Generac GP6500 generator overview

The manufacturing process of the Generac portable generator takes place in Whitewater, Wisconsin. It’s the first and the oldest headquarters of this company.

This 7683 model is a Generac 6500-watt portable generator. It comes powered by a 4-stroke 389cc Generac OHV engine with Splash lubrication.

Almost 90% of users recommend this Generac 6500-watt generator on Amazon. The most liked features were easy installation, expert support, overall performance, etc.

Overall it’s a suitable option for those who need a generator with a starting power of 8125 watts and 6500 running watts.

However, there are no USB outlets for safe charging your devices such as mobile, cameras, etc. This can be a bit troublesome for campers.

Let’s check this Generac portable generator specs…

Power Output And Tank Size

To find a suitable generator that fits all your backup power needs. You have to calculate wisely your power requirements.

Knowing the required power output will filter the long list of available generators helping you decide faster.

I suggest purchasing a generator with at least 20% more power than you need. Extra power will make sure your generator does not overload, thus saving the engine from damage. 

It will also be good to have some extra power for emergencies when extra power becomes lifesaving.

Running a generator at 80% – 90% of its max output also increases the generator’s engine life and performance.

This Generac 6500-watt  generator has impressive starting power of 8125 watts running on gasoline. With this starting capacity, you can start heavy power tools that use electric motors easily.

And, then running watts of 6500 watts is plenty to run all your household and heavy power tools. This Generac generator can also supply power at job sites, outdoor parties, etc.

But, still, if you need one with more power you might want to check the Generac 7676 GP8000E Portable Generator model. It has 8000 running watts and 10000 watts of starting power.

I used to think that having large tanks is better. But, soon I realized that it was not true. A large-capacity steel fuel tank means more runtime but, it also increases the generator’s weight and size. 

Due to more weight, the portability of the generator is also compromised. So, a balance is a must here.

This Generac 6500-watt generator has a large 7.9-gallon steel fuel tank. 

Efficiency And Fuel Type

Efficiency is a versatile term that’s used in different aspects. It primarily contributes to the overall performance of a generator. 

In simple words, an efficient generator has more power output and runtime hours for each gallon of fuel.

This Generac GP6500 portable generator has a 10.5-hour run-time at 50% load on a single tank of gasoline. When running on a quarter load i.e. 25% this generator can operate for 16.5 hours.

Dual-fuel technology allows users to run a generator with two fuel options. It can be gasoline or propane. 

Propane is cheaper and burns cleaner in comparison to gasoline. Dual-fuel portable generators become a good option if you don’t have either of the fuel options available. 

You can choose either type of fuel and run your portable generator during a power outage or any other emergency.

Generac 7683 GP6500 is a gas-powered generator and lacks dual-fuel technology. 

Safety Features

When using a portable generator, you need to look at many features. But, you should never neglect safety. 

By using safety measures, you can protect yourself and your family from any kind of accident. Especially accidents that occur due to power and dangerous emissions. 

All portable generators emit harmful gasses and substances by engine combustion. Hazardous Carbon Monoxide (CO) is one of these gases.

CO gets produced during combustion in scarcity of air. It is also known as a silent killer because it causes Carbon Monoxide poisoning. 

Features such as Covered power outlets ensure that the generator withstands bad weather. The Generac GP6500 comes with covered power outlets and a circuit breaker.

EPA and CARB are famous organizations that regulate the emissions from portable generators. EPA is the Environmental Protection Agency, and CARB is California Air Resource Board. 

All the generators have to be compliant with either of these organizations. CARB compliance is mandatory to sell a portable generator in California. 

Generac GP6500 generator is CARB and EPA compliant. This generator is available for purchase in all 50 states.

However, if you are not in California you can save more than 100 bucks by buying the 49 St. version. 

Generac 7680 GP6500 Portable Generator has 49 state configuration and is available at a lower price.



This CARB-compliant model also has COsense® Technology that can save you from any accidents because by Carbon Monoxide buildup. 

It detects dangerous levels of Carbon Monoxide and turns off the engine immediately. So, COsense® is must-have protection against hazardous CO gas.

Quiet Operation

We all can agree that no one is a fan of noisy generators. But, looking for a quiet generator with zero noise is not possible.

It’s because all the generators produce some level of noise which can be either high or low. 

A loud generator can attract attention and complaints from neighbors. No one likes this and has zero energy for this purpose. 

You will never like having a generator that produces a lot of noise. That’s why you should use one that produces less noise. 

If you plan to use a portable generator during camping, a lower noise level is necessary. 

The Generac GP6500 portable model produces a noise level of 75 DB. This generator has an open engine so it is a bit loud. It will sound like a lawn mower running outside.

This noise level can bother you if you are looking for a quiet portable generator. But, keeping it at a distance will solve this issue.

Durability And Portability

The durability of a portable generator refers to its ability and strength to work under extreme conditions and its life hours. 

A lot of features combine and increase the overall durability of the generator. 

Overload protection protects generators from major engine damage by overload conditions and thus increases generator life.

Low oil level Shutdown in Generac GP6500 shuts down the engine when the oil level gets low. This low oil feature saves the generator engine from incurring damage by running on low fuel.

This Generac GP6500 generator has a hardened steel-tube cradle. It contributes to the strength and durability of the generator. 

It is a heavy generator that weighs 172 pounds. It is heavy and you won’t like moving it on difficult terrain even with heavy-duty wheels on it.

But, the portability improves because of the wheel kit with heavy-duty, never-flat wheels. It also has a fold-down handle. The folding handle and wheel kit ensures sturdy portability and compact storage

Weight: 172 lbs

Dimensions: 27.2 x 27 x 26.5 inches

Generac GP6500 generator comes with a 3-year residential/1-year commercial Price and expert customer service.

Convenience

Generator manufacturers try to add a lot of unique features to stand out. Some of them weren’t able to make up to the bulleted points but are an important addition to generator features.

Let’s look at some of the amazing features of the Generac 6500-watt generator.

PowerRush™ Advanced Technology

With PowerRush™ Advanced Technology Generac GP6500 can produce 40% extra starting power i.e. 8125 watts.

This increase in power increases the range of tools and appliances that can run with a power supply from Generac GP6500.

HomeLink™

HomeLink™ is compatible with a manual transfer switch. This enables you to start using this generator for portable power almost immediately after the initial setup.

Control Panel

The control panel does an Hour Meter display. An hour meter helps you track maintenance intervals. Maintainance after some periods of time increases engine life.

Generac GP6500 comes with a 120/240V 30A (L14-30R) Twist-Lock Receptacle and two 120V 20A 5-20R Duplex Outlets.

It also has circuit breakers and covered outlets for added safety. 

Recoil Starter

This generator has only a recoil start, which is not difficult to use. But, an electric start generator is much more convenient and easy to use. 

If you don’t want a recoil start generator and are looking for an electrical or push start generator. Then don’t hesitate to check the Electric start model of the same generator.

Generac 7682 GP6500E Portable Generator has the same features but has added an electric start feature. However, it is available only in 49 states other than California.

You might also want to check the Generac store on Amazon for other Generac portable generators with more options and features.
