How We Chose These Pulsar Generator Covers
No product in this guide was personally tested. The ranking was compiled from published manufacturer specifications, retailer listings, and compatibility lists that name Pulsar models or Pulsar wattage ranges. Scores are assumed editorial estimates, not measured results.
What we compared
10 covers with stated dimensions, materials, and Pulsar compatibility, checked against published listings for fit, weather protection, and ease of use.
Our 3 scoring criteria
Fit and Pulsar Compatibility, Weather Protection and Durability, and Ease of Use and Storage, each scored out of 5 as an editorial estimate.
What we did not do
No hands-on testing, no rain or wind trials, and no consultation with a named expert. Do not read any score as a laboratory result.
What we left out — and why
Covers with no stated dimensions or no Pulsar compatibility mention were left out, because fit cannot be judged from a name alone.
What to Look for When Buying a Pulsar Generator Cover
A cover fails in two ways: it does not fit, or it is the wrong type for how you use it. Get the size and the running-versus-storage choice right first, then judge material and fastening.
1. Measure Before You Buy — Fit and Pulsar Compatibility
Measure length, width, and height with wheels, handles, and exhaust included, then compare those numbers with the cover size, not with wattage alone. A 5000W Pulsar and a 5000W model from another brand can have different frames. Check that the listing names your Pulsar model or wattage range. If you are also choosing the generator itself, compare the best Pulsar portable generators first, so the cover matches the unit you own.
2. Storage Cover vs Running Cover
A storage cover is for a cool, switched-off generator. A running cover is built with a frame, clearance, and ventilation so the generator can operate under it. Never use a storage-only cover while the generator is running, because heat and exhaust need a clear path. Decide which job you need before you shop, because a cover that is good at one job is often unsafe at the other.
3. Material and Weather Protection
Look for a stated fabric weight, such as 600D or 900D polyester or Oxford fabric, plus a waterproof coating and UV resistance. Thicker fabric usually handles wind, sun, and abrasion better, but it is also heavier and harder to fold. Seams, zippers, and vents matter as much as the main fabric, because water finds the weakest point first. Choose covers built for weather protection if your generator stays outside for weeks at a time.
4. Securing, Ventilation, and Long-Term Storage
Check for an elastic hem, drawstring, or buckle straps that hold the cover in wind without crushing vents or controls. Air vents help reduce trapped moisture during storage, but they must not let rain in. Store the generator dry, cool, and off the ground when possible, and let it cool fully before covering it. For a full storage routine, read about generator covers for storage before you put the unit away for the season.
Pulsar Heavy-Duty Generator Cover PGC12A1 — Direct Pulsar Fit
Best for: Pulsar 5000-12000W open-frame generators
If you own a Pulsar open-frame generator, this Pulsar-branded cover removes the guesswork that comes with universal sizes. It is sized at 31 by 21 by 23 inches for Pulsar models from 5000 to 12000 watts, so the fit is specific rather than approximate. Heavy-duty polyester resists water and ultraviolet damage, while the zipper closure keeps the cover in place during storage. It is a storage cover, not a running cover, so the generator must be cool and switched off before you fit it. For owners who want a direct Pulsar match, that specificity is the main reason to choose it over a generic alternative.
- Pulsar-branded fit for 5000-12000W models
- Heavy-duty waterproof polyester with UV resistance
- Zipper closure holds cover securely
- One-year limited warranty included
- Storage only, never use while running
- Single size, no smaller Pulsar option
- Heavier fabric takes longer to fold

IGAN Generator Cover While Running for 3500-12000W Generators — Rain-Ready Running Cover
Best for: Running a Pulsar in rain
If you need power during a storm, this IGAN cover is built for that job, not just for storage. Its waterproof tarpaulin sits on a 5/8-inch stainless steel frame, creating clearance around the generator so heat and exhaust can escape while rain stays out. At 33 by 25.5 by 18.5 inches, it fits tubular and square-frame generators from 3500 to 12000 watts, which covers many larger Pulsar models. It weighs 9 lb and doubles as a storage cover when the generator is off. That running design is the main trade-off: it is bulkier and slower to set up than a simple storage cover.
- Waterproof tarpaulin frame cover for running use
- Stainless steel frame, 9 lb total
- Doubles as storage cover
- Three-year limited warranty included
- Heavier and bulkier than storage covers
- Frame setup takes extra time
- Costs more than simple storage covers

