I carry a single USB-A to USB-micro cable to connect/charge all of my devices.

USB-C and USB 3 is becoming the new standard, so I will need to carry multiple cables or a single cable and an adapter for one of the terminators.

What are the explicit differences regarding USB-C's data transfer speed and charging speed for new devices between the following configurations?

  1. A cable from USB-A male to USB-C male and a USB-C female to USB-micro male adapter
  2. A cable from USB-A male to USB-micro male and a USB-micro female to USB-C male adapter
  3. 2 cables and no adapter

    If you are converting from USB 3 Type C to anything else then your limited by the other end – Ramhound Jan 14 '16 at 12:19

With regard to transfer speeds, USB-C has no effect. USB-C is distinct and separate from USB 3.1/3/2/1.1 and your transfer speeds are determined solely by the capabilities of the devices communicating at either end.

  1. A cable from USB-A male to USB-C male and a USB-C female to USB-micro male adapter

This configuration is not permitted by the USB specifications.

  1. A cable from USB-A male to USB-micro male and a USB-micro female to USB-C male adapter

This configuration will charge and transfer data at whatever the maximum capabilities are of the least capable device, exactly the same as any other kind of USB connection.

  1. 2 cables and no adapter

This configuration will charge and transfer data at whatever the maximum capabilities are of the least capable device, exactly the same as any other kind of USB connection.

    So for 2. (A cable with a micro-C adapter), does the "least capable device" include the cable? The cable I'm currently using is currently rated USB 2.0. So if I wanted to make the most of data/charge I'd want to get a better cable. – StuperUser Jan 14 '16 at 13:32

    @StuperUser: USB 3.0 has additional wires, and the power wires are sized to handle more current. You won't get USB 3.0 functionality if any part of the cable is USB 2.0 (although it will make a USB 2.0 connection). BTW, there are length limits, so a simple adapter will work, but probably not another cable that plugs into the end of the first one. When all is said and done, you're probably better off with dedicated cables with the right connectors. – fixer1234 Jan 14 '16 at 22:05
  • You will get USB 2 data speeds and normal charging speeds. – qasdfdsaq Jan 15 '16 at 11:28
