QC3.0 QC2.0 Double USB Type-C Mobile Phone Quick Charge Adapter, DC7.1V-32V 3A 30W, Step Down Module
This link product for the car charger class, cannot be used as a mobile power supply motherboard module, is not classed as a step-up voltage default for buck type, we sell the basic buck fast charger, and the input voltage must be greater than the output voltage. So please choose the right power supply.
Various models of mobile phones have differences in fast charging protocol support, so the choice of modules requires some understanding of the protocol, such as PD protocol must be c-port to support, standard usb port cannot work.
Oppo's vooc and Huawei's scp must be high current usb interface, the specific protocol to see the parameters of the introduction of mobile phone super-fast charging is basically a private protocol, rarely licensed to the public, that is, unless the original mobile phone factory out of the Charging head, third-party is not allowed to use, for example, such as Xiaomi mobile phones, if you use the QC protocol, the power will be limited to more than ten or twenty watts. If you want higher power, you have to use the Xiaomi ChargeTurbo protocol, which is not yet licensed to the public. The situation is similar for Huawei and other phone manufacturers. So the power indicated on the module is only the maximum power that the module can provide, not the power that the phone can have when plugged in, as the power varies from device to device.
