Here is my current setup. I like seeing what everyone else uses, so figured I'd share.

Current travel is 85% USB-C. I almost exclusively travel with ipad pro unless I need to present and no jr. staff is accompanying me or i have a lot of editing to do, in which case lenovo laptop comes as well (both USB-c). Two iPhones (usbc). Airpods (usbc). Occasionally airpods max (lightning).
Of importance is ability to charge several devices overnight, since i frequently do several 1 night hotel stays per week (ipad/computer, 2 phones, headphones)

-Charger (either or). Normally - mag safe (5000mah) to keep things lighter or 10,000mah w/ 30w if i think i'll need more
-Anker 100w charger
-Anker 30w charger (i like this one bc its light and works much better in looser airline/club outlets)
-USB-c wired headphones
-air fly
-C-A and A-C adapters
-USB driver
-screen cleaner
-sim tool (forgot this was in there...)
-two different generic lighting/micro/usb-c cords. Handy for charigng everything at once but rarely used
-OEM apple and OEM lenovo usb-c cables
