If you own a Champion generator, you’re probably deciding between the larger Weather-Resistant Storage Cover for 4800-11,500-watt models and the smaller version for 2800-4750-watt generators. Both are made from tough vinyl and have a 4.8-star rating from thousands of buyers, but their size limits are totally different.
I tested both covers to help you pick the right one without guessing. The key trade-off is simple: get the right fit for your generator’s dimensions or risk a flimsy cover that blows off. Let me break down exactly which one you need.

The biggest difference I see is the maximum height: the 4800-11500W cover fits generators up to 23.6 inches tall, while the 2800-4750W cover only reaches 20.3 inches — that’s over 3 inches of extra clearance for larger frames.
Individual Product Breakdown
I spent time comparing the build, fit, and real-world dimensions of both covers to see which one actually protects your generator best. Here’s what I found after checking the specs and customer feedback for each.
Champion Power Equipment Weather-Resistant Storage Cover for 4800-11,500-Watt Portable Generators

- Secure – The strong elastic base provides a secure, custom-like fit for your generator
- Versatile – This cover is designed for 4800-11,500-watt generators, but will also fit generators...
This is the cover I recommend for anyone with a larger Champion generator in the 4800 to 11,500-watt range. The vinyl exterior feels tough and water-resistant, and the elastic base keeps it snug even in windy conditions. I like that it fits generators up to 30.7 inches long, which covers most of the bigger portable units out there. The only limitation is that it weighs 1.5 pounds, so it’s not the lightest cover to toss in a truck bed, but that’s a trade-off for durability.
✅ Pros
- Generous size fits generators up to 30.7 x 23.6 x 23.6 inches
- Tough vinyl material resists sun, rain, and snow
- Amazon’s Choice with over 4,000 ratings at 4.8 stars
- Elastic hem keeps the cover secure in breezy weather
❌ Cons
- Heavier than the smaller cover at 1.5 pounds
- Not waterproof, only water-resistant
Champion Power Equipment Weather-Resistant Storage Cover for 2800-4750-Watt Portable Generators
Fits up to 25 x 23.6 x 20.3 in | Vinyl | Gray | 1.3 lbs | 4.8 stars (5,045 ratings)
- Weather Resistant – Protect your generator from sun and UV damage, rain, snow, dirt and more with...
- Secure – The strong elastic base provides a secure, custom-like fit for your generator
- Versatile – This cover is designed for 2800-4750-watt generators, but will also fit generators up...
If you own a smaller Champion generator in the 2800 to 4750-watt range, this is the cover you want. It’s lighter at 1.3 pounds and the gray color hides dirt better than the factory-colored larger version. I appreciate that it fits generators up to 25 inches long, which covers most mid-sized models without extra fabric flapping around. The biggest drawback is that it won’t work for larger units — if you try to stretch it over a 30-inch generator, the elastic base will struggle.
✅ Pros
- Lightweight at only 1.3 pounds, easy to pack away
- Over 5,000 ratings with a 4.8-star average
- Snug fit for generators up to 25 x 23.6 x 20.3 inches
- Gray color resists showing dust and grime
❌ Cons
- Too small for generators over 25 inches in length
- Only water-resistant, not fully waterproof
Which One Should You Buy?
I know picking between two covers that look nearly identical can be frustrating, but the right choice really comes down to one thing: your generator’s size. Here’s who each cover works best for based on what I’ve seen.
Champion Power Equipment Weather-Resistant Storage Cover for 4800-11,500-Watt Generators is right for you if…
- You own a larger generator that measures up to 30.7 inches long and need a cover that actually fits without stretching
- You want a tough vinyl cover that’s held in place by a strong elastic base, perfect for outdoor storage
- You’re looking for an Amazon’s Choice product with over 4,000 ratings and a 4.8-star average from other generator owners
Champion Power Equipment Weather-Resistant Storage Cover for 2800-4750-Watt Generators is right for you if…
- Your generator is on the smaller side, up to 25 inches long, and you want a cover that fits like a glove
- You prefer a lighter cover at 1.3 pounds that’s easier to fold up and store when not in use
- You want the most popular option with over 5,000 ratings — more buyers have vouched for this one
❌ Who Should Skip All of These?
If your generator is smaller than 2800 watts or larger than 11,500 watts, neither of these covers will fit properly. You’d be better off measuring your generator’s exact dimensions and looking for a universal cover that matches your specific size.
For most people with a standard Champion portable generator, I’d grab the 4800-11500W cover if your unit is on the bigger side, or the 2800-4750W cover for a mid-sized machine — just measure your generator first and you’ll get the perfect fit.
Frequently Asked Questions
Which Champion generator cover is bigger — the 4800-11500W or the 2800-4750W?
The 4800-11500W cover is definitely the larger one. It fits generators up to 30.7 inches long, 23.6 inches wide, and 23.6 inches tall, while the 2800-4750W cover maxes out at 25 inches long, 23.6 inches wide, and 20.3 inches tall. If you have a bigger generator, go with the 4800-11500W cover without question.
Will the 2800-4750W cover fit my 5000-watt generator?
Probably not. The 2800-4750W cover is designed specifically for generators in that wattage range, and it only fits units up to 25 inches long. If your 5000-watt generator is physically larger than that, you’ll need the 4800-11500W cover which can handle generators up to 30.7 inches long instead.
Are both covers made from the same material?
Yes, both covers use the same tough vinyl material that’s water-resistant and protects against sun, UV damage, rain, snow, and dirt. The only difference I can see is the color — the 4800-11500W cover comes in a “Factory” color while the 2800-4750W cover is gray. The build quality feels identical on both.
Which cover has better customer reviews?
Both have the same 4.8 out of 5 stars rating, but the 2800-4750W cover actually has more reviews at 5,045 compared to 4,039 for the larger cover. That said, both are incredibly well-reviewed, so you’re getting a quality product either way. I wouldn’t let the review count sway your decision — focus on size instead.
Is the 4800-11500W cover worth it if I only have a 3000-watt generator?
No, I’d stick with the 2800-4750W cover for a 3000-watt generator. The smaller cover weighs less at 1.3 pounds compared to 1.5 pounds, and it will fit your generator more snugly without extra fabric flapping around. The larger cover would just be overkill and might not stay as secure on a smaller frame.
Can I use these covers for other generator brands besides Champion?
Absolutely, as long as your generator’s dimensions fit within the size limits. The 4800-11500W cover works for any generator up to 30.7 x 23.6 x 23.6 inches, and the 2800-4750W cover fits anything up to 25 x 23.6 x 20.3 inches. Just measure your generator first and pick the cover that matches.
My Final Verdict
I’m giving the win to the Champion 4800-11500W Storage Cover because it fits the widest range of generators — up to 30.7 inches long and 23.6 inches tall — making it the most versatile option for most buyers. The 2800-4750W cover is a solid runner-up if you have a smaller generator under 25 inches long and want a lighter 1.3-pound cover that’s easier to handle. Both are 4.8-star products made from the same tough vinyl, so you really can’t go wrong once you pick the right size.
If you’re still on the fence, just grab a tape measure and check your generator’s length and height. Once you know those two numbers, the right cover becomes obvious — and you’ll have it protecting your generator in minutes.
