   This generator cover feels really solid and well made. I love that it’s heavy-duty and has a silver-coated interior, which makes it feel like it will offer excellent protection. It’s very complete — it even has pockets and a special flap with a zipper on top, so you can connect the generator without having to remove the whole cover. It fit my generator perfectly, and it also comes with a small bag you can use to store the cover itself or other generator accessories. Very happy with it!

   heavy duty cover. I got this because you can run your generator with the cover on for bad weather. No instructions included. There is a bag for the cover, the cover, and a top for the cover included.

   At first, getting the cover situated on the smaller generator took a moment to figure out, but once in place, it worked seamlessly. The plastic window made it easy to access the outlets and check the gauges, even in rainy conditions. The reflective material not only helps keep the generator cooler but also makes it highly visible at night—especially useful when pulling into the driveway. The cover is designed with multiple attachment points, making it adaptable for different generator sizes. I’ve used it on both a 10k-watt and a 5k-watt model, and the fit was effortless. It simply slipped over the top, and the adjustable straps secured it firmly in place. Beyond functionality, it looks great sitting in the driveway, providing much-needed protection against debris and rain. Made from a strong, fire-retardant material, this cover is a solid choice for anyone looking to safeguard their generator with durability and convenience. Just need to make sure to size accordingly.

   Most generator covers that can be used while the generator is running cost more in the upper hundreds. For only $47, this cover is cheap, oversized, and a little difficult to set up, but it does work well. The quality is decent, and it helps protect the generator from the elements—whether it’s out in the weather or stored in the garage. The fuel fill-up cover is a nice touch. I’m using this on a Generac GP6500, and this cover does its job. It’s nice to have so that the generator doesn’t get soaked during a big storm. Pros: Protects well from the elements. I love that it can be used while the generator is running. It folds up nicely. Cons: It came with a storage bag, but once taken out, it’s impossible to put back in. It’s oversized for my generator, as this is a universal fit. The top Velcro cover is a tad funky.

   Great fit, durable fabric, dust and water protection. It works well, but I have doubts about how long the clear panels will last. The price was good compared to other options, and the zippers on each corner make it easy to install and remove, but they do not stay closed when the wind blows the cover up.

   This durable generator cover fits our Generac Powermate PM 9400E just fine. Confirmed that it is waterproof because after a storm the water was beaded up on the outside and wiped off easily. The clear window is thick. I didn’t see any instructions inlcuded so it took a little longer to figure out how to install it. Great Quality Without the Hefty Price Tag.

   Finally—a generator cover that actually works! My old covers always soaked through or shredded in the wind, but this beast laughs at rain, snow, and even my kids’ chaotic backyard antics. The fabric feels like it could stop a bullet, and the silver-plated lining keeps moisture and heat out (no more melted, sticky mess in summer). Best part? I can run my generator while it’s covered the roll-up sides and mesh window give perfect airflow while keeping debris off. No more frantic tarp wrestling during storms! After a year of abuse, it’s still 100% waterproof, and the heavy-duty zippers haven’t rusted or jammed. Worth every cent for peace of mind. If your generator sleeps outside, this is its forever jacket.
