Here are the benefits of the Yamaha EF2000iS:
- The size and weight of the Yamaha EF2000iS makes it a very portable generator that is easy to carry around your house, garden, camping site or onto your car,boat or RV. It weighs only 44.lbs which makes it light enough for anyone to handle.

What are people saying about the Yamaha EF2000iS?
Here are reviews from people using the Yamaha EF2000iS:
Awesome Quiet Little Inverter-Generator!
I purchased the Yamaha EF2000iS generator for extended fishing trips, for charging 12 volt marine batteries and for running corded power tools in remote areas. It easily powers drills, grinders, skill saws, table saws, sawzalls, and portable cement mixers – pretty much anything that draws under 16.7 Amps. Another thing that’s slick about it is it also charges marine batteries and has its own special DC receptacle and comes with the included cable. This unit really is quiet. On a recent fishing trip everyone did nothing but praise how quiet it was, unlike our neighbors who had an old style generator and had to holler at each other in order to talk. On top of all that goodness, since it’s an inverter as well, you can also safely power computers, charge cell phones and iPods, run a TV and DVD player, and plenty of other things. I give the Yamaha EF2000iS five stars hands down for the price and performance. If you need a medium duty inverter generator, I highly recommend it. You will enjoy it.

Buy this first
Like most people shopping for a generator I let price dictate my purchase. I bought a cheap generator from one of the big box stores, ran it for 1 season and then it crapped out just out of warranty. I was a complete noob and thought electricity was electricity. Then I discovered you need clean power if you are going to run sensitive devices like TV’s and Computers. I did my homework this time and bought the Yamaha EF2000iS. It’s worth every penny, it’s light weight, produces clean power and out performs the cheapos hands down. You don’t save money on the cheapos if it doesn’t start next season. No amount of maintenance or storage tactics makes up for poor quality.

Excellent small inverter generator
I bought the Yamaha EF2000iS to power some radio equipment and small household appliances during emergencies. The unit arrived from Amazon in excellent condition. The generator started on the very first pull after adding oil and gas. Subsequently it starts on every pull or second pull. It runs amazingly quiet. You can put this unit outside a door and basically not hear it. The engine runs smooth and clean, and the unit is well built. Light enough to carry a reasonable distance. This Yamaha generator is good and efficient . I wouldn’t hesitate to buy it again.

Here are the disadvantages of the Yamaha EF2000iS:
- The unit may be more expensive than other brands of inverter generators but satisfied buyers felt the price was well worth the quality they bought, compared to cheaper generators that break down and don’t last as long as the Yamaha EF2000iS
- You do need to be careful to add your own oil into the EF2000iS engine before you start using it because it doesn’t come packed with any oil.
