Buying Guide

Match cover size to your generator

Measure height, width and depth of your generator and choose a cover dimension that allows for ventilation and access while providing a snug fit to prevent flapping

Prioritize weatherproof materials

Look for heavy-duty, weather-resistant fabrics and sealed seams to protect against rain, snow, and UV degradation for long-term outdoor use

Check ventilation and airflow

Covers or tents with vents or breathable panels help prevent condensation and overheating while the unit is stored or lightly used outdoors

Consider portability and storage

If you move the generator frequently, choose a lightweight, foldable cover or a carrying case that simplifies transport and stows compactly

Assess attachment and stability features

Straps, drawcords or secure fasteners reduce wind lift; heavier or reinforced designs increase stability in exposed locations
