MagSafe 2 to MagSafe 3 converter

In my opinion:

The new MagSafe-3 uses a more sophisticated power negotiation, probably more similar to USB Power Delivery than the original very simple 'MagSafe power negotiation' which in some ways served a prototype for USB Power Delivery Protocol.

So they made it a different shape on purpose. It has no hope of working with the older MagSafe and MagSafe-2 power adapters, which were cross-compatible with each other and an adapter was available.

You could connect your old MagSafe to one of the MacBook Pro's USB-C/Thunderbolt ports with one of these adapters.

PC Magazine has an article on this: https://www.pcmag.com/news/sadly-new-macbook-pros-wont-work-with-older-magsafe-chargers

The short version of the answer is "no, you'll need to purchase a new power adaptor"

From technical perspective, Magsafe 3 is indeed USB PD 3.1.

I'm not sure if there's any special specs out of PD 3.1 standard in Magsafe3 but since there're some adaptor from USB PD to Magsafe 2, I assume it's possible. But I'm afraid the demand of it is quite low so not sure if this sort of stuff arrives soon.

No one knows the answer to that.

Will there be a MagSafe 2 to MagSafe 3 adapter like for the previous generation of MagSafe? I have a 67w MagSafe 2 charger that I’d like to use as a travel charger for my 14 inch M1 pro that’s arriving soon.

Use the charger that ships with your new Mac.

I would love to have such an adaptor too!

i own several 85W MagSafe 2 chargers from my 2014 15“ retina, and would love to still use them! Probably charging speed wouldn’t be as good, but even just as a docking station for my new 16“, so I can plug it in at different workstations without everytime having to take out the charger and pluging it into a socket!

Wouldn’t it be possible to include a small chip into the adaptor to convert the MagSafe 2 protocol to a magsafe 3 protocol?

with today’s possibilities on small chips, I can’t imagine this would be that hard, I mean look at what airtags can do and how small their chipset is😅

Done.🤘
