Review on DSLRKIT Gigabit USB-C Active PoE Splitter 48V to 5V IEEE802.3af Power Over Ethernet for Raspberry Pi 4 4B by Todd Hauff

I can also confirm that it works with Original Google WiFi Meshes with no issues. In combination with a 4-port PoE switch, I reduced the number of pucks from 4 to 2. My parents built a house in the 60's so everything is secure including every door in the house. If you move one down the hall, PoE powered with this adapter, the speed in the living room jumped from around 100Mbps to over 500Mbps, only slightly slower than wired. I also plugged it into the main puck/router so it connects to the internet/modem to the main puck (no poe) and then to the lab port on the puck. I have an adapter that plugs into the poe switch for power. Works flawlessly.
