USB charger ?
Yes, since most modern chargers and cables have internal chips to communicate capabilities with for things like fast-charging. It is not difficult to have the chip identify itself as something else, and execute a payload.
A common attack method is to have it show up as a keyboard, and execute a series of key-sequences when connected to a computer (like opening and executing things through a command prompt).
It is also why you should try and avoid plugging random USB cables/chargers into your phone/computer when out and about, since you don't exactly know if the other end is what it appears to be.
I don't know enough about the charger thing to comment on how viable that might be for an attack vector.
But you're definitely right about plugging your mobile device into random ports. Either set your phone to by default only charge and not communicate, use a charge-only cable, or only use your own power bank/charger when away from home and you don't fully trust where you are...
