HIGH POWER MEETS BOLD FEATURES. Offers high power output, sophisticated quiet technology, rich features and rugged design. (source: Yamaha (opens in a new tab))

Zoom on the Yamaha EF2200iS

In summary, the Yamaha EF2200iS is a quiet, compact and lightweight portable inverter generator especially useful for:

  • Camping and tailgating hobbyists looking for a portable power source
  • Amateur DIY lovers
  • RV travellers who wish to upgrade their experience to another level

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Yamaha EF2200iS in use

The Yamaha EF2200iS

The Yamaha EF2200iS's engine, 79 cc Yamaha MZ80 OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 1,800W and reaches a peak wattage of 2,200W. In addition, the device is parallel capable (Twin Tech cable (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.

Enjoying a noise rating of 57 dBA (less noisy than a quiet suburb), this inverter generator gets running thanks to a simple traditional pull-start mechanism.

This generator features Yamaha's Smart Throttle™. This load-sensing feature automatically adjusts engine speed to match its load in order to offer greater fuel efficiency and noise reduction.

The fuel capacity of 1.24 gallon allows the EF2200iS to operate for up to 10.5 hours with a full tank (fuel consumption around 0.12 GPH).

Delicate electronics can be plugged in an AC outlets safely, as the EF2200iS generates a clean sine wave, reaching a <2.5% Total Harmonic Distortion (THD).

Outlets

The control panel includes the following 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

Furthermore, it has 1 DC outlet: there's a 12V 3A (cigarette lighter style) receptacle allowing you to easily charge your batteries.

This Yamaha generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

Since the Yamaha EF2200iS is an inverter generator, its closed design (L21.9 x W11.8 x H18.5 in) has an esthetical advantage over conventional, open frame devices. This modern design aims to provide an ideal power solution to recreational users.

The EF2200iS's dry weight of 55.2 lbs lets you use its power anywhere needed. Moreover, shifting it is an easy task, as the EF2200iS features a nifty triple handle (molded in the case), improving your grip greatly.

Features

Panel of the Yamaha EF2200iS

The EF2200iS's control panel

To help you monitor the EF2200iS's status and activity, its control panel is equipped with a digital data center, giving you information on the power output.

In addition to this info, some light indicators allow you to instantly see if the generator is overloaded and its oil levels are insufficient.

The inverter generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.

Along with the aforementioned features, from an accessory standpoint, the Yamaha EF2200iS's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.

Emissions

The Yamaha EF2200iS is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, so it is adequate for use in forested areas.

The Yamaha EF2200iS versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Yamaha EF2200iS compare to inverter generators of similar power (between 1500 and 2500 W).

  • At a dry weight of 55.2 pounds, the Yamaha EF2200iS is one of the heavier inverters which can produce between 1500 and 2500 running watts. Regarding dry weight, one of the champions in the same power range is the Genmax GM2000i, with a dry weight of only 34.2 lbs.
  • When compared to devices able to produce a similar running wattage, this inverter generator and its lowest emitted noise of 57 dBA is on the noisier side. For those who are looking for a less noisy device, we suggest the Honda EU2200i. With just 48 dBA, it is one of the most quiet devices in this power range.
  • Given that the EF2200iS reaches an autonomy of up to 10.5 hours with a full tank and at 25% load, it is placed within the average autonomy range of similarly powerful inverter generators. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the DuroMax XP2300iH, with up to 13 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This inverter generator has an average fuel consumption among comparably powerful devices, as it reaches 0.12 GPH (gallon per hour) at a 25% load. If fuel consumption is your top priority, we suggest to check out the DuroMax XP2300iH, which has a fuel consumption of only 0.08 GPH and thus, is one of the most efficient devices in our database.
According to our stats, the following comparison is pretty popular: Yamaha EF2200iS vs Honda EU2200i.

Price comparison

As you can see from these interactive charts, when compared to other 1500-2500W inverter generators, the Yamaha EF2200iS is on the expensive side of the price range.

While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
