Generac Gp6500 review

You must set up your mind to buy a Generac GP6500 generator, right? We assume you are just a little confused about the quality. No worry. Here we are. 

In this review of the Generac gp6500, we will tell you every single feature and ability of this generator and also we will give you some alternatives so that you can compare and decide by yourself. So let’s get started.

Power Output & Run Time

our Generac Gp6500  as a home backup

The Generac 5975 GP6500 generator featured a 389cc OHV engine, a highly efficient and long-lasting fuel tank, and a sturdy steel frame.

Its OHV engine runs with the common fuel type: gasoline and produces 5500 watts of pure energy, with a starting watt of 6,875w.

That is more than enough to run an RV (recreational vehicle) or provide backup power to your residence for almost 10 consecutive hours.

Let’s compare the run time, weight, and backup power. Compared to the other portable generators, the Generac portable generator has a lot of backup power, and you can use it during a power outage.

The fuel tank contains 7.2 gallons of gasoline volume, which provides backup power for up to 10 hours on a 50% load, making it the most long-lasting portable generator of this particular brand that we are looking for.

Indeed, if you decide to buy the more expensive and higher-powered model from the GP range, you’ll get longer run times. But for a generator of this particular size, it’s praiseworthy that it can generate a huge power in 10 hours with just 50% load.

Again, 6,875 starting watts is amazingly impressive for a generator of this budget cost. Generac GP6500 portable generator avoids overload with the pull start-up requirements of an electric start more like it starts on the first pull manually.

Even though this generator is a little bit noisy, it still runs at around 71 decibels of sound level, making it one of the louder generators we selected from this brand.

The loudest one was only two decibels higher than this. You will still be able to hear the conversations over its sound, especially if you are not standing too close while it’s running, but probably it’s not the best option to take it camping.


One of the most attractive features of this powerful portable generator is that you can hook things up to it. You will not get any DC outlet here.

Don’t worry; you will have four standard outlets (120 volts, 20 amp) and also a single industrial locking outlet (120 volts, 30 amp) for easy usage.

Undoubtedly that will be enough for most people’s necessities. These five circuit breaker-protected outlets are covered to avoid damage.


extremely portable Generac Gp6500

The compact storage feature of Generac GP5500 is another outstanding breakthrough. It’s also sturdy and long-lasting.

The generator has a strong steel frame, making it resistant to damage and well-decorated for heavy-duty use.

Keep in mind that it is fairly heavy, weighing up to 171 pounds. That’s a little bit heavier than the other generators of the same category with an average of 178.5 pounds.

However, it is easily portable. Thanks to its 9.5-inch never-flat wheels and foldable handle.

Features That Got Us Hooked

PowerRush Advanced Technology

Generac’s PowerRush Advanced Technology increases initial capacity so you can accomplish more with fewer resources. It offers up to 50% more starting power than typical generators, enabling you to run heavy equipment and appliances easily.

Easy Electric Start

With just the push of a button, the generator can get started quickly and easily.


Generac’s Quiet-Test feature briefly runs the generator once a week to make sure it will be ready when you need it. The generator is also significantly quieter than conventional generators thanks to this functionality.

The Advanced inverter technology and enclosure design offer the quietest performance possible. Generac generators are said to be the quieter generators but Generac can win the game in terms of noise.

LED Display

One of the coolest features this model offers is its vivid LED display. On display, there is a fuel gauge so that you can see how much fuel you’ve used and how much you have left. 

The LCD display screen is attractive and allows you to cycle through the generator status – engine hour meter, fuel level, predicted remaining runtime, and watts output.

It makes monitoring more accessible and easy by allowing you to switch between three different modes (Turbo, Standard, and Economy). And the vivid screen is easy to read; it’s perfect for professional use.

Automatic Transfer Switch

With the help of its control panel, you can alternate between manual and automatic generator operations. A built-in hour meter and automatic shutdown safeguard are also included.

Easy To Maintain

With regular standard servicing, the Generac GP6500 can last for years. It comes with a comprehensive user manual, helpful instructions, and information that makes maintenance pretty easy.

A generator is an excellent option for people wishing to lessen their influence on the environment because it creates fewer pollutants than other generators of comparable size.

The generator is very simple to maintain and needs little upkeep to continue operating well.


One of the biggest reasons for being our top choice of a portable generator is its price. Compared to the other portable generators, the power, and utility you get from the Generac 7683 GP6500 are exceptionally outstanding.

It costs around $950+ if you purchase it directly from Generac dealers. However, if you want to get it from a retail company like Home Depot, Amazon, or Walmart, you can get it at a discount of almost $900+.

Even though there are more suitable options available, some come with more convenient features; some are more portable, but you’ll be paying over $2,000 extra to get them. Costing below $1,000, the service you get from Generac GP6500 is exceptionally great.

Warranty Information

In a few words, Champion Power 75531i has outstanding features like being Lightweight, ultra-portability, and much quieter to run than other generators, this is the perfect generator you will want if you’re a camp lover.

At last, comes the Pulsar PG7000W generator. This is an excellent diesel generator for homes or offices. It generates up to 5,500 running watts and is able to power everything from campers to household appliances.

It’s heavier but runs longer than many gas-powered generators. If you are looking for a powerful generator it can be your other choice.
