Works well; good warranty

I bought this product brand new after our home was impacted by Hurricane Helene. The generator worked great, but the fuel gauge was defective, causing a lot of undue stress and complications. It has since been fixed under warranty, but it was not something I thought I would have to deal with.

Poor Quality

I was really surprised at the poor quality of the generator I purchased in the aftermath of Hurricane Helene. The fuel tank leaked fuel. Once I got the tank replaced, the fuel petcock now leaks fuel. Even the replacement one I received leaks fuel. I would not purchase again, nor would I recommend purchase of a generac generator.

Solid and effective investment that's dependable and durable

With multiple power outages that lasted for a week or more, this generator has been one of the best preventative investments I have done. Originally purchased for household power back-up purposes to prevent basement flooding sump pump needs, it has provided ample coverage for other basics - freezer, refrigerator, heat and hot water. Easy to start and maintain with minimal effort. Simple switchover capabilities.

No power :(

Well, I bought this a couple years ago to use when we go camping. I used it once and had no issues. Today I got it out to power my furnace in the house. None of the outlets have power. I checked the breakers and no luck. I tried the GFCI, but it won’t trip because of no power.

Great Generator

Purchased the gp6500 after a lot of research. It offered the best power for the price. We only had to use it for a little over 1 hour for the first 7 months we owned it. We have been faithful in starting it about every other week or so and ran it with a load for about 20 minutes. We have kept the tank full of gas treated with stabilizer. Well sure enough we lost power this week do to freak March snowstorm. Started on the second pull. It ran over the course of three days for 29 hours. Worked flawlessly. Really a lifesaver, especially with three kids and the wife. Ran 3/4 of the entire house including a well pump, two refrigerators and a deep freezer. We have a Woodstove in the basement so no need for it to run a heat source. Bottom line... Awesome product, great value and so far seems durable. If you're debating this generator, go for it!!!!

One of the best Generators out there!

[This review was collected as part of a promotion.] This portable generator by Generac is exactly what you need for camping, power outages, or basically whatever diy project. It's tri fuel which makes it convenient and it's not very loud so it won't disturb your neighbors!

A Life-Saver!!!

[This review was collected as part of a promotion.] We’ve lost power four times this summer due to intense Philly storms, and I can honestly say the Generac Tri-Fuel Portable Generator 50ST came in clutch every single time. Setup was straightforward, and the tri-fuel option (gasoline, propane, or natural gas) gave us flexibility depending on what we had on hand. We mostly ran it on propane, and it powered everything we needed — fridge, lights, fans, and even the Wi-Fi — without breaking a sweat. The runtime is solid, and the peace of mind it gave us during outages was worth every penny. It’s not the lightest piece of equipment, but it’s built to last and easy to move with the wheels. Noise level is totally manageable for a unit this powerful. If you live in an area prone to storms or unreliable power, this generator is an absolute game-changer. After this summer, I wouldn’t be without it.

Runs when you need it!!

Bought this to replace an older one I gave to my son, ran like a champ for years. The new one was purchased because of the Deracho that went through our area Benton Co. Iowa, August 10, 2020. Finally found one 75 miles away in Cedar Falls. First oil change 41hrs, second change at 109 hrs. The unit ran continuous for 187 hrs. straight! One pull start every time. The unit ran our 28,00 sq. ft. home, AC, frig, freezer, lights etc. Excellent piece of equipment and reliable! Never been happier. Thanks, Lee

Great Product

So I heard Generac has a great reputation for making reliable generators and even though I bought a portable generator, working in the propane business, their are many where I live that are buying the permanent home stand by propane powered generators and they are reliable and even though my is portable but used for home standby too, its what I want. I know it will do the job and keep us comfortable and our keep our food fresh while the power is out. I have yet to get my electrical panel up to code and a transfer switch installed on my house, but when I do I will be able to enjoy the full luxuries of having power without power :) Noise level though its just like a lawn mower or any other gas powered engine, pretty noisy, but again, your inside and its outside and so i can handle the noise.

Works great right out of the box

I was amazed on easy everything was and how well it was all explained. Setup took less than 10 minutes and you just have to fill with the oil supplied and fill with gas. Getting the gas took the longest time of the whole setup process. Started on the first pull and ran like a champ. It runs quiet and and with very little vibration. I purchased this unit because I am sick out power outages and this is the best investment made for that problem. It will run everything that is needed when your power goes out, to get you by without damage to your home or your pocketbook. Best Investment I ever made, don't know what took me so long to get one!
