Power Delivery Standards

All Power Delivery standard versions with speeds, features, and compatibility.

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

4/10

Power Delivery specification supporting up to 100W (20V/5A). Introduced programmable power supply profiles for laptops and high-power devices.

USB PD 3.0

5/10

Added Programmable Power Supply (PPS) for optimized charging with granular voltage/current control. Required by Samsung Super Fast Charging and other adaptive charging protocols.

USB PD 3.1

8/10

Extended Power Range up to 240W (48V/5A). Enables USB-C charging for gaming laptops, studio displays, and even some desktop PCs.

Qualcomm Quick Charge 5.0

4/10

Qualcomm's proprietary fast charging at 100W+ with battery temperature management. Can charge 0-50%% in 5 minutes on compatible phones. Works alongside USB PD.
