Hi, This used to be dangerous— when chargers were not smart. Today’s USB based chargers should negotiate between the device and the charger and provide the max safe charging that the charger provides. I have on occasion used my MacBooks M3 charger with my iPhone. Generally, I won’t but if the phone is below 20% and I need to go out in the next 30 minutes having the quick charging increases my confidence that I can use my phone in a navigation emergency. 19 watt USB-C charger does not provide a straight 19 Watts, but might have options for 3, 7 , 12, 15 and 19 watts. )Note, I made those numbers up).
If the device says it wants 16 watts to charge then with the above charger it would get the 15 watts choice. This can be seen in the System Information App while the M1 is charging as is discussed in this article: What’s the max PD charging for the new M1 MacBook Air and Pro? : r/macbook <https://www.reddit.com/r/macbook/comments/k21lyc/whats_the_max_pd_charging_for_the_new_m1_macbook/%23:~:text=From%20my%20observation%20it%20seems,higher%20wattage%20chargers%20are%20useless> -- The following information is important for all members of the Mac Visionaries list.
