Is there a big difference between Xiaomi 8qc4.0+ charger and the original one?
When Xiaomi 8 mobile phone is charged normally, the charging time of qc4.0+ charger is the same as the original one.
Although Xiaomi 8 supports QC4.0+, it does not fully adapt to the charging head of QC4.0, that is to say, Xiaomi 8 can be charged with high current, but the voltage is unstable, but it cannot reach the high current and low voltage mode. In the case that Xiaomi 8 has not fully adapted to QC4.0 charging head, the charging speed of Xiaomi 8 is still similar to that of previous QC3.0.
Extended data
The DC output parameters of Xiaomi 8 original charger are: 5V/3A, 9V/2A, 12V/ 1.5A (supporting QC3.0). The DC output parameters of QC4.0 are: 5V/3A, 9V/2A, 12V/ 1.5A, 3.3v-5.9v/3a, 3.3V- 1 1V/2A. Xiaomi 8 QC4.0+ charger 5 original DC parameters are different.
Although the output of qc4.0 can reach up to 35w, Xiaomi 8 mobile phone only accepts 18w. There is no difference between the actual measured value and the original value. However, if Xiaomi 8 uses Qualcomm's qc4.0 protocol, it will better protect the electronic components of the mobile phone and increase the charging power because of the reduction of voltage, which can save at least 30% time compared with QC3.0.
QC4.0 charger increases the power to 28W and adds USB PD support. Cancel the voltage of 12V, the maximum output of 5V is 5.6A, the maximum output of 9V is 3A, and the voltage range continues to be subdivided to 20mV. In fact, Xiaomi 8QC4+ and Xiaomi 8' s original QC3.0 charging head are similar.
