Good product

Bought this as a replacement for a Coleman 5500 Vertex that quit producing power. Assembly was straight forward for the wheel kit and handle. Started right up and is noticeably quieter than my old unit. I like the pull cord backup if the battery is dead. Its also nice that is has a fuel gauge. My complaints are the non-charging engine so the battery is only charged from the included 120 volt charger. The other complaint is the electric start switch is on the front panel of the unit and the choke which you have to set before starting and then adjust/turn off upon starting is on the end of the unit. Either move the switch near the choke or add a choke adjustment cable pull on the front panel.

Great unit!

We have had the 17500 for a few years now and it has been great for us. We live near a national forest so when power goes out it generally stays out for several hours to several days. We do the regular maintenance on her and have a trickle charge solar panel on the battery. It definitely burns through fuel, however, it runs EVERYTHING. Also is very heavy, so have so.e strong people around if you need to move it or place it strategically and then buy a sturdy after market cover to keep it out of the elements.

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.

Quality product

Our power has been out for the last 3 days from hurricane dorian, this generator has worked great. We switched our house over to the Generac 8000W generator as soon as we lost power. Fired up AC, some lights, a few receptacles and refrigerator, WORKS GREAT and has worked for us on a tank of gas for 17hrs. HOT HUMID days with no power, glad we have our Generac generator.

Fired up first pull!

Had to put the wheels on but after topping off with oil and gas this thing fired up first pull. It is somewhat quieter than the Stanley that it replaced. Excellent generator for the money. Output seems to be on the upper end of rating. We run power tools and air compressor of it at jobs site. Works great.

Excellent unit but very loud and easy to operate.

The unit was delivered and it took me a few weeks before I set it up. Too bad it doesn't ship with wheel kit already installed, it is a 2 man job for set up. After getting the transfer switch installed, tested the unit on a full load and works great. Easy to crank but had to purchase a charger for the battery after 3 months. It is loud even when placed in idle mode and the metal cover rattles near the muffler. I love it though.

Great Generator, But

I bought this unit for backup power 9 months ago. I run it 30 minutes every month. The last time I started it, it leaked a gallon of gas around the generator. Had I not checked after 5 minutes running, I am sure my building and surrounding buildings would have gone up in a huge fire. Needless to say, I returned the unit for a refund. I can't recommend this without knowing what the problem with the generator is! Never, never, another gasoline generator.

Performance is good

I have the 7000E and from what I can see other than the covered outlets and uni handle bar, it is the same model? The only issue I have so far with the generator is that the on/off fuel valve tab broke on me when I was turning it on. Now I use a tiny vice grip to turn the valve. Hard to find what part number I need for the generator b/c I can't find a parts list but all and all a solid generator.

It exceeds my expectations

I have given this generator a 5 star rating based on my experience with it so far, and so far I haven't needed to use it for the reason it was purchased; to supply emergency power during electrical outages. That having been said, I am impressed with what I have seen so far. The unit arrived in perfect condition, and assembly was easy. I was concerned by the advertised weight at first, but the carton was easily handled by two people, and after assembly, it is easy to move from storage to the driveway where it will be used. The battery was charged when it arrived, and it started right up and ran steadily for about 15 minutes. I had minor difficulty adding the engine oil, in that I had to hunt around for a long necked funnel to use to pour the oil into the unit, no big deal. And, the instructions indicate that you should check the oil level as oil is being added, so as not to overfill the unit. I did this, only to read later that the recommended oil capacity is 1 quart, and exactly one quart of oil was supplied. It would have saved me a few minutes if the instructions said "Pour the 1 quart of enclosed oil into the oil fill plug". Also, no big deal. Finally, it would be nice to have a compartment or something on the unit to hold the battery charger. I solved that problem with a bag attached to the frame with zip ties. If this is all I can find to complain about, I would say that I'm pretty satisfied. I trust that this unit will perform as well when the need arises as it has so far.
