ANVISION 4-Pack Active 5V 2.4A PoE Splitter Adapter IEEE 802.3af Compliant Micro USB 48V to 5V/2.4A, for Tablets, Dropcam or Raspberry Pi, IPC, IP Camera and More

Used all four and they worked well for several months. Then one failed. Contacted Anvision and they refunded the cost of the failed splitter. Still the best deal on micro USB splitters.4/5 stars for the product, +1 for Anvision refunding the failed one.

Edit: May 23, 2019 – Been using these for a while now and they work great; however, they do cause interference on garage door openers (300mhz?). I had to remove it so my opener would work reliably again.Seems to power ok, but the micro USB plug is huge, so it won't fit into anything that's inset, like the Wyze Cam. However, I cut away some of the top and bottom using a razor knife and it fit perfectly and powered the Wyze Cam just fine.Just know that out of the box, the plug is too big. It's an easy fix though. This is also what the manufacturer/seller recommended I do.

Worked great! Love them.

I bought two sets of these to power Raspberry Pi's, I am using Ubiquiti Managed POE switches. They immediately worked with the POE+ power sensing. (Some versions of firmware have POE disabled by default so check this if your having problems with these switches)However I didn't have a network connection. I needed to change the port settings on the switch from "auto detect Link speed" to manual and then "100mbit". Once I did this after 30seconds to 1minute the link light on the raspberry Pi's network interface then came on.Works fine with my -pi 1 b+pi 2pi zeropi zero Wpi 3+

The rental house was rigged with POE camera that I didn’t have access too. This easily convert the POE Ethernet to microUSB. It is able to run my Wyze V3 without any issues.

I’ve use these several times. And they seem to work very well as far as longevity I’ve had about 10% of them fail on me

Inconsistent voltage/amperage across the splitter, I had to replace 3 times then I gave up and got a different PoE splitter from another seller, and those work flawlessly than this one! Get the "UCTRONICS PoE Splitter Gigabit 5V - Micro USB Power and Ethernet to Raspberry Pi 3B+, Work with Echo Dot, Most Micro USB Security Camera and Tablet - IEEE 802.3af Compliant" (product ID B07CNKX14C) instead of this. This 4-pk version was just a nightmare. I could not get the Raspberry Pi 3B+ to run at 100%, since the power LED kept going out and occasionally blinking. 1 out of 4 PoE splitter might work, but that's abysmal if you ask me. I expect all 4 to work, not just 1.

I'm using these to run Raspberry Pi computers in buildings to do envronmental monitoring and security. The devices are small and easily fit in the electrical box with the pi and interface boards. They provide the full current the pi needs and run perfectly well on POE ports from my Cisco swithches. They only pass 100 Megabit ethernet but that's fine since it's all the pi can do anyhow.,
