4 Reasons to Never Use Indoor Extension Cords Outside

Moisture damage is inevitable Even under cover, humidity and condensation seep into indoor cords. Rain splashes and temperature swings accelerate degradation.

Pests attack the insulation Spiders and mice chew on indoor cord insulation, creating shock and fire hazards.

No ground fault protection Indoor cords lack a built-in GFCI. Water in a connection can cause electrocution or fire.

Outdoor cords are cheap insurance For about $15, outdoor-rated cords have thicker insulation, sealed plugs, and better protection. Don’t risk it.
