2. USB-C - Wikipedia

   en.wikipedia.org/wiki/USB-C

   This means many USB-A–to–USB-C cables will only work in the A to C direction (connecting to a USB-C devices, e.g. for charging) as they do not include the termination resistors needed to work in the C to A direction (from a USB-C host). Adapters or cables from USB-C to a USB-A receptacle usually do work as they include the required ...

   Adapters and cables with a USB-C receptacle are not allowed. [31] Full-featured USB-C 3.1 cables contain a full set of wires and are "electronically marked" : they contain a "eMarker" chip that responds to the USB Power Delivery Discover Identity command, a kind of vendor-defined message (VDM) sent over the configuration data channel (CC ...

4. Lightning (connector) - Wikipedia

   The Lightning to 30-pin adapter supports only a limited subset of the available 30-pin signals: USB data, USB charging, and analog audio output (via the DAC inside of the adapter [27]). Lightning connectors contain an authentication chip that makes it difficult for third-party manufacturers to produce compatible accessories without being ...

   The USB PD specification provides the ability for 5 V devices to draw more than (the USB battery-charging specification limit of) 7.5 W of power from USB "PD-aware" ports when using PD-aware USB cables. The specification also allows USB PD ports to provide even greater power at higher voltages over PD-aware cables – up to 36 W at 12 V and 60 ...

6. Phone connector (audio) - Wikipedia

   en.wikipedia.org/wiki/Phone_connector_(audio)

   The USB Type-C Cable and Connector Specification specifies a mapping from a USB-C jack to a 4-pole TRRS jack, for the use of headsets, and supports both CTIA and OMTP (YD/T 1885–2009) modes. [79] Some devices transparently handle many jack standards, [80] [81] and there are hardware implementations of this available as components. [82]
