Outdoor Generator Covers

Measure your generator's height, width, and depth and compare to cover dimensions; allow a few inches of extra room for airflow and any attached cords or hoses. Check whether the cover lists compatible wattage or model ranges and consider covers with adjustable straps or drawcords for a snug fit

Look for waterproof or water-resistant fabrics such as heavy-duty polyester with a polyurethane coating, taped seams, and a water-repellent top; UV-resistant treatment helps prevent sun damage. Features like reinforced seams, vented panels to reduce condensation, and secure fasteners (buckles, straps, or drawcords) improve durability and weather performance

Brush off loose dirt, rinse with a hose, and clean with mild soap and water; avoid harsh detergents and machine washing unless the manufacturer permits it. Allow the cover to air dry completely before storing it folded in a dry place, and repair small tears or seam damage promptly to prevent worsening

Look for locking grommets or padlock-compatible eyelets if theft prevention is a concern, and ensure vents or clearances for exhaust and heat dissipation to prevent overheating. Never cover a generator while it is running; choose a cover designed to fit only when the unit is off and cool

Prices vary by size and material; budget options often start under $50, mid-range covers are commonly around the average price for the category (approximately $80), and heavy-duty or large covers can cost more. Consider the trade-off between upfront cost and features like UV protection, heavier fabric, and reinforced construction

Universal covers offer flexibility and can fit multiple units but may not provide an exact fit, while model-specific or size-specific covers can offer a tighter fit and tailored features for particular shapes. Choose based on whether you prioritize precise fit and protection or broader compatibility across different generators
