flat outlet extension

Flat surge‑protector extension cords show a range of joule ratings depending on the model. Examples in the results include about 250 J, 1,080 J, and up to 2,480 J for higher‑rated units.

Many flat extension cords list 16 AWG wire and a maximum amperage of 13 amps in their electrical specifications.

Space‑saving designs include flat or low‑profile plugs, angled or rotating plug heads, and low‑profile outlet bodies—features that allow insertion behind furniture and in tight placements without blocking adjacent outlets.

Common safety marks shown for these cords include UL listings and ETL listings, depending on the specific model.

Many flat extension cords feature adapter‑spaced or generously spaced outlets and layout designs that prevent large adapters from blocking adjacent outlets, allowing bulkier plugs to fit comfortably.
