5 Key Differences Between Power Strips and Extension Cords

Power strips add outlets; extension cords add reach A power strip turns one wall outlet into several. An extension cord brings power to a distant spot, usually with just one or two outlets.

Power strips often include surge protection; extension cords do not Most power strips protect electronics from voltage spikes. Extension cords are just wire—no surge protection at all.

Never plug a power strip into an extension cord This overloads circuits and risks fire. Plug the power strip directly into the wall, then use an extension cord only for the single device that needs extra reach.

Cheap extension cords with thin wire overheat under heavy loads Use a cord rated for the device’s power draw. Thin cords are fine for lights, not for space heaters or power tools.

Never hide either under rugs or furniture Both generate heat. Trapping them blocks airflow and increases fire risk. Keep them visible and uncovered.
