I have a collection of Apple chargers I used with a variety of Mac laptops over the years. I have inspected them as best as I can and am unable to determine how many watts each of them outputs. I want to reuse what I can without harming the equipment in any way.
Can anyone tell me where to find the secret decoder ring for charging adapters? :-) Thank you!

First … any Apple Power Adaptor can be safely used w/ any Apple device as long as the cord’s plugs physically “marry up.”
A newer device might not charge quickly w/ an older adaptor … but it won’t damage anything.
(I still use an ancient 5W Apple “Icecube” for nighttime charging of my late-model iPhone)
The wattage is in the teeny-tiny grey type on any adaptor.
(Most normal humans require a magnifier)
Watts = DC Volts * Amps

Thank you for your help! I also overlooked the side of the charger where the AC prongs are located: this side clearly indicates which charger it is. In this case, 61W. Doh!
Thank you again!
You’re certainly welcome. 👋
