The engine will give you running power output up to 4,000 watts and its surge power is at 4,500. There is a 375cc OHV and so you can adjust the power to your needs because you will be able to lower the fuel consumption and noise rate.

Another thing that is also great is that the EF4500iSE generator has an electric starter which is convenient option for many users. The electric starter uses 12 volt 18 amp battery which can be a little problematic to charge it. However, the upside to this is that you can start the generator no matter how rough the weather condition is. Also you need to charge the battery when you’re not using it if you want the generator to be in perfect condition when you do want to use it.

How powerful is it?

With this generator, you will be able to power up any home appliances as it produces just enough power for it due to the large oil tank. This is also great because the generator can be used either when you want to go camping or when there is a blackout and you need to use it at home. With that being said, the generator can run appliances such as TV, refrigerator, the microwave as well as AC of course.

The receptacles the EF45000iSE uses are two outlets. One of the outlets is 120 volt and the other one is 120 volt/240 volt. Even when you are running the AC, the generator will be able to provide a lot of power. The generator has a great fuel efficiency and performance. The fuel tank can store up to 4.5 gallons of oil. This means the run time is 15 hours on a quarter load with a full tank. This way you can use it for camping and leisure activities but the generator will also be ideal for home use and DIY applications. Considering it produces clean power, the generator can be used for RV as well which can power your appliances. The RV is very quiet according to many customers and the AC almost always starts very easily.


The EF4500iSE is also very durable, made to withstand any sort of damage. It also comes with four wheels and a dual handle for extra portability and transportation. Even though it’s small, it’s also very heavy so lifting it could be a problem. It weighs 194 lbs and is 30.7 inches long, 24.3 inches wide and 27.2 inches high. It also comes with an LED display to let you know about power consumption and an hour meter so you know if there are any needed repairs.

Noise levels

A lot of people will be interested in how much noise this generator makes. The Yamaha EF4500iSE is actually very quiet and is perfect for any sort of environment because of it. There is a sort of insulation layer which will reduce any sort of noise to the point you don’t hear the generator anymore. At 8 meters apart, the noise rate is at 58 or 60 decibels when it is at quarter load. Of course, when the generator is running at 50 percent or higher, the noise rate will be higher and it is at 67 aor 69 decibels. All in all, it’s not a noisy generator and can be used almost anywhere.

2. Honda EU2200i

Honda EU2200i Generator for RVDesign and convenience of the EU220

When one takes a look at the EU2200i, they can notice that the design is quite similar to the one of older generations. The colors used on the housing are typically red and black. The generator also comes with a handle on the top which runs along its length. The tank is quite small as well but it takes up most of the space either way.

This generator is extremely user-friendly and easily carried around making it very portable. It has a color-coded system with four steps and the user can easily follow it to start the generator with the manual recoil. Other than that, there is even the fuel shutoff system which immediately shuts off the engine when the fuel levels are low. One can also find large parts made for oil control. The generator is also very quiet, making only 48 dB of sound at quarter load and 57 dB at rated load.

How capable is this generator?

The EU2200i generator has an upgrade in terms of power when compared to its previous models. There are 2200 watts of surge power and 1800 watts of running power. This generator also supports an eco throttle system. In much simpler terms, the maximum run time is eight-point-one hours at quarter load on a full fuel tank. This also makes it energy efficient.

The fuel tank that the generator comes with is very small, under one gallon even. It has a great efficiency on small fuel tanks so it’s pretty much expected that this generator is also affordable to run. The EU2200i model is much more durable model because it has a better manual recoil system than the older generation. Other upgraded things are electronic circuit breakers, it also has an increased ventilation and one can find a new stator/rotor. This new stator has magnets which it uses to make much cleaner electrical outputs.


When it comes to specifications of the EU2200i model, one can notice that they are quite standard for 2000 watts category. The model is very portable because it’s very light but also comes with a handle and it weighs less than 47 pounds. Because this model has 200 more watts than the previous model the EU2000i, it supports more connections. These connections can include a TV, blender or a coffee pot for home usage or to turn on an electric saw for a work site.

The generator also comes with an AC output of hundred-twenty volts and a DC output of 12 volt. On the downside, however, you can’t use the DC output if you haven’t bought extra accessories. These extra accessories are necessary for connecting the generator to a car battery, for example. The generator also allow parallel connection and it is the best way to use it if you want an AC. It will allow you to run several devices while the AC is running as well.

What does this generator run on?

One can only use gas to run the generator and nothing else. Like said previously in the article, there is a very small fuel tank of 0.95 gallons which has a screw top used to be refilled. A lot of times when the fuel tank is small like the one here, it’s expected that the run time of the generator is short too. But because the energy efficiency of this model is so great, the run time is 8.1 hours at quarter load.

The reason why such run time is even possible is because of the 121cc GXR120 engine. The 121cc GXR120 engine is designed mostly for heavy duty industrial equipment. This engine is also light and very quiet but still manages to produce relatively good power.

How the EU2200i works and how to use it?

In this model, Honda didn’t decide on adding a push start but focused on making the manual recoil system better. This means that starting the engine is made to be very easy because it doesn’t need a lot of strength to do so. That’s because there is an automatic mechanical de-compressor. This model is also very user-friendly because a lot of features were included that prevent any sort of damage that could be made to the generators. This makes the generator more low maintenance.

The example for the low maintenance of the generator is the low fuel shutoff. This makes the generator to shut off immediately in case the fuel levels are low. This also adds extra protection to the engine. Another thing that adds to the protection is the automatic circuit breaker. This automatic circuit breaks automatically turns off the generator in case of overloading or unstable electricity. But in general, this feature is quite common for most generators.

There is also the oil control feature. The generator comes with a very big opening for the oil as well as a large spout and oil drain gutter. It automatically makes it easier to change the oil of the generator without much of a hassle.


– Extremely quiet

– Extra protection against damage

– New stator/rotor

– Great energy efficiency despite the small size of the tank

– Parallel connection

– Can run either 13,500 or 15,000 btu air conditioner


– Limited fuel capacity
