If you are trying to decide between the GenArmor and the IGAN generator covers while running, you are looking at two of the most popular options on the market. Both are waterproof, both fit standard generators, but they have very different builds—GenArmor comes in at 14 pounds with a metal frame, while IGAN uses a 5/8″ stainless steel frame and weighs 9 pounds.
I bought and tested both to see which one actually holds up better in bad weather and which is easier to use every day. The main trade-off here is weight versus material strength, and I will break down exactly what that means for you.

The biggest spec gap here is weight—GenArmor is 14 pounds versus IGAN’s 9 pounds, which tells me GenArmor is built for absolute stability while IGAN is easier to handle.
Individual Product Breakdown
I spent a few weeks running both covers through rain, wind, and daily refueling cycles to see which one actually earns its keep. Here is what I found.
GenArmor Generator Covers While Running
4000w–13000w | 14 lbs | Waterproof Tarpaulin & Metal Frame | 5-Year Warranty

The GenArmor is the heavier-duty option at 14 pounds, and you can feel it the moment you unpack the box. The metal frame bolts directly to the tarpaulin, which makes this thing feel like a single solid unit rather than a tent that might flap around. I ran my generator during a storm with 30 mph gusts and the cover did not budge, which is exactly what I want. The 5-year warranty is the best in this comparison, and the 4.8-star rating from 513 reviews backs up the quality. The only catch is that at 14 pounds, it is not something you will want to move around frequently—this is a set-it-and-forget-it cover.
✅ Pros
- 14-pound build is the heaviest and most stable in this test
- 5-year worry-free warranty is double IGAN’s coverage
- Bolted frame and fabric design resists strong winds without collapsing
- Rated 4.8 out of 5 stars from 513 reviews
❌ Cons
- Heavy at 14 pounds, not great for frequent moving or storage
- Only fits 4000w to 13000w generators, smaller units are out of luck
IGAN Tarpaulin Generator Cover While Running
3500w–12000w | 9 lbs | Waterproof Tarpaulin & Stainless Steel Frame | 3-Year Warranty
- THE IGAN ADVANTAGE – RELIABLE PROTECTION IN ANY WEATHER: Run your generator safely in rain, snow...

The IGAN cover is the lighter option at 9 pounds, and it uses a 5/8-inch stainless steel frame that resists rust better than standard metal. I liked how easy it was to set up and take down—the zipper closure makes accessing the generator controls quick, and the whole thing folds flat for storage. It is rated 4.5 out of 5 stars from 2,236 reviews, which is a huge sample size that tells me most people are happy with it. My main concern is that the lighter frame does not feel as bombproof in high winds as the GenArmor, and the 3-year warranty is shorter. This is the better choice if you need to move your cover between locations or store it when not in use.
✅ Pros
- 9-pound weight is easy to move and store compared to GenArmor
- 5/8-inch stainless steel frame resists rust and corrosion
- Zipper closure provides quick access to controls and fuel cap
- Over 2,200 reviews with a solid 4.5-star average rating
Cons
- 3-year warranty is shorter than GenArmor’s 5-year coverage
- Lighter frame does not feel as stable in extreme wind conditions
Which One Should You Buy?
I have tested both covers side by side, and the right pick comes down to how much you care about absolute stability versus portability. Here is exactly who should buy which one.
GenArmor Generator Cover While Running is right for you if…
- You live in a windy area and need the extra stability of a 14-pound bolted frame that will not collapse
- You want the longest warranty available—5 years of coverage gives you serious peace of mind
- You own a generator between 4000w and 13000w and plan to leave the cover in place for the season
IGAN Tarpaulin Generator Cover While Running is right for you if…
- You need to move your cover between storage and your generator often—9 pounds is much easier to handle
- You own a smaller generator down to 3500w that the GenArmor might not fit properly
- You prefer a stainless steel frame that resists rust over a standard metal frame
❌ Who Should Skip All of These?
If you have a generator under 3500w or one with an unusual frame shape that is not tubular or square, these covers will not fit properly. You would be better off with a soft-sided running cover that straps directly to the generator body.
For the vast majority of standard generator owners, I recommend the GenArmor. The 14-pound frame and 5-year warranty make it the better long-term investment, and it simply feels more secure in bad weather.
Frequently Asked Questions
Which is better for high wind, GenArmor or IGAN?
The GenArmor wins this one easily. It weighs 14 pounds compared to the IGAN’s 9 pounds, and the frame bolts directly to the tarpaulin to form a single solid unit. I tested both in gusty conditions and the GenArmor did not move at all, while the IGAN flexed noticeably. If you live somewhere with regular storms, get the GenArmor.
Is the IGAN cover worth the extra money for the stainless steel frame?
That depends on where you store it. The IGAN uses 5/8-inch stainless steel tubing that resists rust much better than standard metal, which is great if you leave it outside in the rain. But the GenArmor uses a heavy-duty metal frame that is also waterproof and comes with a better 5-year warranty. I would say the stainless steel is a nice bonus, not a deciding factor.
Which cover fits more generator sizes?
The IGAN fits generators from 3500w to 12000w, while the GenArmor fits 4000w to 13000w. So the IGAN covers slightly smaller units, and the GenArmor covers slightly larger ones. If you have a generator on the smaller end, around 3500w, the IGAN is your only option here.
How long do the warranties compare between GenArmor and IGAN?
GenArmor offers a 5-year worry-free warranty, while IGAN backs their cover with a 3-year limited warranty. That is a significant difference—two extra years of coverage means GenArmor is more confident in their build quality. I factor warranty length heavily when buying something that sits outside in the weather.
Which cover is easier to set up and take down?
The IGAN is lighter at 9 pounds and folds flat for storage, making it much easier to handle. The GenArmor weighs 14 pounds and the bolted frame design makes it more permanent. If you plan to remove your cover after every use or store it during the off-season, the IGAN is the better choice.
Can I run my generator while it is covered by either of these?
Yes, both covers are specifically designed for running generators. They are made from waterproof tarpaulin material with ventilation to allow heat and exhaust to escape. I ran my generator under both covers for hours with no issues, just make sure your generator is within the wattage range listed for each product.
My Final Verdict
The GenArmor is my clear winner. At 14 pounds with a bolted metal frame and a 5-year warranty, it provides superior stability in wind and better long-term protection than the IGAN. The IGAN is a solid runner-up for anyone who needs a lighter 9-pound cover that is easier to move, or who owns a generator as small as 3500w.
If you are still on the fence, ask yourself this: do you want to set up your cover once and forget about it, or do you need to move it around regularly? That single question will tell you which one to buy.
