A leak has confirmed that the Redmi K30 and Redmi K30 Pro will soon be joined by a device called the Redmi K30 Ultra. Possibly the real name for the rumoured Redmi K40, the device has been spotted with a 64 MP primary camera and a pop-up selfie camera. Xiaomi has just certified a 120 W with the 3C too.

There's no way Xiaomi will put 120W brick adapter for a phone. Hell,.even until now, there's no laptop that could pump that much of watt to recharge its battery.
To supply power might be possible, but no recharge.
