What To Consider When Buying A Generac  Portable Generator

Generac generators are very popular in the market. That is because they offer a great deal of value for money and can be used in various environments.

Generac portable generators are environmentally friendly because of their superior fuel efficiency, reducing carbon dioxide emissions. 

 If you have been looking to buy a Generac portable generator, here are some of the factors that you should consider before buying one:

Capacity and Wattage

First and foremost is the size and wattage of your generator. You want to make sure that it can provide enough power to run all your appliances at once.

A GP3000i model will be enough for most homes with five bedrooms or less, but consider other models if you need something bigger (or smaller) than that

 Choosing a generator big enough for your needs is essential but not too large to unnecessarily burden your finances and energy usage. 

Power Output 

You need to make sure that your generator has enough power for your different needs. How many appliances and devices you want to run using your portable champion generator will determine this. 

The more appliances and devices, the greater power output it will require from the generator. Generators with over 5000W are recommended for heavier appliances.

Maintenance Costs

While Generac portable generators are designed to provide backup power during outages, they can also help reduce energy costs by running during off-peak hours. 

That’s because most Generac models feature an Eco Mode switch that allows them to run several hours at a time without overheating or draining your wallet.

Frequency Of Use 

This is probably the most important factor to consider. If you’re only going to use your generator once or twice a year, then there is no need to pay for extra features that you will never use.

A simple 2000W Generac portal generator would be enough for you. Ultimately, any portable power system will need to perform under a wide range of conditions and workloads.

Inverter Vs. Non-inverter Generators

There is a huge difference between an inverter generator and a standard generator. Inverter generators produce clean power with a frequency of 60 hertz instead of 50 hertz, which means they can be used on any electrical equipment without damaging it.

 In addition, being lighter in weight than traditional models, inverter generators also consume less fuel for producing energy than the other types of generators available in the market today.

Surge Power Vs. Running Watts 

Surge Power is the number of watts that can be generated for a short period during an emergency. At the same time, running wattage indicates the amount of power that your unit can continuously generate. 

It is important to note that most generators can switch from Surge power to Running power and vice versa. 

Fuel Source 

Generac portable generators can be powered by propane, natural gas, diesel fuel, or gasoline. It's crucial to understand the fuel compatibility with your Generac generator. 

This will ensure that you never run out of fuel while also giving you more flexibility regarding using your Generators.

Fuel Efficiency 

The priority should be 'fuel efficiency' because the cost of operating these machines can get high if they are not efficient enough.

 Make sure you choose one with minimum fuel consumption (0.5 gallons per hour) and how long it takes to charge up if this is an essential factor for you.

Noise level

A quiet Generac portable generator with low noise will not disturb your peace when used, but it will still be powerful enough to do what you want. 

This is especially important when using a portable generator in an urban setting where noise could become a problem at night when everyone is trying to sleep, such as in a park or campground with neighbors nearby. 

Larger generators with 3000W and above are noisy but very reliable.

Weight Of The Generator (In Pounds) 

The weight of a generator is usually measured in pounds, but it depends on the manufacturer. It is important to note that most portable generators weigh 100 pounds or less (when empty). The average weight ranges between 50 and 75 pounds.

 If you want to buy a portable generator with wheels, look for one that weighs about 70 pounds at most. Otherwise, it will be too difficult to move around.


The Generac portable generator is a good choice for those who want a portable generator that can be used for small outages and recreational purposes. 

This generator provides all the necessary power you need to start up your appliances and should handle any emergency without an issue.

We hope you find this guide helpful and hope it will help you decide which generator is right for your needs.
