I was very satisfied when it first arrived yesterday and it seemed to work fine until this morning when I noticed it stopped charging about midnight. I've tried both ports, blew both out with compressed air, tried different wall outlets, different cables, nothing. The same wall plug/cable WILL charge my older Macbook Pro and my Nintendo Switch, so that's working. The top port will read my external drive, the lower USB-C port does absolutely nothing. Ran Diagnostics and it reports that I may have a charging port issue or a touchbar issue, but touchbar is fine once it is fully started. Does not seem to be a way to contact the seller outside of reviews to get any help, so I guess I'll have to clear it while I still have battery left and send it back.
