ChromeOS and Android have a lot in common.
Going to GOS full time is my plan if my old T470 Thinkpad dies. It does pass-through charging when connected to my Anker hub. My hub has 2 USB 3, monitor, SD, microSD, and ethernet ports.
Keep battery optimization on so the battery stays at 80% and lower.
All I need is a wall monitor mount, a monitor and cable (if it doesn't come with said cable). I used to use a Samsung tablet as my main "computer" so I still have the Logitech BT keyboard and trackball.
