Hi there, thanks for reaching out.
MagEZ Case for iPhone 11 Pro Max can work with MagEZ Mount Qi, but it can’t work with MagEZ Car Mount Pro.
The Pro version is designed for iPhone 12 & 13 series.
You can choose the MagEZ Mount Qi here:https://global.ipitaka.com/collections/magez-mount-qi
I hope the above information is helpful. Please feel free to contact us if you still have questions. Thanks.