Porch Shield Waterproof Universal Generator Cover 25 x 24 x 21 Inch — Simple Budget Storage
Best for: Budget storage for 3000-5000W Pulsar generators
If you want straightforward storage protection without a running-cover frame, this Porch Shield cover is the simplest choice in this list. It uses 600D polyester with a waterproof backcoating, and its 25 by 24 by 21 inch size fits many 3000 to 5000 watt generators, including listed Pulsar models. An elastic hem pulls it snug around the base, so fitting takes seconds and folding it away is just as quick. It is storage only, so never run the generator with it on. For a smaller Pulsar kept in a garage, shed, or covered porch, that simplicity is the main advantage.
- 600D polyester with waterproof backcoating
- Fits 3000-5000W Pulsar models
- Elastic hem for quick fitting
- Light and easy to store
- Storage only, never use while running
- Single size limits larger Pulsar models
- No buckle straps for high wind

GenTent Generator Running Cover Universal Kit Standard Grey GTOPFUASGR — Storm Running Kit
Best for: Open-frame Pulsar generators in storms
If you run an open-frame Pulsar through heavy rain, this GenTent kit is designed around clearance and airflow, not just a waterproof shell. Its NFPA-rated ripstop vinyl covers the top and sides while frame rods hold it away from hot parts, so the generator can keep running in a storm. At 36 by 24 by 18 inches, with a perimeter range of 76 to 104 inches, it fits open-frame models from 3500 to 10000 watts. The kit includes rods and hardware, which adds setup time. For storm use, that structured design is the main reason to choose it over a loose storage cover.
- NFPA-rated ripstop vinyl for storm use
- Frame rods create safe running clearance
- Fits 3500-10000W open-frame models
- Hardware kit included in box
- Setup takes longer than simple covers
- Not suited to small inverter generators
- Bulkier to store when packed away

Porch Shield Generator Cover While Running 36 x 28 x 20 Inch — Large Running Cover
Best for: Large Pulsar generators running in rain
If your Pulsar is too large for the common 25-inch storage covers, this Porch Shield running cover gives you more room without moving to a framed tent. At 36 by 28 by 20 inches, it fits generators from 3500 to 12000 watts, including listed Pulsar models, and it can be used for both storage and running. Its 600D polyester has a PVC waterproof backcoating, so rain beads off rather than soaking through. Check the frame shape and exhaust position before running, and follow the maker guidance on clearance. For a large generator that must run in wet weather, that size range is the main advantage.
- Large 36-inch size for 3500-12000W models
- 600D polyester with PVC waterproof backcoating
- Works for storage and running use
- Lists Pulsar compatibility in listings
- Too large for small inverter generators
- Check exhaust clearance before running
- Heavier than smaller storage covers

Kaskawise Outdoor Generator Cover 26 x 20 x 20 Inch — Heavy-Duty Storage Cover
Best for: Pulsar PG12000B and 3500-6000W models
If your Pulsar sits outside for long periods, this Kaskawise cover uses thicker 900D Oxford fabric with a waterproof coating, which should handle sun, rain, and scuffs better than lighter storage covers. At 26 by 20 by 20 inches, it fits generators from 3500 to 6000 watts and lists the Pulsar PG12000B in its compatibility information. Buckle straps hold it in wind, an air vent helps reduce trapped moisture, and a carry bag keeps it tidy when folded. It is a storage cover, so never run the generator with it on. For exposed outdoor storage, that heavier fabric is the main reason to choose it.
- 900D Oxford fabric with waterproof coating
- Lists Pulsar PG12000B compatibility
- Buckle straps hold cover in wind
- Air vent and carry bag included
- Storage only, never use while running
- Heavier fabric is harder to fold
- Check PG12000B dimensions before buying

NGB Generator Running Cover 24.8 x 20.2 x 20.8 Inch — Inverter Running Cover
Best for: Pulsar 5250 and other inverter generators
If you run a smaller Pulsar inverter in rain, this NGB cover is sized for that smaller frame, not for a large open-frame unit. Its double layer uses a 600D outer and a 210D inner, with a waterproof top that allows refuelling access while the cover stays in place. At 24.8 by 20.2 by 20.8 inches, it lists the Pulsar 5250 among its compatible models, so check your inverter dimensions before buying. It can be used for running and storage, but always follow the maker guidance on ventilation and exhaust clearance. For inverter owners who need rain cover while running, that compact fit is the main advantage.
- Double layer: 600D outer, 210D inner
- Lists Pulsar 5250 compatibility
- Waterproof top for refuelling access
- Works for running and storage
- Too small for large open-frame generators
- Check exhaust clearance before running
- Double layer adds weight and bulk

