Yamaha EF2400iS Generator Review

Rating: 4.0 / 5.0

Camping is one of the most interesting endeavors that we engage in during our leisure time. However, as a camping enthusiast I will definitely tell you that you cannot afford to exclude a power source from your camping checklist. Over the many years that I have been going for camping with my family, I have come to understand the importance of having a reliable power source. 

Sometimes the weather becomes so adverse in the outdoor setting to a point that we cannot light fire to cook. This means that we have to start relying entirely on our canned food which still requires to be warmed before consumption. At this point, I find it inevitable to use my Yamaha EF2400iS Generator to power my microwave to warm the food. You might be having questions like; what are the most important considerations to make when purchasing a camping generator? Why are these considerations important?

Why is Yamaha EF2400iS the Best Camping Generator for you? Below are the answers to your questions.


You need a generator that is highly portable in order to be able to move from one camping spot to another with ease, and also protect it from adverse weather by moving it in and outside its tent when necessary. In this case, Yamaha EF2400iS generator is the best because it is small in size and it has strong handles that makes it highly portable.

Environmental Friendliness

As a camper, you need to uphold environmental ethics in order to preserve the provisions of nature for future generations. In addition, you also need to take into account the fact that you might not be the only camper in your area. Therefore, it is unethical to use a generator that is so noisy that it disrupts the attention of other campers within the area.

According to Cannolly (2014), Yamaha EF2400iS is one of the most quiet generators in the market. It is installed with a 54 dBA which makes it very quiet at a distance of seven meters. This quality makes it suitable for camping because it adheres to the set ethics for campers. All camping enthusiasts bear in mind that they have a role of protecting the environment and leaving the wild fauna undisturbed while engaging in their activities. For this reason, Yamaha EF2400iS becomes your best choice.

In addition, the generator uses effective inverter technology that produces clean power which is able to power sensitive electronic devices such as laptops and mobile phones without exposing them to the risk of power surge.


You need a generator that is easily serviceable in order to avoid unnecessary inconveniences during your camping. When making my purchase decision, I settled for Yamaha EF2400iS because of the fact that it has easily detachable side panels that ensure easier serviceability. In fact, I can also attest to the fact that the generator is highly durable and it does not experience unnecessary breakdowns.

Over the period of three years that I have been using my generator, it has never shown any signs of poor performance. I have been servicing it by myself through following the guidelines on its manual which are clear and understandable. This factor has saved me a lot of money that I would have spent hiring an expert to undertake regular servicing.

Fuel Efficiency

We both know that most camping grounds are not near any fuel stations. This means that you will be expected to carry with you adequate fuel for your generator. For this reason, you need a generator that is fuel-efficient in order to reduce the overall amount of fuel that you will be required to carry. Moreover, this is a factor that cannot be ignored since it has serious implications on the total cost of operating the generator.

I conducted a fuel efficiency test on my generator and found out that it can run for 9 hours on 6 litres of fuel. At first, I was surprised to note that Honda EU20i could run for more hours on 4.1 litres of fuel since it's manufacturer had indicated that it can run for 10 hours on a full-tank. I became a bit curious and started undertaking research to find out whether Honda EU20i had a higher fuel efficiency. To my surprise, I found out that my generator was more fuel-efficient according to a study that was conducted by Connelly (2014).

User friendliness

It is very frustrating to realize that you cannot use your generator when you need it due to the mere fact that you do not understand how to operate it. Therefore, it is important for you to consider the user-friendliness of your generator before you make a purchase. Yamaha EF2400iS stands out from other generators when it comes to user-friendliness. It is installed with a recoil start which makes it easy to use. In addition, it comes with a clear and understandable manual that guides you on how to operate and service it (Yamaha 2017).

Pros and Cons


From the above properties of Yamaha EF240OiS, we can see that it is user-friendly, fuel-efficient, environmentally friendly and portable. However, there are other advantages of the generator that I have not been addressed in the section above that include low emission level and high value for money.

According to Anaconda (2017), Yamaha EF2400iS enables you to cut unnecessary expenditures such as regular repair and maintenance costs that you would have spent if you were using a low quality generator. In addition, its fuel efficiency translates to low emission levels hence making it suitable for use in the outdoor setting.

Moreover, Yamaha EF2400iS produces 2000W continuous output and 2400W peak output which is enough to power an air-conditioning unit, micro wave and even television.


There are two key disadvantages associated with the generator that include heaviness and high initial cost (Tentworld 2017). The weight of the generator might discourage you from carrying it to your camping ground if you do not have reliable means of transportation. In addition, it commands high initial cost of $2050 which you might perceive to be too expensive.

Below are the key features of Yamaha EF2400iS that proves that it is the best camping generator for you this year;

  1. Noise level suppressor
  2. ​Inverter voltage regulator
  3. ​Pilot lump
  4. ​Oil level warning system
  5. ​Electronic circuit breaker system
  6. ​Fuel level gauge
  7. ​Auto decompressor
  8. Brushless alternator


Yamaha EF2400iS is the best camping generator for you this year. This product is environmentally friendly hence making it suitable to use in the outdoor setting since it does not cause high pollution to the flora and fauna. In addition, bearing in mind that it has high power output and it is fuel-efficient, it assures you that your power needs will be sufficiently addressed during your camping period.

However, I would like to advise you on two things that might interfere with the effectiveness of this generator during your camping period. First, extreme temperatures can cause reduced power output. In fact, research shows that every increase in temperature above 25 degree celcius by 5 degrees celcius reduces power output by 10% (Connelly 2014). Secondly, long cords can also reduce the power output. Ensure that the cord that you are using is not more than four meters in length. Meanwhile, do not hesitate to purchase your Yamaha EF2400iS generator from any of the leading stores.
