About PD fast charging manufacturers in china
PD stands for Power Supply. PD technology basically allows your device to get more power in less time, which means super fast charging. Many of the most popular mobile devices, including iPhone and Galaxy devices, support PD.
Power Delivery (PD) is a specification for handling higher power that allows a range of devices to be quickly charged over a USB connection. It works by facilitating a conversation between two devices to negotiate a power contract so they can determine how much power can be drawn from the charger.
PD was created as a single standard to power various USB gadgets. This reduces the need for proprietary ports, connectors and plugs.
