I use this charger for my iPhone 13 Pro and for my Sony WF-1000XM4 earbuds. I love being able to have this setup on my desk while I work from home, knowing that my devices are always topped up for when I go out.
The phone stand has two postions it can be set in, so it's quite easy to still use the phone whilst it's charging. The connection is good, and I've never had to move things around to find the sweet-spot.
Build quality seems solid, and being able to fold the stand flat means I can take it with me anywhere in my bag.
I haven't tested the Apple Watch charging as I haven't got an Apple Watch (yet), but I've opened the base of the charger to see how the cable would be routed and it seems pretty straightforward.
