I forgot my power supply today, but I have an older powered thunderbolt (2?) display and drives. Can I plug the thunderbolt out from my display into my thunderbolt to USB-C adapter somehow to charge my laptop? The connections I set up now don't seem to be doing anything.
Please hurry ;^) 19% and dropping…. 18%…!

Thunderbolt 1 and 2 do not support power delivery. You won't be able to charge your device from the Thunderbolt cable on your display or drives.
Thunderbolt 3 implemented the USB-C power delivery specification.
