Those ghost touches  are Samsung/Microsoft to blame thing. I have same issue on Surface pro 1 gen. Just turn off touch driver when device is plugged to charger. I can recommend logitech k380.

I tried linux on cube i get very aggresive throttling. If i try for example sculpt on this device it throttles to 800mhz and is almost not usable. Temps are around 60’C. In windows it gets very hot like 90’C but never throttles.

Im not sure if this baseus will work. I have three baseus pd chargers, 30W car charger, 30W and 60W wall chargers and all of them do not want charge Cube mix plus. They only work if i plug them throught dodocool 7in1 hub. I wonder if this powerbank has same issue but i would not risk ordering another baseus.

regards.

18W from power delivery is too small. You will need at last 24W power output. Preferable 30W.

“I measured 12+V between the terminals of the barrel jack” that 12v is not important. What kind of usb c charger did you tried? It has to be charger with power delivery 24W minimum.

Hi, i think that the problem is PD 3.0. It is not fully compatibile with PD 1.0 that cube mix plus supports. Today ive finally put ma hands on car charger
