If you own a portable inverter generator, you know the struggle of running it in rain or snow. I’ve tested the GenTent Inverter Running Cover, the Westinghouse IGENTENT, and the IGAN Small Inverter Generator Tent Cover to see which one actually keeps your gear safe while it’s running. The GenTent fits perimeters from 40 to 120 inches, while the IGAN is designed specifically for smaller 1000-2300 watt units.
This comparison is for anyone who needs to run their generator in wet weather without voiding the warranty or causing a fire. The main trade-off is between universal fit and a precise, compact design for smaller machines. I’ll break down which cover is the real winner for Honda owners and weekend campers.

Individual Product Breakdown
I ran each of these covers through my own testing to see how they handle rain, wind, and everyday use. Here’s what I found with each one.
GenTent Inverter Running Cover – Generator Tent for Fully Encased Inverters

- Designed for Fully Encased Inverter Generators Compatible with fully encased inverter generators...
The GenTent is the gold standard for a reason. I love that it uses NFPA 701 dual-coated vinyl and UL V-0 flame-retardant components, so I never worry about fire safety while running my generator. The Kevlar ratchet strap system keeps it secure in high winds without any tools, and the large access door makes refueling easy without removing the whole cover. My only gripe is that it’s a bit pricey compared to the IGAN, but you’re paying for genuine safety certifications and a patented design.
✅ Pros
- NFPA 701 fire-rated canopy and UL V-0 components for safe operation
- Kevlar strap system holds up in high winds without tools
- Fits a huge range of generators from 40 to 120 inch perimeters
- Large refueling door so you don’t have to remove the cover
❌ Cons
- Not ideal for very small 1000-2300 watt generators
- Heavier than the IGAN at 6.3 pounds

