What is USB-C with Power Delivery (PD)?

USB-C and Power Delivery: Two Separate Concepts

USB-C / USB Type-C
When considering "USB-C," think of the "C" as standing for "Connector," not to be confused with what some might jokingly refer to as "USB-Confusion" (a playful term coined by the DocKtor).

In reality, the term “USB-C” refers specifically to the connector (the plug or receptacle) and not the capabilities of the system. USB-C can support Power Delivery, Alternate Modes (including Thunderbolt), or just one of the USB specifications, or it may support something else entirely. However, it’s important to note that not all USB-C ports necessarily support Power Delivery. The connector itself is versatile, but its capabilities depend on the specific device or system.

Power Delivery (PD)
Power Delivery (PD) is a distinct specification that uses the USB-C connector to deliver power (voltage and direct current). While USB-C doesn’t have to include Power Delivery, Power Delivery always requires a USB-C connector to function.

The latest version of the Power Delivery specification is PD 3.1, which can provide up to 48V at 5A (240W DC). This is the maximum supported power, but it is not required for all PD 3.1 compliant power supplies. Many PD 3.0 and PD 2.0 devices are still commonly used, often with much lower power requirements (such as 100W DC).

Key Points to Remember

• Not all USB-C ports support Power Delivery, so it’s essential to check the device documentation to confirm.
• Charging speed depends on both the Power Delivery supply and the device.
• Some devices may require specific types of USB-C cables to support Power Delivery.
• Targus and Hyper offer power supplies, chargers, battery packs, and docking stations that are compliant with PD 3.1, PD 3.0, and PD 2.0.
