November 1, 2026. Before buying a USB-C cable this month, separate two questions: how much power it is rated to carry, and what data capability it supports.
The USB-IF’s compliance guidance requires USB-C-to-USB-C cables entering its program to carry a 60W or 240W power marking. It separately requires data-rate markings for the relevant cable categories, with an exception for High-Speed USB (USB 2.0) cables. These are certification-program requirements, not a claim that every cable sold has those marks.
Match the job, not just the plug
Identify whether you need charging, data transfer, a display connection or a combination. Check the documentation for the connected devices and the exact cable model. Do not infer every capability from the USB-C connector alone.
USB-IF also notes that a certified cable does not add capabilities to the devices it connects. Buying a higher-rated cable is therefore not, by itself, a way to upgrade a computer’s port.
Keep a record of the exact model
Save the specification or label a cable for its tested role in your own setup. That can prevent a known-good display or storage cable from becoming an anonymous item in a drawer.
If a listing supplies only a wattage or a vague claim of speed, look for the missing specification before purchasing. This is a selection checklist, not an independent certification or performance test of any product.
