Description
Zoom on the Yamaha EF2800i
In a nutshell, the Yamaha EF2800i is a compact and lightweight portable inverter generator mostly geared towards:
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
- DIYers who wish to improve their efficiency with tools
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals who want to be able to deliver results, even during a power failure
- RV travellers looking for even more independence
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 EF2800i
The Yamaha EF2800i's engine, 171 cc (5.5 hp) Yamaha MZ175 OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 2,500W and reaches a peak wattage of 2,800W.
The inverter generator is rated for a noise of 65 dBA (just slightly more noisy than a normal conversation). Its starting mechanism is based on a simple traditional pull-start mechanism.
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 2.6 gallons, the EF2800i may run for up to 14.7 hours with a full tank (fuel consumption around 0.18 GPH).
The EF2800i 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 features the upcoming 3 AC outlets:
Additionally, it features 1 DC outlet: there's a 12V 10A receptacle with which charging your batteries is made easy.
Even if this Yamaha generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle.
Portability
The Yamaha EF2800i has the following dimensions: L19.2 x W15.6 x H16.7 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.
The EF2800i can be taken anywhere with you, thanks to its weight of 68 lbs. Moreover, grabbing and moving this product is made even easier by its open frame design.
Features
The EF2800i's control panel
Some light indicators allow you to instantly see if the generator is on overload, the generator is ready and its oil levels are insufficient.
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 far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off (Oil Watch system) and an overload protection (circuit breaker).
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.
As for its accessories, apart from the previously mentioned features, the Yamaha EF2800i also comes with the basic documentation and an owner's manual (opens in a new tab), allowing you to start it right away.
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 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 you are concerned with noise, check out the Honda EU3000iS, which is one of the least noisy generators in its power range, with a noise rating of just 50 dBA.
- Thanks to an impressive running time of up to 14.7 hours at 25% load, the EF2800i benefits from a higher run time than many inverter generators of a similar output. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Honda EU3000iS, with up to 20 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. Standing at an estimated 0.18 GPH (gallon per hour) at a 25% load, this inverter generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If fuel consumption is your top priority, we suggest to check out the Cummins Onan P2500i, which has a fuel consumption of only 0.1 GPH and thus, is one of the most efficient devices in our database.
The bottom line
