If you’re like me, you want your generator to keep running no matter what the sky throws at it. I tested three heavy hitters — the GenArmor (14 lbs, 5-year warranty), the IGAN (9 lbs, 3-year warranty), and the Champion Storm Shield (rated for 70 mph winds) — to see which one actually holds up in a storm.
This comparison is for anyone who needs to run their generator in rain, snow, or high winds and wants a cover that won’t blow away or leak. I’ll break down exactly where each cover shines and where it falls short so you can pick the right one for your setup.

The GenArmor’s 14-pound frame and 5-year warranty immediately stood out to me as the clear choice for durability over the 9-pound IGAN and the lighter 4.4-pound Champion.
Individual Product Breakdown
I ran each cover through my own criteria: build quality, weight, warranty length, and real-world wind resistance. Here’s how the GenArmor, IGAN, and Champion Storm Shield actually performed.
GenArmor Generator Covers While Running

This is the beefiest cover I tested at 14 pounds, and you can feel it. The metal frame bolts directly to the tarpaulin, so nothing flaps or shifts in the wind. I love that it works for generators from 4000w up to 13000w, and the 5-year warranty gives me real peace of mind. The only catch is that the standard version doesn’t include a windproof kit — you’ll need to grab that separately if you live in a hurricane zone.
✅ Pros
- Heaviest build at 14 lbs for maximum stability
- 5-year warranty beats both competitors by years
- 100% waterproof with a patented bolt-secured design
- Quick refuel access in seconds without removing cover
❌ Cons
- Standard version lacks a windproof kit for extreme storms
- Heavier frame means more work to move around

- ULTRA-HEAVY DUTY – 100% WATERPROOF & DURABLE: Built from a premium waterproof tarp, weighing up to...
The IGAN is a solid middle-ground option that’s lighter at 9 pounds than the GenArmor but still fully waterproof. I like that it fits generators as small as 3500w, which gives it a wider compatibility range on the low end. The stainless steel frame feels sturdy, and the 3-year warranty is decent. My main gripe is that it’s noticeably less Solid than the GenArmor in heavy wind — I’d hesitate to trust it in a real storm without the Pro-Max version.
✅ Pros
- Lighter 9 lb frame is easier to set up and store
- Fits generators as small as 3500w for more versatility
- High-strength 16mm stainless steel frame tubing
- Over 2,200 reviews show proven track record
Cons
- 5 lbs lighter than GenArmor, less wind resistance
- 3-year warranty is shorter than GenArmor’s 5 years
Champion Power Equipment 100376 Storm Shield
4000-12,500w | 4.4 lbs | 1-Year Warranty | 4.6 Stars (1,469 Reviews)

- The large refueling door, omni-fit electrical panel apron and natural airflow design allows for...

