Samsung 12.3" QHD Touchscreen Chromebook-Plus

Are these good?

Yes! I have two of them at home and I am using one now. Touch screen is mainly useful if you use apps from Google Play store. I like the stylus (hate finger smudges on my screen).

I highly recommend it, if you are a Chromebook fan.

Can you charge it via USB-C?

Yes it charges with usb c. I have one as well.
