Nope, finally found it in the USB-C spec, section 4.6.2, covering cables: "USB Power Delivery in Standard Power Range (SPR) operation is intended to work over un- modified USB Type-C to USB Type-C cables, therefore any USB Type-C cable assembly that incorporates electrical components or electronics shall ensure that it tolerate, or be protected from, a VBUS voltage of 21 V." This comes after a table that would seem to indicate USB-C as a whole supports a minimum of 7.5W, but then this cable-specific section expands that. However, it notes that it must tolerate or be protected from, which in this context I gather means "must pass power through." |
