Description
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
- Amateur DIY lovers
- RV travellers who wish to upgrade their experience to another level
In the sections ahead, the power characteristics, availability of various outlets, the portability and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Yamaha EF2200iS's core is the 79 cc Yamaha MZ80 OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 1800W and a peak wattage of 2200W. Moreover, since it is parallel capable (Twin Tech cable not included), its power may be doubled if linked to a second compatible unit.
The inverter generator features a simple traditional pull-start mechanism. It is rated for a noise of 57 dBA (less noisy than a quiet suburb).
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.
Sensitive electronics can be safely plugged in the AC outlets, as the EF2200iS produces a clean sine wave, with a <2.5% Total Harmonic Disruption (THD).
- For camping/tailgating: 1 DVD player, 1 slow cooker, 1 satelite receiver, 1 mixer, 1 game console, 1 radio and 1 cell phone charger
- At home: 1 DVD player, 1 slow cooker, 1 satelite receiver, 1 mixer, 1 security system, 1 set of 5 LED light bulbs and 1 fan
- For work: 1 electric fence (25 miles), 1 drain cleaner and 1 bug zapper
Outlets
The control panel provides the upcoming 3 AC outlets:
Furthermore, it has 1 DC outlet: there's a 12V 3A receptacle allowing you to easily charge your batteries.
With its TT-30R receptacle (TT as in '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 esthetics than a conventional, open frame product. The generator has a contemporary design, convenient for recreationally generating power.
The 55.2 lbs of the EF2200iS's dry weight enables you to use it anywhere you will ever need. In addition, its nifty triple handle (molded in the case) improves your grip, allowing for an easy displacement of the EF2200iS from place to place.
Features
The EF2200iS's control panel
When the generator is overloaded and the oil level is too low, you will be informed by the featured light indicators.
Thanks to a built-in fuel gauge, the inverter generator allows you to quickly, conveniently and easily check the gas level at a glance.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.
Besides the features previously mentioned, accessory-wise, the Yamaha EF2200iS comes with the usual documentation and user manual needed to get you promptly started.
Emissions
The Yamaha EF2200iS is neither EPA approved nor CARB-compliant..
However, it features a spark arrestor and thus, may be used in forested areas.
Product Video
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).
- At a weight of 55.2 pounds, the Yamaha EF2200iS places in the expected weight range of the generators in the 1500-2500 rated wattage range. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN 56202i, with a dry weight of just 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 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, falls within the average autonomy range compared to generators of a roughly same power, with a run time of 10.5 hours at a 25% load and a full tank. 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 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 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 you wish to further improve in the area of fuel efficiency, the Energizer eZV2000P, which boasts with a gas consumption of only 0.08 GPH, may be the right generator for you.
Here's a list of the most popular specific comparisons:
Price comparison
As you can see from this dynamic 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.
The bottom line

- Parallel capable
- Inverter
- Decent weight (55.2 lbs)
- Acceptable noise (57 dBA)
- Decent run time
- Decent fuel efficiency
- On the expensive side
- No data center
- No electric start
- No EPA or CARB compliance
