Common cord lengths for outlet extenders are 6 feet and 10 feet; many models come with short extension cords in those lengths.
Many extension-style outlet extenders use 16 AWG wire and list amperage ratings around 13 A or 15 A.
Common safety markings shown on outlet extenders include UL Listed and ETL Listed.
Many extenders use flat, space-saving plugs and low-profile designs so they can fit behind furniture or in tight spaces.
Listed ratings include examples such as: 120V, 15A — 1800W resistive and 1000W Tungsten (1/2 HP); and 125V, 15A — 1875W resistive and 1250W Tungsten (1/2 HP).
