Description

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 a nutshell, the Yamaha EF2200iS is a quiet, compact and lightweight portable inverter generator mostly geared towards:

  • Camping and tailgating buffs looking to enhance their experience
  • DIYers who wish to improve their efficiency with tools
  • RV travellers wishing to enhance their freedom and nomad lifestyle

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

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 1800W and reaches a peak wattage of 2200W. 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.

The inverter generator is rated for a noise of 57 dBA (less noisy than a refrigerator). Its starting mechanism is based on 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.

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

The EF2200iS produces a clean sine wave: thanks to a <2.5% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel provides the upcoming 3 AC outlets:

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

In addition, it provides 1 DC outlet: there's a 12V 3A (cigarette lighter style) receptacle with which you may charge your batteries with ease.

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

Portability

As the Yamaha EF2200iS is an inverter generator, its encased design (L21.9 x W11.8 x H18.5 in) offers more aesthetics than a conventional, open frame product. This type of design is the most modern and convenient way to recreationally generate power.

With a dry weight of 55.2 lbs, the EF2200iS can easily follow you wherever your power needs are. Furthermore, moving the EF2200iS from A to B is made easier thanks to its convenient triple handle (molded in the case), which vastly improves your grip.

Features

Panel of the Yamaha EF2200iS

The EF2200iS's control panel

The control panel of the EF2200iS includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the power output.

In addition to this info, the device’s light indicators will display if the generator is overloaded and its oil levels are insufficient.

The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Accessory-wise, along with the previously mentioned features, the Yamaha EF2200iS is packaged with the standard documentation and an owner's manual (opens in a new tab), helping you start the device right away.

Emissions

The Yamaha EF2200iS is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all 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 generators of similar power (between 1500 and 2500 W).

  • Having a dry weight of 55.2 lbs, the Yamaha EF2200iS belongs in the expected weight range for generators which produce 1500 to 2500 rated watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Champion 200949, with a dry weight of just 38.6 pounds.
  • Since the inverter generator's noise is rated at 57 dBA, it has the roughly average expected noise for a device of similar power. If noise emissions are one of your priorities, you may be interested in the Honda EU2200i, one of the least noisy generators similarly powerful as this one, rated for 48 dBA.
  • As the EF2200iS offers up to 10.5 hours run time on a full tank at a 25% load, it falls within the average autonomy range among the generators of a similar power. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse WGen2000, which is able to run for up to 26 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. Standing at an estimated 0.12 GPH (gallon per hour) at a 25% load, this inverter generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.08 GPH, the Predator 2000 is a device you could look out for.

Here's a list of the most popular specific comparisons:

Price comparison

As you can see from this interactive chart, when compared to other 1500-2500W 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.
