This is the exact one I bought:

I got it half expecting it to be a piece of crap, but I've been really happy with it so far. Mind you, the power source still needs to have a certain output to charge your Macbook, but it's allowed me to use the same USB-C charger that comes with newer Macbooks with my 2015 Macbook.

EDIT: I hope that was what you were picturing. I suppose someone reading my comment could have interpreted it as a magsafe-to-usb-c connector.

I was talking about the things that add magsafe charging while still allowing data transfer for current usbc macs. I'm simultaneously sad and happy to not be proved wrong. :(

This is what I use with my Intel 16” MBP and M1 Air.

I tried several of those and the magnets were all so bad that they couldn't even support the weight of the cable itself and would lead to fraction-of-a-second disconnects, which in one case led the mac to disable charging on the port (temporarily. the apple store fixed it but I don't know how).

At this point I don't think the reward is worth the risk. But I am glad to hear that at least some of them aren't terrible.

I use it to connect to the dock on my desk, so the cable weight wasn’t an issue, but I can see how the weight of the cable pulling down would disconnect the magnetic connector.
