There are a variety of generators out in the market, but perhaps, the Yamaha Ef2400ishc is your best bet.

This generator choice is not a surprise, since Yamaha, is a brand that has for a long time, been recognized to manufacturer high quality and durable products.

This 24000-Watt Yamaha Ef2400ishc lives up to Yamaha legacy with a powerful performance.

But will this unit take where you need to and will it meet your power needs?

To find out, we have compiled this comprehensive Yamaha Ef2400ishc review guide where we explore what this unit has to offer.

Yamaha Ef2400ishc Features and Benefits

Yamaha Ef2400ishc Generator Review


Power to weight ratio is one feature that arguably makes this unit earn the title of the best RV generator.

The Ef2400ishc comes with a pretty compact design; it has a relatively smaller footprint compared to other models of its caliber.

Weighing at 75 pounds and sporting a modest dimension of 19.3 x 11 x 17.9 in, you can easily pick up this generator and won’t dread moving it from one place to the other as needed.

Though it's light to pick by oneself, it can exert strain on your body, and this is why we recommend getting a helping hand to lift this unit.

When it comes to the construction, you will love the sturdy aluminum case on the outer frame of this unit. Expectedly, the aluminum frame makes this unit sturdy, protecting it against the drops and whatever nature may throw.

A major drawback we have seen on this Yamaha unit is the absence of wheels. This is quite a huge bummer, especially to the portability aspect as it limits maneuverability.


Remember we mentioned that the Yamaha Ef2400ishc has an excellent weight ratio, and weighing at 75 pounds, this unit boasts of a starting wattage of 24000 watts and a continuous wattage of 2000 watts.

Sure, this is not the highest power output we have seen, as there are other generators out there with a higher power rating.

But the good news is the output delivered by Ef2400ishc is enough juice to turn over any appliance running with 2,000 watts including a 10,000 BTU air conditioner.

With this unit, expect to run a variety of items including powering your RV, household essential such as refrigerators, microwaves, ovens, TV, router, sump pump, furnace blower, and if you are in the construction domain, you can use this generator to power a few items such as saw or small air compressors.

Also, this unit has the capability of powering a 13,500 BTU air conditioner. However, rest be assured, you won't be able to run other appliances when running an air con of such demands. In my view, we don't recommend running such an appliance as it might compromise on the longevity of your generator.

Inverter Technology

The best part of the power output from this unit is that it's clean.

Being an inverter generator, this unit uses advanced circuitry to deliver clean power free from the troubles of power fluctuation, or surges.

The clean output of this unit makes it a more inspired choice for use with extremely sensitive electronics such as laptop, smart TVs, and phones.

You can now comfortably use your generator on virtually all electronics that suffer from electrical overload without having to worry they will get harmed.

Fuel Type and Fuel Efficiency

Powering this unit is a 4-stroke 171cc, OHV engine. The drivetrain on the Yamaha has an air-cooling feature that helps the unit to cool and prevent overheating.

This Yamaha unit has a fuel capacity of 1.6-gallons and runs on regular unleaded gasoline. Though the tank is not quite voluminous, it offers a generous runtime of up to 9 hours when operating on a ¼ load. This runtime is more than enough to take you through the night and even throughout an event during the day.

While running at ½ load, you can expect a run time of up to 6 hours, which to me is still a bargain.

A major contributor the Yamaha’s fuel efficiency is the smart throttle feature. This feature helps in varying the engine speed based on the load or rather the amount of stress you put on the generator.

Unlike the conventional generators which run on a constant speed regardless of the power being drawn, the smart throttle feature will reduce the speed of the motor if the load is small, and this will help to conserve fuel.

The benefits of this adjustment are that it will not only optimize on the performance, and fuel efficiency of the unit but ensure that it runs for the longest period.


While the extent of the noise generated by this inverter generator depends on the stress you put on the unit, it makes an incredibly low level of noise which you are bound to love.

At the lowest levels, the Yamaha will generate 53 decibels, which to my opinion is relatively quiet and will allow you to hold a normal conversation without disruption.

When more appliances are on use, the noise is a tad louder, but will not exceed 60 decibels.

Convenience Features/ Ease of Use

Highly versatile, the Yamaha Ef2400ishc has multiple outlets for the ultimate convenience. Sporting 2 AC outlets and a single DC outlet, this unit will allow you to connect up to 3 appliances at a single go.

However, it’s a shame that it does not feature a USB port or any 220V outlet.

When it comes to ease of use, you will love the centralized control system that has all the control features in a single and easily accessible panel for easy use and reach.

The gasoline petcock is yet another convenient feature that will allow easy draining of gas for dry storage.

Conclusion: Is the Yamaha Ef2400ishc Right for You?

If you are in search of a powerful, reliable and durable inverter generator, the Yamaha Ef2400ishc is right for you.

The absence of wheel and the lack of a 220V are the only possible drawbacks we saw on this unit. They are not quite a deal breaker, and most of us can do without these features.
