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 hobbyists looking for a portable power source
  • Amateur DIY lovers
  • 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. In addition, as it is parallel capable (Twin Tech cable (opens in a new tab) not included), this power can be doubled when linked to another similar or compatible unit.

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.

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 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 features 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 with which charging your batteries is made easy.

This Yamaha generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The Yamaha EF2200iS is an inverter generator and has an encased design of the following dimensions: L21.9 x W11.8 x H18.5 in. Thus, it is more aesthetical than conventional, open frame products. The featured design follows the latest trends and is ideal for easy and recreational use.

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

A digital data center, one of the features of the EF2200iS's control panel, gives you information on the power output, and thus, is helpful for the monitoring of its activity and status.

In addition to this info, several light indicators serve to show you when the generator is overloaded and the oil level is too low.

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

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to 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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Besides the features previously mentioned, accessory-wise, the Yamaha EF2200iS comes with the usual documentation and owner's manual (opens in a new tab) needed to get you promptly started.

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 and therefore, can be used 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. If weight is your top priority, one of the champions in this power category is the Genmax GM2000i, weighing just 34.2 pounds.
  • 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 noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU2200i with only 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. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the DuroMax XP2300iH, as it provides up to 13 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider 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 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.

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 inverter generators, the Yamaha EF2200iS is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
