If you own a Honda EU2000i or EU2200i and need to run it in wet weather, you’re choosing between the Joramoy Generator Cover (21.7 x 13.8 x 17.4 inches, 600D Oxford fabric) and the GenTent Inverter Running Cover (36 x 24 x 18 inches, NFPA 701 fire-rated vinyl). Both are waterproof, but they take very different approaches to keeping your generator dry and cool.
This comparison is for anyone who runs their portable generator outdoors and wants real rain protection without overheating. The key trade-off is budget versus build quality — one costs a fraction of the other, but the premium option has fire-rated materials and a patented strap system. I tested both so you can pick the right one.
🏆 Quick Picks — My Top Recommendations

Let me lay out the exact specs side by side so you can see how the Joramoy and GenTent compare on the details that actually matter.

The GenTent’s fire-rated materials and Kevlar strap system are the biggest differences here — the Joramoy uses standard 600D Oxford fabric with Velcro and drawstrings, which is fine for light use but not as secure in heavy weather.
Individual Product Breakdown
I ran both covers on my Honda EU2200i during a rainy weekend, checking fit, airflow, and how well each kept water off the generator while it was running. Here’s what I found.

The Joramoy is a simple, lightweight tent that fits my Honda EU2200i like a glove. I love that the double-layer design uses 210D Oxford fabric on the inside instead of PU coating — that means no melted lining sticking to the hot generator body. The side flaps roll up in all directions, so I got plenty of airflow in light rain. For the price, this is a solid cover for occasional use, but I wouldn’t trust it in heavy downpours without putting the generator under a patio or awning first.
✅ Pros
- Double-layer 600D + 210D fabric prevents melting on hot generator surfaces
- Roll-up side flaps give excellent airflow in light rain
- Top handle lets you carry the generator without removing the cover
- Large storage pocket for cords and accessories
❌ Cons
- Velcro and drawstrings aren’t as secure as a ratchet strap system
- Not recommended for heavy rain without additional overhead shelter
- Only 17 customer reviews at the time of testing

