I stopped trusting USB-C cable labels and started testing them with a $15 meter instead
USB-C was supposed to be the one connector for everything, but its versatility means cables look identical while hiding wildly different capabilities. The author, tired of guessing which cable could fast-charge his MacBook Pro, bought a $15 USB tester. By plugging it between cable and device, he could read voltage, amperage, and wattage to identify each cable's real charging speed. He then labeled every cable in his drawer, turning guesswork into certainty.
But I shouldn't have had to do any of this. It's time cables came with a label of their own, or some sort of color coding.

Is there a cheap, reliable tester that someone can recommend that will test multiple USB cable types (A, micro & C)?
