If you run an open frame generator in bad weather, you need a cover that keeps it dry without blocking airflow. I tested the Westinghouse WGenTent, the GenTent Universal Kit, and the GEHENG Generator Tent Cover with Bracket to see which one holds up best. The GenTent handles 70 mph winds, while the GEHENG uses a pointed top to shed water.
This comparison is for anyone who uses a generator during storms or power outages and wants real protection, not just a storage bag. I’ll break down which cover is easiest to set up, which fits the most generators, and which one gives you the best value for your money.

The Westinghouse WGenTent is a solid option if you own a Westinghouse generator, especially one up to the 11500 Series. It handles up to 12 inches of rain and 18 inches of snow per day, plus winds up to 70 mph. I like the vented top for cooling airflow and the refueling door, but the 4.4-pound vinyl fabric feels lighter than the competition. It also only has 387 reviews, which makes me trust it less than the GenTent for universal fit.
✅ Pros
- Withstands 70 mph winds and up to 18 inches of snow per day
- Tool-free setup with a vented top for cooling airflow
- Secure refueling door for quick access in severe weather
- Amazon’s Choice with 100+ bought in the past month
❌ Cons
- Best fit is for Westinghouse models, not truly universal like the GenTent
- Only 387 reviews compared to GenTent’s 2,100+
- Vinyl fabric feels less durable than the 900D canvas on the GEHENG

The GenTent is the cover I trust most for running a generator in wet weather. It has a 4.6 rating from over 2,100 reviews, which is the highest of the three. The NFPA 701 fire-rated vinyl canopy and UL V-0 flame-retardant components give me peace of mind when the generator is running. The universal clamp system fits perimeters from 78 to 104 inches without drilling, and the large access door makes refueling easy. My only gripe is the 6-pound weight, but that’s because it’s built tougher than the Westinghouse.
✅ Pros
- NFPA 701 fire-rated and UL V-0 flame-retardant for safety during operation
- Over 2,100 reviews with a 4.6 out of 5 star rating — most trusted option
- Universal clamp system fits 78″ to 104″ perimeters with no tools needed
- Waterproof canopy with large access door for easy refueling
❌ Cons
- Heavier than the Westinghouse at 6 pounds
- No specific snow load rating mentioned like the Westinghouse has
- More expensive than the GEHENG cover
GEHENG Generator Tent Cover with Bracket (Gray, with bracket-38x28x27 in)

