We just purchased the Champion 4000-Watt Wireless Start Open Frame Inverter and wanted to protect it the best we can so it would last which is why we decided to purchase this cover. In my experience, covers for outdoor items can tend to not fit very well and are made out of pretty cheap material. So you can imagine my being more than pleasantly surprised with I opened the box containing the cover for our new generator. I was at odds before I opened it because we the name of this product says it will cover 2800-Watts or higher but when the product was delivered it has 3100 in big numbers on the carton.After we assembled the new generator, the moment of truth was upon us so I took the cover out of it’s protective plastic bag it ships in and tried to cover the new generator with it. Because the bottom of the cover is elasticized and was new, it took a few minutes to get the cover over the generator. Once I was successful getting it on, I noticed it also has a cord with a stop on the elasticized bottom that allow it to tighten the cover if needed. Not sure I’ll need to pull it tighter because it was more than being a good fit.The description says it is a “weather resistant vinyl” which is true but what I was impressed with is the fact that it is a thicker vinyl and DOES NOT feel cheap at all. In fact, when looking at all of the seams I would say these covers are made very well. What I didn’t notice until AFTER I put it on the generator were the 2 zippers on either end of the cover. What that will allow me to do is be able to lift it via the two handles without taking the cover off. The uploaded picture I took of the new cover is not a “professional” marketing one…it still shows the wrinkles from being boxed.My bottom line is I am glad I took the chance and ordered this cover for our new generator. I really think it will protect the unit when it’s outside from the rain and sun (Florida sun is very destructive to things like barbecues, furniture, and so on).
