Power Delivery 标准

所有 Power Delivery 标准版本及速度、功能和兼容性。

Power Delivery standards define how devices negotiate and deliver electrical power over USB-C connections. USB PD 3.1 introduced Extended Power Range (EPR) with 28V, 36V, and 48V fixed voltages, enabling up to 240W delivery. Programmable Power Supply (PPS) allows fine-grained voltage adjustment for optimal charging efficiency. Qualcomm Quick Charge and other proprietary fast-charging protocols coexist but are increasingly converging with USB PD.

USB PD 2.0

功率传输规范，支持最高100W (20V/5A)。为笔记本电脑和高功耗设备引入可编程电源配置文件。

USB PD 3.0

添加可编程电源(PPS)，通过精细的电压/电流控制优化充电。Samsung超级快充和其他自适应充电协议的必需功能。

USB PD 3.1

扩展功率范围至240W (48V/5A)。支持游戏笔记本、专业显示器甚至部分台式机的USB-C充电。

Qualcomm Quick Charge 5.0

Qualcomm专有的100W+快充技术，具备电池温度管理功能。兼容手机可在5分钟内从0充至50%%。与USB PD协同工作。
