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
  • Handcrafting enthusiasts who wish to work on-the-go
  • RV travellers wishing to enhance their freedom and nomad lifestyle

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's design includes a gasoline-fueled 79 cc Yamaha MZ80 OHV 4-stroke engine. With a 120V output, it gives a running wattage of 1,800W and also a peak wattage of 2,200W. Additionally, as the generator is parallel capable (Twin Tech cable (opens in a new tab) not included), it can be linked to a second unit for more power.

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

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 fuel capacity of 1.24 gallon, the EF2200iS may run 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 Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel includes the following 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 allowing you to easily charge your batteries.

This Yamaha generator is RV Ready, as it features a 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. The design follows the contemporary trends and is perfect for recreationally generating power.

With a dry weight of 55.2 lbs, the EF2200iS can easily follow you wherever your power needs are. 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

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, several light indicators serve to show you when its oil levels are insufficient and the generator is overloaded.

Thanks to a built-in fuel gauge, the inverter generator allows you to quickly, conveniently and easily check the gas level at a glance.

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.

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

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 inverter generators of similar power (between 1500 and 2500 W).

  • With its weight of 55.2 lbs, the Yamaha EF2200iS is one of the heavier inverter generators in the 1500-2500 rated wattage category. 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.
  • This inverter generator, with its lowest possible noise rated at 57 dBA falls into the more noisy category, compared to other devices of a similar running wattage. If you are concerned with noise, check out the Honda EU2200i, which is one of the least noisy generators in its power range, with a noise rating of just 48 dBA.
  • The EF2200iS, offering a run time of up to 10.5 hours with a full tank at a 25% load, falls within the average autonomy range when compared to its peers. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the DuroMax XP2300iH, which is able to run for 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 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 DuroMax XP2300iH. With a fuel consumption of as little as 0.08 GPH, it is one of the most efficient generators currently on the market.
