Review on TITACUTE USB Type C Anti Dust Plug 2 Pack: Keep Your Ports Clean with Stylish Dust Covers for Samsung Galaxy S20, OnePlus 8, and More! by Bobby Valadez

Something a lot of people don't understand. If you carry your smartphone with you and do not protect the ports, especially the USB port, particles can get into the port. The most common things that end up in a USB port are borrowed dirt/dust that can affect the connection when charging the phone. These USB ports/plugs are a trick that can save you a very expensive repair bill unless you can fix it yourself. I use the USB port when I leave the house. A dustproof plug is a great idea, it can save your phone.
