I can. At present, there are two kinds of fast charging technology for mobile phones, which are high voltage fast charging and low voltage fast charging.
High voltage fast charge generally refers to the 9V\/2A or 12V\/2A power adapter for charging, this charging method is fast, but there is also a problem of easy heating. The main applications of this technology are Qualcomm QC fast charge and Mediatek PEP fast charge.
As the name suggests, low voltage fast charge is the ordinary charger on the market, generally 5V\/2A,5V\/1A,5V\/4A and so on. The advantage of this charging method is low heat.
There are three forms of fast charging: 1, the voltage is unchanged, improve the current. 2, the current is unchanged, increase the voltage. 3, the voltage and current are increased.
Mobile phone to achieve fast charging, can not only improve the voltage and current on the line, but also need a set of perfect circuit, battery, interface, data cable and adapter, etc., but also need to do a set of intelligent power management system, so that the mobile phone according to different occasions, adjust the voltage and current to ensure the normal charging of the mobile phone! . The technology used by fast charging mobile phones is different, Apple mobile phones generally use pd fast charging protocol, while Huawei uses fcp protocol, Xiaomi and ov and some other brands use qc protocol, all protocols are accompanied by a common feature, that is, downward compatible 5v voltage standard charger, that is, you can use 5v low-voltage charger to charge. Charge a little slower, but the battery lasts longer!
Yes, fast charging mobile phones can be used with ordinary chargers, but it may be slower when charging.
