1. What can we do for Fast Charge?
You can understand the fast charging agreement as a secret signal. If you got the password, we will get the secret signal.
For mobile phones and mobile phone wall chargers ,there is also such a password. Only when the password is matched, can the fast charging be carried out. This is the fast charging protocol.
Fast charging is very important for us now. One is slow charging, which can be fully charged in 5 hours, and the other is fast charging, which can be fully charged in 2 hours?
We are all smart people, so there should be no one to fill slowly
Fast charging agreements are not complicated, but there are many kinds of fast charging agreements. Who can remember them?
2. Common fast charging protocols of various mobile phone brands
To understand USB charger fast charging protocols, we need to know mobile phone charging protocols first.
Why the wired charging protocol? As the name implies, using this charging protocol requires you to have a data cable to connect the power bank and mobile phone, which is the most common charging method at present. (Of course, there is also a wireless charging protocol, which will be described later)
Xiaomi/Hongmi mobile phones: Qualcomm QC protocol, Turbo Charge (Xiaomi private protocol)
Apple mobile phones: iPhone 8 and later mobile phones are all PD protocols (before iPhone 8, Apple 2.4A charging protocol is used)
Huawei mobile phones: FCP, SCP (these two are private protocols, currently 18W and 22.5W have been disclosed, but high-power phones such as 66W have not been disclosed)
OPPO: VOOC SuperVOOC (both private protocols), one plus: Warp (private protocols), Realme: DART (private protocols),
Vivo and IQOO: Vivo Flash Charge, Vivo Flash Charge, and Dual Engine Flash Charge (all three are private protocols), are they speechless?
