The QC3.0 charger has requirements for the charging cable. A mobile phone that supports the QC3.0 fast charging protocol needs to be matched with a QC3.0 charger and a data cable to achieve the corresponding fast charging effect. The maximum output current of the QC3.0 charger is 3A, so just buy a line that can pass 3A current.

The power of the commonly used QC3.0 protocol on the market has no special requirements for the wire. The ordinary Type-c is generally 3A standard. As long as the wire is not inferior and particularly thin, there is basically no problem. Of course, the wire is required to transmit data, which is related to the QC protocol handshake. QC fast charging mainly requires the charger and mobile phone/mobile power supply to support the corresponding version of the QC protocol. If the data cable supports charging and data transmission functions, the corresponding version of QC fast charging can be used.
In the era of QC3.0 charger, the interface was USB-A/USB-C. On the basis of 2.0, the voltage output gear was added, and it was backward compatible with QC2.0, until the era of QC4.0 and QC4.0+ , in addition to being backward compatible with QC3.0 and QC2.0, it also further subdivides the charging voltage gear.
