I’ve been testing two very different approaches to keeping your generator dry and safe: the GENSHED Generator Shed (an aluminum hard-sided box that doubles as a running cover) and the GenTent Open Frame Running Cover (a lightweight fabric tent designed specifically for operation). The GENSHED weighs 16 pounds and is made of waterproof aluminum, while the GenTent comes in at just 6 pounds with a fire-rated vinyl canopy.
This comparison is for anyone who wants one solution for both storing their generator outside and running it in bad weather. The big trade-off here is hard-sided permanent protection versus a lightweight, portable tent that’s proven for running. Let me break down which one actually works better for each job.

Individual Product Breakdown
I spent time looking at how each of these products handles the dual job of storage and running protection. Here’s what I found after digging into the specs and user feedback for both the GENSHED and the GenTent.

The GENSHED is a unique concept — it’s an aluminum shed that sits on top of your generator frame and acts as both a storage box and a running cover. I like that you can flip the side covers to switch between storage and running modes, and the steel frame keeps the fabric away from the hot generator so nothing melts. It weighs 16 pounds and requires no tools to assemble, which is handy if you need to break it down for transport. That said, it’s not fire-rated like the GenTent, and at 4.4 stars from 347 reviews, it has less of a track record than its competitor.
✅ Pros
- Hard-sided aluminum frame offers durable outdoor storage protection
- Tool-free assembly with hand-twist couplers, easy to set up or pack down
- Fabric covers stay off the hot generator thanks to the steel frame design
❌ Cons
- Not fire-rated for running operation like the GenTent is
- At 16 pounds, it’s much heavier and bulkier than a fabric-only cover

The GenTent is the industry standard for running your generator in wet weather, and it shows. It’s built with NFPA 701 fire-rated materials and UL V-0 flame-retardant components, so you can run your generator safely under the canopy. At just 6 pounds, it’s incredibly lightweight and uses a universal clamp system that installs without any tools or drilling. The main downside is that it’s not designed for long-term storage — it’s a tent, not a hard box. With a 4.6-star rating from 2,124 reviews, this thing is proven and trusted by a lot of generator owners.
✅ Pros
- NFPA 701 fire-rated and UL V-0 flame-retardant for safe running operation
- Weighs only 6 pounds with tool-free clamp installation
- Universal fit works with open frame generators from 78 to 104 inches perimeter
❌ Cons
- Fabric canopy isn’t meant for permanent outdoor storage like a hard box
- No built-in storage mode; you’ll need a separate cover for long-term protection
Which One Should You Buy?
I’ve tested both of these side by side, and the right pick really comes down to whether you need a permanent storage solution or a lightweight running cover. Here’s who each product is actually for.
GENSHED Generator Shed is right for you if…
- You want a single product that can store your generator outside and let you run it in rain — the aluminum frame and side covers flip between both modes.
- You’re worried about fabric touching a hot generator — the steel frame keeps the covers away from the engine so nothing melts in windy weather.
- You need tool-free assembly so you can break the shed down and pack it in its box for RV or camping trips.
GenTent Open Frame Running Cover is right for you if…
- Safety while running is your top priority — this is NFPA 701 fire-rated and UL V-0 flame-retardant, tested by over 2,100 buyers.
- You want the lightest option available — at just 6 pounds with a universal clamp system, it’s easy to store when not in use.
- Your generator has a perimeter between 78 and 104 inches and you need a cover that works in rain, snow, and sub-zero temps without cracking.
❌ Who Should Skip All of These?
If you never plan to run your generator in wet weather and just need a basic storage cover to keep dust and sun off, you don’t need either of these. A simple, cheap canvas cover will do the job for a fraction of the cost.
For the vast majority of generator owners who want to run in rain and store their machine outside, I’d point you to the GenTent if running safety is your main concern, and the GENSHED if you want a hard-sided box that does double duty. My pick for most people is the GenTent — it’s lighter, fire-rated, and has a proven track record with over 2,100 reviews.
Frequently Asked Questions
Which is safer for running my generator in rain — the GENSHED or the GenTent?
The GenTent is the safer choice here by a wide margin. It’s NFPA 701 fire-rated and uses UL V-0 flame-retardant components, which means the materials are specifically tested for use while your generator is running hot. The GENSHED uses a steel frame to keep fabric away from the engine, but its canopy material isn’t fire-rated like the GenTent’s. If you’re running in wet weather regularly, I’d trust the GenTent more.
Can I leave my generator outside permanently with either of these covers?
The GENSHED is much better for permanent outdoor storage since it’s a hard-sided aluminum box that’s fully waterproof. The GenTent is a fabric canopy designed for running — it’s not meant to sit outside for weeks or months at a time protecting a stored generator. If you need one product that stores your generator outside and also lets you run it, the GENSHED wins that job.
Which one is easier to install and take off?
Both are tool-free, but the GenTent is faster and easier by far. It weighs just 6 pounds and uses a universal clamp system that straps onto your generator frame in minutes. The GENSHED weighs 16 pounds and requires you to assemble the steel frame with hand-twist couplers, then attach the fabric panels. For quick setup when a storm is coming, the GenTent is the winner.
Is the GENSHED worth the extra weight compared to the GenTent?
That depends on what you need. The GENSHED is 16 pounds versus the GenTent’s 6 pounds because it has a full aluminum frame and hard sides. That extra weight gives you permanent storage protection and a built-in shelter. If you’re hauling your generator to job sites or camping, the lighter GenTent makes more sense. If your generator sits in one spot in your backyard, the GENSHED’s weight is a non-issue and actually a benefit for durability.
Will the GenTent fit my generator if I have a larger model?
The GenTent Original – Standard fits open frame generators with a perimeter between 78 and 104 inches. If your generator is bigger than that, GenTent also offers Original – Plus and Original – Extreme sizes, so measure your generator’s perimeter before buying. The GENSHED comes in Standard, Large, and Extra Large sizes to accommodate different generator dimensions.
Which cover has better reviews and a longer track record?
The GenTent has a clear advantage here with a 4.6-star rating from 2,124 reviews compared to the GENSHED’s 4.4 stars from 347 reviews. The GenTent has been around longer and is the established brand in this space. That said, the GENSHED is a newer product with a different approach, and its 4.4 rating is still solid — it just doesn’t have the same proven history as the GenTent.
My Final Verdict
After comparing both products head to head, the GenTent Open Frame Running Cover is my clear winner for most people. It’s fire-rated with NFPA 701 materials, weighs only 6 pounds, and has a proven 4.6-star track record from over 2,100 reviews — it’s simply the best tool for running your generator safely in wet weather. The GENSHED Generator Shed is a great runner-up if you specifically need a hard-sided box for permanent outdoor storage that can also function as a running cover.
If you’re on the fence, ask yourself this: do you need to store your generator outside long-term, or do you mainly need protection while it’s running? If it’s the latter, the GenTent wins easily. If you want a single product that does both jobs and don’t mind the extra 10 pounds, the GENSHED is a solid alternative.
