Is USB-C Voltage 5V or 9V? Understanding USB-C Power Delivery

Learn if USB-C supports 5V or 9V output and how USB Power Delivery negotiates the right voltage for your device.

0 views

USB-C supports multiple voltage outputs, including both 5V and 9V, making it versatile for different devices' charging needs. The specific output depends on the device's requirements and the charging technology being used, such as USB Power Delivery (PD). Devices negotiate the necessary power delivery, which can range beyond just these two voltages to efficiently charge without causing damage. When selecting chargers and cables, ensure they are compatible with your device's specifications to take full advantage of the USB-C’s capabilities.
