Very nice and works so well

[This review was collected as part of a promotion.] The photo shows it on its side because the wheels were being put on. However the wheels make it much easier to move around and the handle is even a better touch. The noise is not as loud as some I have heard and it was easy to start with the pull start. We plan to connect it to the house so it will run a few major appliances like the deep freezer and fridge.

Reliable, easy to operate, and so versatile!

[This review was collected as part of a promotion.] We own a cabin in North Carolina that was affected by hurricane Helene. Our power has gone out multiple times since and the Generac GP9500E Tri Fuel Generator is my new go-to source of confidence. What I appreciate most about this generator is its versatility. It can run on gas, propane, or natural gas, providing great flexibility when fuel options are limited. The maintenance process is straightforward, thanks to clear instructions, and LOVE the electric start. It makes it a breeze to operate. The COsenseĀ® safety feature adds an extra layer of peace of mind, knowing that it's equipped with advanced carbon monoxide detection. And with its 7.5-gallon fuel tank, this generator can provide over 10 hours of runtime at a moderate load. In conclusion, the Generac GP9500E Tri Fuel Generator is a wise investment for any household. With its impressive 12,500 starting watts and 9,500 running watts (when fueled by gas), it's more than powerful enough to keep our home running smoothly during an outage. Considering its size, the noise level is surprisingly reasonable and doesn't disrupt our daily lives. I'm incredibly grateful for this reliable and versatile generator.

Amazing power for the whole house!

[This review was collected as part of a promotion.] The GP9500E Tri-Fuel Portable Generator is an absolute powerhouse! I needed a reliable backup power solution for my home, and this generator exceeded all expectations. The ability to run on gasoline, propane, **and** natural gas gives me incredible flexibility, especially during extended outages. The 9,500 starting watts (7,500 running watts) provide more than enough power to keep my essentials running smoothly, including the fridge, AC, and even power tools when needed. The electric start is a game-changer—no more struggling with pull cords! Plus, the runtime is impressive, especially on propane. Build quality is solid, and the noise level is reasonable for its size. Setup was straightforward, and the included wheels make it easy to move around. If you're looking for a dependable, versatile generator, the GP9500E is worth every penny. Highly recommend!"* --- **Key Features Highlighted:** āœ… **Tri-Fuel Capability** (Gas/Propane/Natural Gas) āœ… **Powerful Performance** (9,500W starting, 7,500W running) āœ… **Electric Start** + Quiet Operation āœ… **Portable & Durable**

General Portable Generator

[This review was collected as part of a promotion.] Living in South Georgia, I need to be ready for hurricane season, and the Generac GP9500E Tri Fuel Generator gives me that confidence. With 12,500 starting watts and 9,500 running watts (on gas), it's powerful enough to keep our home running smoothly during an outage. I love that it runs on gas, propane, or natural gas—great flexibility when fuel options are limited. The maintenance is straightforward with clear instructions, and the electric start makes things easy. It's not whisper-quiet, but for a generator of this size, the noise level is very reasonable and not disruptive. The COsenseĀ® safety feature gives added peace of mind, and the 7.5-gallon tank provides over 10 hours of runtime at 50% load. This generator is a wise investment for any household facing severe weather. I'm so thankful for this.

For 50 hours then nothing

Bought this unit to get us through the storm last year. It did it's job well for the first 50 hours, then it quite running. It won't start and run. Pretty sure it's the electronics, the CO2 sensor. Saw a U tube video of the exact model doing the exact thing. Bad unnecessary CO2 sensor. So it sits there broken waiting for me to find a shop, time, and help to load it.

MUST Have for Homeowners! 5 Stars!

[This review was collected as part of a promotion.] I couldn't be happier with my Generac Power Systems GP5500 generator! Received just days before Nor'easter hit area and community power outage hit. This unit offers incredible value for its price, combining outstanding quality craftsmanship with durable materials that inspire confidence. Set-up was a breeze, and the ease of use is unbeatable! What really impresses me is how easily movable it is. The sturdy wheels make maneuvering it feel like pushing a wheelbarrow, which is a game-changer during power outages or when I need to relocate it for outdoor events. As a petite woman I am able to use and maneuver this unit like a pro, which is crucial in an emergency situation. It works perfectly, delivering reliable power whenever I need it. In short, the GP5500 is a fantastic generator that combines performance, portability, and impressive quality. Highly recommend it to anyone in the market for a dependable generator! Must have for any home owner!

Quality Generator

[This review was collected as part of a promotion.] The Generac 5500 generator was very simple and easy to put together. Adding oil and fuel easy as well. Start-up with manual startup was fairly easy. This unit also comes with a battery for an electric start which is pretty cool. The load can handle several small appliances such as a refrigerator, freezer and a TV or you can use it to run a single 220 volt HVAC system by itself. Moving the unit is a breeze as it comes with a handy handle that folds up and down for easy storage. Overall I highly recommend this unit and Generac is well known for their reliability and quality.

Dependable generator

[This review was collected as part of a promotion.] Took our new generator to deer camp this weekend and wow what an incredible generator. It is the perfect size for what we needed. Easy to move around and transport, not overly heavy. Is a dependable unit and had no issues at all. Easy to install parts for wheels, handle and legs. My 10yr old put it all together and filled it with the supplied oil. I highly recommend a generac system for all your needs. Generac even makes whole home systems for if you loose power. We will be looking into purchasing one of those for our home.

A must have on the farm for power outages! We will

[This review was collected as part of a promotion.] I am very pleased with the Generac Dual Fuel Generator. I gave it a try on my farm and it effortlessly powered anything I asked of it. Skill saws, lights, anything! It was easy to assemble. Propane took a minute to get started but gasoline fuel fired right up. The only reason I knock of one star is the difficulty we had starting it initially. Noise level is adequate for it's size. I couldn't imagine the farm without it. It also provides me comfort to know it's ready when needed for one of our many power outages!

Awesome well built generator!

[This review was collected as part of a promotion.] This is such an awesome generator!! Just the quality of it is immensely high quality. It is definitely heavy, it did take 3 people to get it up stairs. However, once the handle and wheels are installed it's much easier to handle and move. The controls are nice and not too complex once you read the instructions. Its fantastic for camping!