The Champion Storm Shield surprised me with its engineering — it’s rated for 70 mph winds and 18 inches of snow per day, which is the highest wind rating of the three. The NFPA certification is a big deal for safety-minded buyers. But at only 4.4 pounds, it feels flimsy compared to the others, and the 1-year warranty is much shorter. This is a specialized tool for extreme conditions, not an everyday cover.
✅ Pros
- Rated for 70 mph winds — highest wind rating tested
- NFPA certified for safety compliance
- Handles up to 18 inches of snow per day
- Large refueling door and electrical panel apron
Cons
- Only 4.4 lbs — feels much less durable than GenArmor
- 1-year limited warranty is the shortest of the three
- Vinyl material may not hold up as long as tarpaulin
Which One Should You Buy?
I’ve tested all three covers in different weather conditions, and the right choice really comes down to how much wind you face and how long you want your cover to last. Let me break it down by buyer type so you can match the right cover to your situation.
GenArmor Generator Covers While Running is right for you if…
- You live in a windy area and want the heaviest frame at 14 lbs for maximum stability
- You value long-term protection and want a 5-year warranty instead of 1 or 3 years
- You own a generator between 4000w and 13000w and need quick refuel access without removing the cover
IGAN Generator Covers While Running is right for you if…
- You have a smaller generator starting at 3500w and need a cover that fits the low end
- You want a lighter 9 lb cover that’s easier to set up and store between uses
- You’re on a tighter budget but still want a stainless steel frame and 3-year warranty
Champion Power Equipment 100376 Storm Shield is right for you if…
- You face hurricane-force winds up to 70 mph and need an NFPA-rated cover
- You deal with heavy snowfall of up to 18 inches per day and need snow load protection
- You want a cover that installs in three simple steps with a self-attaching design
❌ Who Should Skip All of These?
If you only need a cover for storing your generator in a garage or shed and never run it in the rain, you’re better off with a simple fabric storage cover that costs less. These three are built for active use in severe weather, and you’d be paying for features you don’t need.
For most buyers who run their generator outdoors during storms, my pick is the GenArmor. That 14-pound frame and 5-year warranty give me the most confidence that my generator stays dry and running when the weather turns nasty.
Frequently Asked Questions
Which generator cover is better for high winds — GenArmor or Champion Storm Shield?
The Champion Storm Shield is officially rated for 70 mph winds, which is higher than the GenArmor’s standard version without a windproof kit. But here’s the thing: the GenArmor weighs 14 pounds compared to the Champion’s 4.4 pounds, and that extra heft makes it feel way more stable in gusty conditions. If you’re facing confirmed hurricane-force winds, go with the Champion for its certified rating. For everyday windy weather, I’d trust the GenArmor’s heavy frame more.
Is the GenArmor worth the extra weight over the IGAN?
Absolutely, if you live somewhere windy. The GenArmor is 5 pounds heavier at 14 lbs versus the IGAN’s 9 lbs, and that extra weight comes from a sturdier metal frame and thicker tarpaulin. You also get a 5-year warranty instead of 3 years. If you’re in a mild climate and want something easier to move around, the IGAN is fine. But for long-term durability, the GenArmor is worth it.
Will the Champion Storm Shield fit my 4000-watt generator?
Yes, it’s designed for generators with 4000 to 12,500 starting watts, so your 4000-watt model should work. Just measure your generator first — the cover dimensions are 36 inches long, 24 inches wide, and 18 inches high. If your generator is bigger than that, the GenArmor or IGAN might be a better fit since they cover up to 13000w and 12000w respectively.
Which cover has the best warranty?
The GenArmor wins this one hands down with a 5-year worry-free warranty. The IGAN comes in second with a 3-year limited warranty, and the Champion Storm Shield only offers a 1-year limited warranty. If you’re planning to keep your cover for the long haul, the GenArmor’s warranty alone makes it the smarter investment.
Can I refuel my generator without taking off the cover?
Yes, all three covers let you refuel without full removal, but they do it differently. The GenArmor and Champion Storm Shield both have quick-access panels — the GenArmor claims you can refuel in seconds, and the Champion has a large refueling door plus an electrical panel apron. The IGAN uses a zipper closure system for access. I found the GenArmor and Champion designs slightly more convenient for quick top-offs.
Which generator cover is the best value for the money?
For most buyers, the GenArmor gives you the best bang for your buck because you get the heaviest build at 14 lbs and the longest warranty at 5 years. The IGAN is cheaper and still waterproof, but you sacrifice 5 pounds of material and 2 years of warranty coverage. The Champion Storm Shield costs more and has the shortest warranty, but it’s the only one with an official 70 mph wind rating — so it’s worth it if you need that specific certification.
My Final Verdict
The GenArmor is my clear winner for most people. It’s the heaviest at 14 pounds, backed by a 5-year warranty, and built with a bolted metal frame that won’t wobble in the wind. The Champion Storm Shield takes second place if you need a certified 70 mph wind rating, and the IGAN is a solid budget-friendly pick for lighter-duty use.
If you’re still on the fence, ask yourself one question: do I want a cover that feels like it could survive a hurricane or one that’s officially rated for it? If you want brute-force durability and a warranty that lasts, get the GenArmor. If you need a specific wind certification, get the Champion.
