Honda EU20i Generator Details

Delivering 2000 watts of portable power, the Honda EU20i generator is the ultimate leisure generator for the more demanding user. This tough and compact unit is powerful enough for all kinds of tasks where you don’t have access to the mains whether you’re abroad in the caravan or motor home, working at the end of the garden, entertaining outdoors or even to provide emergency back-up when there’s the inevitable power cut. Honda’s exclusive Inverter technology gives you unsurpassed power stability to run even the latest high tech electronics safely through the twin 230V outlets. And although the EU20i has enough capacity to power a microwave oven or several appliances simultaneously, its unique Eco Throttle means the EU20 is frugal too.

At the flick of a switch this feature only runs the engine as fast as the load demands, enabling the EU20i to run for over ten hours on a single tank of fuel (1/4 load) , with minimal noise and fuel cost and maximum engine life.

Power is passed through a special microprocessor which "smooths" the power output so computers and other sensitive electrical equipment can be run safely on this model. EU20i generator features Eco Throttle, this offers excellent fuel economy by incorporating a load-dependent speed control governor which automatically adjusts engine speed to the optimal level.

The low noise design only produces 52db@ 7m, equivalent to the noise level in a typical business office. Parallel cables are available as an extra to allow the EU20i generator to be connected to other portable EU20i's to provide additional power.


  • 2000 watts max output 
  • Noise Output: 52dB(a) at 7m @ 1/4 load
  • Lightweight at only 21kg 
  • Running Time 10.5hours @ 1/4 load
  • 5 Years Warranty
  • Inverter technology
  • Stylish and ergonomic design
  • 12 volt DC output
  • Optional Parallel Cable for linking 2 Generators to double the power output

The low noise output of the Honda EU10i & 20i makes them ideal for caravan use.

As per Honda's recommendation we are Honda Dealers and will ensure that your new Honda EU20i is started & tested ( PDI ) before dispatch. A Honda Trained Engineer will remove your new generator from the box and start & test. This gives you the confidence that you should not experience any problems when receiving your order or just as important any failure to comply with Honda's warranty conditions.

Quality comes at a price, but well worth it. - Review by Paul Davey

I've been looking for a generator for some time that would give me a pure and clean portable electrical supply, and there is nothing out there that comes close to the Honda range. I'm an electrical engineer by trade and would recommend this product all the time. The service and customer support that Just Generators provide complement the Honda product. (Posted on 31/05/2017)

This generator is perfect for use on our boat to charge batteries, heat the water and power our electronic devices. Its very quite and portable for the size of generator and starts first time.
Great service from Just Generators, helpful advice before purchasing and then efficient service from order to delivery. (Posted on 11/05/2017)

A solid, quiet generator that starts easily and provides a nice steady flow of electrons when and where needed.
As others have mentioned, the oil filler is a tad awkward, but nothing a funnel and a steady hand can't deal with.

Good service from Just Generators too. (Posted on 24/04/2017)

Not had this very long, but very pleased so far. Very quiet, seems to regulate perfectly (with the loads I have used so far), normal Honda build quality. Starts easily too.
Filling it with oil is a little fiddly, the oil filler is low down and a little recessed, but that is my only adverse comment. And of course, quality doesn't come cheap.
Excellent service from Just Generators.
