This is why I've never really found AirPower to be that compelling of a product, even though I buy lots of Apple stuff. Yeah, it's a pretty nifty technological thing (apparently too nifty!) but … why should I care?
I nearly never want my Watch and my iPhone on a charger at the same time because I pretty much always have at least one of them with me. And I charge my AirPods case so rarely (I plug it in for a few minutes once a week or so when I think to), it's not really compelling to me that it charges it separately.
Anyway, I'm sure other people differ...
