I have magnetic connectors for USB-C in both varieties. The circular one I normally use just has two pins and is great because I put my phone down near the cable and it usually leaps across and connects. The multipin flat connector supports PD and data, I'm not sure exactly what its limits are but it does what I want.

Both were cheap ebay purchases made because I'm willing to plug a $10 cable into a $600 phone despite the early USB-C cables occasionally frying devices.
