Review on UCTRONICS PoE Splitter USB-C 5V - Active PoE to USB-C Adapter: For Raspberry Pi 4, Google WiFi, Security Cameras, and More by Carl Morgan

Easy to install, works with my Netgear GS716TPP to power my Raspberry Pi 4b and doesn't interfere with any cooling system I want to tweak or need a hat . Untested, but presumably I can turn my Raspberry Pi on and off with a switch, which would probably be very useful. At first I thought the adapter might be a nuisance, but I think it can easily be tethered to my DIN rail. I mount everything on Pis. The only complaint is that I wish the adapter was cheaper, but it works for a couple of devices that I'll probably set up.
