How We Chose These Suitcase Generator Covers
What we compared
10 covers from published roundups and retailer listings, focused on 2000W-2500W suitcase inverters such as Honda EU2200i and Westinghouse WH2200i.
Our 3 scoring criteria
Fit and compatibility, weather protection, and ease of use. Scores are assumed editorial estimates, not test results.
Expert consulted
No outside expert was consulted for this assumed draft. Guidance comes from manufacturer listings and published cover roundups.
What we cut — and why
Large open-frame covers for 5000W-10000W units were cut. They do not fit suitcase inverters and would hang loose in wind.
What to Look for When Buying Suitcase Generator Covers
A suitcase inverter is small, light, and easy to carry, so its cover should match that shape. A loose cover flaps, traps moisture, and wears fast. A tight cover is hard to fit and can tear at the seams.
1. Fit and Adjustability
Measure length, width, and height before you buy, then compare those numbers with the cover size, not just the wattage label. Suitcase models vary by a few inches, and that gap matters. Look for an elastic hem, drawstring, or buckles that pull the base snug. A handle opening helps you carry the unit without removing the cover. If the listing gives no dimensions, do not guess.
2. Material Quality
Most suitcase covers use 420D or 600D polyester or Oxford fabric with a waterproof coating. Heavier fabric resists tears and sun better, but it can also feel stiff in cold weather. Check for taped or sealed seams, a soft inner lining, and UV resistance if the unit sits outside. Thin vinyl can crack, while coated Oxford usually lasts longer. Our inverter generator covers guide explains how these materials differ across inverter models.
3. Safety Features
Storage covers and running covers are not the same. A storage cover must come off before you start the generator, or it can trap heat and exhaust. A running cover needs a frame, vents, and clear space around the exhaust and control panel. Never run a generator under a sealed cover or tarp. Flame-retardant fabric and open sides help, but they do not make a storage cover safe to run under.
4. Long-Term Durability
Durability shows up in stitching, fasteners, and how the cover handles sun and rain over time. Double-stitched seams, sturdy buckles, and a drawstring that still works after months matter more than a shiny coating. A storage pocket is useful for a manual or parallel cable, but it adds a seam that can leak if it is poorly made. Store the cover dry when it is not in use, and clean off dirt before folding it away.
Champion Power Equipment 100603 Storm Shield Severe Weather Inverter Generator Cover by GenTent — Runs in Bad Weather
Best for: running a suitcase inverter in rain, wind, and snow
If you need power during a storm, this is the cover to choose first. It is a framed GenTent canopy made for Champion closed-frame inverters from 2000 to 8500 starting watts, so it fits most suitcase models without pressing fabric against hot parts. The vinyl is flame-retardant and RF-welded, and the frame is rated by the maker for high wind, heavy rain, and snow. It takes more setup than a slip-on storage cover, and it costs more, but no storage cover in this list lets you run safely in the same weather.
- Framed design keeps fabric off exhaust
- Rated for 70 mph wind by maker
- Fits 2000 to 8500 starting watts
- Frame setup takes longer than slip-on
- Bulky to pack for camping trips

GenTent Inverter Generator Cover Kit — Premium Running Shelter
Best for: premium running protection for many inverter brands
This is the original GenTent inverter kit behind the Champion cover above, sold under the GenTent name for Generac, Champion, Westinghouse, DuroMax, Firman, and GENMAX inverters. It uses a strap mount, fiberglass frame, and waterproof canopy, with airflow and exhaust clearance built in. The maker lists a fit range of 40 to 120 inches in perimeter for fully encased inverters from 1000W to 11000W. It is the most flexible premium running cover here, but it needs careful measuring and a little practice to set up quickly.
- Fits many brands, not one model
- Maintains airflow and exhaust clearance
- Flame-retardant canopy, NFPA 701
- Perimeter measuring is easy to get wrong
- Premium cost for occasional use

Honda Power Equipment 08P57-Z07-00S Outdoor Storage Cover for EU2200i — Exact Honda Fit
Best for: Honda EU2200i owners who want an exact fit
This is Honda’s own outdoor storage cover for the EU2200i, so the fit is the point. It is made to follow the suitcase shape without loose fabric bunching at the corners, and the silver finish helps reflect sun during outdoor storage. It is a storage cover only, so you must remove it before starting the generator. That limits it, but for a garage, shed, or covered porch, the exact fit and simple slip-on design are hard to beat, and there is no frame to assemble or store.
- Exact fit for EU2200i shape
- Slips on in seconds, no frame
- Silver finish reflects sun heat
- Storage only, never for running
- Only fits EU2200i, not universal

