It’s already my 2nd unit, same problem, Now at least I know how to get around it. I just use my regular charger to bring it up to 80% then plug the hub. I’m not surprised there that cheap PSU from china isn’t providing clean power when used at it’s capacity.
So when laptop is charging and being used at the same time and maybe combined with PSU overheating, it start to give out bad current that my laptop reject.
I’m happy that my laptop protect me from that, other laptop mobo or battery might just break prematurely.
If you want to send me another PSU to test out, I wouln’t mind but I don’t want to be without a unit to get a replacement.
