My impression of what AirPower was supposed to do was allow me to just throw my shit on the nightstand charging mat and the phone, watch, and earphones just magically charge without fiddling. Not being a hardware engineer, my impression was also that, in order to pull this off, involved big, hot coils and Apple couldn't get rid of the "hot" part.
So now the solution is to buy separate Qi pads for phone and earphone case, and I still need a proprietary charger for the Watch because it doesn't use Qi. Or just say "fuck it", and plug my phone and old AirPods case into the Lightning connectors I already have by the bed, and use the Apple Watch charging stand I already bought.
In summary, I'm one of those that would have spent the $200 on Apple kit if they could have pulled it off because I don't find Qi to be quite the solution I was looking for.
But perhaps that's exactly why it's a stand and not a mat - there are only so many ways to put a phone on it such that it stays there.
I've got a few of these for my old s8 and s10 and they work great. Only downside I can think of is when my battery is low and I need to keep taking the phone off the charger to respond to something, at that point I just cable it in so I can use it and charge at the same time. It's also of course not as fast as cabled fast charging so if I'm very low I'll cable it.
That's not incredibly frequent but does come up every few weeks.
I love them at my desks but I use cables everywhere else as I'm usually grabbing my phone to use it (like in bed).
What Apple was doing that was hard, was to charge multiple devices at a time on a single pad without having set locations.
