Buying Guide for Best Generator Storage Covers
Size and Fit
The first step in choosing a generator storage cover is measuring your unit precisely: length, width, and height. A snug fit prevents water pooling and wind lift, crucial for gardeners storing generators near vegetable patches where gusts can scatter debris. For example, the Champion Power Equipment Weather-Resistant Storage Cover for 4800-11,500-Watt Portable Generators fits up to 30.7 x 23.6 x 23.6 inches, making it ideal for mid-sized models used in lawn aeration or hedge trimming.
Universal covers like the Porch Shield Waterproof Universal Generator Cover in 32 x 24 x 24 inch offer flexibility for various brands such as Champion or Westinghouse. Always add a couple of inches for airflow, especially if you store in a damp garden shed. Tip: Place your generator on a flat, elevated surface under the cover to avoid ground moisture.

Material and Durability
Look for heavy-duty materials like 600D polyester or vinyl with waterproof coatings to withstand garden exposure to tree sap, pollen, and soil splatter. The Porch Shield models use 600D polyester with laminated backcoating, providing tear resistance that holds up against branches or tools bumping into it during storage.
Champion Power Equipment covers feature tough vinyl exteriors that block UV damage, perfect for generators parked in sunny patios. For extra ruggedness, consider options with double stitching like Porch Shield, which seal seams against prolonged moisture from sprinkler runoff.
| Material Type | Durability Benefit | Gardener Tip |
|---|---|---|
| 600D Polyester | Tear-resistant, waterproof | Great for windy sites near tall hedges |
| Vinyl | UV protection | Ideal for full-sun lawn storage |
| Heavy Duty Tarpaulin | Extreme weather hold | Best for coastal gardens with salt air |
Weather Resistance
Superior weatherproofing keeps rain, snow, and sun from corroding your generator, vital when powering pumps during storms. Covers like the IGAN Generator Covers While Running boast 100% waterproof tarpaulin and stainless steel frames, though primarily for storage too.
Elastic hems and straps on Champion and Porch Shield models ensure a secure fit during high winds common in open backyards. Gardeners in variable climates should prioritize UV-resistant coatings to prevent fading and cracking over seasons.
Pro tip: After garden use, clean the cover exterior with mild soap to maintain its water-repellent properties.
Ventilation and Accessibility
Even in storage, some airflow prevents mold, especially in humid garden environments. Models with zippers or roll-up panels, like the Champion for inverter generators, allow handle access without full removal.
The Porch Shield features Velcro and stacked fabric for ventilation while staying weather-tight. For gardeners checking oil levels seasonally, quick-access designs save time during fall prep.
Brand Compatibility and Versatility
Match covers to popular garden generators from Champion, Honda, or Westinghouse. Versatile options like Porch Shield fit 5000-10000 Watt models across brands, simplifying choices for multi-tool setups.
Champion’s sized-specific covers ensure custom fits, reducing wear. Check our Outdoor Generator Covers page for size charts.
Windproof Features
Elastic cords, bottom straps, and weighted designs combat gusts near open lawns. IGAN and GenArmor use metal frames for stability, though best for stationary storage.
For portable use post-gardening, lighter fabric covers like Champion slip on quickly.
