How to maximize the fast charging effect?
Fast charging can be understood literally, that is, to improve the charging speed of mobile phones. So how does it come about? The principle is also very simple and easy to understand. Fast charging uses the chipset to adjust the input voltage and current value of the mobile phone, thereby shortening the charging time. It is common to increase the charging speed of the mobile phone by increasing the voltage constant current, low voltage high current and high voltage high current.
