Do the connected devices get power supply from Thunderbolt?

All the devices connected to the Thunderbolt port get power supply. However the level of the power supply depends upon how far are the connected devices from the primary device directly connected to the AC power supply in the device sequence.

If the devices are connected to a primary device running on battery then the charging process will be slow and the primary device may get drained out of power soon. Hence it is advised to connect all the devices directly to the power supply if possible or to a primary device currently plugged in.



What are the various ways to use Thunderbolt optimally?

  1. The various ways to get optimum performance from thunderbolt technology are as follows:
  2. Ensure that your Mac is running on Mac OS X v10.6.8 or any other later version.
  3. Install all the latest software and firmware editions as suggested on the ‘Software Updates’ section of your Apple Menu.

Will all Thunderbolt devices stay connected when my Mac goes into hibernation?
