I see some 24 pin "magnetic usb-c" adapters with 100W PD and TB3 compatibility on Amazon/Aliexpress. They need an existing cable so likely they just pass-thru cable capability discovery to an existing chip. Apart of some wear issues, reviews are rather positive. Anyone tried such?

None of them work unfortunately. They can pass USB 3 through, but you can't run anything beyond that. No video, no thunderbolt. I've tried several variants of them, they're all the exact same product and they don't work.

I got one recently. Haven't had it for long enough to see wear issues, but I'm surprised how well it's worked. Biggest annoyance is that it's sensitive to being jostled. When it was just power, that didn't matter so much, but when it's connected to my docking station, it's the same as yanking the cable. It's staying, for now, but I have to be careful moving things around on my desk. Edit to address sibling concern: It's running a TB3 screen, so seems to be working for that...

  Would really appreciate a link. Have been looking at magnetic USB C connectors but some look shady/bad.

    Wanted to wait until this dropped off the front page out of respect for chx's concerns. In that vein, let me say that I have neither the skills nor the equipment to evaluate any of chx's technical concerns. The best I can say is that it seems to do what I want (pass power and TB3 with a magnetic coupling), and there haven't been any symptoms of problems that I've been able to see. Yet. I'm now a little worried, though :| The 24-pin one here is what I'm using: https://www.amazon.com/dp/B0896QK2J5 https://www.amazon.com/dp/B0896QK2J5

      I use the same one and it works for me with the Caldigit thunderbolt 3 dock.

Yes, Amazon reviews completely override the laws of physics. It is known.
