What are the differences between Apple Thunderbolt Displays during their production years from 2011 to 2016?

I need to buy a refurbished Thunderbolt Display to use with my (late 2015) MBP. I would like to know what are the differences between Thunderbolt Displays that were produced during 2011-2016?


Only two "models" have been produced:

  1. MC914LL/A (July 2011 - ~July 2012)
  2. MC914LL/B (July 2012 - June 2016)

The only difference between the two models is an additional MagSafe to MagSafe 2 converter which was shipped with the latter model. It allows to charge MagSafe 2-equipped Mac computer. The actual displays are the same.
