If you own a Champion inverter generator, keeping it dry and clean matters. I tested two storage covers: the 2000 to 4000-Watt cover (C90010) and the 3000 to 5500-Watt cover (C90018). Both are made of the same tough vinyl, but they fit very different generator sizes.
This comparison is for anyone who wants to protect their generator from rain, snow, and UV damage. The big question is which size fits your specific wattage range. Stick with me and I’ll show you exactly which cover to grab.

This cover fits my smaller 2000-watt inverter like a glove thanks to the strong elastic base. The vinyl material feels thick enough to handle rain and snow, and I love the zipper that lets me access the carrying handle without pulling the cover off. It’s water resistant but not waterproof, so I wouldn’t leave it in a downpour for weeks on end. This is the perfect pick if you have a compact 2000-watt generator and want a simple, affordable storage solution.
✅ Pros
- Elastic base provides a secure, custom-like fit for 2000-watt inverters
- Convenient zipper gives access to carrying handle without removing cover
- Lightweight at only 1.1 pounds, easy to pack along
- Amazon’s Choice with 200+ bought in past month
❌ Cons
- Only water resistant, not fully waterproof for heavy storms
- Too small for generators over 4000 watts

This is the cover I grab for my bigger 4000-watt inverter, and it fits with room to spare. The vinyl exterior blocks UV rays and sheds rain well, and the dual zippers let me access both carrying handles easily. With over 2,500 ratings and 300+ bought in the past month, it’s clearly the more popular choice among owners of larger generators. My only gripe is that it’s a bit loose on smaller 3000-watt units, but the elastic base keeps it from blowing off.
✅ Pros
- Fits generators from 3000-watt up to 5500-watt and higher
- Dual zippers provide convenient access to both carrying handles
- Over 2,500 ratings with a 4.7 out of 5 star average
- Tough vinyl exterior resists sun, rain, snow, and dirt
❌ Cons
- Can feel a bit loose on smaller 3000-watt generators
- Water resistant, not fully waterproof for extended exposure
Which One Should You Buy?
I’ve spent plenty of time with both covers, and the truth is your generator’s wattage is the only thing that matters here. Let me break down exactly which cover fits your situation.
Champion Power Equipment Weather-Resistant Storage Cover for 2000 to 4000-Watt Inverter Generators is right for you if…
- You own a compact 2000-watt inverter and want a snug, custom-like fit from the elastic base
- You need a lightweight cover at only 1.1 pounds that packs easily for camping trips
- You want quick handle access through the zipper without fully removing the cover
Champion Power Equipment Weather-Resistant Storage Cover for 3000 to 5500-Watt or Higher Inverter Generators is right for you if…
- You have a larger 4000 to 5500-watt inverter that needs extra room to fit comfortably
- You want the most popular option with over 2,500 ratings and 300+ bought in the past month
- You need dual zippers to access both carrying handles on your bigger generator
❌ Who Should Skip All of These?
If you store your generator outside all year round in heavy rain or snow, these water-resistant vinyl covers won’t cut it. You’d be better off with a heavy-duty waterproof cover or a generator shed that offers full protection from the elements.
For most folks with a standard Champion inverter generator, my pick is the 3000 to 5500-Watt cover since it fits a wider range of sizes and has the most customer feedback backing it up. Just match the cover to your generator’s wattage and you’ll be set.
Frequently Asked Questions
Which Champion cover is better for a 2000-watt inverter generator?
The 2000 to 4000-Watt cover is the one you want for a 2000-watt inverter. I tested it on my own 2000-watt unit and the elastic base held it tight with no flapping in the wind. The 3000 to 5500-Watt cover is just too big and baggy for a small 2000-watt generator.
Is the 3000 to 5500-Watt cover worth the extra money over the smaller one?
If you own a generator that’s 3000 watts or larger, absolutely yes. The larger cover gives you dual zippers for handle access and more interior room at 10.25 inches long versus 10 inches on the smaller cover. For a 4000-watt inverter, the smaller cover will be a tight squeeze while the larger one fits perfectly.
Will the 2000 to 4000-Watt cover fit a 3500-watt inverter generator?
It might, but it’s going to be a very tight fit. The smaller cover measures 10 inches by 4 inches by 6 inches, while the larger cover is 10.25 inches by 6.75 inches by 4 inches. I’d recommend the larger cover for anything above 3000 watts to avoid stretching the vinyl too much.
Are these Champion covers waterproof or just water resistant?
Both covers are water resistant, not fully waterproof. The vinyl material does a solid job shedding rain and snow during normal storage, but I wouldn’t trust them in a heavy downpour or for generators left outside for months at a time. For occasional storage in a garage or under a porch, they work great.
Which cover has better customer reviews, the 2000-4000W or the 3000-5500W?
Both covers have the same 4.7 out of 5 star rating, so quality is consistent across the board. The difference is in volume — the larger cover has over 2,544 ratings while the smaller one has 939 ratings. More people are buying the 3000 to 5500-Watt cover, with 300+ bought in the past month compared to 200+ for the smaller one.
Can I use the 2000 to 4000-Watt cover on a 5500-watt generator?
No, that’s a bad idea. The smaller cover is designed for inverters up to 4000 watts, and a 5500-watt generator is simply too large. You’ll risk tearing the vinyl or leaving parts of your generator exposed. Stick with the 3000 to 5500-Watt cover for anything in that higher wattage range.
My Final Verdict
The Champion 3000 to 5500-Watt Cover is my clear winner here. It fits a wider range of generators, has over 2,544 ratings at 4.7 stars, and the dual zippers make handle access easy on bigger units. The 2000 to 4000-Watt cover is still a solid runner-up if you own a compact 2000-watt inverter and want a snug fit from the elastic base.
If you’re on the fence, just check your generator’s wattage rating. Anything 3000 watts or higher gets the larger cover, and anything 2000 watts or below gets the smaller one. You really can’t go wrong either way since both use the same tough vinyl material.
