Buying Guide
Key considerations to help compare generator covers and choose the right one for outdoor use.
What size do you need?
Measure your generator’s length, width, and height. Choose a cover that provides several inches of clearance on each side for airflow, cords, and accessories. If you own a larger unit, select a model with dimensions that accommodate extra space for vents or hoses.
What material and build matter?
Look for heavy-duty fabrics such as 600D or 900D polyester with waterproof coatings and sealed seams. Double stitching and taped seams improve waterproofing and tear resistance. A welded or reinforced hem helps the cover hold its shape in wind.
How well does it fit and secure?
Check for adjustable features such as drawstrings, elastic hems, and buckle straps. A snug fit reduces flapping and rain ingress. Avoid overly loose covers that may catch in wind or blow off in storms.
Weather protection and UV resistance
Durable fabrics with UV-resistant layers help prevent sun damage. Waterproof coatings protect against rain and snow. Consider models that claim all-weather readiness for extended outdoor exposure.
Ease of use and access
Some covers allow quick removal or partial opening for routine maintenance. If you need frequent access to the generator, opt for a cover that you can remove easily without tools.
Additional safety notes
Ensure the generator is completely cool before covering. Keep vents or openings unobstructed to prevent heat buildup. Avoid covers that rest directly on hot components when the unit is running or immediately after shutdown.
FAQ
- Will these covers fit my particular generator model? Most covers are designed for common portable generator sizes. Always verify the product’s dimensions against your unit’s measurements.
- Are these covers waterproof? Yes, most options feature water-resistant coatings and sealed seams to resist rain and snow. Check the material specifications for your preferred model.
- Do covers obstruct ventilation? Quality covers are designed to allow airflow around the unit while minimizing rain ingress. Look for models with breathable or vented designs if you have concerns.
- Can I use a cover while the generator is running? No. Do not cover a running or recently operated generator. Wait until it’s cool before placing a cover.
