Great Portable Generator

A portable yet powerful generator that is well suited for home backup power needs. Wheels and collapsable handle make it easy to manuver. Electric start makes it a snap to fire up. Enough output to protect freezers and fridgerators. 240VAC has enough output to power a well pump.

Reliable, well built, delivers when needed, keeps us safe

The GP8000E Generac Portable Generator is the first generator we have acquired. Its no nonsense starting instructions make it easy to start the generator. We read through the instructions completely and started it same day we purchased to validate reliability and our know-how and it started immediately and safely. Instructions are easy to understand and follow. We look forward to having it up and ready to go whenever we may need it. Safety directions are clear and thorough.

Proud owner

Easy to assemble well explained instructions. You can see and feel you have a solid well built piece of equipment. Started without issue however was louder than anticipated or had hoped for. Peace of mind knowing that my family will be comfortable through power outages thanks to Generac

The big beast GP17500E

Haven't had a chance to run the house with it yet, but I'm sure it will make light work of it with no problem! The overall quality and appearance of this machine is very well put together. The only issue I had is that it took over 4 months to get it...I'm guessing it's probably production run intervals.

Plenty of power and love the electric start.

Very easy to setup, had the house on backup within minutes of receiving the unit and it runs everything we need with power to spare. 10 circuits including fridge/freezer. well pump, boiler, lights, , microwave, kettle, toaster, home theater and office...!

4 out of 5 stars review

I bought this during hurricane season since my other generator did not put out power anymore,it started great but shut down 15 min. later, I can restart it, but it kept shutting off every few minutes. The CO2 sensor is just too sensitive. You can’t have it near anything pretty much out in the open. It’s kinda hard when it’s raining and you can’t even run it under a tarp other than that, I guess it’s a good machine. Hopefully it will start up for me next Hurricane season, I would give it a five star if there is a way to disconnect that CO2 sensor and not void warranty

This generator was a God send

My house caught fire and was unlivable. But we had 2 freezers with LOTS of food in them. I bought this model generator, at a reasonable price, to keep my freezers running until I could get my house livable again. It’s the perfect size and wattage for me, affordable and it runs for ever on a tank of gas. Thank you Generac!!

So far, so good. We'll see as time passes. Electrician recommended.

One minor part (battery wire terminal boot cover) missing from shipment that did not affect assembly nor operation so far. Will call Generac to get the part. Unit started immediately after assembly with no problem. Putting the feet and wheels on is NOT a one-man job without a jacking device or something to lever the unit. The issue is likely common to all brands. Connecting the battery terminals requires care to avoid shock. It would be better if the terminals were separated lengthwise on the battery, as opposed to both being along a "short" side, as presently configured. Oil fill is a pain, as it is on most small engines today. "Quality" is not only the power, but the long-term reliability. I have no reason to expect the unit will not last for years, but the short warranty period (all brands are the same) gives pause. Ask me again in 5 or 10 years and "average" could become "excellent".

DeWalt 6500 Series

My review is based on the DeWalt 6500 made by Generac. DeWalt a name that is associated with quality products. No matter if it's tools or a generator. DeWalt is a name that is synonymous in the industry for quality. This generator is made by Generac for Dewalt which also is a name that is synonymous in the power generator industry for reliable generators. The bigger the watts on the generator usage, the longer run time at 50% power before refueling. In other words if you run the generator at half load (in this particular case 2 divided into 6500 watts = 3250 watts) you will decrease the fuel consumption by about half. The generator will not have to run at maximum speed to produce a continuous 6500 watts. That is why if you plan on purchasing a generator, always purchase a bigger generator in terms of wattage than you will need. This will decrease your fuel consumption by the generator and you'll be able to run for an extended period of time on the same amount of fuel. Living in South Louisiana along the Gulf Coast, we experience hurricanes often.This generator will allow me the peace of mind knowing that the size of this DeWalt generator will allow me to know that this generator will meet my most critical needs after my power has been knocked out and knowing that the DeWalt name is behind this generator. This generator will allow me to keep my refrigerator and freezer (packed with seafood) continually working and keeping my family comfortable in the hot and humid Louisiana weather. One thing to remember, when using a generator, plug-in one appliance at a time to keep the generator from spiking. All appliances have a capacitor which kicks in when first starting the appliance. This draws quite a bit of wattage from the generator. The capacitor is used to to start the unit and once the unit is up and running the capacitor will disengage and the unit will be running normal. Once this is accomplished the next appliance can be plugged into the generator outlet. Repeat the procedure for the next appliance. This procedure will keep the generator from spiking and shutting down. This DeWalt generator is packed with many features that makes it practical and versitly for a portable generator. DeWalt uses two words to define their array of products "GUARANTEED TOUGH" and that is the truth!

Well made, easy to use

[This review was collected as part of a promotion.] The Generac generator arrived in a large box and was pre-assembled. The product is bright orange making it easy to spot in our unorganized garage. It was easy to use and instructions were simple. I would recommend everyone has a generator in their home in the event of emergency or prolonged power outage. This would easily power our freezer/refrigerator. It is also compact enough that you could take it camping or to an outdoor event. The only small complaint would be with regard to packaging. As we all know, items shipped get banged around and my generator had a small crack in the outer plastic casing. It was nothing that prevented it from working properly but if it was shipped further perhaps more damage would have been done so I would suggest more padded materials inside the box.
