Description
Zoom on the Yamaha EF2400iSHC
In summary, the Yamaha EF2400iSHC is a quiet and compact portable inverter generator especially useful for:
- Camping and tailgating hobbyists looking for a portable power source
- Handcrafting enthusiasts who wish to work on-the-go
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.
Power & Run Time
The Yamaha EF2400iSHC
The Yamaha EF2400iSHC's engine, 171 cc Yamaha MZ175 OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 2,000W and reaches a peak wattage of 2,400W.
The inverter generator is rated for a noise of 53 dBA (just slightly more noisy than rainfall). Its starting mechanism is based on 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.
The EF2400iSHC can operate for up to 11 hours with a full tank (fuel consumption around 0.15 GPH), due to its fuel capacity of 1.6 gallon.
Delicate electronics can be plugged in an AC outlets safely, as the EF2400iSHC generates a clean sine wave, reaching a <2.5% Total Harmonic Distortion (THD).
Outlets
The control panel features the upcoming 2 AC outlets:
Additionally, it features 1 DC outlet: there's a 12V 8A receptacle with which charging your batteries is made easy.
Portability
Since the Yamaha EF2400iSHC is an inverter generator, its closed design (L20.8 x W16.5 x H18.2 in) has an esthetical advantage over conventional, open frame devices. The featured design follows the latest trends and is ideal for easy and recreational use.
As the EF2400iSHC's weight is only 75 lbs, it can follow you and your power needs anywhere. Moreover, shifting it is an easy task, as the EF2400iSHC features a nifty double handle, improving your grip greatly.
Features
The EF2400iSHC's control panel
Some light indicators allow you to instantly see if the oil level is too low, the generator is ready and the generator is overloaded.
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.
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.
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. Therefore, its sale and purchase are permitted in all 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).
- At a dry weight of 75 pounds, the Yamaha EF2400iSHC is one of the heavier inverters which can produce between 1500 and 2500 running watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Genmax GM2000i, with a dry weight of just 34.2 pounds.
- As its lowest possible noise is rated at 53 dBA, this inverter generator qualifies as one of the more quiet of the products of similar type and power. For those who are looking for a less noisy device, we suggest the Honda EU2200i. With just 48 dBA, it is one of the most quiet devices in this power range.
- Since the EF2400iSHC boasts with a run time of up to 11 hours at 25% load, it can be safely judged as a device of a higher run time than most inverter generators of a comparable output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Yamaha EF2800i, reaching 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. This inverter generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.15 GPH at a 25% load. If you wish to further improve in the area of fuel efficiency, the DuroMax XP2300iH, which boasts with a gas consumption of only 0.08 GPH, may be the right generator for you.
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
