Difference: The charging speed of PD charging cable is faster; while the charging speed of ordinary charging cable is slower. The PD charging cable will automatically stop charging after the charging is completed, making the entire charging process safe and efficient; the ordinary charging cable will automatically switch to trickle charging state after the charging is completed.

The difference between pd charging cable and ordinary charging cable
1. Charging speed:
The pd charging cable integrates quasi-resonant current Mode controllers and power MOSFETs have the characteristics of high performance, low standby power consumption, and low cost. However, ordinary charging cables generally have a charging specification of 5V2A and use constant current and constant voltage charging, so the charging speed is slow.
2. After charging is completed, the current is converted:
The chip on the pd charging line can control the charging process and automatically stop charging once it is full, making the entire charging process safe and efficient. The ordinary 5V2A charging standard cable usually automatically switches to trickle charging state after the battery is fully charged.
For the PD charging line, due to the three-mode mixed modulation technology of QR-PWM, QR-PFM, and Burst-mode and the special device low-power structure technology, ultra-low standby power consumption and full Best efficiency across voltage range. At the same time, it provides comprehensive and excellent intelligent protection functions, including output overvoltage protection, periodic overcurrent protection, overload protection, and soft start functions.
For ordinary charging cables, it has fewer peripheral components and is relatively simple. It integrates a 650V high avalanche capability smart power MOSFET internally. The circuit design is simple, easy to implement, and the price is low.
