A portable generator can be a lifesaver when the power goes out or in outdoor settings where electricity is unreachable. However, choosing one can be tricky: you want the right size, something that isn’t noisy, and something that fits your budget. That’s why we’re here comparing two popular models: the Honda EU10is and the Honda EU22is.
Performance & Power
Running Power (W)
The running power of a generator determines what appliances or tools you can use with it. The EU10is has 900 watts of running power, enough to maybe supply a small air conditioning unit (750W) or a power hand drill (700W). On the other hand, the EU22is provides higher running power at 1800 watts, able to sustain more demanding appliances like a space heater (1500W) or electric grill (1650W).
Starting Power (W)
The starting power indicates peak wattage for initial bursts needed by some devices. Here, the EU10is offers 1000W and the EU22is provides a considerably higher 2200W. If you’re powering tools that need high startup energy like larger air conditioners or big saws, the EU22is would be preferable.
Both models utilise an OHV engine, promoting longer lifespan and better fuel efficiency. The main difference lies in size: the compact EU10is has a 49.4cc engine while the EU22is employs a more substantial 121cc engine, contributing to its greater power output.
Rated Output (kVA)
Apparent power – measured in kVA – combines real and reactive powers. For our generators, the rated output naturally follows their wattage differences: 0.9 kVA for the EU10is and twice as much at 1.8 kVA for the EU22is. If you have equipment demanding higher current, consider the EU22is.
Both models feature inverter technology, generating clean power for your sensitive gadgets, like laptops. This tech also tends to give you quieter, more fuel-efficient generators.
Fuel & Run Time
Both models operate on petrol.
Fuel Tank Capacity
Here lies a difference: the EU10is has a 2.1L fuel tank, while the EU22is boasts a larger 3.6L tank. This means fewer refills on the EU22is but potentially heavier lift on your end.
Interestingly, at 1/4 load, the smaller EU10is can last slightly longer – 3.2 hours as opposed to the EU22is’ 3 hours. Although marginal, this could factor in if runtime is crucial in your decision.
The lightweight EU10is weighs 13kg while the more potent EU22is comes in at 21.1kg – a factor to consider if mobility is important to you.
When it comes to size, both are compact with minimal difference; the EU10is measures 45.1 x 24.2 x 37.9 cm while the slightly bigger EU22is measures 50.9 x 29 x 42.5 cm.
Unfortunately, neither model includes wheels which might affect portability if you have to haul it across distances frequently.
Outlets & Parallel Use
The Honda EU10i provides one AC outlet while the Honda EU22i doubles that with two AC outlets allowing you to plugging multiple devices at once.
Each model features one DC outlet useful for charging batteries or powering small appliances like mobile phones or laptops.
The ability to connect two identical generators for enhanced power is available on both models, being incredibly useful if you ever find yourself needing more power.
Features & Usability
Each model boasts an effortless recoil starter system and a smart oil alert system that signals when oil is low, among other similar usability features. Regrettably, they seem to lack certain aspects like fuel gauges and a variety of identifiable special indicators.
Lastly, let’s talk about noise level. The compact EU10i is calmingly quiet at just 52dB, while the more powerful EU22i jumps up to around 89dB. To put things in perspective, the quiet hum of a refrigerator operates at around 55dB but city traffic could climb to about 85dB.

In conclusion, the Honda EU10is could be recommended for someone after a quieter, lighter device with marginally longer run time and doesn’t mind lesser strength. However, if your priority leans towards more power output and bigger fuel capacity or you require multiple AC outlets, you might lean towards the Honda EU22is instead. Your choice ultimately hinges on your individual need.
