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
  • Amateur DIY lovers

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 houses a 171 cc Yamaha MZ175 OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 2000W along with a peak wattage of 2400W.

The inverter generator is rated for a noise of 53 dBA (just slightly more noisy than a refrigerator). 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 fuel capacity of 1.6 gallon allows the EF2400iSHC to operate 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 provides the upcoming 2 AC outlets:

Duplex 120V 20A (5-20R)

It also sports 1 DC outlet: there's a 12V 8A receptacle allowing you to easily charge your batteries.

Portability

As the Yamaha EF2400iSHC is an inverter generator, its encased design (L20.8 x W16.5 x H18.2 in) offers more aesthetics than a conventional, open frame product. The generator has a contemporary design, convenient for recreationally generating power.

The EF2400iSHC's dry weight of 75 lbs lets you use its power anywhere needed. Moreover, the convenient double handle greatly enhances the grip, making displacing the EF2400iSHC from A to B always an easy task.

Features

Panel of the Yamaha EF2400iSHC

The EF2400iSHC's control panel

The light indicators show you if the generator is on overload, the generator is ready and the oil level is too low.

Thanks to a built-in fuel gauge, the inverter generator allows you to quickly, conveniently and easily check the gas level at a glance.

From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Watch system), allowing you to 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, which makes it suitable 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).

  • With its weight of 75 lbs, the Yamaha EF2400iSHC is one of the heavier generators in the 1500-2500 rated wattage category. Regarding dry weight, one of the champions in the same power range is the WEN 56202i, with a dry weight of only 38.6 lbs.
  • Since this inverter generator is rated for a lowest possible noise of 53 dBA, it can be considered as one of the more quiet of the products generating similar 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.
  • Given that the EF2400iSHC reaches an autonomy of up to 11 hours with a full tank and at 25% load, it is placed within the average autonomy range of similarly powerful generators. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Westinghouse WGen2000, boasting with up to 26 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption 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 expensive side of the price range.

While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.

The bottom line

STRENGTHS:
  • Inverter
  • Quiet for its power (53 dBA)
AVERAGE SPECS:
  • Decent run time
WEAKNESSES:
  • On the expensive side
