Review on Pastall Raspberry Power Switch Female by Jennifer Costa

I am adding an asterisk because these switches seem fairly standard and I assume they will work for the Raspberry Pis. However, the design isn't very useful as you still need a dedicated Raspberry Pi power supply. TL; DR: Your optional 18W phone chargers (PD) will not work with this. A non-Pi device will be confused at how much current it can draw and charge slowly. I would only suggest these for: 1) a Pi 4 power bank that doesn't have a switch 2) a (good and powerful) USB-A charger with a USB-A to USB-C cable 3) some of the very earliest USB phone chargers -C (non-PD Type-C power does not exceed 15W). There are two problems here: 1) The switch itself has a 56kΩ pullup resistor on one of its CCs. This completely breaks Type-C and overrides any actual power of the block to be the lowest available (1.5A = 7.5W). 2) The input port does not have a 5kΩ pull-up resistor on any of its CCs. This means that PD power supplies (and smarter non-PD power supplies) won't deliver power because they don't recognize the device.
