OK, most of your mag chargers on the market transfer data from the computer to your phone, but most of them don't read the static SD card back to the phone or transfer it Videos on a projector or monitor. It will and you can charge your phone at the same time with the right setting. In this case, as you can see in the photos here, the phone is connected to the hub, the charger, the SD card and the projector are connected to the hub. As you can see, the phone loads and reads the external SD card and sends it to the projector at the same time. And I don't wear out the USB-C port on my phone, the magnet always stays. I bought several to have one in the car, at work and by the bed.
