What happens if you plug a USB into a charging port?

Absolutely nothing bad would happen if any standard USB device were plugged into a USB charger. At worst any “power” LEDs that light up when plugged into a computer would still light up, but nothing more. A USB charger puts out 5V unless the device negotiates a higher voltage.

Can USB flash drive be attached to any USB port?

Does a flash drive need to be charged?
