My tablet with lineageOS works with very few select usb-ethernet adapters (ASIX AX88179 chipset)

But since it doesn't support charging while in OTG host mode, it cannot stay plugged into the adapter for long (old battery)

Some newer devices like Samsung support ACA OTG (Accessory charging adaptor)) with charging while powering the adapter

Another fun reason for wireless charging -- sometimes it's just easier to sneak power into the device by a side-channel than to try to find the right chain of adapters.

On older devices wireless charging usually doesn't provide enough power to sustain the battery level while working though. Because very few of them have Qi quick charge.

What’s old is new again; Windows Phone devices did USB charging + ethernet (+ display) a decade ago.

I was really shocked when they stopped making android phones with USB micro hdmi support, which basically allowed playing games on TV

That's because a lot of new phones (and tablets) support video via USB-C just like laptops.

Pedantic nitpick to say: USB is a serial protocol, but video is not serial? It's a Displayport or Thunderbolt connection, using a USB-C-shaped connector and cable

My HDMI Philips monitor supported MHL. And DVI-D, incidentally.

However, I was never able to use MHL display. None of my devices seemed to support it. Android Kitkat/Lollipop, Samsung Galaxy Tab.

I’ve no idea what sort of cable would’ve been needed. There was no USB connector on the monitor.

I had a micro-usb to MHL adapter added to my nexus tablet (forgot already which version)