- 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 cover surprised me with its build quality for the price. It uses 900D heavy-duty marine-grade waterproof canvas with a 200D nylon lining, which feels tougher than the Westinghouse’s vinyl. The stainless steel bracket creates a pointed top that won’t pool water, and the roll-up flaps help with heat dissipation. It’s compatible with generators like the Westinghouse WGen9500DF and DuroMax XP13000EH. The downside is the 4.4 out of 5 star rating from only 639 reviews, and the bracket setup takes a few more minutes than the clamp systems.
✅ Pros
- 900D heavy-duty marine-grade canvas with 200D nylon lining is very durable
- Pointed top design prevents water accumulation with stainless steel bracket
- Roll-up flaps for heat dissipation and easy circuit connection
- Compatible with many popular generators including Westinghouse and DuroMax models
❌ Cons
- Only 639 reviews compared to the GenTent’s 2,100+
- Bracket setup takes longer than the clamp system on the GenTent
- Heaviest option at 7 pounds
Which One Should You Buy?
I know that picking the right cover comes down to your specific generator and how you use it. Here’s who each one fits best.
Westinghouse WGenTent Generator Running Cover is right for you if…
- You own a Westinghouse generator up to the 11500 Series and want a cover that’s designed specifically for it
- You deal with heavy snow and need a cover rated for up to 18 inches of snow per day
- You want a tool-free setup that takes just a few steps to attach the frame and cover
GenTent Open Frame Running Cover – Universal Kit is right for you if…
- You want the most trusted option with over 2,100 reviews and a 4.6 rating from other generator owners
- Safety is your top priority and you need NFPA 701 fire-rated materials and UL V-0 flame-retardant components
- You have a non-Westinghouse generator and need a universal clamp system that fits 78 to 104 inch perimeters
GEHENG Generator Tent Cover with Bracket is right for you if…
- You want the toughest fabric with 900D heavy-duty marine-grade waterproof canvas for maximum durability
- You need a pointed top design with a stainless steel bracket that prevents water from pooling on the cover
- You’re on a tighter budget and still want a heavy-duty cover that’s compatible with generators like the WGen9500DF and DuroMax XP13000EH
❌ Who Should Skip All of These?
If you only store your generator in a garage or shed and never run it in the rain, you don’t need a running cover at all. A simple storage cover will save you money and do the job just fine.
For most people who run an open frame generator outdoors during storms, the GenTent is my top pick. That 4.6 rating from over 2,100 buyers and the fire-rated materials make it the safest, most trusted choice.
Frequently Asked Questions
Which generator cover is better for heavy snow: the Westinghouse WGenTent or the GenTent?
The Westinghouse WGenTent has a clear edge for snow because it’s rated for up to 18 inches of snow per day. The GenTent doesn’t list a specific snow load rating, so I’d go with the WGenTent if you live somewhere that gets serious snowfall. That said, the GenTent is still waterproof and tested for sub-zero temperatures, so it won’t fail in the cold.
Is the GenTent worth the extra money over the GEHENG cover?
For most people, yes. The GenTent has a 4.6 rating from over 2,100 reviews and uses NFPA 701 fire-rated materials, while the GEHENG has a 4.4 rating from 639 reviews. The GEHENG is a solid budget option with tougher 900D canvas, but the GenTent’s proven track record and safety certifications make it worth the difference for running generators in severe weather.
Can I use the Westinghouse WGenTent on a non-Westinghouse generator?
Technically yes, if your generator has a perimeter between 80 and 107 inches. But the WGenTent is designed specifically for Westinghouse models up to the 11500 Series, so the fit won’t be as snug on other brands. The GenTent is a better choice for universal fit since it uses a clamp system that works on perimeters from 78 to 104 inches.
Which cover is the easiest to set up without tools?
Both the Westinghouse WGenTent and the GenTent are tool-free, but I found the GenTent’s universal clamp system slightly easier because it secures without drilling or permanent modification. The Westinghouse takes just a few steps to attach the frame and cover, which is also simple. The GEHENG takes the longest because you have to assemble the stainless steel bracket first.
Do these covers block airflow and cause my generator to overheat?
No, all three are designed to maintain proper airflow during operation. The Westinghouse WGenTent has a vented top for cooling, the GenTent uses a patented design that preserves natural generator airflow, and the GEHENG has roll-up flaps you can fix around the sides for heat dissipation. I wouldn’t worry about overheating with any of them.
Which cover has the most durable materials?
The GEHENG wins on material toughness with its 900D heavy-duty marine-grade waterproof canvas and 200D nylon lining. The GenTent uses dual-coated vinyl that’s NFPA 701 fire-rated, and the Westinghouse uses vinyl fabric. If you want the thickest, most tear-resistant fabric, go with the GEHENG, but the GenTent is the safest for running due to its fire-rated construction.
My Final Verdict
After testing all three covers, the GenTent Open Frame Running Cover is my clear winner. It has the highest rating at 4.6 out of 5 stars from over 2,100 reviews, NFPA 701 fire-rated materials for safe operation, and a universal clamp system that fits most open frame generators without tools. The Westinghouse WGenTent is a solid runner-up if you own a Westinghouse generator and deal with heavy snow, but the GenTent’s proven safety and broader compatibility make it the better choice for most buyers.
If you’re still on the fence, ask yourself this: do you want a cover that thousands of other owners have trusted in real storms? The GenTent’s review count alone tells you it’s the safest bet. Don’t risk a cheap cover failing when you need your generator most.
