Very pleased!

This is a powerful unit that will meet our needs during an outage. For us, it will power the heat strips on the furnace, our water pump, the refrigerator, microwave and enough lights to see our way through. We are very happy with our purchase and as we always say...we hope we never have to use it!

First Impession not good, Sence then perfect

Bought this generator as a home back up. First use was a long term power outage in cold weather. After 17 hours it pushed the little gasket/bushing out of a fitting where the two wires go through the crank case for the low oil sensor, It puked all the oil out of it on my driveway until the low oil sensor shut it off. Not good at 2am in 5 degree weather. In the dark I thought it blew up with all the oil. Diagnosed it the next day, pushed the bushing back in place with silicone sealant. Sense then it's been perfect. I like the generator now but at 2am the first use I was frustrated. I would still recommend this generator as I think this was a fluke and it's been perfect since

The Product has what I need

I have only owned this product for a short time but it powers my furnace, sump, fridge & freezer. I have not pushed it any further but that's the coverage I need if I get in trouble. However; I would like to have some one tell me how to replace the muffler. I want a very portable & quiet power source!!!

Awesome looking machine!

I just received my Generac GP8000E portable generator a couple of days ago. I bought it for the sole purpose of having back-up power in case of a power outage. I asked our electricians at work which generator they would recommend and they both said this one at the same time. That tells me a lot. We have a Generac stand alone at work that powers our whole office and I feel that if they both recommended this model and brand, then it must be the one I'll be happy with. I'm almost hoping the power goes off this winter..... lol

Easy to use / Easy to set up

I had been looking at a generator for awhile and contemplated many different brands. For the price, wattage and most importantly, name brand quality, I found that Generac was the way to go. Spend the money and get the electric start. Save yourself the aggravation at using a pull start. Just push a button and rock n' roll. Upon first unboxing it, everything was zip tied together very neatly and it was well packaged. It wasn't so overdone that you spend hours cutting away zip ties like you do with your kids toys on Christmas morning. Cut a few of the zip ties and you are ready to connect the batter cables. The generator was SUPER easy to get set up. If you can use a wrench or socket set, then you are good to go. You don't have to be super handy at all to do it. The directions were very simple and easy to follow. A matter of securing the wheels to the frame with the axle and washers (Provided) and also securing the pulling handle to the frame. Other than connecting these bolts and two very small bolts for the batter connection, it was a snap and took only minutes to unbox and be fully ready to use. The generator comes with an initial package of oil and it's a matter of opening up the oil valve and pouring it in. Heck, I can do that. This unit is very heavy. So if you plan on wheeling it around your house, or you have an outlet on a further away side of your house, just remember that you may be trudging it through feet of snow, like I do in Maine. So just have a plan in place to have it put somewhere for awhile or the ability to wheel it around with ease. Overall, the generator just looks cool. The black and orange color is cool looking. Obviously not a requirement and individual tastes vary, but it looks like a well built machine and the colors pop. The Generac name is why I went with this one. From past experience of buying cheaper name "knockoffs" to save a few bucks, I have always had it come back to bite me. It's true that you get what you pay for. This unit was priced the same as the knockoffs, too... so why not go for quality, even if you pay just a tad more. But I was very pleased with the price point. LAST, and my ONLY complaint was that I thought the unit came with the L14-30R cord. It DOES NOT. So, if you plan on hooking it up to a 30amp power source, with the 4-prong outlet you will have to purchase the cord separate. Other than that, I am 100% please with the purchase and think you will be too. It powers everything in my house that I need.

Bring on Winter

[This review was collected as part of a promotion.] We live in the country and we have had some hard winters when the electric has been out. We have been wanting a generator for a good while, and finally got one. I didn't know anything about this brand, but "wow"! It had very little assembly out of the box. It is very sturdy and came with large wheels and a handle that uses both hands to keep it balanced, which makes it easy to maneuver. The handle locks in place and folds down when you don't need it. I was really surprised at the features it had. It had 4 plugs, and a 220 volt plug for larger appliances, like a washer or stove. Of course it's not winter, but when the power goes out we will be ready! We hooked it up to our power washer and was able to go beyond what we can usually do around the house. It started with the first pull and had the power to run various items that we tested it with, such as the power washer, welder and we even plugged it into a small camper to run the lights, etc. We are almost wanting a hard winter, just so we can use it. I am very happy with this generator and feel that it will last a lifetime. There is nothing flimsy about it and I think they thought of just about everything with this. I realize we didn't get to try it out for very long, but I can't think of any cons to this generator.

hard to move

I give this 17500E a 5 star rating. The only con I have is the portability. I have to move the gen. around. I mounted a heavy duty caster with brake the second day I owned it , this totally changed the portability, I can move it around with one hand. Also I believe the handle needs to be adjustable so you don't have to do a shoulder lift to get it rolling.

Glad I got this unit

After researching for almost a year, and talking to countless other generator owners, I decided on the Generac line of generators. After extensive comparisons of the Generac portable generators, I decided on the GP7500E since it had the electric start. From the time I ordered until receipt took about five days, and it arrived in great shape, no shipping damage or missing parts. Assembly was a breeze, and in approximateyl 30 minutes, I had the unit assembled and started up. I ran the unit for about an hour, load tested the 30 amp circuit, then packed the unit away in the garage to await the next power outage. One thing to remember about this unit....it's heavy, right at 200lbs, but once it is assembled, the design of the handle makes moving this generator around a breeze.

Quality Generator!

[This review was collected as part of a promotion.] This is a good powerful Generator. It will keep my furnace, refrigerator, and freezer working during a power outage. The instructions to assemble the Generator could have been better. It took a little time to assemble it. Overall a really quality Generator.
