  • Professionals who want to be able to deliver results, even during a power failure
  • RV travellers looking for even more independence

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 in use

The Yamaha EF2800i

The Yamaha EF2800i's core is the 171 cc (5.5 hp) Yamaha MZ175 OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 2,500W and a peak wattage of 2,800W.

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 fuel capacity of 2.6 gallons allows the EF2800i to operate for up to 14.7 hours with a full tank (fuel consumption around 0.18 GPH).

Delicate electronics can be plugged in an AC outlets safely, as the EF2800i generates a clean sine wave, reaching a <2.5% Total Harmonic Distortion (THD).

Outlets

The control panel includes the following 3 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle

It also sports 1 DC outlet: there's a 12V 10A receptacle allowing you to easily charge your batteries.

Even though this Yamaha generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor.

Portability

The design of the Yamaha EF2800i is a typical, open frame, with the dimensions of L19.2 x W15.6 x H16.7 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough environments and demanding outdoor use.

With a dry weight of 68 lbs, the EF2800i can easily follow you wherever your power needs are. In addition, it is even easier to grab and move the generator around thanks to its open frame design.

Features

Panel of the Yamaha EF2800i

The EF2800i's control panel

When the generator is ready, its oil levels are insufficient and the generator is on overload, you will be informed by the featured light indicators.

The inverter generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

From a security point of view, the generator is equipped with an automatic low oil shut-off (Oil Watch system) and an overload protection (circuit breaker), giving you a peace of mind during use.

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.

Along with the aforementioned features, from an accessory standpoint, the Yamaha EF2800i's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.

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, which makes it suitable for use 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 inverter generators of similar power (between 2000 and 3000 W).

  • In terms of its dry weight, the Yamaha EF2800i stands at only 68 lbs, meaning that is one of the lighter inverters of the 2000-3000 rated wattage category If weight matters to you, one of the champions in this power range is the WEN 56360i with only 46.3 pounds.
  • This inverter generator, with its lowest possible noise rated at 65 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 EU3000iS with only 50 dBA.
  • As the EF2800i features an autonomy of up to 14.7 hours at 25% load, it has a higher run time than an average generator of its type and power range. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EU3000iS, boasting with up to 20 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Cummins Onan P2500i. With a fuel consumption of as little as 0.1 GPH, it is one of the most efficient generators currently on the market.
According to our stats, the following comparison is pretty popular: Yamaha EF2800i vs Honda EG2800i.
