Abstract
Fast charging methods, fast charging apparatuses, and machine-readable storage media are provided. The fast charging method includes: in response to detecting a successful handshake with a to-be-charged device, monitoring a voltage request from the to-be-charged device, where the voltage request includes at least a QC3.0 (Quick Charge 3.0) voltage request; when the voltage request is the QC3.0 voltage request, determining a voltage combination of a first data line and a second data line according to respective voltage data of the first data line and the second data line in the QC3.0 voltage request; and when the voltage combination of the first data line and the second data line belongs to a first category valid voltage combination, adjusting a voltage transmitted via an output power line of a charger in a preset fine-tuning charging mode, where a voltage adjustment step size of the fine-tuning charging mode is less than a voltage adjustment step size of a QC3.0 charging mode, and the first category valid voltage combination corresponds to an invalid voltage combination in the QC3.0 charging mode.
