Description
Zoom on the Yamaha EF2800i
In a few words, the Yamaha EF2800i is a compact and lightweight portable inverter generator perfectly suited for:
- Camping and tailgating hobbyists looking for a portable power source
- 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 be able to deliver results, even during a power failure
- RV travellers wishing to enhance their freedom and nomad lifestyle
Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.
Power & Run Time
The Yamaha EF2800i
The Yamaha EF2800i is powered by a 171 cc (5.5 hp) Yamaha MZ175 OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 2,500W as well as a peak wattage of 2,800W.
With a noise rating of 65 dBA (just slightly more noisy than an office), the inverter generator's starting mechanism is centered around a manual recoil starter system.
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).
The <2.5% Total Harmonic Distortion (THD) of the EF2800i ensures a clean sine wave output, providing a secure power source for your sensitive electronics through its 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.
This Yamaha generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.
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 generator is designed for ideal use outdoors and in rough environments.
With a dry weight of 68 lbs, the EF2800i can easily follow you wherever your power needs are. Furthermore, thanks to its open frame, the generator is easily grabbed and moved to a new location.
Features
The EF2800i's control panel
Light indicators on the device will notify you if the generator is overloaded, the oil level is too low and the generator is ready.
The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Watch system), 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.

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).
- At a weight of 68 pounds, the Yamaha EF2800i places in the expected weight range of the inverter generators in the 2000-3000 rated wattage range. If you are mindful of weight, the WEN 56280iX is among the top contenders in this power range, with a dry weight of 41.9 pounds.
- This inverter generator, with its lowest noise level at 65 dBA, is noisier than most generators of comparable running wattage. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU3000iS, whose lowest noise levels reach just 50 dBA.
- Among its inverters with similar power, the EF2800i offers one of the higher run times, running for up to 14.7 hours at 25% load. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EU3000iS, reaching up to 20 hours.
- Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. This inverter generator is somewhat less fuel-efficient than devices of comparable output: its estimated fuel consumption reaches 0.18 GPH at a 25% load. To prioritize fuel savings, we advise considering the Westinghouse iGen2800c, which stands out for its gasoline efficiency, consuming just 0.08 gallons per hour.
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
