Very importantly, there is an hour meter to track the voltage, frequency and hours of operation. Therefore, it is easy to monitor the generator's internal working and schedule proper maintenance.

When it comes to construction, the steel-made fuel tank is equipped with a fuel gauge. So, you can read the fuel levels and refill the tank before it empties. Plus, you can extend the runtime by switching the generator to a smart eco-mode.

A low oil shutoff system will stop the engine operation when the oil level is low. Hence, you can prevent the whole unit from overheating. All the power outlets have rubber cap protection to prevent any damages due to bad weather conditions. This generator comes with a pair of heavy-duty wheels and foldable handlebars for easy transportation.

A detailed review of Generac gp6500W generator

The Generac GP6500 generator is known for its versatile performance. You can do a lot with an output wattage of 6500W. Unlike other traditional generators, this generator comes with a CO sensor to protect the unit from excessive CO built-up.

 Power Output

Generac GP6500 is equipped with a powerful 389cc OHV engine. It can deliver a continuous wattage of 6500W and a peak wattage of 8125W. Very importantly, this generator comes with a PowerRush Advanced Technology to boost the peak wattage by 40%.

The biggest question that arises in your mind is the necessity of additional power. With an output power of 6500W, you can run all the essential devices like TV, refrigerator, lights and fans. Plus, you can make use of the leftover power for powering heavy amperage appliances like air conditioners. But if you plan to run whole house appliances, you will run out of power. At that time, you can utilize this extra starting power of 8125W

 Runtime and tank capacity 

Although the tank capacity remains the same, there are ups and downs in the runtime. Runtime decreases with an increase in connected loads. You might wonder why that happens. Yes, runtime truly depends on the applied loads. At an applied 25% load, the runtime is about 16.5 hours. But, the runtime decreases up to 5 hours (11.5) at 50% applied loads.

Very importantly, this generator comes with a smart eco-mode. You can utilize the fuel efficiently, thereby extending the runtime.

 Noise ratings 

So far, there is no standard test for estimating the noise level. Till date, the noise level is calculated based on the load connected to the unit. At 3feet, the noise level is about 90 decibels at idle conditions. With an increase in distance, the noise level is up to 76 decibels at no load.

In fact, the noise level increases with an increase in applied loads. At 50% applied load, the noise level is about 81 decibels at 20ft. In a similar way, the noise level is about 89 decibels at full load conditions. Although it is an open frame generator, you can install noise mufflers to reduce noise.

 Power panel and connections

On the side of the generator, you can see a control panel. It consists of an ON/OFF switch, circuit breaker, hour meter and a CO sensor. The power outlets like 2x120V 20A 5-20R GFCI duplex outlets and one 120/240V 30A Twist lock are sufficient to connect multiple devices simultaneously. In addition, these outlets come with rubber caps to protect the outlets from freezing during the winter season.

There is an hour meter to track the important parameters like voltage, frequency and hours of operation. So, you can monitor the generator's working mechanism and schedule proper maintenance. There is a fuel gauge to indicate the fuel levels. Therefore, you can read out the fuel levels and store the fuel in advance. Apart from this, a low oil shutoff system stops the engine operation when the oil level is low. So, you can protect the engine from overheating.


This generator comes with a separate wheel kit. So, you can attach the 9 ½-inch heavy-duty wheels and foldable handlebars for easy transportations. These durable wheels will not deteriorate when dragged on rugged surfaces.


With many advanced features, this generator's price is around $799. It is quite reasonably priced because it features a CO sensor. Moreover, it comes with a warranty of three years. In short, it is a bang for your buck.


Final words 

Generac gp6500 generator can be the lifesaver during emergencies. A full tank offers incredible runtime. So, you can manage without power for more than two days. Plus, the PowerRush technology will provide additional starting watts to run electrical appliances. The highlight of this generator is the CO sensor. So, this generator is eco-friendly and user-friendly.
