Generator Review: Honda EU22i vs Honda EU20i

Generator Review: Honda EU22i vs Honda EU20i
Rate this post

Honda just added a new generator to its line-up: the Honda EU22i. Here’s how it compares to the legacy model Honda EU20i.

If you’re planning to upgrade your generator, or are in the market for something new, Honda has just made the decision even harder with its new Honda EU22i.

So, what’s new? Here, we compare it to the ever-popular Honda EU20i to see how they match up:


Physically, both the Honda EU22i and EU20i appear to be the same size.  But look closer and there are significant differences. The Honda EU22i actually has a larger 4-Stroke GXR120 engine for a maximum output of 2200 watts. That’s 10% more power than the EU20i – enough for an extra bar fridge.

By comparison, the Honda EU20i uses Honda’s 4-stroke GX100 engine for a maximum power output of 2,000 watts and rated output of 1,600 watts.

The Parallel Connection is a favourite feature of the Honda generators, so you’ll be happy to hear that they haven’t done away with it for the Honda EU22i. You can still use a cable to link two EU22i models and double your output.

Fuel economy

Both generator models have a built-in Eco Throttle which adjusts the engine speed to meet the load demand. As a bonus, this feature also reduces generator noise, as the engine doesn’t run at full capacity unless needed.

This means, with a 4-litre fuel tank, the Honda EU22i can run for up to 8 hours continuously if the Eco-Throttle is switched on at 1/4 output.

Start-up power

At 2200 watts, the Honda EU22i has a higher start up output than its predecessor – great if you need to start up power-hungry caravan air-con units.


No changes here. Both the Honda EU22i and the EU20i feature a microcomputer-controlled sinewave inverter. This guarantees commercial-quality electricity, so you can confidently use the generator to power frequency sensitive electrical equipment, such as computers.


When it comes to portable generators, Honda knows how to pack maximum power into compact machines. By using their own high-speed multi-point alternator integrated into the engine, Honda reduces the overall weight and size by as much as 50% compared to similarly classed models. As a result, despite the extra features on the new model, both the Honda EU20i and EU22i weigh in at 21kg.


Honda has added a few handy details to the new design, which make the EU22i more user friendly. The Honda EU22i features a vented cap which is a different colour to the rest of the unit. This small detail makes it easier to remember to vent the cap to the “on” position when you’re running the generator.

It also has special “run dry switch” that lets you run the generator out of fuel before you put your Honda EU22i into storage for a while.

In both models, the engine is protected via low oil alert system. But the new Honda EU22i has a larger oil filler for improved draining and catching of oil.

Another handy detail in the Honda EU22i, which is lacking on the EU20i, is the metal reinforcement around the recoil starter handle. This is designed so that even the most heavy-handed users won’t damage the unit when pulling the cord.


The Honda EU20i has held the crown of the world’s best-selling leisure generator, and it’s easy to see why. But with the smart user-friendly design and extra 10% power, the Honda EU22i will definitely give it a run for its money.

The Honda EU22i is a great generator but is up there in price. Alternatively checkout the Cromtech outback 2400w inverter generator.