BougeRV Generator Cover for Honda EU2200i — Budget Honda Storage
Best for: budget storage for Honda EU2200i and EU2000i
BougeRV gives you the Honda fit at a lower cost than the official cover. It is made from 420D polyester with a PU coating, sized at about 20.3 by 11.2 by 16 inches, and listed for EU2000i, EU2200i, EU2200IC, EU2000i Camo, and EU2000i Companion, plus a few compatible models. The maker offers an 18-month warranty and lifetime service. It is storage only, so remove it before running. For a garage or truck bed, it is a practical, low-cost way to keep dust and rain off a Honda inverter.
- 420D polyester with PU coating
- Fits EU2000i and EU2200i models
- 18-month warranty, maker stated
- Storage only, never for running
- Thinner than 600D covers

Joramoy Generator Cover for Honda EU2200i — Everyday Value Storage
Best for: everyday storage for Honda and Westinghouse inverters
Joramoy is the value version of the same Honda-sized storage cover, made from 420D Oxford fabric with a PVC coating. The size is 20 by 11.5 by 16 inches, and the listing covers Honda EU2000i, EU2200i, EU2200ic, EU2000i Camo, and EU2000i Companion, plus Westinghouse WH2000iXLT, WH2200iXLT, WH2400i, iGen2200, and iGen2500. It has an elastic hem, a top handle opening, and a large tool pocket. It is storage only, so do not run the generator with it on, but for daily dust and rain protection it is a strong value pick.
- 420D Oxford with PVC coating
- Large tool pocket with Velcro flap
- Elastic hem holds cover snug
- Storage only, never for running
- Pocket adds a seam to watch

Porch Shield Outdoor Generator Cover for Inverter Portable Generator EU2200i / EU3200 — Universal Inverter Cover
Best for: owners who switch between inverter brands
Porch Shield is the universal option in this list, made from 600D polyester with a waterproof undercoating. The size is 23 by 13 by 18 inches, and the listing covers 1500W to 2500W inverters including Honda EU2200i and EU3200i, Westinghouse iGen 2200W and 2500W, GENMAX 2000i and 3300i, Champion 2000W and 2500W, and Westinghouse WH2000iXLT, WH2200iXLT, and WH2400i. That wide fit is useful if you own more than one small inverter. It is storage only, so remove it before running, and measure first because universal still means a size range, not every model.
- 600D polyester, heavier than 420D
- Fits 1500W to 2500W inverters
- Waterproof undercoating, maker stated
- Storage only, never for running
- Loose fit on smallest inverters

PatioGem Waterproof Generator Cover for Most 2000W-2500W Outdoor Inverter Generators — Small Inverter Cover
Best for: small 2000W-2500W inverters in outdoor storage
PatioGem is made for the smallest suitcase inverters, with a size of about 20.3 by 11.2 by 16 inches. The listing covers Honda EU2000i and EU2200i, Westinghouse WH2000iXLT, WH2200iXLT, WH2400i, iGen2200 and iGen2500, Champion 2000W, and Generac 2200W models. It uses 600D Oxford fabric with a triple-layer waterproof coating and sealed seams, according to the listing. It is storage only and comes with a one-year warranty. If your inverter is at the small end of the range, this cover fits closer than a larger universal cover.
- 600D Oxford, triple-layer coating
- Sealed seams, maker stated
- One-year warranty, maker stated
- Storage only, never for running
- Too small for 3000W inverters

Akkkan Generator Running Cover, Four-Side Retractable — Budget Running Cover
Best for: budget running use with roll-up sides
Akkkan is the budget running cover in this list, made from 600D waterproof Oxford cloth with a 210D inner lining. The size is 21.7 by 13.8 by 17.4 inches, and the listing covers Honda EU2200i and EU2000i, Westinghouse 2200, WEN 56235i, GENMAX 2200W, Champion, and Pulsar G2319N models. The four sides roll up for ventilation and wiring, and the top opens for carrying. That design helps with heat and cord access, but it is still a fabric cover, so you must keep the sides open while running and check clearance around the exhaust.
- Four sides roll up for airflow
- 600D Oxford with 210D lining
- Top opens for carrying handle
- No frame, less wind stability
- Must keep sides open when running

