The PD blocker removes Power Delivery (PD) capabilities from USB-C connections and provides over-voltage protection.
Some USB-C devices do not require the Power Delivery features available on USB-C, mainly higher voltage and current. The device could not even be rated for higher voltages. But chargers might be stuck at higher voltage, or mischievous eMarked cables (with PD-capable chips built in) could raise the voltage, permanently damaging it.
The PD blocker protects your [expensive] USB-C device from such damages.
Insert the PD blocker in line, between the power source (e.g. charger or host computer), cable, and your device. It can be inserted between any two of these components, and will work the same. Plug and receptacle can be either side, and it is reversible along the axis of the connectors (like normal USB-C connectors).
The PD blocker will prevent any Power Delivery communication, such as raising the voltage. And when over-voltage is detected (Vbus > 5.5V), power is cut and an OVP LED indicating the culprit side lights up. Connect the PD blocker before the target device for the protection to take effect before it can reach it.
All other features of USB-C are preserved (e.g. USB2, USB3, USB4, SBU, orientation detection). Some alternate modes requiring PD communication will not work anymore though.
