Hi @thomas6886, apologies for the delay in response, I had tried to reproduce your issues. In fact the 4C should work fine with USB-C standard, however after investigating across a number of different sites (Amazon, laptopmag, etc) it seems that the Lenovo Miix 320 USB-C port is *data transfer only* and does not support powered devices… so I am quite sure this is the cause of the problem unfortunately.