Westinghouse WH2200i Universal Small Portable Inverter Generator Cover — Westinghouse Storage Cover
Best for: Westinghouse WH2200i owners who want storage protection
This Westinghouse cover is made from woven vinyl canvas to keep a small WH2200i clean and scratch-free in storage or transport. It has one accessory pocket for an extension cord, parallel kit, tools, or manual, plus a Velcro top flap for handle access and an elastic bottom for a secure fit. The listing says it fits most inverters measuring about 20 inches long by 14 inches wide, so it is not only for Westinghouse models. It is storage only, so remove it before running, but the pocket and handle flap make it practical for camping and travel.
- Woven vinyl canvas, scratch resistant
- Accessory pocket for cords and tools
- Velcro flap for handle access
- Storage only, never for running
- Universal fit can feel loose

Westinghouse iGenTent Generator Running Cover — Westinghouse Running Shelter
Best for: Westinghouse inverters that must run in wet weather
The Westinghouse iGenTent is the Westinghouse-branded version of the GenTent running cover, made to fully encase an inverter generator while it runs. It includes the GenTent frame, straps, and canopy parts listed in the user manual, with a one-year warranty for Westinghouse-branded models. The kit is listed for fully encased inverters with perimeters up to 124 inches, so it covers larger suitcase models too. It is the most involved cover to set up in this list, and it is best for home backup use, not quick camping trips.
- Full running cover, not storage only
- Fits perimeters up to 124 inches
- One-year warranty, maker stated
- Most involved setup in this list
- Bulky for camping and travel

Who These Suitcase Generator Covers Are NOT For
These covers are made for small, suitcase-style inverters, not for every generator you own.
If you need to run a generator indoors, in a garage, or under a sealed tarp, no cover in this list makes that safe. Generators must run outdoors, far from doors and windows, with exhaust pointed away. If you only store your unit indoors, a simple dust cover may be enough, and a framed running cover would be wasted money.
Common Mistakes to Avoid
Most cover problems come from size, running use, or wind, not from the fabric itself.
Frequently Asked Questions About Suitcase Generator Covers
Can you run a generator with a cover over it?
No, not with a normal storage cover. A storage cover traps heat and exhaust and can cause overheating or carbon monoxide buildup. You can run under a framed running cover designed for that use, with vents open and exhaust clear. Read our can you run a generator with a cover guide before you try it in rain.
What size cover do I need for a suitcase inverter generator?
Measure your generator first, then match the cover size. Most suitcase inverters in this guide are about 20 inches long, 11 to 13 inches wide, and 16 to 18 inches tall. Check length, width, and height separately, because two 2200W models can differ by inches. If your unit falls between sizes, choose the smaller snug fit for storage, not a loose oversize cover.
Are suitcase generator covers waterproof?
Most covers in this list are waterproof or highly water-resistant, with coated fabric and sealed seams. That means they shed rain and snow during storage, but no fabric cover is fully proof against standing water or pressure washing. For running use, choose a framed cover with ventilation, and keep the control panel and outlets dry even when the cover is on.
Can I leave my generator outside with a cover on?
Yes, for storage, if the cover fits snugly and the generator is cool, dry, and off. Use a waterproof cover with an elastic hem or buckles, and place the unit where water does not pool underneath. For long-term outdoor storage, check it after storms, dry the cover if it gets soaked, and store fuel safely. A cover helps, but it does not replace a shed or dry shelter.
How do I keep a generator cover from blowing off?
Choose a cover that fits closely, then secure the bottom every time. Tighten the elastic hem or drawstring, fasten any buckles or Velcro straps, and tuck excess fabric under the base. In high wind, add a bungee or strap around the lower half, and move the unit to a sheltered spot. A loose universal cover is far more likely to blow off than a snug model-specific cover.
Do I need a running cover or a storage cover?
Choose a storage cover if you only need protection between uses, in a garage, shed, or truck bed. Choose a running cover if you need power during rain or snow and cannot move the generator under shelter. Running covers cost more and need a frame, but they keep airflow and exhaust clear. If you are unsure, start with a storage cover and add a running cover only if you face storms often.
Will a universal cover fit my Honda EU2200i?
Yes, many universal covers list the EU2200i, but fit varies. The EU2200i is about 20 by 11.4 by 16.7 inches, so a cover sized at 20 by 11.5 by 16 inches fits closely. A larger universal cover may hang loose and flap in wind. For the closest fit, choose a Honda-specific cover or a universal cover that lists the exact EU2200i dimensions, not just the wattage.
Our Final Verdict
For most suitcase inverter owners, the choice is simple: buy a running cover only if you must run in bad weather, otherwise buy a snug storage cover that matches your exact dimensions. The Champion 100603 leads because it is the only cover here built to run safely in a storm.
