Gigabit PoE Splitter Adapter,12V 2A Output,1000Mbps, IEEE 802.3AF/at, Suitable for IP Cameras, AP WiFi, IP Phones, and Other DC Power Supply Devices,5.5x2.1mm DC, Input Voltage48-52V,2 Pack

These adapters work very well and are very affordable, and support 1Gbps (not all of these do) highly recommend them. Made my Deco M5 PoE aware.Note: these are 12v and tip is positive on the barrel adapter

These poe splitters work well at a fair price for 2 of them.

I wasn't sure what I'd use these 24W adapters for when I ordered them, but I've wanted/needed cannon-plug power supplies recently and figured I'd grab them. Turns out they work quite well with the slimmer Beelink mini-PCs (usually 12V 1.5A. I have a stack of these, and a healthy disdain for rats' nests of wall warts, so plugging a couple into a small PoE switch will do wonders for cable management and wall space. I even used a 75' Ethernet cable (to go about 3 feet from the switch) and didn't notice any issues. But I'd recommend a much shorter cable.

My router was happy and so was I.

These units work great. I tested these on a BeeLink T4 Mini PC. I checked the voltage with a voltmeter first to make sure they are at 12v and they were. I then used them to power up the BeeLink T4 Mini PC. The mini pc comes with a 12v 2A wall wart. I use these mini PC at remote locations in order to have remote access to that network and this unit allows me to reboot the PC by turning off the POE to the port it is connected to and then turn it back on. They do report to the PC that they are passing a gigabit link. I did get these a part of the Vine program, but have since ordered more thru my work for use at remote locations and so far they are working just fine. I have not tested if they will actually pass 2 amps, but as long as they power the mini pc's I use I am very happy with them. I can recomend this POE adapter splitter.

Power over Ethernet is a really great way to streamline a network of small devices, and I'm currently using it to setup a private home security system I can run from a single outlet with a dedicated UPS backup battery bank for power outages. Managing everything from the one source with backup power is just SO MUCH more fail-safe than losing half or more of the network every time a storm happens. My cameras are all PoE already, but I'm also using some repurposed mini-client PCs as DVRs to stream the security footage to and into my personal cloud from with open-source software, and I needed splitters like these to make deploying the mini-PCs as simple and single-source powered as setting up the cameras themselves was.The plug size of these splitters fits my mini-PCs' power needs, both the physical ports and required wattage just fine. The splitters do get slightly warm to the touch after an hour of use or so, but nothing too bad, and the power and data I get from them is rock-solid-reliable. I've never had a unit drop out and reboot on me once so far, even running continuously for a few days now.I also like that these splitters have the usual indicator lights for power and data. In some cases it might seem redundant, but my mini-PCs actually don't have Ethernet indicator LEDs on their ports, and these splitters let me glance over and verify power and data are working when the glow-less ports on their own wouldn't.These splitters allow getting power to run a non-PoE device from the PoE connection while still having data connected, but I've tried it and they also work without the data part for just the power, so they're really useful as simple power adapters off of the PoE cables. The 12V 2.1mm plug is used in a lot of routers, and I'm actually able to power the router that controls my PoE switch from the switch itself using one of these with the data end of this left unused, and my router's data cable plugged instead into the switch's UpLink port. Literally EVERYTHING in the network is now running off of the battery backed PoE switch- the cameras, mini-clients, and even the router itself, thanks to these handy splitters!These are simple, reliable, and have let me do away with the hassle and risk of multiple additional power supplies for every little thing. I can't even begin to say how darn useful these have been! I'm VERY happy with them, and they have DECIDEDLY earned a 5-star rating from me!

So I just finished reviewing an outdoor POE Extender that I used with one of these kits for my Industrial PC. Before I get into that, I'll give you the quick and dirty -- These are perfect for the Industrial PC I'm using. I've got a setup where I'm using a POE Switch, a gigabit POE Extender, and this adapter to power my Industrial PC ~ 175 ft away from my office.This adapter converts the POE extender into both a Network connection and a 12 VDC power source for my Industrial PC. It makes running the Industrial PC significantly easier since I don't have permanent power at the building yet.Pros:- Plug and Play- Splits to Power and Network- Easy to Use- Works perfectly for the Industrial PC I'm usingCons:- I haven't found any yetI've got a few more projects coming up where we'll be providing equipment and cabling for some controls work. All of our switches are POE and these make it so much easier to wrap everything up nice and easy. I'll be ordering more to keep my enclosures clean. Highly recommended.

Important things first. Do not expect this to reliably deliver 2 amps, unless you keep it extra cool. While I didn't look up the datasheet on the parts used, I have in the past, and I have found this type of PoE splitter to only reliably support 1 amp, and other splitters by reputable companies only claim 1 amp. Granted the insides can be different, and that's true, but in line with Chinese manufacturers overrating their equipment, I'm sure this one is no different. But the devil is in the details. High current doesn't kill electronics. Heat kills electronics. So, if you keep the parts cool, they can run at a higher current. This PoE splitter is no different from any other electronics device in that respect. So, you could use this at 2 amps, all day long, and have it be perfectly reliable...if you keep it someplace cool, like maybe a walk-in refrigerator for example. But don't expect this to last too long if you always draw 2 amps.1 amp = safe1.5 amps = you're pushing it, and will probably shorten the life2 amps = probably won't last more than a few weeks, to a few months.I feel the price is reasonable on these PoE splitter/adapter, and ignoring the fact their claims are overrated, I can recommend these.
