Xiaomi YU7 Power Dock Issue
Q: Why does the second Type-C port stop working when connecting a projector to my Xiaomi YU7 roof rail power dock?
A: This is a normal safety feature. When using a Type-C to DC cable to power high-consumption devices (like projectors), the dock automatically disables the second Type-C port to ensure sufficient power supply and prevent exceeding its total output capacity.
