Before buying, calculate the wattage requirements of your devices. Then, compare this to the output of the Generac GP3250. This will ensure you get a generator that meets your energy needs.

What Can’t It Power?

The Generac GP3250 is quite powerful for a portable generator. An output of 3,250 watts should be plenty for your camping trip or at-home power outage. However, please be careful not to plug in too many devices as it will burn out the engine.

Additionally, you should realize that this generator is not ideal for powering sensitive electronics. It has a total harmonic distortion (THD) of less than 20%. This is quite high and may cause damage to your phone, laptop, etc.

Here are some of the main reasons we love the Generac GP3250:

Small and Compact

The GP3250 weighs over 100 pounds. Yes, this is a little heavy for a portable generator.

But, its compact design makes it seem much smaller. It is tiny enough to fit into tight spaces and won’t take up too much room. This makes it the perfect size for tailgating, camping, and power tool use.

Portable Generator Generac GP3250

Aside from saving on storage space, this generator’s compact design makes it easy to transport. It isn’t too cumbersome and comes with a convenient folding handle. You can wheel it over pretty much any terrain thanks to the never-flat wheels.


Every part of this unit was designed with durability and strength in mind.

For instance, the never-flat wheels can withstand any terrain. They are built-to-last and will never need to be filled up.

The steel fuel tank is also very sturdy. Its strong construction and large capacity provide both durability and extended run times.

Hardened Steel Tube Cradle

For even more protection, the whole unit sits in a hardened steel tube cradle. This provides protection from the elements and ensures longevity.

High Output

Compared to similar products, the Generac GP3250 has a relatively high output (especially when considering the price). It is enough to power common household and outdoor appliances.

Large Steel Fuel Tank

The large steel fuel tank provides both durability and extended run times. It holds enough gas to operate for 9.7 hours at 50% load. This means you can go pretty much the whole day without having to refill.

Built-In Fuel Gauge

You’ll know when it’s time to refill thanks to the built-in fuel gauge. This will eliminate guesswork and help you stay on top of gas refills. The fuel gauge also lets you know when there is a low oil level.

Powerful and Efficient OHV Engine

The 206-cc OHV engine is just what you need in a portable generator. It provides plenty of wattage for the price you pay.

It also comes with plenty of safeguards. For instance, when it detects low oil, it will automatically shut down to protect the engine from damage.

The splash lubrication and a high-performance alternator are two other helpful features. They ensure smooth and efficient operation. Additionally, the four 120-volt outlets come with circuit-breaker protection. This ensures reliable performance by preventing the circuit breaker from overloading.


The GP3250 generator has plenty of perks. It is powerful, convenient, & provides durability and strength. However, the product has a few drawbacks that might concern you.

It’s Heavy

The GP3250 weighs over 100 pounds. While it is easy to wheel around, it is too heavy for one person to comfortably lift.

It’s Not Ideal for Sensitive Electronics

This generator has a THD of less than 20%. If we compare this to other products, we can see that this is relatively high. Too high, in fact, to safely power sensitive electronics. Please do not use this generator to charge your phones, laptops, etc.

It Doesn’t Have a Data Center

The GP3250 is relatively affordable. But, considering its price, we think it should at least come with an LED data center. Similar products have data centers that display important information like run time, watt output, etc.

It’s Not CARB-Compliant

The GP3250 is an EPA-compliant product. It also comes with a spark arrestor that makes it suitable for use in forests.

However, the generator is not CARB-compliant. In California, you cannot legally purchase generators that are not CARB-compliant. So, if you live in California, you should opt for a generator that is CARB-compliant.

It Only Runs on Gasoline

This portable generator is not a dual-fuel generator. It only runs on regular diesel.

If we compare it to dual-fuel products, we can see that it is not nearly as efficient. Models that operate on a combo of diesel and natural gas provide longer run times.

Customer Reviews

There aren’t many online reviews of this product. On, for instance, the product only has 20 global reviews. It does not have 5 stars mainly because of problems with shipping (oil spilled during transit, etc.).

When it comes to the generator’s functioning, however, most users give the product 5 stars on review sites. They tout it as the perfect size for tailgating, camping, and power tool use. They also like that it’s easy to use operate and claim that the price is more than fair.
