Mag-Safe to USB C Adapter, USB C to Mag-Safe 1 & 2 Charging Connector Adapter Compatible for iPhone 15, M1/M2 MacBook, MacBook Air, MacBook Pro 13'', iPad with USB Type-C

This little device brings mighty power to my MacBook Pro M1 2020 from my 27" Thunderbolt Display. Since the power cable comes directly from the back of the monitor, this adapter eliminates the tangle of extra cables. Since this version of the MBP didn't have MagSafe charging, it has USB-C/TB, this device works wonders! There was a couple of times that it was not working very effectively, but I flipped the MagSafe back and forth, that maybe the prongs weren't as responsive. But after some tinkering, it wound up working great.

Better description/ detail needed for this item. It does not perform the function (conversion/ adaptation) advertised.

I was able to resuscitate an old Mac power supply.

The "Mag-Safe to USB C Adapter 3-in-1" version that is being sold here only provides 30 watts to my 15" 2018 MacBook from my 27" Thunderbolt Display (which provides up to 85 watts), despite the adapter's description claiming to provide 45/60/85 watts. 30 watts isn't enough to prevent the battery from draining while using it on a laptop that normally has an 87 watt charger. I would have been fine with it providing 45 which wouldn't charge the laptop during use but would maintain the battery, or 65 watts which would charge it slowly, but only 30 is unacceptable. Even at 30 watts it gets quite warm, although not hot. I'm returning this.

I inherited a really high quality Apple external monitor that has the functionality to charge your laptop, but the charger was a magsafe1 with a magsafe2 dongle and a computer with a usb-c charging port. I got the version with only the magsafe input and USB c output and it works with both versions of the magsafe that I have and with my MacBook pro. Great solution to keep older technology that is otherwise in perfect condition out of the garbage and be able to keep using it!

It works as a charger from MagSafe1 (Apple Cinema 24 Display) to USB-C on my 2021 Macbook Pro 14, but the USB A/C ports don't work at all (as a USB hub).p.s. Now I read in description(small letters) that additional USB A/C ports work as a charger only, not for Data transfer, and they are not compatible to connect usb-keyboard or mouse.

the product works well enough,i'm happy that it did what i needed to do.but the usb-c and usb-a don't seem to work.

I use to connect my MacBook Pro 14" in clamshell mode to my older Apple Cinema LED Display. This plug converts the magsafe adapter to a USB C connection and maintains all usability in clamshell mode, enabling me to use my laptop as a desktop when at my office.
