Yamaha EF2000iS Generator Review

Running Watts

The running watts of a portable generator not only affect how much strength you will need to use to run the generator (whether it be battery or fuel) but it will also affect how many appliances you can run off the generator at any one time. For example, let’s imagine that you were camping and you need a appropriate portable generator – you may want need to run cooking appliances and lighting all at once in the evening time and this will probably be the most electrically intensive time of the day. So what you need to do is add up the wattage of all the appliances which you’ll need to use simultaneously and then make sure that the generator which you choose can produce enough wattage to run all these appliances.

The Yamaha EF2000iS comes with 1,600 watt rated AC output and a maximum 2,000 watt AC output.

Engine Specifications

This generator from Yamaha comes with an air-cooled, single cylinder, 4-stroke engine which can produce up to 2,000 watts of electricity as mentioned above.

The tank in this portable generator is quite large as it can keep up 1.1 gallons of fuel.

Maximum Run Time

One characterize which makes this generator so efficient is its Smart Throttle Load characterize – this allows the generator to dynamically adjust engine speed depending on the required output which method that less fuel is burned during time of low dependance, saving fuel.

The Yamaha EF2000iS can run for 10 and a half hours at 1/4 rated load and while operating in economy mode.

Starting Method

All you have to do to start the EF2000iS is flick the little switch on the front of the generator to “on” and then pull the draw cord to get it up and running. This definitely isn’t the easiest starting method out there as it truly requires some effort to get the engine going – but it’s also not the most difficult starting method either.

Operating Noise

Something which is very important when it comes to choosing a generator is how loud it is, so that’s the next thing which I shall discuss in this Yamaha EF2000iS Review. With its perky little engine, this generator operates at 51.5-61 dBA.

There are two AC outlets on this generator which are used for charging most appliances in addition as a DC outlet which allows you to charge batteries in addition – a very nice addition.

This portable generator from Yamaha is CARB compliant.
