Description
Zoom on the Yamaha EF2800i
In summary, the Yamaha EF2800i is a compact and lightweight portable inverter generator especially useful for:
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
- Handcrafting enthusiasts who wish to work on-the-go
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals who want to ensure that a power failure will not prevent them from working
- RV travellers looking for even more independence
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
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.
Enjoying a noise rating of 65 dBA (just slightly more noisy than a normal conversation), this inverter generator gets running thanks to a conventional 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).
Sensitive electronics can be safely plugged in the AC outlets, as the EF2800i produces a clean sine wave, with a <2.5% Total Harmonic Distortion (THD).
Outlets
The control panel features the upcoming 3 AC outlets:
It also sports 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 a conventional, open frame design, of the following dimensions: L19.2 x W15.6 x H16.7 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
The EF2800i's dry weight of 68 lbs lets you use its power anywhere needed. Moreover, its open frame design makes it incredibly easy to grab the frame in order to change its location.
Features
Several light indicators serve to show you when the generator is overloaded, the generator is ready and the oil level is too low.
The inverter generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Watch system), allowing you to 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, making it usable 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).
- As far as its dry weight is concerned, the Yamaha EF2800i weighs just 68 pounds and thus, it is one of the lighter 2000 to 3000 rated wattage inverter generators. If you are concerned by weight, one of the champions in the above-mentioned power range is the Westinghouse iGen2500, with a dry weight of just 46.3 pounds.
- 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 one of your priorities, you may be interested in the Honda EU3000iS, one of the least noisy generators similarly powerful as this one, rated for 50 dBA.
- The EF2800i provides a higher run time than similarly powerful inverters, reaching up to 14.7 hours at 25% load. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EU3000iS, which is able to run for 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. This inverter generator has an estimated fuel consumption of roughly 0.18 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 Cummins Onan P2500i, which boasts with a gas consumption of only 0.1 GPH, may be the right generator for you.
The bottom line
- GFCI Outlets
- Inverter
- Lightweight (68 lbs)
- High run time
- Decent fuel efficiency
- No data center
- No electric start
- No parallel ports
- Not CARB-compliant
- On the noisy side (65 dBA)
