No, the Redmi Note 14 Pro+ 5G doesn't support reverse wireless charging.
For your reference, here is more information about reverse wireless charging:
1. Reverse wireless charging is a technology that allows a phone to charge other devices wirelessly. Unlike regular wireless charging, where the device is charged by a wireless charging pad, reverse wireless charging turns your phone into a charging source to power other devices, such as another phone, wireless earphones or a smartwatch;
2. Reverse wireless charging works based on electromagnetic induction, which is the transfer of energy from the phone's charging coil to the receiving device's coil. The phone itself emits energy via its charging coil, which is then absorbed by the coil in the other device, charging it without a physical cable connection.
