Start by estimating the distance to your power source and the total wattage of devices you’ll run. This range includes cords from 3 to 20 meters and rated at 16A, 250V, up to 3500W. For indoor tasks, a shorter 3–5 meter cord is usually enough, while outdoor projects or distant power needs benefit from 15–20 meter options. Each cord uses 2x1mm copper wire with 32 strands per lead for better conductivity and reliability.

Locking female plug technology prevents accidental unplugging, preserving power during use. This feature, present on several ilock cords, locks the female plug onto the male end to maintain a steady connection. It is especially useful for tools and devices that would be disrupted by unexpected disconnections, such as power tools on a workshop site or equipment in a studio, ensuring continuous operation without constant re-connecting.

Choose IP44-rated cords when you need reliable protection against water splashes and exposure to outdoor environments. In this selection, several cords feature IP44-rated male plugs, which helps guard against moisture intrusion during wet or dusty conditions and makes them safer for use in garages, construction areas, or outdoor settings.

Always match the cord rating to the load and avoid daisy-chaining multiple cords. Inspect cords for signs of wear, keep connections dry, and unplug devices when not in use. Use cords with copper conductors and avoid bending cords sharply or placing them under heavy equipment. Choose models with locking or protective features to minimize accidental disconnections and reduce electrical hazards in workspaces or home setups.

Copper wires with multiple strands provide better conductivity and flexibility, which improves performance under load and makes cords easier to maneuver around a workspace. The 2x1mm copper strands in these ilock cords are designed to handle the 16A/250V rating efficiently while remaining durable for frequent use in homes, workshops, or outdoor areas.
