Honda EU22i Review and How It Compares to Other Portable Generators
The Honda EU22i is widely regarded as one of the most reliable portable inverter generators available. It suits a broad range of uses from powering a caravan on a remote pitch to keeping essentials running during a power cut, or providing clean, stable electricity on a work site and it has built that reputation by consistently delivering where lesser machines fall short.
In this Honda EU22i review, we’ll take a closer look at its performance, fuel efficiency, portability and key features. We’ll also compare it with some of its main competitors to help you decide if it is the right generator for your needs.
Honda EU22i Specifications and Performance
At the heart of the Honda EU22i is Honda’s commercial-grade GXR120 engine. This 121cc four-stroke engine is renowned for its durability, smooth operation and long service life, making it a popular choice for both leisure and professional users.
The EU22i delivers:
- Maximum output: 2,200 watts
- Rated continuous output: 1,800 watts
The maximum output provides the extra power needed to start appliances with electric motors, while the rated output keeps equipment running efficiently once started.
As an inverter generator, the EU22i produces a pure sine wave output. This provides clean, stable electricity that is suitable for sensitive electronics such as laptops, smartphones, televisions, drones and medical equipment including CPAP machines.
Lightweight and Easy to Transport
Weighing just over 21kg, the Honda EU22i remains one of the most portable generators in its class. The compact design and integrated carry handle make it easy to move, load into a vehicle and store when not in use.
This combination of portability and performance has made it particularly popular with caravan owners, campers, tradespeople and event operators who need reliable power away from mains electricity.
Fuel Efficiency and Honda Eco Throttle
One of the standout features of the Honda EU22i is its impressive fuel economy.
Honda’s Eco Throttle system automatically adjusts engine speed to match the electrical load being used. Rather than running at full speed continuously, the generator only works as hard as necessary.
For example:
- Charging a laptop or running low-power devices causes the engine to idle quietly.
- Higher-demand appliances automatically trigger increased engine speed.
This intelligent system reduces fuel consumption, lowers noise levels and helps extend engine life.
With its 3.6-litre fuel tank, the EU22i can typically run for between 3.2 and 8.1 hours depending on the load being applied.
Quiet Operation
Noise levels are often a major consideration when choosing a portable generator.
Honda has engineered the EU22i with advanced sound insulation and a specially designed exhaust system, resulting in exceptionally quiet performance.
Noise levels are approximately:
- 53 dB(A) at 25% load
- 70 dB(A) at full load
For comparison, 53 dB(A) is quieter than a typical conversation, making the EU22i an excellent choice for campsites, outdoor events and residential use.
Honda EU22i vs Honda EU20i
The Honda EU20i was one of the most popular portable generators ever produced, but the EU22i introduced several important improvements.
Key differences include:
- More Power
The EU22i provides 2,200W maximum output compared with 2,000W from the EU20i.
- Larger Engine
The EU22i uses the newer 121cc GXR120 engine, replacing the older 100cc engine found in the EU20i.
- Improved Maintenance
Honda redesigned the oil filler opening, making routine servicing cleaner and easier.
- Fuel Shut-Off Valve
The addition of a fuel shut-off valve allows the carburettor to run dry before storage, helping prevent fuel-related issues.
Honda EU22i vs Yamaha EF2200iS
The Yamaha EF2200iS is one of the EU22i’s closest competitors.
Both generators offer:
- 2,200W maximum output
- 1,800W continuous output
- Inverter technology
- Excellent fuel efficiency
- Quiet operation
The Yamaha includes a convenient Smart Dial system and illuminated control panel.
However, many users prefer the Honda’s slightly lighter weight, compact dimensions and proven GXR120 engine. Honda’s Eco Throttle system is also widely regarded as particularly responsive when dealing with changing electrical loads.
Both are excellent generators, but the Honda EU22i continues to set the benchmark for reliability and long-term ownership.
Parallel Operation
If your power requirements increase in the future, you do not necessarily need to purchase a larger generator.
Two Honda EU22i generators can be connected using Honda’s approved parallel connection kit, providing:
- 4,400W maximum output
- 3,600W continuous output
This gives users the flexibility of portable generators while providing significantly more available power when required.
