I'm not sure that's true.

I believe modern wireless chargers are around 75% to 85% efficient.

That sounds bad at first, but I believe most ac-dc charging bricks are in the 80% to 90% efficiency range, so it's actually not much worse at all.

And if it really is magsafe, the "secret sauce" there is the magnets will align things almost perfectly every time avoiding unaligned charging coils.

There's still a charging brick powering the wireless charger so isn't the 75-85% stacked on top of the 80-90%? That gives you 56-77% efficiency.
ah good point, I'm not sure what I was thinking!
But will users know or care?
But aren't you going AC->DC->wireless? So it would stack
