I'm 77 Years Old and I Unpacked and Assembled it By Myself!

My 17500E arrived and after helping the delivery associate get it up the driveway, I lifted the outer carton off the two, yes two, pallets on which it was bolted. First I removed the battery from its mount; and then placed a couple of furniture pads at the end of the pallet on the generator side (choose this because choosing the wrong end would place the generator weight on the electrical panel). Following that I pulled (jerked) the unit off the double pallets (save the bracket's & hardware) and let it glide off the pallets and onto it's frame. With little effort it pivoted up onto the end of the frame where I easily installed the wheels and the front leg assembly. That done I simply rotated it back to the ground, and was amazed that the balance of the unit actually helped bring it to a normal upright position. all that was left was install the handle, which by the way took Phillip's screw driver to hold alignment of the holes while the first one on each side was placed; and reinstall the battery. The reason I mentioned saving the pallet hardware will be evident as soon as you see them. I can imagine a million uses for the brackets down the road, and some of the bolts with locking nuts seemed to me to be a more robust choice for attaching the battery terminals than the ones' intended for the purpose. I can assure you that whining about the weight won't get the job done, but using one's brain makes an average afternoon's project out of the process.

Generac GP6500E TF Generator – Our Honest Experien

[This review was collected as part of a promotion.] We were fortunate to be selected as part of a Generac campaign and were given the opportunity to try out the Generac GP6500E TF generator. After putting it to the test, we can confidently say: this generator is absolutely outstanding! Watch my video you can hear the noise level. For such a large generator it’s not loud, loud! Compared to our old (small, little dude) DuroStar generator, the difference is incredible. See my side by side comparison of the two generators. The old one was unable to power our whole home. Mainly had it to keep the fridge on and perhaps a lamp. As you can see from the photos, the Generac is much more compact, yet it delivers so much more power and efficiency. It’s designed to handle major loads — from running a huge RV to keeping an entire home powered. In fact, we’re currently in the process of wiring our home to connect it directly, so during the next round of severe North Texas thunderstorms or tornado-related outages, we’ll be fully prepared. What truly impressed us: • Tri-Fuel Capability: The GP6500E TF runs on natural gas (NG), liquid propane (LP), or gasoline, giving us incredible flexibility depending on what resources are available during an emergency. Need different ways to be able to source power! • Reliable Startup: It starts up easily and quickly every time, which is critical when you’re dealing with unexpected power outages. As you can see just the push of a button. • Quality and Efficiency: Generac has a stellar reputation, and after experiencing this machine firsthand, we understand why. It’s thoughtfully engineered, highly efficient, and feels durable enough to last for years. • Easy Assembly: We had it fully set up in about 15 minutes. The instructions were clear, and we also watched a couple of their setup videos on YouTube, which were incredibly helpful. • Peace of Mind: With a young child at home, having dependable backup power isn’t just convenient — it’s essential. This generator gives us the confidence that we’ll stay powered and safe, even when the grid goes down. Our close friends down the road are gonna get one now! They came over and checked it out. They have kids too. So having power is important for them as well. Our power grids out here and very unreliable. One night all it took was someone hitting one pole in our town to knock out all the subdivisions power. Even though we didn’t purchase this unit ourselves, we would absolutely invest in Generac products in the future based on this experience. The GP6500E TF has exceeded our expectations in every way. We can now rest easy knowing that no matter how bad the weather gets, we’ll have the power we need to stay comfortable and safe. Love the solar options they have on their website! We’re campers so definitely gonna get one of those. I need to crockpot it in the forest!! Thank you, Generac, for selecting us to be part of this campaign and for delivering such an incredible, reliable product!

7500E Portable Generator

Excellent quality and great reputation is what led me to buy this generator. I am thankful I have not had to use it, however it provides a great piece of mind knowing its there if need be. One piece of advice I will give anyone purchasing a generator, secure your garage. My first generator was stole within the first two week of purchase. Since then we had anchors installed in the cement and have it chained down. We also have a place secured by the house if we ever need to use it that we can secure it to.

Beware it could be delivered with a defective battery

I purchased a GP8000E and paid extra for the electric start. I started it when it first arrived to ensure all was OK. It started right up. 8 weeks later I went to exercise it and the electric start would not work. I took it to a factory authorized service center where they discovered the battery was defective. It would not charge nor hold a charge. They replaced it and it started immediately and now runs fine. THE PROBLEM....This generator cost over a thousand dollars, is brand new with 12 minutes run time on it, YES 12 MINUTES. The generator was delivered to me with that defective battery and Generac WILL NOT COVER IT UNDER WARRANTY!! I cannot say enough good about ELECTRIC GENERATORS DIRECT which is who I purchased it from as they are a Generac Distributor. They stepped up BIG TIME once they were told what happened and THEY took care of this repair. Fabulous customer understanding and support by ELECTRIC GENERATORS DIRECT. Generac..not so much. This is a major purchase for most. Hope it runs and lasts longer than the factory supplied battery!

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:** ✅ **Tri-Fuel Capability** (Gas/Propane/Natural Gas) ✅ **Powerful Performance** (9,500W starting, 7,500W running) ✅ **Electric Start** + Quiet Operation ✅ **Portable & Durable**

Easy to Start

[This review was collected as part of a promotion.] This is my 3rd Generac portable generator not because the other ones went bad, but because we use all 3 as a service provider. These always start easily and provide the power we need at the various locations were landed power is not available. Fuel consumption is not the best, but you sacrifice using fuel for the amount of power you actually need. So my recommendation is don't oversize your generator to much for what you actually need.

Love the Simplicity

I wanted to get something to have as a backup to power our homes freezer and refrigerator along with a few small appliances. My main focus was simplicity. I need to make sure my wife could operate the unit while I was overseas and not needing to read an owners manual to operate it. Purchasing this product was a great decision and I am very satisfied with the whole package. It really is a peace of mind.

Awesome unit

I purchased this for my mom after the recent hurricane. She’s in her 70s with medical issues and this unit has made her comfortable in her home. It’s running 4 ceiling fans and three 110 ac units plus the house lighting and it’s not even straining at all. Thanks for a great product.

Great features

[This review was collected as part of a promotion.] We trust the Generac name. It was easy to assemble out of the box. Portability is great as it comes with never flat wheels. Fired right up and I am impressed with the quietness of the unit. I was expecting it to be much louder. Have only ran it a handful of times, but I have not came across any issues. We live in Tornado Alley and this will be a blessing during storms, however this is also great for job sites.
