DSLRKIT Gigabit USB Type C Active PoE Splitter 48V to 5V IEEE802.3af Power Over Ethernet for Raspberry Pi 4 4B

Sold as a gigabit adapter, but 1G auto or forced negotiation wont bring the link up. Forcing 100M/Full brought up the connection - but seeing ~20% packet loss across the adapter. PoE support works fine, no issues powering a raspberry pi. With the terrible network performance, this adapter is functionally useless

Both ethernet and USB-C worked to power up pi 4

Works great with raspberry pi 4

Works good

So this will work with a RasPI 4... BUT it is only 2.4A not 3-4A like AC adapters for the RasPI 4. The result is that it will power the 4, but there may not be enough power to fully power the board and performance may suffer or you may have stability issues. This is why I get warnings from OctoPrint that there isnt enough power. Honestly, this would get 5 stars but this was marked specifically for the RasPI 4 and for that its just not good enough. That said, it really does depend on what you are using your PI for... it might be fine.

Im using these devices to power a bunch of PiKVMs since I couldnt get a POE HAT to fit inside the metal box. So this product takes a POE (802.3af) connection, which is a 12.5W standard and splits that out to power (USB) and regular non-POE Ethernet (RJ45). There is nothing to configure, just plug the devices in and ensure the input side has POE enabled at the switch/router/POE injector side.

Mine powered my RPi4 up right out of the bag, and so far, no issues. My Edgeswitch powered it automatically, and shows 1Gb connection. I looked at a lot of case & POE hat options, before seeing the Argon One & deciding that was the way I wanted to go. It doesnt allow for POE though. This isnt quite as sleek, but it is way more versatile!

I use this spitter for my helium miner in order to power and connect to the network with one cable. Works great! saves a whole other cable run on the roof. A+

Got this to use with a backup internet modem that uses USB-C 5V....the power works fine but nothing I do makes the Ethernet link up. Useless. Exchanged for another and the replacement is also DOA and wont pass network to anything. Now I have 2 to return.

I got 3 of these to use with my Google WiFi mesh nodes, and they worked brilliantly! They each have a link light and what looks like an activity light, but that never flashes. My switch is an Aruba S2500. This has been a really nice, cost effective way to reduce cable clutter.
