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 EU3000iS 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.

Appliances Galore

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.

Honda EU3000iS : Super Quiet

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. 

This generator is ideal for Camping, RV parks,  Home Power Backup and any situation that requires quiet power generation.

Fuel Efficient and more

This little monster can run for up to 20 hours on a single tank of gas (3.4 gallon of fuel in one tank load).  The Generator uses Honda's patented Eco Throttle System to give you fabulous fuel economy.

It is great at running your RV AC overnight as well. At constant full power you get at least 7.2 hours of operating time before you need a refill.

A very convenient and efficient electric starting option relieves the physical stress of getting the generator started.

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

Clean power

The Honda EU3000iS produces clean and pure sine wave output thanks to advanced electronics in its inbuilt inverter. The  power output is clean like your wall AC outlet.

Thus, you get clean and reliable power for all equipment including sensitive electronics like computers, audio equipment, medical equipment and so on. 

Daisy Chain the Honda EU3000iS

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

IMPORTANT : You can only daisy chain a EU3000is with another EU3000is.

In addition to the clean AC power that the generator produces, it also outputs DC power at 12 volts (upto 12 amps).

You will need an optional charging cord if you plan to use use the DC output to charge your Auto Batteries. 

EU3000iS Controls

The control panel is easy access and well labelled.  Turn the Engine start switch to START to electric start the Honda EU3000is.

Once the generator is running, turn the switch back to the ON position. Close the Choke button while starting the generator cold, and return back to open position after the generator starts.

The DC 12V output is only for AUTO Battery Charging - don't use it for any DC devices. It outputs a maximum of 12 Amps at 12 volts.

The 3 AC outputs are all at 120 volts. There are 2 regular 120 Volt, 20 Amp outlets and a single lockable 120 volt, 30 amp socket.

The Eco Throttle mode is great while using low power loads. The generator runs at a lower engine rpm reducing noise and fuel consumption. 

Honda Warranty

Other safety features  include an Engine Shut off feature when it runs low on Oil.  All important circuitry is protected from overloads and power spikes and the Spark Arrestor / Muffler is USDA certified.
