Generac GP3000i vs. Honda EU3000iS Inverter Generator

Honda vs. Generac is a classic case of where you can get a cheaper model generating the same power as the expensive model.

In such a case, you would not be sure to choose which one for the power.

The Generac GP3000 and the Honda EU3000iS generators are both good in terms of power output. With all their power being smooth and clean, you can easily power your sensitive electronics using the two generators.

We will look at these two generators in detail so that you make an informed decision. The last thing you want is to make a rushed decision and regret later. Let us check them out in detail below.

What to Look For

Understand Your Power Needs

Each time you are looking for a generator, the power needs are the most important considerations. Make sure that you get a generator that can handle your power needs on overall.

Start by listing all the things you hope to power with your generator. It is from the numbers that you can get the generator size.

Now that you know the generator size, try to oversize it too. This ensures that you can have an allowance of running the generator for longer without it running at its highest speed all along.

When looking at the power figures of the generator, consider its starting watts and the running watts. You should focus more on the running watts as that is the power that would be available when running the generator.

The Fuel Type

The fuel type is important to determine the performance of the generator on overall. The most common fuel sources would be diesel, gasoline, and propane.

The diesel generators are best for cases where you need more brute power at any time. Most people would however shy away from them when it comes to emissions. They can also be expensive to make them emission compliant.

The petrol or gasoline generators are liked for being fuel efficient, powerful, and generally good with the emissions. They can also be powerful compared to some other units in the market using other types of fuel, especially propane.

The propane fuel type is often used as a backup fuel source. You might get it being part of a dual-fuel generator so that you can switch to it when the other fuel source is over.

Noise Output

You cannot ignore the noise factor. You always have to consider the amount of noise that the generator makes before choosing the best one for your home or RV.

There are some models that would make a lot of noise even for a portable generator. Making too much noise might make other people in the same neighborhood uncomfortable.

As much as a generator is likely to make some noise, it should be within the reasonable amount.

Depending on the design of the generators, there are times when the generator would make a noise similar to having a conversation. It is easy to see why such a generator would be ideal for your home or RV campsite.

Always look at the noise level in the product description section to understand what kind of noise the generator makes.


When looking for the best generator for the job, you also have to consider the reliability. You cannot imagine spending most of the time repairing the generator when it should be running and providing you with the best power.

The reliability factor will vary from one brand or model to another. Sometimes you would have to do more research to understand the unit’s reliability even better.

The reviews on the generator can be a nice way of learning about the generator reliability. Just make sure that you take your time to check out the genuine reviews. The last thing you need is to rely on some paid reviews that have no value to your need of buying a generator.


The installation process will vary from one unit to another. Some units will be easy to set up while others might need the help of an electrician.

Luckily, manufacturers now understand the importance of making user friendly generators. It is why right now you can get generators that are ready to plug and play without hiring an electrician.

If you have to connect to the house, a model would have a transfer switch ready outlet and many other options that make connecting to the inverter generator easy. The same applies to when you want to connect to the RV too.

Size and Weight

The size and weight are important considerations for anyone who needs to get a portable generator.

If you are aiming for a portable model, then get one that is compact and lightweight at the same time. This will make it easier to get the model into position with ease.

If it ends up being a bit heavier, then the manufacturer needs to incorporate some features that would make it portable. This will include wheels and handles that help in getting it to where you want with ease.
