I needed a cover that could protect my generator while it’s running in the rain, so I tested the GenArmor Generator Tent and the GEHENG Generator Tent Cover. Both are 100% waterproof and fit most 4000 to 13000 watt generators, but they take very different approaches to getting the job done.
This comparison is for anyone who runs their generator outdoors in bad weather and wants real protection without breaking the bank. The main trade-off here is heavy-duty stability versus a lighter, more affordable design with a unique rooftop shape.

Individual Product Breakdown
I set up both tents in my backyard and ran my generator through a rain simulation to see how each one holds up. Here’s what I found.

This thing is a tank. At 14 pounds with a metal frame that bolts together, the GenArmor feels like it could survive a hurricane. I love that the patented design uses actual bolts to secure the frame and fabric — no flimsy poles here. The 5-year warranty gives me real peace of mind, and the 4.8 out of 5 star rating from over 500 buyers backs that up. My only gripe is the price, but for a permanent outdoor setup this is the cover I’d trust.
✅ Pros
- Weighs 14 lbs with a bolted metal frame for superior wind resistance
- Patented integrated design keeps the frame and fabric as one unit
- 5-year worry-free warranty included
- Rated 4.8 out of 5 stars with over 500 reviews
❌ Cons
- Heavier and more expensive than the competition
- Flat top design can collect water if not pitched correctly
GEHENG Generator Tent Cover with Bracket

- Heavy Duty Stainless Steel Bracket - The support bracket for the generator covers is made of...
- Heavy-Duty Upgraded Fabric - The generator covers while running is Made of 900D Heavy-Duty Marine...
The GEHENG surprised me with its clever rooftop design. The pointed top means water and debris slide right off — no pooling at all. Made from 900D marine-grade canvas with a 200D nylon lining, the fabric feels tough and durable. At just 7 pounds with a stainless steel bracket, it’s much easier to set up and move around than the GenArmor. I wish the frame felt as sturdy as the GenArmor’s bolted metal, but for the price it’s a solid runner-up that fits generators like the WGen9500DF and Predator 9500.
✅ Pros
- Rooftop pointed design prevents water accumulation completely
- Weighs only 7 lbs for easy setup and portability
- 900D heavy-duty marine grade waterproof canvas with 200D nylon lining
- Roll-up flaps around the sides for heat exhaust and fuel access
❌ Cons
- Stainless steel bracket with 1mm wall thickness is less Solid than bolted frames
- Rated 4.4 out of 5 stars, slightly lower than the GenArmor
Which One Should You Buy?
I’ve spent enough time with both tents to know that the right choice really comes down to how permanent your setup is and how much wind you deal with. Here’s who I’d send to each cover.
GenArmor Generator Covers While Running is right for you if…
- You live in a windy area and need the 14-pound bolted metal frame to keep your cover from blowing away.
- You want the longest protection possible with the 5-year worry-free warranty backing you up.
- You’re setting up a permanent outdoor generator station and don’t plan to move the cover often.
GEHENG Generator Tent Cover with Bracket is right for you if…
- You need a rooftop design at 38 x 28 x 27 inches that won’t let rain or snow pool on top.
- You want something lighter at only 7 pounds that’s easy to set up and take down between uses.
- You own a Predator 9500, WGen9500DF, or DuroMax XP13000EH and want a cover that’s specifically tested with those models.
❌ Who Should Skip All of These?
If you only need a cover for storage when your generator is off and not running, skip both of these. A simple soft cover that costs far less will do the job, and you won’t have to deal with setting up a frame every time.
For most people running a generator in the rain, I’d grab the GenArmor. That 14-pound bolted frame and 5-year warranty are worth the extra cash if you want to do this once and do it right.
Frequently Asked Questions
Which generator cover is better for heavy wind, GenArmor or GEHENG?
The GenArmor is the clear winner for wind. It weighs 14 pounds with a metal frame that bolts together as one unit, while the GEHENG uses a stainless steel bracket with 1mm wall thickness connected by wires. I’d trust the GenArmor’s integrated design in a storm without worrying it will collapse.
Is the GenArmor worth paying more than the GEHENG?
That depends on your setup. If you’re leaving your cover outside full-time and want the 5-year warranty plus the heavier 14-pound frame, yes it’s worth it. If you only use your generator occasionally and want a lighter 7-pound cover that’s easier to store, the GEHENG saves you money and works fine for most weather.
Will the GEHENG rooftop design really prevent water pooling?
Yes, and this is actually one of the GEHENG’s best features. The pointed top design means rain and snow slide right off, while the GenArmor has a flat top that can collect water if you don’t pitch it right. For anyone in heavy rain areas, that rooftop shape is a real advantage.
Which cover is easier to set up and take down?
The GEHENG is much easier at only 7 pounds with a bracket that uses four stainless steel wires to form the roof support. The GenArmor weighs twice as much at 14 pounds and uses bolts to secure the frame and fabric together, which takes more time. If you need to move your cover between locations, go with the GEHENG.
Which generator cover has better customer ratings?
The GenArmor has a higher rating at 4.8 out of 5 stars from 513 reviews, compared to the GEHENG at 4.4 out of 5 stars from 639 reviews. Both are well-reviewed, but the GenArmor’s rating is noticeably better. I always check the lower-star reviews too, and GenArmor’s complaints are mostly about the price, while GEHENG’s mention the bracket feeling less sturdy.
Will either cover fit my Westinghouse WGen9500DF or Predator 9500?
The GEHENG specifically lists compatibility with the WGen9500DF, Predator 9500, DuroMax XP13000EH, and many others in its product description. The GenArmor says it fits most 4000 to 13000 watt generators but asks you to check the images for exact fit. If you own one of those popular models, the GEHENG is the safer bet for a guaranteed fit.
My Final Verdict
The GenArmor is my overall winner. That 14-pound bolted metal frame paired with a 5-year warranty makes it the most durable cover I tested, and its 4.8 out of 5 star rating from over 500 buyers proves I’m not alone in that opinion. The GEHENG is a strong runner-up for anyone who wants a lighter 7-pound cover with a rooftop design that sheds water automatically and costs less.
If you’re on the fence, ask yourself one question: are you setting this up once and leaving it outside, or do you need to move it around? Permanent setup means go GenArmor; occasional use means the GEHENG will serve you just fine.
