Generac GP8000e Review

Power

One of the most essential things to bear in mind when buying any generator is how much power it offers; after all, what good a generator is if it doesn’t deliver the amount of power that is required.

Think of what you intend to do with the generator you’re buying. If you want to power your RV, camp appliances, or home appliances, you should always look for a generator that provides enough watts to achieve all that. 

Though it’s quite challenging for a single portable generator to achieve all this, the Generac GP8000e is an exception!

With an uninterrupted 8000 watts running power and 1000 watts starting power, this generator offers an impressive ability to run heavy-duty appliances.  

What Will 8000 Watt Generator Run? 

With a running power of 8000 wattages, you can run many different things efficiently. 

For homeowners, it can work as a significant power backup and can run a majority of household appliances such as air conditioner, fridges, lights, oven, water heater, pump, alongside sensitive equipment like computers, laptops, tablets, etc. 

Apart from using the unit as a backup power source during power outages or emergencies, you can also use it in several other things like recreational activities (tailgating, RVing, etc.), farm equipment, and industrial equipment. 

Thus, with the Generac GP8000e, you can not only power your house in case of emergency but also use it to power RV, tailgating equipment, and construction power tools.    

Fuel Efficiency

Like many Generac portable generators, the GP8000e is also designed with a very upfront approach for running. The unit relies on standard gasoline for fuel, unlike many other similar models that use propane as their fuel-type. 

Since the unit runs on gas, which is readily available, you won’t have to disrupt your work or other things in case of a fuel shortage. Plus, it’s one of the most affordable fuel-type options. 

This Generac gas-powered model includes a 420cc OHV engine capable of generating about 8000 watts peak and 10000 watts maximum power, mainly because the generator comprises a Power-Rush technology that enables it to accelerate its starting watts by 30%. 

Its steel tank can hold about 7.5 gallons of fuel, which is more than adequate to keep this electric-start generator continuously running for up to 12-hours at half load (50%). 

In addition to that, the average fuel consumption of the unit is approximately 0.79 gallons/hour. This makes GP8000e the most fuel efficient generator in the entire GP series. 

Moreover, thanks to the GFCI outlet of this unit, this generator is transfer switch ready. This means you can power your house by effortlessly connecting it with the house circuit breaker.
