Hi,
May be a silly question but thought I might get some clarity from forum members.
I alternate charging my iPhone between a wireless charger and charging from iMac 2019 (21.5").
Charging from the Mac is always faster.
Wondering if charging from iMac is safe for battery longevity.. How does it compare to a 20W charger for example?
