Source power-rating qualification

Source qualification: the Power Delivery row states 240W, while generic connector descriptors contain 100 W labels. Do not derive or promise end-device charging from connector taxonomy; confirm the exact rated cable/charger/device combination before ordering.

Documented selection limits

Match the exact connector at each end, cable length, interface generation and host/device requirements. Published data rates, power ratings and display modes are maximum conditional limits, not guaranteed application results. A physically matching connector alone does not establish protocol, charging, video or device compatibility. USB-C shape does not guarantee USB4, Thunderbolt, DisplayPort Alt Mode or USB Power Delivery. Charging, data and display capability differ between cables. USB 2.0 charging/sync cables must not be advertised as high-speed USB4/video cables. Check active/passive type and the exact supported host mode. Source qualification: the Power Delivery row states 240W, while generic connector descriptors contain 100 W labels. Do not derive or promise end-device charging from connector taxonomy; confirm the exact rated cable/charger/device combination before ordering.
