I have the same charger. It has worked really well. Will keep it for the Max. Not like I am in a hurry overnight, which is when I use the two wireless charging units.Not sure if I can believe but my always wireless charged X is showing 100% battery health after a year.
Using the Morphie wireless charger that was purchased from Apple.
Will keep using this charger on my MAX!
