Home >Common Problem >Which protocol does vivo fast charging belong to?
vivo fast charging mainly has two protocols: 1. "QC 2.0" fast charging protocol. "QC2.0" is the "Quick Charge 2.0" technology. It is the 2.0 version of fast charging technology released by Qualcomm. Outputs four voltage groups of 5V, 9V, 12V, and 20V; 2. PD fast charging protocol is a fast charging specification formulated by the "USB-IF" organization. It is one of the current mainstream fast charging protocols and can make the current default maximum The "type-c" interface with power "5V/2A" is increased to 100W.
The operating environment of this tutorial: OriginOS 2.0 system, VIVO X80 mobile phone.
The charging protocol that the device is compatible with can be judged based on the maximum supported charging power:
Note: vivo ultra-fast flash charging, vivo flash charging, Dual-engine flash charging is vivo’s own fast charging protocol
1, 44W and above: supports vivo ultra-fast flash charging protocol;
2, 33W/22.5W: supports vivo flash charging Protocol;
3. 10W: normal charging, not fast charging;
4. Models with a maximum charging power of 18W: support dual-engine flash charging protocol and QC 2.0 fast charging protocol;
5, X80, X80 Pro, X Fold, 2.0 fast charging protocol and PD fast charging protocol.
QC 2.0 Quick Charge Protocol
QC2.0 is Quick Charge 2.0 technology. It is the 2.0 version of fast charging technology released by Qualcomm. QC2 .0 technology had already integrated a fast charging solution when Qualcomm launched the Snapdragon 800 in 2013. There are fast charging chargers that support mobile phones and other mobile devices with QC2.0 protocol for fast charging.
The charger based on the QC2.0 protocol can output four voltage groups of 5V, 9V, 12V, and 20V, and has two standards: ClassA and ClassB. The ClassA standard QC2.0 protocol supports three voltage groups of 5V, 9V, and 12V, and the ClassB standard QC2.0 protocol supports four voltage output groups of 5V, 9V, 12V, and 20V. Since 20V is not commonly used, the chargers and power banks currently on the market are mainly based on the ClassA standard.
PD fast charging protocol
pd fast charging is a fast charging specification developed by the USB-IF organization and is currently the mainstream One of the fast charging protocols.
The USB-PD fast charging protocol is output through the Type-C interface, but it cannot be said that having a Type-C interface necessarily supports USB-PD protocol fast charging.
It can increase the current default maximum power of 5V/2A type-c interface to 100W. At the same time, Google announced that the fast charging protocol equipped with mobile phones above Android 7.0 must support the PD protocol, aiming to unify the fast charging market. .
PD charging protocol is a power transfer protocol announced by the USB-IF organization. It can increase the current default maximum power of 5V/2A type-c interface to 100W. At the same time, Google announced that mobile phones above Android7.0 will be equipped with The fast charging protocol must support the PD protocol, which is intended to unify the fast charging market.
