Do you think it is possible to connect the Thunderbolt Display’s Mag-safe power line to this adapter within the display internally?

So I can use my Thunderbolt Display with my newer Type-C ported Macbooks with just one single cable just like LG’s Ultrafine Monitor using external display while charging my mac laptops?

Or is it a bad idea modifying it like that? (catch fire or something?)

Thanks.

Since the Thunderbolt 3 spec is not publicly available, we can’t know about the negotiated voltage and power capability on the type-c side of this adapter. Even if the power input meets the requirement of Thunderbolt Display, it’s quite hard to apply any hardware modification, as you can see the complexity of the circuit and density of components on board.

Thanks for your kind answer Yuxiang.

I was hoping as if I could (1)buy thunderbolt type-c cable from amazon, (2)cut both cables open(adapter’s cable & amazon’s cable), (3)grab mag-safe wires from the display and solder them into the amazon’s extra wires that must be lacking in the above adapter(assuming because it doesn’t support charging), (4)connect the amazon’s cable to my macbook, then BOOM, it magically works.

Thanks for saving my macbook and my TBD.

It might be possible through the use of thunderbolt pass through dongle but those are expensive and would require even more hardware and bulky solution. I’d recommend just using a car charger with usb pd 65w and soldering a MagSafe socket to it. Two cable solution but now the display can charge your MacBook usb c
