Generac vs. Champion Portable Inverter Generator [Recommended]

When you want to head out for a nice time outdoors in an RV, then you need the best generator to provide you with all the power that you need.

If you are planning a trip soon, then the Generac Gp2200i and the Champion 3100-watt generators should be top considerations.

The best part about these two generators is that they can still power your house. You can use them as power backup sources to keep the electronics running until the power outage is resolved.

Let us check out the various things to consider when choosing a generator and then after review the two generators mentioned above.

What to Look For

The Generator Size or Capacity

One thing that you should always consider is the generator size or rather the power that it generates.

Each time you want to buy a generator, you need to get one that can deliver the best power to meet the power needs of your RV or home.

This might mean that you calculate the electrical load in the house so that you can pick the correct one for the job.

The last thing you need is to end up overloading your generator. This can damage the engine plus the inverter. These two are costly repairs and sometimes you might just have to replace them when it becomes apparent repairing them is not the way to go.

So, look at the rated power of the generator then use it to work out its performance with your electrical load. With the right size of generator, then you should not have to deal with overload issues.

Modular Capability

Modular connectivity is something that more manufacturers are now adopting because of demand.

Modular connectivity is when you can parallel two generators to double the power. Let us say that in the future the electrical load surpasses the current power output of the generator. Rather than buying a bigger generator, just get the same generator and connect them together.

Other than doubling the power output, the paralleling capability means that you have one generator running even if one fails after a while. Also, the cost is a lot lower when you parallel two generators than when buying a bigger one.

It might not be mandatory for a generator to have this feature, but it would be nice to have it available.

The Controls

You always have to consider how easy or hard it is to control the generator. More manufacturers are now making user friendly generators. They know that users want to use the generators more often and would not have someone who understands the generators technically.

It is why more models are now designed to be RV ready or transfer switch ready. This means that once you get the generator, you simply plug it in and you are good to use.

As such, you will not need to have an electrician each time you want to set up the generator.

Also, the placement of the controls can make it easy or hard to use the generator. If the controls are neatly arranged and labelled, then it should be easy to configure the generator to work great as expected.

Fuel Efficiency

Another thing you have to consider is fuel efficiency. Fuel efficiency is often measured in terms of the number of hours the generator can run without refueling.

The fuel efficiency widely varies from one unit to another. It is something you always have to take a keen look into before buying the generator. The last thing you need is to keep refueling the generator just to keep it running correctly.

Sometimes you can get that a model has the economy mode. This is when the generator can adjust its power output so that it runs the engine at low speeds and also it reduces the noise level.

Generators that can match their engine speed to the load are great in terms of improving fuel efficiency. You can find them running for longer on a single tank of gas.

The Physical Size and Portability

These two go hand in hand all the time. If a generator is too big, then it would hamper its portability.

So, it depends on where you want to use the generator. It would be mostly used for RV applications, then it needs to be a compact and portable generator.

Even those that have to be used at home would need some features that aid with portability. Such will include the wheels, handles, and more. The idea is to keep the generator easy to transport whenever necessary.


It is always great when the generator you are using is a quiet one. It might take a bit of digging around, but it is possible to get yourself a quiet generator. What is important is to get a generator that will not keep you or the neighbors awake.

To understand the noise levels of a generator, look at its rated sound. It will be a figure accompanied by dBA as its units. Manufacturers are always proud of their silent generators, so they will not forget to highlight them in their product description.

Having a lower dBA is what you should be looking for.
