Why makes the EU3000iS a winner ?

SMALL : The small Honda EU3000iS Portable Generator is a powerful 3000 watt Portable Generator.  But, the biggest asset of the Generator are its looks, its small footprint and its muted operational noise. All of which makes its so different from its cousin Portable Generators. 

Even though this Portable Generator is not the most powerful in its class, its power to weight ratio and silent operation makes the Honda EU3000iS a formidable Portable Generator.

If 3000 watts of power is not enough, you might be interested in the more powerful Portable Generator  featured in this article. And for those who are interested in a completely noiseless generator,  a Solar Generator might be a better choice. Continue to read on for more.

PLUG & PLAY : The EU3000iS is a plug and play portable generator that is easy to use with a broad selection of AC outputs and can even charge your car batteries.  

Real Customer Reviews

John Thorley of San Diego : " I now have 2  of these generators. They are awesome little machines. My first unit is 3 years old and still going really strong.

Love the quiet operation plus they really are fuel efficient, use very little gas. I added all terrain wheels to grab them for easy moving and now they are light enough for me to move alone. "

Dolph R, NJ : " I have nine of these babies and I use them constantly to run movies. The Honda EU300iS is very best generator in its class.  

I run each of them for hours and hours on end and they take it without a complaint.  All they need is a little care, Change their oil weekly and use 100% synthetic oil and thats it, you will get thousands of hours from this beauty.

Something to look out for - when the transporter delivers them they sometimes come loaded sideways or upside down and some oil leaks out into the paper air filter.

Soon this causes the unit to belch smoke and run very rough.  Best to check the oil filter, watch some Youtube videos and of course read the manuals. Next, add oil and gas and start your new Honda EU3000IS".

Delaney T, MA :  This is the quietest generator I have had...  and its my fourth.  Everything is as Honda promised.

The only problem is that the unit is heavy : it is about 150 lbs once you have topped up gas and oil.  I got wheels now and its pretty easy getting it up and running in about 10 minutes.

The unit has a front plate that needs to be removed and then the battery has to be connected. Only then will the electric start work. All good things come at a cost, so this unit is expensive, but it is money well spent.

One of the most popular Honda generators, this unit can power a broad range of appliances including a Fridge, Freezer, a Furnace, most microwaves and AC units rated 13,500 BTU or lower.

It generates 2800 watts of continuous power for hours on end producing 23.3 amps of current. It is equipped to provide a surge output of 3000 watts at 25 amps of current and thus is able to give the required surge to get the AC compressor started.

One of the major attractions of the Honda EU3000iS is its Super quiet operation. Its noise level is between 50 to 57 dB(A).

That is actually less noise than a regular conversation.  As a silent generator your Honda EU3000iS will never cause your neighbor or fellow RV camper to complain about generator noise.

The very convenient and efficient electric starting option that relieves the stress of getting the generator started.

Honda also included an easy recoil starting option as a back up, in case the electric start fails.

The Honda EU3000iS can be daisy chained i.e. you can connect it in parallel with another unit to have twice the power output.
