Honda vs. Yamaha 3000 Watt Inverter Generator

Honda and Yamaha generators are easily the best to buy when you do not have to worry about the budget. As much as the two brands are not known for having cheap generators, their models are good in every other way imaginable.

The generators we will consider for this review include the Honda EU3000iS1A and the Yamaha EF3000iS models. The two have the same power output and are portable for outdoor use. So, which one would you choose?

We will discuss more about these generators in detail below, but first, let us look at the buying tips for inverter generators.

What to Look For


Since we are talking about portable generators, then the overall portability of the generator is important.

Things that will affect the portability of the generator include the weight and size.

Look at the dimensions of the generator to establish if it will be portable or not. Another thing to consider is the overall weight. For a generator that weighs below 150 lbs., then it will be possible to transport it with ease.

Still on portability, a generator that comes with additional wheel kits and handles will make it easier to move the generator. There are some that have brakes on their wheels so that the generator stays in position when it is running.

Power Delivery

This is a major consideration for anyone who wants the best generator for the money.

The amount of power that you get out of the generator determines how many electronics can be connected to it.

Before you can buy a generator, sum up all the electrical loads that you expect to connect to the generator. It is from this summation that you can know which generator will have enough power to handle all the electronics.

There will be two types of power on the generator label. There is the peak power and the rated power. Focus more on the rated power.

The rated power is the amount of power the generator can deliver continuously while it is running.

The peak power is available when the generator is starting or when there is a large draw of power in a short time.

Fuel Efficiency

Anyone who decides to get a portable generator will always consider the fuel efficiency that comes with the generator.

The fuel efficiency is determined by the number of hours the generator can run on a single tank of fuel.

There are some that can provide you with up to 20 hours of runtime when running at 25% load capacity. So, if you increase the load, then the hours can reduce.

Nevertheless, the run time is an important factor for someone who does not want to keep refueling the generator all the time.

Taking an example of a generator that can run for 20 hours, it is easy to find it being an ideal choice for overnight use without waking up to refuel the generator.

Noise Rating

If you can get a portable generator with low noise levels, it is easy to see that it would help you achieve the best performance while no irritation at all.

There are various models in the market that have low noise ratings. So, it should not be hard to get one for yourself today.

If you hope to use the generator overnight at a campsite, go for a unit with a noise rating below 60 dBA. Manufacturers are always proud of a low noise generator, so the rating will easily be in the product description or spec sheet.

There are some generators that come with a smart throttle mechanism. This type of throttle is good as it reduces the engine speed when the load is low in turn reducing the noise too. So, even for a quiet generator, it can get quieter.

Control Panel

The control panel of a generator is essential for giving you all the important information on how to operate the generator.

Look for a generator that has clearly laid out controls to make your job of operating it easier.

Some of the information you can get on the control panel include the power the generator is making, runtime, total hours, outlets, and so much more.


The number of outlets is crucial to determine the number and type of devices you can connect to the generator.

You need a generator with both AC and DC outlets. This allows you to connect different types of devices with ease.

There are new models that now come with USB ports. Such ports allow for connecting to the generator with ease without an extension cord. As much as it is not a must to have USB ports, they are an added convenience for most people.

Ease of Starting

There is no doubt starting a generator can make you hate or love using the model.

To make it easy to start a generator, many brands are now using electric starters. You simply press a button to turn on the generator.

Even if the generator comes with a recoil start mechanism, it can still be easy to use. Newer generators that have a recoil system often that needs one or two pulls to start the generator. That is not bad at all even in cold starts.

The smart eco-throttle of the generator is also an important factor. This is because it can provide you with the performance that matches the load.

The throttle reduces the engine speed when the load is low and vice versa. It is easy to see that the generator can also reduce its noise even further when the engine speed slows down.

Inverter Technology

Honda is one of the top brands with an advanced inverter technology. The result is that you end up with reliable power for various devices in the house or RV.

The inverter technology is also great for helping you achieve clean stable power. This means that you can use the generator for different applications even where sensitive electronics are being used.
