In general, if the mobile phone supports fast charging technology, it will be fully charged faster using direct charging. This is because fast charging technology can improve charging speed and efficiency by optimizing the charging circuit. The universal charger generally does not support fast charging technology, but simply converts the voltage and current output of the ordinary charger into the voltage and current required by the mobile phone, so the charging speed is slow.
However, it should be noted that the use of universal charge may cause damage to the phone battery. Because the output voltage and current of the universal charge are unstable, the voltage and current adjustment ability of the battery may be affected, resulting in shortened battery life or reduced battery performance. Therefore, it is recommended to use an original or certified charger to ensure the health and use experience of the mobile phone battery.
Direct charger is the manufacturer according to the capacity of the mobile phone battery targeted research and development of the charging circuit, the circuit is perfect, reliable, and universal charger is a simple and cheap small step-down circuit, there is no targeting, there is not much protection, so the direct charger is faster than universal charging, and the battery is more full
