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 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
  • Handcrafting enthusiasts who wish to work on-the-go
  • 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 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.

The inverter generator features a conventional pull-start mechanism. It is rated for a noise of 57 dBA (less noisy than rainfall).

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

The EF2200iS generates a clean sine wave: providing <2.5% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

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.

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Yamaha generator is RV Ready.

Portability

Thanks to its closed inverter generator design (L21.9 x W11.8 x H18.5 in), the Yamaha EF2200iS, is more esthetical than a typical, open frame generator. The generator has a contemporary design, convenient for recreationally generating power.

The EF2200iS's dry weight of 55.2 lbs lets you use its power anywhere needed. In addition, its nifty triple handle (molded in the case) improves your grip, allowing for an easy transport of the EF2200iS from place to place.

Features

Panel of the Yamaha EF2200iS

The EF2200iS's control panel

The light indicators show you if the oil level is too low and the generator is overloaded.

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 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.

Besides the features previously mentioned, accessory-wise, the Yamaha EF2200iS comes with the usual documentation and owner's manual needed to get you promptly started.

Emissions

The Yamaha EF2200iS is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 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. If weight matters to you, one of the champions in this power range is the Champion 200949 with only 38.6 pounds.
  • As this inverter generator can emit noise as low as 57 dBA, it finds itself in the average expected noise for this kind of power. 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.
  • The EF2200iS, falls within the average autonomy range compared to generators of a roughly same power, with a run time of up to 10.5 hours at a 25% load and a full tank. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse WGen2000, as it provides up to 26 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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 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.
