But for light to medium-duty applications, this will be more than enough. It has a running wattage of 3000 watts and a peak power of 3500 watts.

Pull-Start Mechanism

This is a conventional generator, so it relies on the traditional pull method to start the engine. This can be quite a work for some people, especially because there are instances when it will not immediately start. It would have been better if there is a push-button for an electronic start.

How to Choose Generac Generators

It can be quite overwhelming to pick the best Generac generator, especially if you are a first-time buyer. To help you decide, this section will talk about some of the most important considerations.


Among others, the most important consideration is the capacity of the generator. There is no magic number when it comes to what works best. At the end of the day, your needs will be different from others, so take the time to consider your power consumption.

To determine the appropriate capacity, consider the appliances that you would like to run at home or the campsite, among other places where you need a generator. Get the total and this will determine the wattage that you need. Take note that the larger the capacity of the generator is, the bigger it will be. To add, it will also be more expensive.


Speaking of capacity, the engine is an important part of the generator that deserves your attention. This will be indicative of power and performance. So, consider how powerful the engine will be and match it to your needs. The intended application will help you decide on what engine will work best.

You need to look at two main technical details when determining the power of the engine. The first is the starting watts. This will be the extra watts needed for a few seconds when you start the appliances connected to the generator. On the other hand, running watts will be the continuous watts necessary so that the appliances will keep on running while they are connected to the generator.


The size of the Generac generator is important for portability. A lot of generators are not used at homes but in RVs or campsites. So, you need to find one that is as compact and lightweight as possible, which also means that it will be easy to bring around.

There’s no problem in choosing a larger generator, especially if you need one that’s more powerful. If this is the case, however, consider the features that will improve portability. For instance, it is necessary to have rubber wheels. To add, there should also be ergonomic handles. With these, even without a helping hand, moving the generator around will be easy.

Best Generac Generators


Since the time generators were introduced, the noise has been a persistent issue. It can be disturbingly loud, so pay attention to the noise output that the generator can create. Look at the decibels. The higher the number is, the noisier it will be.

Fortunately, many of the Generac generators are quiet. They are equipped with innovative features to dampen the noise created by the engine. As a result, you can use it even in campsites, especially in natural parks with stringent requirements regarding the noise outputs of generators.

Fuel Tank

The tank is one of the most important parts of any generator. It should be made of durable material. In most of the products that are briefly reviewed in this article, steel is used, so you can be confident that the durability will be second to none.

More than the material, the capacity of the tank is a crucial consideration. This will dictate the runtime. Most manufacturers will indicate this in gallons or liters. For the runtime, take note that the number of hours noted is often based on a 50% load capacity.

 Generac GP3500iO


As you try to narrow down the possibilities, consider the various features that will be indicative of the safety of the generator. For instance, one of the most important is automatic shut-down in case the oil level is low. This can also protect the engine and make it long-lasting.

It is also good to choose a generator that comes with overload protection. In many instances, you might be unconsciously plugging appliances with more capacity than what the generator can provide, so it is great if there’s a protection against such situations.


Consider how many outlets you will need. This will dictate how many appliances can be connected to the generator. For instance, if there are two outlets, then you can connect only two appliances. You should not use an extension cord to multiply the capacity.Also, some generators are equipped with a USB port. This way, you can easily charge compatible gadgets, such as smartphones and tablets. It is also a good thing if the outlets will come with covers. These will protect the plugs from dust and dirt, among other factors that can speed up wear.

Best Generac Generators


In the case of the Generac generators that we will be talking about later on, the warranty lasts for two to three years. It is good to have long warranty coverage, which means that you can rely on the support from the manufacturer if there is a defect or issue with craftsmanship. However, do not forget to read the terms and coverage so you will know exactly what will be covered by the warranty.

Types of Generac Generators

If you are going to buy a Generac generator, it should also be pointed out that different types are available. In this article, however, we will focus on two main types as discussed below.

Inverter Generators

These are more expensive compared to the second type we will be talking about later, which is because of having a more complex engine. They have sophisticated exhaust systems. This is a great way to reduce noise. It is also more efficient and produces lower emissions, which will make it a good option if you are concerned about your environmental impact.

Portable Generators

This is the category where the last three products belong. As the name implies, they are portable, which means that they are easy to bring anywhere. However, they are not as compact and lightweight as the inverter generators

While Generac is a trusted brand, this does not mean that you can pick just any model. Your budget and needs, among others, will dictate which one is the best option. If you cannot decide what to buy, below are some of their most notable generators.
