“This is a Push-on Push-off type and not the rocker type I was expecting. It is Nice. It just cuts power to the Raspberry Pi, it is a hard switch off with no shutdown process if you just use the button to turn off the Raspberry Pi.”
“It works with a Pi4 power supply but not with a Pi5. This should be highlighted. I accept that it is advertised for Pi4 but since both use a "c" connector it was reasonable to expect that it would work with both. The wiring configuration must be different on the 27 watt power supply.”
