UCTRONICS IEEE 802.3af Micro USB Active PoE Splitter Power Over Ethernet 48V to 5V 2.4A for Tablets, Dropcam or Raspberry Pi 2/3B+ (48V to 5V 2.4A)

This has proven to be an excellent choice to power a Raspberry Pi 3b project. I built it inside an enclosure with a 7" LCD screen and this adapter powers both the Pi and the screen using PoE. The application running on my pi is not CPU intensive so I can't comment on how far the power delivery can be stretched, but it has been going for months now without a failure. This was easy to integrate and an inexpensive alternative to the official rPi3b PoE hats that I've seen.

Exactly as described .. works well

This adapter is perfect for a device that does not support POE power out of the box. This adapter is connected to a TPLINK travel router that I am using for all of my alexa IoT devices as those aren't really the best when ut comes to network security. The POE port that the device is using is on a separate Vlan on my switch and it has no issues providing network data as well as power over the Ethernet cable. All in all, works as described.

Order two of these; both provided +5V but one wouldn't pass traffic. Problem moved with the power splitter, so I initiated an exchange with Amazon. Replacement works fine. A minor nit is that these things claim to be 802.3af compliant, but they don't support GigE. This suggests that they may only support Alternative B. I suppose I could ask the switch what they negotiated, but I'm less than motivated at the moment.

Work as described!

Got this to use with a FireStick 4K and it works great. One ethernet line from my PoE switch to this, and then this plugs into the ethernet adapter on the FireStick, providing power and data to the adapter and FireStick. About a clean a set-up as you're gonna get.

Its works fine - I originally tried to use a Ubiquity injector with this. However it didn't work. I thought the problem was this but it was the fact that the Ubiquity injector isn't compatible with this device.

Works great for powering an Intel W5 stick computer from an 802.113af (PoE+) switch Make sure your power source (switch/router) supports PoE+, this will not magically supply power from any old Ethernet switch or router. I use a Ubiquiti EdgeSwitch 24 250W It would be nice if the power cord was an adjustable length or a little longer since I need to connect the Ethernet port to a USB Ethernet dongle causing the power and Ethernet wires to be two different lengths, looking a little clunky, but it’s nit fair to expect the vendor to anticipate this usage. Regardless, it’s just a minor aesthetic issue. It is 100% functional This should power just about any microusb powered device just fine- I’ve used it on a Canary and the Intel W5 so far. This is a true gigabit speed dongle, many others are only 10/100

bought this to replace the one from Aliexpress, about the 2X of the price, order from Aliexpress will take too long, so far so good.

It worked for a year and then broke, better buy from local shops with warranty

If you have an existing Power over Ethernet (PoE) network, this device lets you connect USB-powered devices to it without needing a separate power supply. I used it to add a wireless access point (WAP) to my network in a location that didn't have mains power available for a conventional USB power supply for the WAP. No configuration needed, works straight out of the packet. Quality is o.k. but nothing special. No idea how durable it is, has only been in use for about a month. No problems so far.

PoEは一般的にはまだまだ知られていませんが、PoE HUBを有していてコンセントが不足気味な当方にとって、検証の際に助かっています。 ただ、連続稼働の現場に投入するか、といえば現時点では？です。

replace outdoor camera, but it was powered by POE, bought Wyze camera, so this cable works great cover the PEO to micro USB
