The Joramoy Generator Cover is a heavy-duty protective solution designed for owners of compact inverter generators, particularly Honda EU2000i and EU2200i models, as well as compatible units from Westinghouse, Ryobi, Yamaha, and other brands. This cover targets homeowners, contractors, and outdoor enthusiasts who need reliable weather protection and security for portable power equipment stored in garages, sheds, or outdoor spaces.
The standout feature is the 420D Oxford fabric with 100% waterproof PVC coating, which provides comprehensive protection against rain, snow, UV rays, dust, tree sap, and bird droppings. The elastic hem cord and buckle strap system creates a snug, custom fit that remains secure even in heavy wind and storms. The cover's compact 20L x 11.5W x 16H inch dimensions make it ideal for standard portable generators without adding bulk to storage areas.
Build quality appears solid with reinforced stitching and durable materials designed for outdoor durability. The practical design includes a tool pocket for storing accessories and a top handle cutout that allows you to access the generator's carry handle without removing the cover entirely. The intentional lack of prominent branding distinguishes this cover from competitors and serves a security purpose by making the covered item less obviously a generator to potential thieves.
One limitation is the absence of verified customer reviews, which means real-world durability data over extended periods is unavailable. Additionally, the fixed dimensions mean this cover is best suited for generators in the 2000-2500W range and may not accommodate larger portable models. The black color, while aesthetically neutral, can absorb heat in direct sunlight, which may impact cover longevity if exposed year-round without shade.
The Joramoy Generator Cover is a solid choice for protecting mid-size inverter generators with quality materials and practical features. The combination of waterproof protection, secure fit, and discreet design makes it particularly valuable for users prioritizing both equipment longevity and theft prevention.

How to Choose the Right Inverter Generator Cover
Material and Weatherproofing
The fabric’s denier rating, like 600D or 420D, indicates its thickness and durability. Higher denier fabrics generally offer better tear resistance. Look for terms like “waterproof undercoating” or “PVC coating” for true water protection, not just water resistance.
A vinyl exterior or oxford cloth with a laminated layer effectively blocks UV rays, preventing sun damage and material degradation. Double-stitched seams are a hallmark of quality, ensuring the cover withstands wind and does not unravel over time.
Fit and Security Features
An improper fit can leave gaps for moisture or flap in the wind, causing abrasion. Always measure your generator’s length, width, and height before purchasing. The best covers offer a snug, custom-like fit through elastic hems, drawstrings, or adjustable straps.
Features like a zippered panel for the carry handle or a dedicated refueling door add tremendous convenience. They allow you to move or maintain your generator without removing the entire cover, a major advantage during inclement weather. This is especially useful for emergency inverter generators that may need to run for extended periods.
Intended Use: Storage vs. Running
This is the most critical distinction. Standard storage covers are only for use when the generator is completely off and cool. They protect from environmental elements but block all ventilation.
Running covers, often called generator tents, are engineered for safe operation. They feature roll-up sides or mesh panels for critical airflow and heat dissipation while shielding the control panel and engine from rain. Never use a standard storage cover on a running generator, as it poses a severe fire and overheating risk. Safety is paramount, just as it is with portable generators with CO shutdown technology.
Additional Practical Features
<!–Consider extras that enhance usability. Integrated storage pockets for power cords, tools, or fuel bottles keep accessories organized and dry. A cotton or soft fabric interior lining prevents scratches on your generator’s finish.
For maximum durability, look for reinforced stress points and rust-resistant zippers or clasps. A included storage bag makes it easy to stow the cover when not in use, keeping it clean for the next application. You can find more gear for your power setup on our main inverter generators page.
Final Thoughts
Investing in a dedicated cover is a smart move to extend the life and reliability of your inverter generator. For most users seeking dependable storage protection, the WEN 56310iC Universal Weatherproof Inverter offers excellent value with its proven vinyl construction. If you require the ability to operate your generator safely in rain or snow, the innovative NGB Generator Runing Cover 24.8L x 20.2Wx 20.8H with its roll-up sides and refueling door is a standout solution.

Frequently Asked Questions
Can I use a tarp instead of a generator cover?
While a tarp provides basic coverage, it is not recommended. Tarps lack a secure fit, often flap in the wind causing abrasion, and trap moisture against the generator, promoting rust and mold. A purpose-built cover with waterproof, breathable materials and a snug fit offers far superior protection.
How do I clean my inverter generator cover?
Most covers can be cleaned with mild soap, lukewarm water, and a soft brush. Gently scrub the surface and rinse thoroughly. Always allow the cover to dry completely before folding and storing it to prevent mildew. Check the manufacturer’s instructions for specific care recommendations.
What size cover do I need for my generator?
Accurately measure your generator’s dimensions: length, width, and height at its tallest point. Use these measurements to compare against the product’s internal dimensions listed by the manufacturer. It is better to have a slightly larger cover that can be cinched tight than one that is too small and strains at the seams.
Are all generator covers waterproof?
No, there is a key difference. Many covers are water-resistant, meaning they can shed light rain for a short period. Truly waterproof covers have a laminated undercoating or sealed seams that prevent water penetration even during heavy, prolonged rain. Always verify the product’s claimed level of water protection before buying.
