To start, the most impressive features of the EU3000iS is how quiet it is. Producing a maximum volume of just 57 dB, this generator makes as much noise as many competing 2,000-watt generators do when running without any power load. On top of that, it can run for a massive 7.4 hours at its rated load on a single tank of gas – or up to 20 hours at 25% load. The generator is built around a genuine Honda engine, which virtually guarantees that this generator will last for decades if properly maintained. With those features in mind, it’s easy to see why Honda can charge a premium for this generator – and why users rave about the machine after putting it to use.

Honda Power Equipment EU3000IS

The Honda EU3000iS is also called as the one of the best 3,000-watt inverter generators, capable of producing 3,000 watts of surge power and 2,800 watts of continuous power. This power availability makes the generator incredibly versatile. 3,000 watts is just enough power to run all of your home’s essential appliances and a few rooms’ worth of lights during a power outage. Alternatively, 3,000 watts can allow you to turn on everything, including an air conditioning unit, inside a medium to large RV.


  • Power for furnace, fridge, most 13,500 BTU RV AC units, & more
  • Super quiet & fuel efficient
  • Electric start
  • Inverter – stable power for computers & more
  • CO-MINDER: advanced carbon monoxide detection system

Ease of use

With the exception of the lack of USB ports described above, Honda did place emphasis on ease of use in designing the EU3000iS. The generator comes with an electric starter and the battery is built into the generator, charging automatically when the generator is turned on, so that you never need to fuss with it. In case the battery ever does die or there’s a problem with the electric start, there’s also a recoil starter available on the generator. The recoil starter is simple and users report that it fires the generator up within one to two pulls every time.


Add more power with parallel capability

Need more power? Add a second EU3000iS for additional power. Two identical models can be paralleled with an optional cable.

Excellent source of power for RVs, including 13,500 BTU AC units

This popular model can operate a wide variety of appliances, including a furnace, fridge, microwave, most 13,500 BTU RV AC units, and much more. Take a look at the applications tab for more examples.

Super quiet - less noise than normal conversation

So quiet, your neighbors will thank you. The EU3000iS operates at 50 to 57 dB(A), which is less noise than a normal conversation. This makes it ideal for camping, RV power and any other activity that requires quiet operation.

Fuel efficient - Runs nearly 20 hours on 3.4 gal of fuel

Thanks to our exclusive Eco Throttle System, the EU3000iS offers great fuel efficiency. Runs from 6.9 to 19.6 hours on a single tank, depending on the load. This makes it great for overnight power.