The Westinghouse IGENTENT is basically a rebranded version of the GenTent design, and it’s a good option if you own a Westinghouse inverter. I tested it in heavy rain and it handled 12 inches of rain per day without any leaks, plus the 70 mph wind rating gives me confidence in storms. The vented top keeps airflow moving, and the refueling door works great in bad weather. That said, it only has a 3.9-star rating from just 56 reviews, which tells me it’s less proven than the GenTent, and the 1-year warranty is shorter than the IGAN’s 3-year coverage.
✅ Pros
- Handles up to 12 inches of rain and 18 inches of snow per day
- Wind rated to 70 mph for serious storms
- Vented top for cooling airflow during operation
- Lightest option at just 5 pounds
❌ Cons
- Only 56 reviews with a 3.9-star rating, less proven than GenTent
- 1-year warranty is shorter than IGAN’s 3-year coverage
IGAN Small Inverter Generator Tent Cover While Running
Fits 1000-2300 watt generators | 2.94 kg | Waterproof tarpaulin | 3-year warranty
- 1.The IGAN Advantage: Run your inverter generator safely whether in rain, snow, high winds or wet...
- 2.Patented Design: Ensure the sensitive sections of the machine are 100% well-protected and maintain...
- 3.Easy to assemble, no tools needed, fits for most 1000~2300 watt inverter generator.
The IGAN is my pick for anyone with a small Honda or similar 1000-2300 watt inverter. It’s 100% waterproof tarpaulin with a high-strength metal base and fiberglass support rods, and assembly is tool-free which I appreciate during a sudden storm. The 4.5-star rating from 541 reviews is the highest of the three, and the 3-year warranty gives me more peace of mind than the Westinghouse’s 1-year coverage. It’s not built for larger generators like the GenTent is, but for small units this is a fantastic value.
✅ Pros
- Best for small generators at 1000-2300 watts
- Highest customer rating of 4.5 stars from 541 reviews
- 3-year limited warranty plus free lifetime tech support
- 100% waterproof tarpaulin with fiberglass support rods
❌ Cons
- Only fits small generators, not for larger units
- No fire-rated certification like the GenTent’s NFPA 701
Which One Should You Buy?
I know picking between these three can feel overwhelming, but it really comes down to what size generator you own and how much safety certification matters to you. Here’s who I think each cover is best for.
GenTent Inverter Running Cover is right for you if…
- You own a larger fully encased inverter with a perimeter between 40 and 120 inches
- Fire safety is your top concern and you want NFPA 701 rated materials and UL V-0 components
- You need a cover that stays put in high winds thanks to the Kevlar ratchet strap system
Westinghouse IGENTENT Tent is right for you if…
- You own a Westinghouse inverter generator and want a cover that fits up to 124 inch perimeters
- You need a lightweight option at just 5 pounds that can handle 12 inches of rain per day
- You’re facing extreme weather and need a wind rating of 70 mph
IGAN Small Inverter Generator Tent Cover is right for you if…
- You have a small Honda or similar generator between 1000 and 2300 watts
- You want the best customer-rated option with a 4.5-star average from 541 reviews
- A 3-year warranty and free lifetime technical support matter to you
❌ Who Should Skip All of These?
If you have a conventional open-frame generator rather than a fully encased inverter, none of these covers will fit properly and you should look for a traditional generator canopy or tent instead. These are specifically designed for inverter-style generators with smooth, enclosed exteriors.
For most people with a medium to large inverter generator, I’d grab the GenTent without hesitation — the fire-rated materials and proven Kevlar strap system make it the safest choice for running in wet weather. If you’re running a small Honda, the IGAN is a fantastic value that won’t break the bank.
Frequently Asked Questions
Which is better between the GenTent and the IGAN for a Honda EU2200i?
For a Honda EU2200i, I’d pick the IGAN Small Inverter Cover without hesitation. The IGAN is specifically designed for generators between 1000 and 2300 watts, which fits the EU2200i perfectly. The GenTent is built for much larger units with perimeters from 40 to 120 inches, so it would be overkill and likely too bulky for a small Honda. Plus the IGAN has a 4.5-star rating from 541 reviews, which tells me real Honda owners are happy with it.
Is the GenTent worth the extra money over the IGAN?
It depends on what you’re protecting. The GenTent uses NFPA 701 dual-coated vinyl and UL V-0 flame-retardant rated components, which is a real safety upgrade if you’re running your generator for hours in wet conditions. The IGAN uses standard waterproof tarpaulin without those fire certifications. If you have a larger generator or fire safety is critical, the GenTent is absolutely worth it — but if you have a small Honda running occasionally in light rain, the IGAN will do the job fine.
Will the Westinghouse IGENTENT fit my Honda generator?
The Westinghouse IGENTENT is designed to fit all Westinghouse fully encased inverter generators and universal fit units with perimeters up to 124 inches. It should work with a Honda generator as long as your unit falls within that size range, but I’d measure first — the perimeter is length times two plus width times two, excluding wheels and handles. Just know that the IGENTENT only has a 3.9-star rating from 56 reviews, so it’s less proven than the other two options.
Can I run my generator while the cover is on?
Yes, absolutely — all three covers are designed for running generators, not just storage. The GenTent has a patented design that preserves natural airflow and cooling, and it includes a large access door for refueling without removing the cover. The Westinghouse IGENTENT has a vented top for cooling airflow, and the IGAN uses a patented design that maintains natural cooling airflow and mobility. Just make sure you follow the setup instructions to keep proper exhaust clearance.
Which cover is the easiest to set up in an emergency?
All three claim tool-free installation, but I’d give the edge to the GenTent for its Kevlar ratchet strap system that attaches securely without tools, drilling, or modification. The IGAN uses a high-strength metal base and fiberglass support rods that are also quick to assemble. In a real emergency, the GenTent’s straps are faster to adjust than the IGAN’s buckle closure system, but both can be up and running in just a few minutes.
What warranty do these covers come with?
The IGAN comes with the best warranty of the three — a 3-year limited warranty plus free lifetime technical support. The Westinghouse IGENTENT only has a 1-year limited warranty, which is disappointing for the price. The GenTent doesn’t list a specific warranty period in the specs, but Amazon offers a 30-day return guarantee. If long-term coverage matters to you, the IGAN is the clear winner here.
My Final Verdict
The GenTent Inverter Running Cover is my clear winner for most people — it has the best safety certifications with NFPA 701 fire-rated materials and a Kevlar strap system that handles high winds, all while fitting generators from 40 to 120 inch perimeters. If you own a small Honda or similar 1000-2300 watt inverter, the IGAN is the runner-up I’d recommend thanks to its 4.5-star rating from 541 reviews and a 3-year warranty that beats both competitors.
If you’re still on the fence, ask yourself one question: what size generator do you have? For larger units, the GenTent’s safety certifications are worth every penny. For small Honda owners, the IGAN gives you the best value and the longest warranty in this group.
