Zoom on the Yamaha EF2400iSHC
In summary, the Yamaha EF2400iSHC is a quiet and compact portable inverter generator especially useful for:
- Camping and tailgating buffs looking to enhance their experience
- Amateur DIY lovers
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 EF2400iSHC
The Yamaha EF2400iSHC's design includes a gasoline-fueled 171 cc Yamaha MZ175 OHV 4-stroke engine. With a 120V output, it gives a running wattage of 2,000W and also a peak wattage of 2,400W.
Enjoying a noise rating of 53 dBA (just slightly more noisy than a refrigerator), this inverter generator gets running thanks to 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 1.6 gallon, the EF2400iSHC may run for up to 11 hours with a full tank (fuel consumption around 0.15 GPH).
As the EF2400iSHC 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 includes the following 2 AC outlets:
It also sports 1 DC outlet: there's a 12V 8A receptacle with which charging your batteries is made easy.
Portability
The Yamaha EF2400iSHC is an inverter generator and has an encased design of the following dimensions: L20.8 x W16.5 x H18.2 in. Thus, it is more aesthetical than conventional, open frame products. The generator has a contemporary design, convenient for recreationally generating power.
The 75 lbs of the EF2400iSHC's dry weight enables you to use it anywhere you will ever need. In addition, its nifty double handle improves your grip, allowing for an easy transport of the EF2400iSHC from place to place.
Features
The EF2400iSHC's control panel
Several light indicators serve to show you when the generator is overloaded, its oil levels are insufficient and the generator is ready.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Watch system), letting you 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.
Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Yamaha also included a battery charging cables in the EF2400iSHC's packaging.
Emissions
The Yamaha EF2400iSHC is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
Moreover, it features a spark arrestor, so it is adequate for use in forested areas.

The Yamaha EF2400iSHC versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Yamaha EF2400iSHC compare to inverter generators of similar power (between 1500 and 2500 W).
- With its weight of 75 lbs, the Yamaha EF2400iSHC is one of the heavier inverter generators in the 1500-2500 rated wattage category. In terms of weight, one of the champions in their power range is the Genmax GM2000i, standing at just 34.2 lbs.
- With a lowest noise rating of 53 dBA, the inverter generator is one of the more quiet of the generators of similar type and power. 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 EU2200i, whose lowest noise levels reach just 48 dBA.
- Thanks to an impressive running time of up to 11 hours at 25% load, the EF2400iSHC benefits from a higher run time than many inverter generators of a similar output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Yamaha EF2800i, boasting with up to 14.7 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. In fact, this inverter generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 25% load is around 0.15 GPH. If fuel consumption is your top priority, we suggest to check out the DuroMax XP2300iH, which has a fuel consumption of only 0.08 GPH and thus, is one of the most efficient devices in our database.
The bottom line
- Inverter
- Quiet for its power (53 dBA)
- High run time
- Made in Japan
- No data center
- No electric start
- No parallel ports
- On the heavy side (75 lbs)
- Low fuel efficiency
