What is the roof rail power expansion dock on the Xiaomi YU7 used for? What third-party products can be connected to it?
Official answer
The Xiaomi EV roof rail power expansion dock is a power extension product designed to be used with the Xiaomi EV roof rail. Installed together on the rear ceiling of the Xiaomi YU7, it can connect to devices such as 4K gimbal cameras and projectors (only when parked). It draws power directly from the vehicle via a pin interface, providing power to third-party devices at any time. The side of the power expansion dock features dual Type-C power interfaces, with a maximum single-port output power of up to 100W, allowing you the freedom to power two devices simultaneously even when you are out and about.
