- RV travellers looking for even more independence
In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.
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.
With a noise rating of 65 dBA (just slightly more noisy than background music), the inverter generator's starting mechanism is centered around 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.
The EF2800i's fuel tank, boasting 2.6 gallons, allows it to operate for up to 14.7 hours with a full tank (with an estimated fuel consumption of 0.18 GPH).
As the EF2800i produces a clean sine wave, with a <2.5% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.
Outlets
The control panel features the following 3 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 10A receptacle providing easy battery charging capabilities.
While not classified as 'RV Ready,' this Yamaha generator can still provides the advantage of RV connection via its L5-30R receptacle, ensuring power supply to your RV with an L5-30P to TT-30R adaptor.
Portability
At L19.2 x W15.6 x H16.7 in, the standard open frame design of the Yamaha EF2800i delivers stability alongside easy maintenance access to components and good air cooling. The featured design is ideal for the outdoors and all tough environments.
As the EF2800i's weight is only 68 lbs, it can follow you and your power needs anywhere. Furthermore, thanks to its open frame, the generator is easily grabbed and moved to a new location.
Features
The EF2800i's control panel
The light indicators show you if the generator is ready, the generator is overloaded and the oil level is too low.
Featuring a built-in fuel gauge, the inverter generator offers quick, convenient, and easy gas level checks at a glance.
Security-wise, this product benefits from an automatic low oil shut-off (Oil Watch system) and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
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.

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).
- Having a dry weight of 68 lbs, the Yamaha EF2800i belongs in the expected weight range for inverter generators which produce 2000 to 3000 rated watts. If weight is a key factor for your needs, the WEN 56280iX is noteworthy for being one of the top contenders in this power range, with a dry weight of 41.9 pounds.
- As this inverter generator has its lowest possible noise of 65 dBA, it should be considered noisier compared to its peers of a comparable running wattage. For those who are looking for a less noisy device, we suggest the Honda EU3000iS. With just 50 dBA, it is one of the most quiet devices in this power range.
- With up to 14.7 hours of runtime at 25% load, the EF2800i provides a higher run time when compared to similarly powerful inverters. 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.
- 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. When it comes to fuel efficiency among generators with similar wattage, this inverter generator lags behind, with a consumption rate of 0.18 GPH at a 25% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen2800. With a fuel consumption of as little as 0.08 GPH, it is one of the most efficient generators currently on the market.
The bottom line
- GFCI Outlets
- Inverter
- High run time
- Decent weight (68 lbs)
- No data center
- No electric start
- No parallel ports
- On the noisy side (65 dBA)
- Low fuel efficiency
