Yamaha EF2200iS vs Honda EU2200i: A Comparison

When it comes to choosing the perfect portable generator, two brands consistently stand out in the market: Yamaha and Honda. Known for their reliability, performance, and innovative technology, both Yamaha’s EF2200iS and Honda’s EU2200i are excellent choices for powering outdoor activities, job sites, or emergency backup. These two generators offer similar power output, but their unique features, design, and performance set them apart. In this review, we’ll compare the Yamaha EF2200iS and Honda EU2200i to help you make an informed decision on which one is the best fit for your needs.

1. YAMAHA EF2200iS Inverter Generator

The Yamaha EF2200iS Inverter Generator is a reliable and portable power solution, particularly for outdoor activities like camping or RV trips. Powered by a robust 79cc Yamaha engine, it delivers 2200 watts of power, providing sufficient capacity for most small appliances, lights, and even some power tools. One of the standout features of this model is its exceptional quiet operation, thanks to Yamaha’s Quiet Technology, which ensures noise levels stay between 57-65 dBA—low enough that you could easily converse while it’s running. The Smart Throttle function is another highlight, adjusting engine speed based on load to optimize fuel efficiency and reduce noise further. This generator is also well-equipped with convenient features like a user-friendly Smart Dial for easy starting, an illuminated LED display, and a fuel gauge for real-time monitoring.

Despite its many advantages, the EF2200iS does have a few drawbacks. While its portability is enhanced by the tri-handle design, it weighs a hefty 55.2 pounds, making it slightly cumbersome for one person to transport over long distances. Additionally, some users have reported that the noise levels are not as low as advertised, particularly when the generator is under heavier load. Furthermore, while it offers solid runtime, with up to 10.5 hours of operation on a quarter load, those looking for even longer run times may need to refuel more frequently. Lastly, while it includes an RV outlet, it’s still crucial to confirm compatibility with your RV’s power requirements before use.
