Can I use the USB-C Apple adapter, to charge my MacBook 12', with USB-A port? I have:


MacBook 12"
USB-C AV Multiport Adapter
USB-A to USB-C cable
USB-C Macbook 12' charger


Basically I want to keep the USB-C port on the adapter free. 

So, instead of using a USB-C cable to plug the charger to the adapter, I want to use the USB-A port on the adapter.

Will this work?
No, this will not work.  You cannot charge through the USB-A port.  

The USB-A port is a 3.0 port which will supply 5V of power, but it will not be able to negotiate to receive power per the USB 3.1 spec.

Per the Multiport AV Adapter specifications:


  Use the standard USB port to connect devices such as your flash drive
  or camera, or a USB cable for syncing and charging your iPhone, iPad
  or iPod. You can also connect a charging cable to the USB-C port to
  charge your Mac.
