Do you have the MagSafe case? Because I have the MagSafe case and it has extra magnets on the case. no idea how strong the bond is, but I saw a video of a guy with the apple MagSafe charger and it held pretty good.I have an Apple Silicone Case and given how weak the magnet seems, I kind of doubt that this HaloLock system will be that secure. With my 11 Pro, I used a Scosche Magic Mount Qi with metal plates, which was generally OK (occasional falling off and connection to vent not very secure). I can't imagine this one being any stronger and would guess weaker. We'll see...
