gallon of gas if i run it all day. but you do need to go to a local Yamaha dealer and get the proper oil. make sure you read the instructions for this or you will burn out the motor.
