@fossdd I was annoyed that charging stand they give you is only compatible with region where you bought it (wish I knew it was just wireless charging when I was in Japan), but it was somehow compatible with two different charging stands (some supermarket special and philips at friend's places).
That got me thinking it had to be some sort of standard, so I placed it on top of PinePower next to friend's couch... and it just worked lol. It's really handy to know
