Specify an EV extension cord by connector ends, AC use, phase, current, length, cable construction, handling conditions and included accessories. Similar product photos can hide variant differences, so require an exact SKU name and complete-set image. Test the cable with the intended EVSE and vehicle before stocking. Southwind can coordinate J1772, GB/T, Type 2 and NACS extension products alongside related adapters; commercial terms remain SKU-specific.
Define both connector ends
Write the EVSE-side and vehicle-side connector in order. Do not rely on “extension cable” alone.
Separate phase, current and length variants
Ask for phase, ratings, length, dimensions, weight and temperature guidance. Never copy one variant’s rating to another.
Show the complete set
Confirm caps, bags, straps and instructions. Use a clean 1:1 image showing the full cable and connector heads.
Validate handling and charging
Check insertion, release, cable routing, storage, start/stop behavior and repeated use with representative equipment.
FAQ
Can the same extension cord be listed for every market?
No. Confirm the configuration and destination.
