Features and Functions

Generator on Wheels

The heavy-duty, never-flat wheels featured with the Generac GP8000E make it great for portability without sacrificing any of the 8, 000-watt power provided. This gas-powered portable generator packs a serious punch, which makes its portability a highly appealing feature. However, it isn’t quite as small as your average gas-powered portable generator.

It doesn’t come with an easy-carry handle like some other models. It weighs in at 197lbs, so unless you’re trying to get some unique body-building in then you won’t be carrying it anywhere. Given the power this generator produces, however, this should be expected. The Generac GP8000E isn’t designed with smartphones or televisions in mind. It’s a heavy-duty gas-powered electric generator, so it’s built like one.

Large Capacity Steel Fuel Tank

The large capacity steel fuel tank featured with the Generac GP8000E can hold up to 7.5 gallons. This is a much higher capacity than your average gas-powered portable generator so provides a long engine life. It’s fueled entirely by gasoline, which may be a drawback for some buyers who prefer a variety of fuel options. Still, even with gasoline as your only option, it’s an impressive tank.

To give you some perspective, a 7.5-gallon fuel gauge will power your house appliances or equipment with a run time of up to twelve hours. That’s an impressive duration for any generator. If you experience a blackout or just need an extra boost for your RV when exploring uncharted territory, the Generac GP8000E has you covered.

High Wattage Performance

This electric start gas powered portable generator packs a punch with the 8, 000-watt starting capacity allowing you to stay connected for longer. With 10, 000 starting watts, the Generac GP series 8000E offers up to 30 % more starting capacity than competing portable generators. This is thanks to the unique PowerRush advanced technology associated with the GP8000E.

In addition, the 8,000 running watts can power all of your home essentials when required with a run time of up to 12 hours. This includes your freezer, stove, lighting, and air conditioning. ThisĀ  generator is also considered one of the best furnace generators to keep your home warm.

Running watts of 8, 000 is a big win for many consumers due to its capacity to keep your household running. A blackout isn’t ideal for anybody. You don’t realize how much you depend on flowing electricity until it’s gone. The Generac GP 8000E keeps you connected when you need it most. The Generac GP series also increases electrical current upon demand above rated output when necessary.

It needs checkups to ensure it remains safe to use. Generac makes this easier to keep track of thanks to the handy meter provided.

Handle that Locks For Portability and Storage

Despite the size and weight of the Generac GP8000E, it is not as clunky as you might imagine. Simply use the fold-down locking handle beside the steel tube cradle and you instantly have a more compact generator. It’s easy to store away despite its appearance, which makes it perfect for those emergency situations. It’s right where you need it when you need it, but isn’t an eye-sore in the home.

Safety is Key: Automatic Voltage Regulation and Low Oil Level Shutdown

There are two primary safety concerns featured with any generator: voltage regulation and low oil shutdown. Generac delivers on both The low oil shutdown automatically safeguards engine function from overheating or overloading. The voltage regulation means the constant flow of running watts won’t short circuit any of your appliances. It only supplies the power required, unless manually directed to do otherwise. The OHV engine with splash lubrication provides you with a generator that will last.

Low oil level shutdown automatically safeguards your generator from undue damage. Covered outlets also add a layer of protection if you decide to use the generator outdoors. There are five covered outlets in total so you are fully protected. The hour meter helps you keep track of service requirements. The Generac GP8000E is also fully OSHA, EPA, and CARB compliant, making it the industry standard for safety features.

What do Previous Customers Have to Say About the Generac GP8000E?

Generally speaking, the customer reviews of the GP8000E are overwhelmingly positive. You can’t tell everything from a customer rating, we appreciate that, but you can gain some much-needed insight when necessary. We’ve looked through what previous buyers have had to say about the GP8000E and compiled some common threads we noticed.

As we said, most of the reviews are highly positive. There is specific appreciation given to how simple the generator is to use. Provided you have the gasoline to fuel it, the GP8000E is quick to set up thanks to the electric start push button. Many users reported keeping the generator in their garage or similar storage space as a reliable backup for when power outages strike. Blackouts are always unpredictable, but with the right generator, they needn’t be so stressful.

Other reviews highlight how quiet the GP8000E is in comparison to similarly-sized generators. The GP8000E measures in at 70DB, so it isn’t exactly silent, but for a generator, with so much wattage it’s still impressive. For reference, 70DB can roughly be compared to the sound of conversation in a restaurant or office. This is quite a noisy generator, but you aren’t purchasing it to sound pretty. It serves a powerful function, and performs it well!

Negative reviews are far fewer than positive. However, we should still mention them. Some common concerns we picked up on mainly related to temperature, as odd as that may sound. Certain users reported that the OHV engine did not perform as well in colder climates and sometimes failed to start entirely. As far as we read, this is not a universal experience, but it is something you should consider if you live in a colder area.
