I have an older 27" Thunderbolt Display which has a video out and a Magsafe cables come standard in a bundle. I am curious if the Magsafe 3 port in the new MacBook Air M2 is compatible with the Magsafe power plug in my older Thunderbolt display?

That monitor's MagSafe 1 plug is not compatible with MagSafe 2 and MagSafe 3 ports.
Apple sells a MagSafe 1 to MagSafe 2 converter. I don't see any converters to go from MagSafe 1 or MagSafe 2 to MagSafe 3.

Mr. Rayfield suggested that it might be possible to convert to USB-C ( Power Delivery ) with third-party products. One link is now broken.

Can I charge a MacBook Air M2 with the Magsafe charging cable from my 27" Thunderbolt display?
