USB Power Delivery (PD) protocol allows a power source to deliver multi-voltage compared to the single 5V USB voltage. Because of this, a compatible device (usually a mobile phone or laptop) charged faster with a PD charger compared to other non-PD charger. The goal is to use PD as a single standard for powering and charging all USB devices. Ultimately, a PD wall plug or powerbank can be used across all devices. USB PD make use of USB-C reversible connector.

This cable has a USB-C connector on one end and a common 5.5 mm x 2.1 mm, inner positive DC barrel plug on the other end. It has a built-in chip that can "trick" a USB-C PD power supply/power bank to think that it is a PD compatible device and pass up to 15V DC. This cable can be used to power various 15V devices with a DC barrel connector such as a router, Single Board Computer (SBC), speakers etc. It is especially useful when paired with a PD compatible power bank so that you can have a portable 15V power source.

Around 1 to 2 seconds are needed for the cable to "negotiate" with the power supply. So it is recommended to plug the cable to the power supply first and then after a few seconds later plug to the device. Take note that if your power supply does not support 15V PD, the cable will get the next lower voltage that the power supply can give e.g. 12V, 9V or 5V.

Cable length is approximately 1 meter with 18 AWG thickness. Be mindful that this is not a boost cable. Whether or not you can get 15V out of it depends on the Power Delivery capability of the USB-C power source.

Disclaimer:

Use at your own risk. Higher voltage will certainly cause damage if your device is not able to handle it. Always check the voltage with a voltmeter and make sure your device can handle the power that you are connecting it to!
