Everyone recognizes and associates the Yamaha name with motorcycles and engines and the quality and stability of those products.

The Yamaha EF2400iSHC Portable Generator does not disappoint and is another example of the quality of the Yamaha name.

There are many things that make this portable generator valuable for anyone who wants to have the capability of powering several high wattage items at once during a power outage.

It’s been issued emission engine durability ratings by both the EPA and the California Air Resources Board.   When looking for an excellent portable generator with a lot of capacity, this is a great choice.

Fuel Type, Efficiency, Capacity and Run Time

The Yamaha portable generator uses unleaded gas as its fuel source, holding 1.6 gallons of fuel at once and providing users with 8.6 hours of run time when operating at 25% capacity and 6.5 hours when running at 50%.  The engine’s speed is regulated by the Smart Throttle feature which provides better fuel efficiency and savings; something that all users are looking for in a portable generator.  Even though it doesn’t have an economy mode like the iS models do, it still is able to lower the power needs and thus enables a savings.

You will never run out of gas with the fuel gauge that allows you to see how much gas you have with just a quick look.  The fuel tank filter is designed to protect the tank by keeping larger particles from getting into it.  Another feature is the fuel shut off value which is not always available in other models.

Oil Requirements

One of the pluses of this portable generator is that there is no need to mix oil and water together the way some devices need.  You can find both the drain plug for the oil tank and the fill hole behind covers.  Be careful not to have any spillage when filling the unit with oil. One of the best ways to avoid making a mess is to purchase a long tunnel that I designed for a bit more out of the way ports.

You will want to use regular SAE 10W-30 or 10W-40 weight oil and can expect to put in a little over a pint of oil. Check it regularly to ensure that there are no leaks and that it does not need to have oil added.  If you’re ever changing the oil on your Yamaha portable generator, you will need a 12mm socket and wrench to remove the drain plug.

How Noisy is it?

Noise level is always something users take into consideration when it comes to purchasing the right portable generator.  If it’s being used for camping, campgrounds and state parks often have regulations that must be followed when it come to noise level so it doesn’t disturb the other campers.

One of the top features that the Yamaha portable generator has is the Noise Reduction which ensures very quiet operation for the user.  The output of noise is between 53 and 58 dB of noise which is the equivalent of background noise that fades into all the other noises that go on. It might be more discernible at night, but not so much so that it would prevent sleep.

Wattage (continuous and maximum)

Yamaha EF2400iSHCaYour Yamaha EF2400iSHC provides a continuous output of 2,000 watts and a surge output of 2,400 maximum watts. This means that it has a surge increase of 400 watts.

You will be able to power equipment that is 120v and that can require up to 16 amps of electricity. This will enable you to run all of your essential equipment in the event of a power outage which can provide a lot of peace of mind.

Since this model has a high current output, it is perfect for starting electric motors on your different devices as well as starting air conditioners as well.  One very important aspect of this model is that it can be used to run sensitive computer controlled equipment without fear of damaging the sensitive systems.

This is called Pulse Width Modulation. This generates electricity that is on par with public utility companies in terms of quality.  It can even be use to power electronics with microchips with no danger of damaging them.
