Review on UCTRONICS Raspberry Pi 4 Power Supply with Switch - 5V 3A USB Type C Charger Adapter, Black - Includes 3.3ft ON/Off Switch Cable by Aaron Jensen

So I was looking for a USB-C power button for a non-Pi device. Here's what I found out after some wiring and digging. In short, this cable works for the Pi but is not compatible with other USB-C devices that use USB Power Deliver (PD). Longer story: The Raspberry Pi accepts "dumb power" with just two pairs of wires connected to the USB 2.0 power lines. With USB PD, you need to connect the CC lines to allow the charger and the device to negotiate the power contract. The absence of CC lines means that USB-C devices comply with the PD specification. does not work with this device. Two stars for the technical work done with the Pi, but this device is not USB-C compliant and I didn't see that information in the device description.
