Adafruit USB C PD to 2.1mm Cable with Selectable Voltage Button

This USB C PD to 2.1mm Cable with Selectable Voltage Button maximizes your USB C Power Delivery wall warts' potential by allowing you to choose among available voltages to power any device with a 5.5mm outer diameter and 2.1mm inner diameter DC plug. Simplify your power solutions by replacing numerous adapters with this versatile cable.

With a satisfying button, convert any USB Type C adapter with Power Delivery support into a 5V, 9V, 12V, 15V, or 20V DC power port with up to 2 Amps output. It features a PD sink negotiation chip, a 7-segment display output, and a button input. This setup enables the cable to coordinate with the PD source chip to adjust the voltage output under your command.

Each click of the button increases the voltage: 5V, 9V, 12V, 15V, and 20V. Remember to check your adapter's voltage and current capabilities, as some PD power supplies might lack 12V or 20V support. This 1-meter cable comes with a 5.5mm outer diameter and 2.5mm inner diameter tip with center positive voltage, which is the most common setup.

For center-negative configurations, use 5.5mm/2.1mm DC Barrel Polarity Reversing Cable Adapters. The cable defaults to 5V upon connection and allows voltage increase with repeated button presses. Ideal for those needing flexible voltage solutions, while fixed voltage users might prefer fixed-output cables.
