What is a PD charger?
A Fast Charger with PD technology
Currently, two mainstream fast-charging technologies are on the market: the first is QC (Quick Charge), and the other is the more recent PD (Power Delivery Charger). PD chargers are one of the fast-charging protocols released by the USB-IF that are aimed to provide a more efficient charging technology than traditional charging methods. The new generation of PD chargers can use the PPS feature to perfectly integrate QC and satisfy the need for fast charging. In addition to supporting a variety of output voltages and currents, PD chargers also support 3C devices such as mobile phones, cameras, and laptops as the usage scope becomes more and more extensive.
