Description
Zoom on the Yamaha EF2800i
In summary, the Yamaha EF2800i is a compact and lightweight portable inverter generator especially useful for:
- Camping and tailgating buffs looking to enhance their experience
- Handcrafting enthusiasts who wish to work on-the-go
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals who want to ensure that a power failure will not prevent them from working
- 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 EF2800i
The Yamaha EF2800i houses a 171 cc (5.5 hp) Yamaha MZ175 OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 2500W along with a peak wattage of 2800W.
The inverter generator features a conventional pull-start mechanism. It is rated for a noise of 65 dBA (just slightly more noisy than background music).
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 EF2800i can operate for up to 14.7 hours with a full tank (fuel consumption around 0.18 GPH), due to its fuel capacity of 2.6 gallons.
The EF2800i 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 provides the upcoming 3 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 10A receptacle with which you may charge your batteries with ease.
While this Yamaha generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.
Portability
The dimensions of the Yamaha EF2800i, which are L19.2 x W15.6 x H16.7 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.
As the EF2800i's weight is only 68 lbs, it can follow you and your power needs anywhere. Furthermore, the open frame of the generator further helps when holding and moving it to a different place.
Features
The EF2800i's control panel
Several light indicators serve to show you when the generator is ready, the oil level is too low and the generator is on overload.
The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
As for its security measures, the device features an automatic low oil shut-off (Oil Watch system) and an overload protection (circuit breaker), letting you use it with a peace of mind.
Yamaha's Oil Watch warning system gives you an extra peace of mind. This feature enhances long-term durability by preventing engine damage and costly repairs. Once the oil begins to run low, the generator automatically shuts off and cannot be re-started until oil is added.
Regarding its accessories, besides the aforementioned features, the Yamaha EF2800i'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 EF2800i is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor and therefore, can be used in forested areas.

The Yamaha EF2800i versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Yamaha EF2800i compare to generators of similar power (between 2000 and 3000 W).
- Weight-wise, the Yamaha EF2800i has only 68 lbs, which renders it one of the lighter generators which produce 2000 to 3000 rated watts. In terms of weight, one of the champions in their power range is the Westinghouse iGen2600, standing at just 48 lbs.
- Among the generators of a comparable running wattage, this inverter generator with a lowest noise of 65 dBA can be judged as noisy. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU3000iS with only 50 dBA.
- The EF2800i, offering a run time of up to 14.7 hours with a full tank at a 25% load, falls within the average autonomy range when compared to its peers. 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.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. This inverter generator has an average fuel consumption among comparably powerful devices, as it reaches 0.18 GPH (gallon per hour) at a 25% load. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen2600, which boasts with a gas consumption of only 0.1 GPH, may be the right generator for you.
Price comparison
As you can see from this interactive chart, when compared to other 2000-3000W generators, the Yamaha EF2800i is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
