BRIGHT LIGHTS, SMALL PACKAGES. The EF2400iSHC inverter combines light weight and the latest technology to produce the highest output in its class. (source: Yamaha (opens in a new tab))

Zoom on the Yamaha EF2400iSHC

In a nutshell, the Yamaha EF2400iSHC is a quiet and compact portable inverter generator mostly geared towards:

  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go
  • DIYers who wish to improve their efficiency with tools

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Yamaha EF2400iSHC in use

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 2000W and reaches a peak wattage of 2400W.

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).

Sensitive electronics can be safely plugged in the AC outlets, as the EF2400iSHC produces a clean sine wave, with a <2.5% Total Harmonic Disruption (THD).

Outlets

The control panel features the upcoming 2 AC outlets:

Duplex 120V 20A (5-20R)

Furthermore, it has 1 DC outlet: there's a 12V 8A receptacle with which you may charge your batteries with ease.

Portability

Thanks to its closed inverter generator design (L20.8 x W16.5 x H18.2 in), the Yamaha EF2400iSHC, is more esthetical than a typical, open frame generator. This modern design aims to provide an ideal power solution to recreational users.

The EF2400iSHC can be taken anywhere with you, thanks to its weight of 75 lbs. In addition, its nifty double handle improves your grip, allowing for an easy transport of the EF2400iSHC from place to place.

Features

Panel of the Yamaha EF2400iSHC

The EF2400iSHC's control panel

Several light indicators serve to show you when the generator is overloaded, the generator is ready and the oil level is too low.

The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its 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. 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 generators of similar power (between 1500 and 2500 W).

  • As its dry weight is 75 pounds, the Yamaha EF2400iSHC is one of the heavier of the products which can generate 1500 to 2500 running watts. Regarding dry weight, one of the champions in the same power range is the Champion 200949, with a dry weight of only 38.6 lbs.
  • With a lowest possible noise of 53 dBA, this inverter generator places itself amongst the more quiet of the products delivering similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU2200i with only 48 dBA.
  • The EF2400iSHC, falls within the average autonomy range compared to generators of a roughly same power, with a run time of up to 11 hours at a 25% load and a full tank. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse WGen2000, which is able to run for up to 26 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. 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 you wish to further improve in the area of fuel efficiency, the Predator 2000, which boasts with a gas consumption of only 0.08 GPH, may be the right generator for you.
According to our stats, the following comparison is pretty popular: Yamaha EF2400iSHC vs Yamaha EF2000iSv2.

Price comparison

As you can see from this interactive chart, when compared to other 1500-2500W generators, the Yamaha EF2400iSHC is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
