Some listings show third‑party safety marks such as UL Listed or ETL Listed. A few entries explicitly state that no certification is provided in the product details.

Listings mention SJTW jackets, vinyl or PVC jackets, and braided fabric (woven) power cords for a more decorative or flexible cable option.

Common lengths shown in the listings include 6 ft, 10 ft, 50 ft, and 100 ft.

The listings show wire gauges of 10 AWG, 12 AWG, 14 AWG, and 16 AWG, with amperage ratings commonly listed as 10 A, 13 A, or 15 A.

Results include single‑outlet and three‑outlet cords. Many listings describe three‑prong plugs, and at least one mentions compatibility with two‑prong devices.

Some cords have a lighted end to indicate power and brightly colored jackets for visibility. Others use low‑profile or flat plugs for tight spaces, and one listing notes tamper‑resistant outlets.

Listings describe SJTW or 'waterproof' jackets and durable vinyl jackets that resist tearing, abrasion, moisture, oil/grease, and sunlight. Some entries also provide an operating temperature range (for example, −40°F to 130°F).

Listings mention indoor lamps and small appliances, holiday lights, power tools (drills, saws), and some also list garden and lawn tools (including lawn mowers).
