As someone who travels a lot for a living, I have two chargers in my travel pack. Always. When I come home it stays there until I’m out and about again.
Other things that always stay in my carry-on kit:
Phone stand
Two pairs of socks
A t-shirt
A network cable
A bunch of USB sticks
20000mAh battery bank
plastic fork (for eating cup noodles. I used to carry a metal one, but airport security somewhere didn’t like it)
