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:

  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go
  • DIYers who wish to improve their efficiency with tools
  • RV travellers who wish to upgrade their experience to another level

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Yamaha EF2200iS in use

The Yamaha EF2200iS

The Yamaha EF2200iS houses a 79 cc Yamaha MZ80 OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 1800W along with a peak wattage of 2200W. Moreover, since it is parallel capable (Twin Tech cable (opens in a new tab) not included), its power may be doubled if linked to a second compatible unit.

At a noise rating of 57 dBA (less noisy than a conversation at home), the inverter generator is started via 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.

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

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

Outlets

The control panel features the upcoming 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 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. The design follows the contemporary trends and is perfect for recreationally generating power.

The EF2200iS can be taken anywhere with you, thanks to its weight of 55.2 lbs. 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

Some light indicators allow you to instantly see if its oil levels are insufficient and the generator is overloaded.

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

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

Regarding its accessories, besides the aforementioned features, the Yamaha EF2200iS's box includes the typical documentation and an owner's manual, letting you start it right off the bat.

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, making it usable 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).

  • As its weight is 55.2 pounds, the Yamaha EF2200iS falls in the expected weight range of the devices in the 1500-2500 rated wattage category. In terms of weight, one of the champions in their power range is the Champion 200949, standing at just 38.6 lbs.
  • This inverter generator has a somewhat average expected noise for its power range, rated at 57 dBA. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU2200i, whose lowest noise levels reach just 48 dBA.
  • 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 generators. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Westinghouse WGen2000, reaching 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. This inverter generator has an estimated fuel consumption of roughly 0.12 GPH (gallon per hour) at a 25% load, rendering it somewhat average compared to devices of a similar output. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Predator 2000. With a fuel consumption of as little as 0.08 GPH, it is one of the most efficient generators currently on the market.

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.
