The WEN 56200iC is a universal weatherproof generator cover engineered to protect inverter generators ranging from 1,600 to 2,500 watts. This cover is ideal for camping enthusiasts, RV owners, and anyone who relies on portable power and wants to extend their generator's lifespan by shielding it from harsh weather conditions and environmental damage.
The standout feature is the dual-material construction: a high-grade UV and water-resistant vinyl exterior tackles rain, snow, hail, sleet, and intense sun exposure, while the soft cotton interior lining prevents scratches and scuffs during storage and transport. The universal fit with adjustable elastic-banded base and drawstring closure accommodates generators up to 11 x 20.5 x 18 inches, making it compatible with six WEN inverter generator models including the 56225i, 56200i, 56202i, 56203i, GN400i, and 56235i.

The drawstring mechanism is intuitive and secure, with a cord lock that keeps the cover firmly in place even in light winds. The cover weighs just 8 ounces, making it convenient to store in vehicles or RVs without adding significant bulk.
The main limitation is the lack of dedicated storage pockets for small accessories like oil bottles or maintenance tools, which some users wish were included. Additionally, while early reviews are very positive, long-term durability data over multiple seasons of outdoor exposure is still being collected by the user community.
Overall, the WEN 56200iC delivers excellent protection and durability at an affordable price point. If you own a compatible WEN inverter generator or have a portable generator within the specified dimensions, this cover is a smart investment that will keep your equipment safe from the elements and looking like new for years to come.

Who Should Buy This Cover? This cover is perfect for WEN inverter generator owners who want reliable weather protection. It's especially valuable for those who store generators outdoors, use them during camping or RV trips, or keep them in vehicles where they may be exposed to dust, dirt, and moisture.

Installation Tips: Always allow your generator to cool completely before covering it. Never place the cover on a running or hot generator, as this can cause damage. The drawstring should be tightened enough to hold the cover securely in wind, but not so tight that it strains the vinyl.
Maintenance: Periodically remove the cover and inspect for any damage or debris accumulation. For cleaning, use a soft cloth and mild soap with water. Avoid harsh chemicals or abrasive scrubbing that could damage the vinyl coating.
Storage: When not in use, store the cover in a dry location away from direct sunlight. This will extend its lifespan and ensure it remains ready to protect your generator whenever needed.

How to Choose the Right Generator Cover
Confirm the Correct Dimensions
The most critical step is measuring your generator. Note its length, width, and height. Compare these numbers directly to the cover’s internal dimensions, not its wattage rating. A proper fit prevents flapping in the wind and ensures complete coverage. Always allow for a little extra space, especially if your unit has protruding handles or fuel caps.
Prioritize Material and Weather Resistance
Look for covers made from durable, water-repellent fabrics like vinyl or heavy-duty Oxford cloth. These materials resist tears and block moisture from rain and snow. UV resistance is equally important to prevent the fabric from degrading and cracking in direct sunlight over time. A quality material is your generator’s first line of defense.
Consider Ventilation and Accessibility
<!–Proper ventilation is crucial to prevent condensation and moisture buildup underneath the cover, which can cause rust. Some models include mesh panels or ventilation openings. Also, consider how easy it is to put on and take off. Features like a full-length zipper or roll-up straps with fasteners can make accessing your generator much more convenient. Pairing your cover with other accessories, like a generator exhaust extension kit, can create a complete protection system.
Final Thoughts
For reliable and affordable generator protection, our assessment confirms two standout choices. If you own a popular inverter model, the WEN 56200iC Universal Weatherproof Inverter cover offers a tailored, high-rated fit with excellent material quality. For those with larger conventional portable generators, the Portable Generator Rain Cover Waterproof from Rimwig provides robust coverage with smart features like ventilation and secure straps, making it a versatile pick for varied outdoor conditions. Both ensure your power source remains ready when you need it most.
Frequently Asked Questions
Can I use a tarp instead of a dedicated generator cover?
While a tarp offers basic rain protection, it lacks a tailored fit and secure fastenings. Tarps often trap moisture, promote condensation, and can blow away easily. A purpose-built cover with ventilation, waterproof fabric, and snug straps provides far superior, long-term protection for your investment, especially for portable generators stored outside.
How do I know what size cover to buy?
Always measure your generator’s length, width, and height first. Compare these exact dimensions to the interior measurements listed for the cover. Do not rely solely on wattage ratings, as physical sizes can vary between brands and models. Choosing a cover with dimensions slightly larger than your generator ensures a proper fit over handles and controls.
Is it safe to cover a generator while it’s still warm?
No, you should never cover a generator immediately after use. Allow the unit to cool down completely to ambient temperature. Covering a hot engine traps heat and exhaust fumes, which can be a fire hazard and cause damage to the cover material. Always ensure the generator is cool and dry before putting on its protective cover.
Will a cover protect my generator in winter storage?
A high-quality, weatherproof cover is excellent for winter protection. It shields the unit from snow, ice, and freezing rain. Look for covers with water-repellent fabric and secure straps to handle winter winds. For comprehensive seasonal preparation, also consider using a fuel stabilizer and storing your generator in a dry, sheltered location if possible, alongside other protective generator accessories.
Evaluate Secure Fit Features
<!–A cover that blows away is useless. Features like adjustable drawstrings, elastic hems, and Velcro straps at the bottom are essential. They cinch the cover snugly around your generator’s base, minimizing movement during high winds. This secure fit ensures the protection stays in place through storms and gusty days.
