USB Charger heads

A USB charger head (also called a wall charger, power adapter, or charging brick) is the part of a charging setup that plugs into a wall socket and converts electricity into a safe, usable form to charge electronic devices.

It works together with a USB cable to charge phones, tablets, earbuds, and other gadgets.
