How Loud Does It Run?

Anyone who’s familiar with these machines will know that they can be pretty loud. In fact, at times they can even irritate some people. That’s why there are campsites out there that have outright banned loud generators from being used by campers. 

Luckily for those of you who plan on using this generator on a camping trip or if you live in a quiet suburb, this generator is not loud. From about 20-feet out, it has a noise rating of 78db. 

This is not quiet by any means, but it is only slightly louder than normal conversation volume. While it won’t run as smoothly as generators designed to run quietly, it will definitely be running at a volume that just about anyone in the area can tolerate with no problem.

How Durable Is It?

As is expected from a large and powerful machine such as this one, there have been a couple of measures put in to make sure it will last for a long time. For starters, the overall build quality of the generator is sturdy, which is part of the reason the machine weighs what it does. 

Aside from that, it has multiple coats of anti-corrosive material, which can reduce the damage that time can do to the generator and help it keep working and serving its purpose for years to come.

Powerful Inverter System Delivers Cleaner Electricity

The 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.

This means you can use it to run sensitive appliances like computers, charge phones, Camera equipment and laptops.

Smart Technologies for Optimal Fuel Efficiency

The EF1000iS is exceptionally fuel-efficient, able to run for up to 10-12 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 Design

At 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 Operation

The 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.
