Recently got a USB-C inline meter that shows voltage, current, and power. Checking a couple old Anker power banks, with USB-A (one also has C) they provide 5-6 watts. For last year’s GAP/C&O trip I picked up a 45watt power bank that supports PD (https://www.walmart.com/ip/JUOVI-Portable-Power-Bank-20000-mAh-Battery-Pack-45-W-Fast-Charge-Compatible-Switch-MacBook-Tablet-Dell-HP-Notebook-Samsung-iPhone-Steam-Deck/10773165668). My USB-C iPhone draws 15 volts and almost 1.5 amps (more if phone has low charge and camera active), for 22+ watts. Surprisingly my 2021 Macbook doesn't charge the phone as fast as this power bank (~14watts). Also with a USB-C to lightning this power bank charges an old iPhone 11 at 10w, normally it does 6-7w with USB-A.Moral of the story: USB-C and PD capable power bank if you can swing it! Also, for traveling, a 45w or 65w AC charger will top up the power bank quickly as well as charge another device.Paper on USB power delivery:https://www.ti.com/lit/wp/slyy109b/slyy109b.pdf#USBC #BikePacking
