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.

Honda EU3000is : 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.
