When in doubt
Ask the Internet:
Confirming what I saw with my 13 Pro and old USB power banks:
The Apple iPhone 12 & 13 can be charged with the same charger and Lightning cable that came with my iPhone 5s.
No harm done to the newer phones. Just slower charging.
Hey. I will be packing. Overnight works for the 5s. It will work for the 13 Pro.
Since the 13 Pro uses very little battery power during the day, it should charge faster than the 5s.
Money saved!