GEHENG Generator Cover While Running 28 x 20 x 20 Inch — Ventilated Running Cover
Best for: Pulsar 4000 and 3000-5000W generators
If ventilation is your main concern while running in rain, this GEHENG cover is built around airflow as well as waterproofing. It uses 900D Oxford fabric, with an EVA window and ventilation openings that help heat escape while the cover stays in place. At 28 by 20 by 20 inches, it fits generators from 3000 to 5000 watts and lists the Pulsar 4000 among its compatible models. A storage bag is included, so it packs away neatly when not in use. Check exhaust position and clearance before running, because ventilation only helps when the cover is fitted correctly.
- 900D Oxford fabric for durability
- EVA window and ventilation openings
- Lists Pulsar 4000 compatibility
- Storage bag included
- Check exhaust clearance before running
- Too small for large Pulsar models
- Ventilation needs correct fitting

It uses 600D heavy-duty waterproof fabric, and its 25 by 24 by 21 inch size fits many 3000 to 5000 watt generators, including listed Pulsar models. An elastic bottom cord pulls it snug, so you can fit it in seconds and remove it just as fast. It is storage only, so never run the generator with it on, and it has no buckle straps for very windy sites. For a smaller Pulsar kept indoors or under cover, that simplicity is the main advantage.
- 600D heavy-duty waterproof fabric
- Fits 3000-5000W Pulsar models
- Elastic bottom cord for quick fitting
- Simple design, no extra parts
- Storage only, never use while running

Joramoy Generator Cover 20 x 11.5 x 16 Inch — Small Inverter Storage Cover
Best for: Pulsar G2319N and small inverters
If you own a small Pulsar inverter, a standard 25-inch cover will hang loose and catch wind, so this Joramoy cover is sized for that smaller frame. At 20 by 11.5 by 16 inches, it fits the Pulsar G2319N and other small inverters with similar dimensions. Its 420D Oxford fabric has a PVC coating for water resistance, and an elastic drawstring pulls it snug around the base. It is storage only, so never run the generator with it on. For a compact inverter kept in a garage, car, or small shed, that close fit is the main advantage.

Who These Pulsar Generator Covers Are NOT For
These covers are sized for Pulsar models and wattage ranges listed in this guide. They are not a universal answer for every generator, every climate, or every running setup.
If your generator is not a Pulsar, or its dimensions fall outside the sizes listed here, measure it and choose a cover by dimensions, not by this list. If you need a custom standby cover for a fixed home unit, a portable cover will not fit correctly.
Common Mistakes to Avoid
Most cover problems come from size, type, or storage habits, not from the fabric alone.
Frequently Asked Questions About Pulsar Generator Covers
What size cover do I need for a Pulsar generator?
Measure your Pulsar generator in length, width, and height, including wheels, handles, and the exhaust, then choose a cover at least that large in all three dimensions. Wattage alone is not enough, because models with the same watts can have different frames. Check that the listing names your Pulsar model or wattage range, and leave a small margin so the cover fits without stretching.
Can you run a Pulsar generator with a cover on?
You can run a Pulsar generator only under a cover made for running, with the clearance and ventilation the maker specifies. Never run it under a storage-only cover, because heat and exhaust need a clear path. Check the exhaust position, keep the cover away from hot parts, and place the generator outdoors in a safe location. For overnight plans, read the guidance on running a generator overnight safely first.
Are Pulsar generator covers waterproof?
Most covers in this guide are described as waterproof or water-resistant, but that does not mean every seam, zipper, or vent is fully sealed. A waterproof coating protects the main fabric, while water can still enter through gaps if the cover is loose or damaged. Choose a cover with a stated waterproof coating, fit it snugly, and check it after heavy rain for trapped water underneath.
How do I measure my Pulsar generator for a cover?
Use a tape measure on the generator itself, not on the box or a photo. Measure the longest length, the widest width, and the tallest height, including wheels, handles, and any protruding parts. Write down all three numbers, then compare them with the cover size in the listing. If your generator falls between two sizes, choose the larger cover so it does not stretch or press against controls.
What is the difference between a storage cover and a running cover?
A storage cover is for a cool, switched-off generator, and it fits close to the frame to keep out dust, rain, and sun. A running cover is built with a frame, clearance, and ventilation so the generator can operate under it without trapping heat or exhaust. The two types are not interchangeable. If you need power in rain, buy a running cover; if you only need protection between uses, buy a storage cover.
How do I keep a generator cover from blowing off?
Choose a cover that fits closely, then tighten its elastic hem, drawstring, or buckle straps every time you fit it. A cover that is too large will catch wind and flap, which can tear the fabric or pull it off completely. Store the generator in a sheltered spot when possible, and check the straps after strong wind. Replace a cover once the elastic or straps no longer hold it snugly.
Our Final Verdict
The main choice is fit first, then running versus storage. The Pulsar-branded PGC12A1 is the clearest storage pick for larger Pulsar models, while the IGAN and GenTent covers are the safer choices for running in rain. Measure your generator, pick the right type, and do not use a storage cover while running.
