Chargers from other brands will not match the power specifications of the Redmi 13C 5G. A charger with a lower wattage than the phone requires will charge the phone more slowly. Besides, chargers and cables are designed to provide a specific voltage and current. A mismatch in these specifications will cause the phone to charge slowly or not at all.
The Redmi 13C 5G supports PD2.0, QC2.0 fast charging protocols, and normal DCP charging protocols. It is not compatible with other brands of mobile phone protocols, which will cause slow or non-charging. Please use the standard charger.
Note:
The standard charger supports 10W, and the entire machine supports 18W charging. If you use a charger that supports the PD/QC protocol, its charging speed will be much faster than the standard charger.
