Fun fact. Any USB-C cable that needs to handle higher wattage than 5V@3A has circuitry that talks on the CC line to let the source know it’s not going to melt.

  The threshold is higher than that. Passive USB-C cables can do up to 20V @ 3A (60W). Electronically marked cables are only required for higher power profiles.

    To be pedantic, the eMarker is required in a USB 2 cable conducting over 3A, and in any USB 3+ cable.
