Hello,
My Magsafe 1 85W broke down. I have the idea to desolder the cord from the magsafe pcb and attach it to my regulated dc power supply (max 30V & 10A). I would set it up to 16.5V... is that possible at all? I know there is a lot of stuff in those magsafes.
Thanks!
No i want to hook that cord up to this:
Is this a good question?

Given all thats inside the charger I don't think you can replicate it.
If you take the battery out and connect the power supply through the logic board directly then it makes sense. This is how a tech works on systems.
It's not very practical from a use perspective.
Was this answer helpful?
I am working on a repair of the logicboard. I need to power only the board. Just worried about that maybe some signals are not transfered without the magsafe. I think i should buy an original used charger on ebay...
Thats what I would recommend. Just make sure its a real Apple unit not a fake! Counterfeit Macbook charger teardown: convincing outside but dangerous inside & Lacking safety features, cheap MacBook chargers create big sparks

I think its just more useful to replace the MagSafe charger with a real Apple one.
