First of All, Inverter Generators!

Inverter generators, such as the Yamaha EF2200iS, are a remarkable advancement in portable power generation. With the EF2200iS as an example, these generators feature innovative technology that ensures stable and clean electricity output, making them highly sought after for a variety of applications.

Moreover, the Yamaha EF2200iS inverter generator, like other models in its class, operates with reduced noise levels. This feature is achieved through sound-dampening technologies and thoughtful design, making it ideal for environments where noise reduction is a priority, such as camping grounds or residential areas.

Enhanced Yamaha Engine Performance and Power!

The EF2200iS inverter generator by Yamaha is outstanding in its own way and features the company’s MZ80 four-stroke single-cylinder engine with a displacement of 79cc. For user convenience and easiness, the engine is equipped with an on-off switch, mechanical choke, and a recoil “pull” starter. With a remarkable 1.24-gallon gas tank, a 1/4-load of Yamaha assures that the EF2200iS can operate continuously for over 10 hours.

However, the inclusion of a larger engine and fuel tank makes this generator’s weight heavier, which amounts to 55 pounds. But seeing this downfall the Yamaha has thoughtfully integrated three sizable carry handles into the design of the case, making it easier to move around and carry from one place to another.

Yamaha EF2200iS Features

The EF2200iS Generator boasts a compact design, making it easily transportable to any location. Its robust 79cc OHV engine delivers an impressive 2200-watt maximum output, providing ample power to run essential appliances, electronics, and tools.

Let’s discuss the features in detail.


The EF2200iS is powered by a Yamaha 79cc MZ80 four-stroke single-cylinder engine. This engine provides reliable performance and is known for its quiet operation.


The generator features two standard 120-volt 15-amp three-prong power outlets, providing convenient power access for various devices. Additionally, it includes a 120-volt 30-amp RV outlet, making it an excellent choice for RV owners.


Output Indicator

The front control panel of the EF2200iS has an LED output indicator that displays the generator’s power output. It also includes overload and low-oil indicators, providing warnings when necessary.

Yamaha Smart Throttle

The Smart Throttle feature adjusts the generator’s idle speed based on the power load. When the power load is low, the generator lowers its idle speed, reducing noise output and conserving fuel. When more power is demanded, the generator automatically throttles up to meet the requirements.

CO Sensor and Ground Lug

For safety, the EF2200iS is equipped with a CO sensor that detects high levels of carbon monoxide buildup. If triggered, the engine shuts off, preventing potential harm. The generator also features a ground lug on the front panel, allowing it to be properly grounded for additional protection against electric shock.

Twin Tech Parallel Capability

With the use of the Yamaha Twin Tech parallel kit (sold separately), you can link two EF2200iS generators together. This feature allows for increased power output, providing up to 30 amps of power and nearly double the wattage. It is especially useful for powering high-demand devices like RV air conditioning units.

Control Panel and User Features

The generator’s control panel includes useful features such as an easy-to-read gas gauge, an easy drain function for removing fuel from the carburettor, and a single dial for run and stop functions.

Control Panel and User Features

It also has LED illumination, a digital load meter for monitoring power usage, a low oil indicator, a 30-amp RV outlet, two standard 120V household outlets with overload protection, and a 12V DC battery charging outlet. The main “Power Boost” breaker allows for resetting the generator after an overload situation without shutting it down.


The Yamaha and Honda generators provide customers with a generous 4-year limited warranty, backed by networks of spare parts and by extensive service.


When models Honda and Yamaha manufactured by top companies surely come at a higher price point. However, this price reflects the superior innovation and reliability associated with these renowned brands. The Yamaha generator has a suggested retail price (RRP) of $2299, while the Honda generator is priced at $2099 RRP.

  • Yamaha Smart Throttle feature ensures lower noise output and fuel consumption by adjusting engine speed to match the load.
  • CO sensor keeps carbon monoxide levels in check and shuts off the engine if heavy buildup is detected.
  • With two standard 120-volt 15-amp outlets, a 12-volt receptacle, and a 120-volt 30-amp RV outlet, it has a versatile array of outputs.
  • Can be linked with another EF2200iS generator using the Twin Tech parallel cable to increase power output.
  • The run time may not be as long as other generators, with up to 10.5 hours at 25% load and even less at 50% load.
  • Has a manual choke and recoil starter instead of an automatic choke and electric starter which can be an inconvenience.
