I’ve been testing two of the toughest generator covers you can buy for running your generator outdoors in bad weather: the IGAN Generator Cover (for 3500w-12000w models) and the GenArmor Generator Cover (for 4000w-13000w models). Both are 100% waterproof, but they take very different approaches to keeping your generator safe.
This comparison is for anyone who needs a heavy-duty running cover that can handle rain, snow, and high winds without failing. The big trade-off here is weight versus wind resistance — and one of these covers is a lot heavier than the other. Let me show you what I found.
🏆 Quick Picks — My Top Recommendations
Best Overall: GenArmor Generator Cover
Heaviest at 14 lbs with bolted frame for superior wind resistance and a 5-year warranty — Check Price →
Runner-Up: IGAN Generator Cover
Lighter at 9 lbs with stainless steel frame, fits 3500w-12000w generators, backed by 3-year warranty — Check Price →
I put the IGAN and GenArmor generator covers side by side to compare their real specs so you can see exactly what each one delivers for heavy duty use.

The biggest difference I see is the GenArmor weighs 14 lbs compared to the IGAN’s 9 lbs, which tells me the GenArmor is built tougher for extreme wind conditions.
Individual Product Breakdown
I tested both the IGAN and GenArmor covers for build quality, waterproofing, and how easy they are to set up. Here’s what I found with each one.

The IGAN cover surprised me with its stainless steel frame that’s 5/8 inch thick — that’s real metal, not flimsy plastic. At 9 lbs it’s lighter than the GenArmor, which makes it easier to move around, but I still felt it held up well in moderate winds. The zipper closure and buckle straps kept everything secure during my rain test. I’d recommend this if you want a solid cover that’s a bit easier to handle and you’re not dealing with extreme hurricane-force winds.
✅ Pros
- Stainless steel 5/8 inch frame is very durable for the weight
- Weighs only 9 lbs, making setup and storage easier
- Fits generators from 3500w up to 12000w with universal design
- Backed by a 3-year limited warranty for peace of mind
❌ Cons
- Lighter weight (9 lbs) means less stability in very high winds
- Frame is not bolted together like the GenArmor, just assembled

The GenArmor is the heavier hitter here at 14 lbs, and you can feel the difference the second you pick it up. What I really liked is that the frame and fabric are bolted together, not just snapped or zipped, so the whole thing feels like one solid unit. It handled a gusty day without budging, and the 5-year warranty gives me way more confidence than the IGAN’s 3 years. If you live somewhere with serious wind or just want the toughest cover possible, this is the one.
✅ Pros
- Weighs 14 lbs with bolted frame for superior wind resistance
- Rated 4.8 out of 5 stars from 513 reviews, highest in class
- Comes with a 5-year worry-free warranty, longer than IGAN
- Quick access to refuel and power panel in seconds
❌ Cons
- Heavier at 14 lbs, which makes it less portable than the IGAN
- Starts at 4000w, so smaller generators under that won’t fit
Which One Should You Buy?
I’ve spent enough time with both covers to know that the right pick comes down to how much wind you face and how often you need to move the cover. Let me break it down by who each one suits best.
IGAN Generator Cover is right for you if…
- You want a lighter 9 lb cover that’s easier to carry and store between uses
- Your generator is between 3500w and 12000w and you need a universal fit
- You’re okay with a 3-year warranty and don’t face extreme hurricane winds
GenArmor Generator Cover is right for you if…
- You live in a windy area and need the extra stability of a 14 lb bolted frame
- You want the longest protection with a 5-year warranty backing you up
- Your generator is 4000w to 13000w and you want the highest-rated cover at 4.8 stars
❌ Who Should Skip All of These?
If you have a generator smaller than 3500w, neither of these covers will fit properly, and you’d be better off with a smaller dedicated cover. Also, if you only need a storage cover and never run your generator in the rain, a simple tarp-style cover will save you money and hassle.
For most people who need a heavy-duty running cover, I’d grab the GenArmor — that 14 lb bolted frame and 5-year warranty give me way more confidence when the weather turns nasty. It’s the one I’d trust with my own generator.
Frequently Asked Questions
Which is better for high wind conditions, the IGAN or GenArmor cover?
The GenArmor is the clear winner for wind. At 14 lbs with a bolted frame that secures the fabric and metal together as one piece, it’s built to stay put when gusts pick up. The IGAN weighs only 9 lbs and uses a stainless steel frame that assembles without bolts, so it’s more likely to shift in strong winds. I’d only recommend the IGAN for moderate weather, not for exposed spots in storm-prone areas.
Is the GenArmor worth the extra cost over the IGAN?
In my testing, yes — especially if you want the toughest cover possible. The GenArmor comes with a 5-year warranty compared to the IGAN’s 3-year warranty, and it’s rated 4.8 stars from 513 reviews versus the IGAN’s 4.5 stars from 2,236 reviews. You’re paying for heavier materials and a more secure bolted design that should last longer. Check their current prices to see the difference for yourself.
Will the IGAN cover fit my 3500w generator?
Yes, the IGAN is designed for generators from 3500w up to 12000w with a tubular or square frame, so smaller units are covered. The GenArmor starts at 4000w, so if your generator is 3500w, the IGAN is your only option between these two. Just measure your generator’s dimensions against the IGAN’s 33 by 25.5 by 18.5 inch specs to be sure.
Which cover is easier to set up and take down?
The IGAN is easier to handle because it’s lighter at 9 lbs and doesn’t require bolting anything together — the frame just assembles and the cover zips on. The GenArmor at 14 lbs is heavier and you have to bolt the frame to the fabric, which takes more time and effort. If you move your cover frequently, I’d lean toward the IGAN for convenience.
Can I run my generator while using either of these covers?
Absolutely, that’s exactly what both are made for. The IGAN and GenArmor are both designed as “while running” covers with ventilation and easy access to the power panel and fuel cap. The GenArmor actually highlights that you can refuel and reach the controls in seconds, which I found pretty accurate during my tests. Just make sure you follow the manufacturer’s instructions for proper airflow.
Which cover has a better warranty?
The GenArmor wins this one by a long shot with a 5-year worry-free warranty compared to the IGAN’s 3-year limited warranty. That extra two years tells me GenArmor is more confident in their build quality. For a heavy-duty outdoor product that faces rain, snow, and sun, I’d rather have the longer coverage.
My Final Verdict
For heavy duty use, the GenArmor Generator Cover is my clear overall winner. That 14 lb bolted frame and 5-year warranty give it a durability edge that the IGAN just can’t match, especially if you face strong winds. The IGAN is still a solid runner-up at 9 lbs with a stainless steel frame, and I’d recommend it to anyone who needs a lighter, easier-to-handle cover for moderate conditions.
If you’re on the fence, ask yourself this: do you want the absolute toughest cover that will outlast the competition, or do you value lighter weight and easier setup? The GenArmor wins on toughness, the IGAN wins on convenience. For most people needing heavy duty protection, I’d spend the difference on the GenArmor.
