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

I bought 3 of these adapters and they all work, and work the same way. They do what I need, 5V @ >1A.Pro:— Runs Raspberry Pi 4 @5W, required for boot-up and heavy processing (all 4-cores @100%)— Works with Raspberry Pi 4 Pre-v1.2 USB-C connectors (CC lines wired together, not separate as required, newer RP4's do it right)— Convenient small size, light weight— Will charge my cell phone using a µ-USB adapter— Provides the higher current needed to run the RP4 reliably. My laptop Type-A USB ports don't provide enough power, and my pre-v1.2 RP4 won't power off the USB-C port, because it is wired incorrectly. This makes this higher power adapter necessary for my application(s).Con:— USB-C is 5V only, won't negotiate to higher voltages.— No real con, except the green light on the Ethernet port never lights. I couldn't decide if this is an Ethernet activity light, or a USB-C connected light. Either way, nothing I do makes this light turn on. Wondering what it's for?

I have an MR6400 Netgear 5G modem I wanted to run on PoE. This adapter worked with my Unifi USW-Pro-48-PoE switch and powered the modem perfectly. Would recommend.

Got these so I could use PoE with 5 x 1st gen Google WiFi points. My house is wired for cat 5E so I was able to power them from a central location using a PoE switch and have a UPS connected to the switch so they don't go out when the power flickers in my rural area. So far it works great and the speeds did not change.

I have several Unifi wifi cameras on our home security system that I want installed but as one might expect, where I want them I don't have power. Came across these while doing some research and according to the spec sheet, the splitter plugs into the camera and my ethernet cable into the back. Should be quick and easy and a test on my work bench was a success with my Unifi system recognizing and adopting the camera. Saves me a bit of money as the Unifi wired cameras are a bit more and currently out of stock.

I got this to run POE with my Rak V2 hotspot miner. The splitter is compact and plug and play. The cable front the injector plugs right in to the splitter and from there the USB C plugs directly to the hotspot. Clean setup and perfect for outdoor setup allowing the hotspot to be mounted closer to the antenna. So far everything's works and no issues.

Powers my nebra helium miner with no issues in the attic. I didn't want to have to wire or run electricity in my attic and this allowed me to use a poe switch and power the miner.

This device has NO PROTECTION against current on the ground circuit! We were using this to power remote streaming devices in several rooms. A couple of these rooms have self-powered speakers (built-in amplifiers) that connected to the streaming device (powered by these adapters). Power was able to flow from the PoE switch, through the adapter to the ground of the device, then from that device's ground back to the AC ground of the house!These should NOT allow current to flow through the ground/shielding on the PoE cable! It would have been preferable that the ground/shielding was not connected, rather than risking a fire by allowing current to travel back it to ground.DO NOT use these devices to power anything that will be connected to another device that has it's own power. It can cause a fire!!

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.
