The EF2000iS has been updated, improved and is now even cheaper, which makes it an excellent value. For all the details, read our comprehensive review of the UPDATED model — Yamaha EF2000iSv2.
The Yamaha EF2000iS is an exceptional inverter generator for anybody who requires power on the go or for anybody who wants to be prepared in case of an emergency or disaster. The Yamaha EF2000iS is capable of powering your microwave oven, a camping fridge, power tools or a TV. Whatever you need, wherever you are, this well-designed inverter generator will make your life so much easier.
NOTE: The Yamaha EF2000iS has been improved and the new model number is EF2000iSV2. It’s basically the same generator with some internal circuitry improvements. All the information in the article is still relevant. This is the difference as explained by Yamaha:
The EF2000iSv2 incorporates a completely new controller with advanced programming resulting in improved output characteristics between 1600w-2000w operation ranges. The addition of the new programming allows the EF2000iSv2 the ability to power a much wider range of applications than previous generation EF2000iS.
*All links take you to the EF2000iSV2. You can no longer purchase the original model. Again, Yamaha has just updated the model but it looks exactly the same and shares the same features.

The Yamaha EF2000iS is Actually Quiet
Yamaha has designed the EF2000iS to be super quiet at under 58dBA (decibels). For a reference point, a normal conversation is about 60dBA. One of the biggest complaints people have with their portable generator is how loud they are, which is understandable because the noise can drive you a little crazy. Thankfully, the Yamaha EF2000iS is very quiet thanks to its noise block body design which includes a molded casing with noise-absorbing glass wool. That’s their secret sauce.
It’s power rating is: AC output = 1,600 watts (13.3 amps) up to 2000 watt maximum AC output.
Yes, you can actually have a conversation while Yamaha EF2000iS is running in the background. There’s really no excuse for having a loud inverter generator nowadays. Sure, you can buy a cheaper generator but I guarantee you that it will be annoyingly noisy. What’s the price of your sanity worth? That’s a question that only you can answer.
Fortunately, this Yamaha inverter generator has a lot of excellent features beyond just being whisper quiet.
Special Camouflage Design | Yamaha EF2000iS
It’s ultra portable with its suitcase style extra-large handles — and it only weighs 46 lbs when full of fuel. So, not only is easy to carry but it’s also compact and can be conveniently placed in the trunk of your car or the back of your SUV if you like to go camping or fishing.
Another great thing about the Yamaha EF2000iS is that it’s ready to use in parallel with another EF2000iS for extra power when you need it, such as running multiple appliances in a motor-home.
Yamaha is a leader when it comes to portable inverter generators as they have ‘pulse width modulation’ technology that creates pure sine-wave voltage, which means, it produces clean energy that won’t damage your electronic equipment, high-tech appliances or power tools. This is an important factor to consider when buying an inverter generator. There’s no point in buying a cheap power generator and then have it damage your equipment.
The Yamaha EF2000iS is built with many smart features that make your life easier, such as something Yamaha calls Smart Throttle which automatically changes the engine speed to coincide with the electrical demands so that it runs efficiently and preserves fuel enabling it to run longer before you need to refuel it.
Also, another smart feature is that it has an electrical overload breaker to protect the internal circuits in case of a power overload. And, if that wasn’t enough, the Yamaha EF2000iS has an oil warning system that shuts off the generator if the oil is low and it won’t allow you to turn it back on until you add oil to it. This is a very well designed inverter generator, and worth every penny.
Another important use for a portable generator is that it allows you to have access to power in case of a disaster or emergency. There’s no shortage of possible scenarios that may require your reliance on an inverter generator, but on any given day anything can happen, and when the power goes out you’ll wish you had a generator to make your life easier. Even something as simple as powering your lights in the middle of the night and keeping your phone charged becomes a nightmare when you’re cut off from all power sources.
This Yamaha EF2000iS has many uses and that’s the beauty of this particular product — it’s versatile and can adapt to your changing needs and conditions. Here are some great applications for this product:
- Power tools and lights on a construction Site.
- Protect yourself in case of a natural disaster.
- Keep your refrigerator running in case of a power outage.
- Keep your sump pump running to prevent flooding.
- Camping, fishing and other recreational activities.
- Extra portable power for your RV.
Overall the Yamaha EF2000iS is one of the best portable inverter generators that you can buy. It’s not the cheapest generator you can buy but it’s easily one of the best. It’s well engineered and designed for portability and maximum power. It’s very easy to carry around and transport while providing excellent smart features that protect your investment while providing power wherever you need it.