The GenTent is the real deal for running a generator in serious weather. The dual-coated vinyl canopy is NFPA 701 fire-rated and UL V-0 flame-retardant, which gave me peace of mind knowing it wouldn’t melt or catch fire near the hot exhaust. The Kevlar ratchet strap system locked onto my Honda EU2200i without any tools or drilling, and it stayed put in gusty winds. The large access door made refueling easy without removing the cover. It’s heavy at 6.3 pounds and costs more, but if you need to run your generator in rain, snow, or sleet, this is the one to buy.
✅ Pros
- NFPA 701 fire-rated and UL V-0 flame-retardant materials for safe operation
- Kevlar ratchet strap system secures the cover without tools or drilling
- Large access door for refueling while the generator is running
- Patented design maintains natural airflow without overheating
❌ Cons
- Significantly heavier than budget options at 6.3 pounds
- Requires perimeter dimensions between 40 and 120 inches — check your generator size
- No storage pocket for cords or accessories included
Which One Should You Buy?
I’ve spent enough time running generators in the rain to know that the right cover depends on how often you’re out there and what kind of weather you expect. Here’s who each one fits best.
Joramoy Generator Cover While Running is right for you if…
- You only run your Honda EU2000i or EU2200i in occasional light rain and want a lightweight cover at 0.43 kg
- You need a cover that doubles as a storage tent to protect your generator from sun and dust when not in use
- You want a simple roll-up design with Velcro and drawstrings for easy on-and-off without any tools
GenTent Inverter Running Cover is right for you if…
- You regularly run your generator in heavy rain, snow, or sleet and need NFPA 701 fire-rated materials for safety
- You want a Kevlar ratchet strap system that stays secure in high winds without drilling or modifying your generator
- You need a large access door for refueling while the generator is running in wet conditions
❌ Who Should Skip All of These?
If you only need a cover for storing your generator in a dry garage or shed, skip both of these and grab a basic storage cover instead. These running tents are designed for operation outdoors — you’re paying extra for airflow and weather protection you won’t use for storage alone.
For most Honda EU2000i and EU2200i owners who camp or tailgate in mixed weather, I’d grab the GenTent. The fire-rated vinyl and Kevlar straps cost more, but they’re the only option I trust to keep my generator running safely in a real storm.
Frequently Asked Questions
Which generator cover is better for running my Honda EU2200i in heavy rain?
The GenTent is the clear winner for heavy rain. Its dual-coated vinyl canopy is NFPA 701 fire-rated and uses a Kevlar ratchet strap system that keeps everything locked down in wind and wet conditions. The Joramoy is fine for light rain with the flaps rolled up for airflow, but the manufacturer itself recommends placing the generator under a covered area for heavy rain and using the cover as an additional layer. I wouldn’t risk the Joramoy in a downpour.
Is the GenTent worth the extra money over the Joramoy?
Yes, if you run your generator in serious weather regularly. The GenTent costs more because it uses fire-rated materials (NFPA 701 and UL V-0 flame-retardant), a patented strap system that doesn’t require tools, and it’s designed to handle snow, sleet, and sub-zero temperatures without cracking. The Joramoy is a great budget pick at a fraction of the cost, but it’s a basic Oxford fabric tent with Velcro closures — it won’t hold up to the same conditions. For occasional light rain, the Joramoy is enough.
Will the Joramoy cover fit my Honda EU2000i?
Yes, it should fit perfectly. The Joramoy measures 21.7 x 13.8 x 17.4 inches and is specifically listed as compatible with the Honda EU2000i, EU2200i, and EU2200IC. I tested it on my EU2200i and it fit snugly with room for the adjustable drawstrings to tighten around the bottom. Just measure your generator before buying to be safe — the specs are right in the product description.
Can I refuel my generator without removing the GenTent cover?
Yes, that’s one of the best features of the GenTent. It has a large access door that lets you reach the fuel cap and oil fill without taking the whole cover off. This is a huge advantage in wet weather because you don’t have to expose the generator to rain while refueling. The Joramoy doesn’t have a dedicated refueling door — you’d have to roll up a side flap or remove the cover entirely.
Which cover is easier to install — Joramoy or GenTent?
The Joramoy is faster to put on since it’s just a fitted tent with Velcro closures and drawstrings — you can have it on in under a minute. The GenTent takes a few minutes longer because you need to route the Kevlar ratchet straps around the generator frame and tighten them down. But the GenTent’s straps are tool-free and once they’re set, the cover is much more secure and won’t blow off in wind. I’d trade the extra two minutes for the peace of mind.
Can I use either cover for storage, or are they only for running the generator?
Both covers work for storage and running. The Joramoy is actually marketed as a dual-purpose cover — you can use it while the generator is running with the flaps open, or close it up completely for storage against sun and dust. The GenTent is primarily designed for running, but you can adapt it into a full storage cover by adding the GenSkirt accessory. If you mainly need a storage cover and only occasionally run in rain, the Joramoy is the better value.
My Final Verdict
The GenTent Inverter Running Cover is my overall winner for anyone who runs their Honda EU2000i or EU2200i in real wet weather. The NFPA 701 fire-rated vinyl canopy and Kevlar ratchet strap system make it the only cover I’d trust in heavy rain, snow, or wind without worrying about safety or the cover blowing off. The Joramoy is a solid runner-up for budget-minded buyers who only need occasional light rain protection and want a lightweight 0.43 kg cover that doubles as storage.
If you’re on the fence, ask yourself this: how often do you actually run your generator in the rain? If it’s more than a few times a year, the GenTent’s fire-rated materials and secure mounting are worth every penny. If it’s a rare emergency or camping trip where you can add overhead shelter, save your money and grab the Joramoy.
