Whether you’re traveling across town or across country, having power is a luxury that is difficult to live without, especially if you’re in an RV.

While camping in tents may be easier to get by, the need for running water and electricity in an RV is something that can often be taken for granted.

With the recent trend of campers and RVers flooding the world, many parks have incorporated power hookups to accommodate visitors. However, some RV parks are a little behind the times and may be leaner than others. 

Since electricity is a must to operate your water pump, air conditioning, or lights, having a generator by your side can alleviate future headaches and mishaps. 

Even if you’re not an avid camper, having a dependable generator can be a blessing in disguise when you least expect it.

If you’ve been on the hunt for a new generator, either for your RV or job site, then this review is dedicated to you.

Main Features

Now that we’ve covered a little bit of background, let’s see what’s under the hood and dive into the main features of this portable inverter.  


First off, one of the best features of using an inverter compared to a generator, is the model’s ability to match power output; this means engine speed is adjusted to match your needs at that moment.

Yamaha’s innovative, Smart Throttle technology automatically adapts to accommodate a variety of power needs.

If you’re using the Yamaha EF2400iSHC to power lights, the output will be constant; but let's say you’re operating a pressure washer, the inverter will spike in RPMs to keep up with the power demands when the pressure washer throttle is used.

This creative design contributes toward an ultra quiet unit that’s geared for maximum fuel efficiency.

With only 1.6 gallons of unleaded gas, the Yamaha EF2400iSHC can run for up to  8.6 hours at ¼-capacity load.


Another benefit integrated within the Yamaha EF2400iSHC is its user friendly, easy to manage design.

Constructed from an Aluminum die-cast frame, and fashioned with a lightweight flywheel and Aluminum TCI rotor, worrying about heavy lifting is a thing of the past.

Overall, this inverter weighs 75 lbs. (dry) and is equipped with two carrying handles on top of the frame.  


The design team at Yamaha did their part to ensure you receive the best when the topic turns to power output.

Don’t be fooled by its size, the Yamaha EF2400iSHC is a beast of a little inverter. The 171 cc, 5.5 HP, air-cooled OHV 4-stroke motor is plenty powerful and possesses High Current delivery.

As Yamaha states, “the High Current model starts most high efficiency 13,500 btu AC in temperatures up to 110° F.”


Lastly, this model used Pulse Width Modulation (PWM) to yield high-quality power to all electronics, similar to as if you were at home.

Due to this high-tech technology, users can use the Yamaha EF2400iSHC with any microprocessor device or appliance in full confidence.  


Below are the main pros:

Looks Great

Let’s face it - sometimes, looks matter. The last thing some people want when camping is to have to look at an old, rugged generator - especially one that’s loud and outdated.

Luckily, the Yamaha EF2400iSHC is extremely pleasing to the eye and can almost be seen as an accessory for those who have royal blue accents on their RV or camper.  

Easy to Transport

As we briefly discussed, the Yamaha EF2400iSHC is much easier to transport and carry than competing models.

Its lightweight, Aluminum design ensures that users can easily manage where it’s placed and for how long.

One major advantage of this model is that it can be set and packed up with in no time.

Compact and Powerful

Matched by its ultra-light design, this inverter is also extremely compact and can be quickly tucked away when it’s not in use.  

Since it measures 20.8” L x 16.5” W x 18.2” H, another great quality of this model is that buyers can store it in a number of places, unlike large, traditional generators.

Additionally, all while being compact, the Yamaha EF2400iSHC is extremely powerful. The 171 cc, 5.5 HP motor is perfect for supplying power to your phone and computer chargers, TV, or outdoor lights.

Environmentally Conscious

When it comes to the overall design of the Yamaha EF2400iSHC, engineers worked vigorously to instill trust that their model is environmentally conscious.

Another supreme quality of this model is that it’s CARB, USFS, and EPA emission protected in all 50 states.

Complemented by the unit’s quiet design, users can sleep easy knowing this model can be taken anywhere. Out with the old and in with the new as loud, gas hungry generators are a thing of the past.

Excellent Warranty

One of the best things we love about this model is it’s warranty.

Buyers agree that the Yamaha EF2400iSHC comes with your choice of a 1, 2, or 3-year limited warranty to add another piece of confidence to the package.


Below are the main cons:


The biggest drawback we came across is the price.

Due to the high-quality construction of the Yamaha EF2400iSHC, there is a heftier price tag associated with this model.

Bottom Line

Taking everything into consideration, the Yamaha EF2400iSHC is perfect for those who are on-the-go and looking for a dependable, powerful, quiet inverter.

Backed by a top of the line warranty and being environmentally friendly means no camping trip is out of reach - users can easily bring this along to power computers, phone chargers, lights, fans, etc.

As mentioned, the only drawback to this model is its price tag, which is a little above average compared to competing models.

The bottom line with the Yamaha EF2400iSHC is users can confidently place their trust in its innovative design and high performance engine. From those who’ve used this firsthand, they continue to see this as a sound investment.

Generator vs. Inverter - What’s the Difference?

More often than not, the term generator gets accidentally used as the word inverter. However, these two models vary in a number of ways.

If you’re guilty of using these words synonymously - and rest assured, you’re not alone - we’re going to break it down for you.

Generators consume raw power from the alternator while inverters recycle and clean the power for immediate use

Generators tend to weigh more while inverters are easier to manage and transport

Generators operate at a near constant cycling rate, yet Yamaha inverters match motor RPMs to the power needed - ‘when demand for power goes up, engine speed increases.’

What is the Yamaha EF2400iSHC Best For?
