Wall Plug POE Injector with 48v Power Supply 802.3af for Most Cisco/Polycom/Aastra Phones and More

I needed a way to power PoE+ devices without actually hooking them in to my switch. This does great! I was able to power a unifi access point to reset it no problem. This is not going to allow a high-speed connection through it so don't expect modern throughput. If you just need to quickly power some PoE devices on your workbench, this is perfect and soooo cheap.

Ok

Initially I was going to return this as my procrastination prevented me from even testing if it worked. After finally buying a POE splitter I can confirm it does.It's only 10/100, which I don't even remember if I had read that, but for my needs gigabit is not even an option for me right now.I'm in a rural area using lte for my internet (and communication) needs. I have a few devices for this, but one in particular is the only one that works indoors, the rest have to be placed outside, which gives me constant anxiety. This injector is allowing me to place things outside, in a protected box, without the need of an extension cord that runs the length of my home just inviting the for a disaster in of itself.I placed a weatherproof box outside, installed an lte device attached to a poe splitter, ran a concealed cable inside straight to this plug. Viola, power! My speeds are criminally low, but so much better reception outside, and my internal network is run by other devices so speed isn't an issue on lan.Things I can't speak to:Speed- it works great for my rural needs.Power- it provides just enough to run a netgear M1, but nothing else (attached a travel router to the M1 and it didn't receive any power. To be honest, I can't remember if it does on a regular plug)The 48v thing?- This goes to a poe splitter that apparently handles that.Overall, a good choice for simple devices. Low footprint is definitely a plus.

It was my first time trying to use PoE. It is certainly easy to use - pretty much plug and play - and the price was reasonable, but it just didn't work... I was using a converter on the other end (from a different brand) to go back to a barrel jack, but the device just wouldn't power on.Plugged it back in with a standard plug, and it worked fine. V and everything lined up, it was specifically a PoE-capable device so I was left scratching my head.I ended up calling it a day and buying an extension cord. I'm giving it 4 stars because if it works for you, it seems like a great product by everything that I saw (build quality, ease of use, cables fit well and retained correctly), but it just didn't work for me.I'm assuming they aren't just selling a product that doesn't work, so whether I got a defective one, or a defective adapter on the other end, or a bad cable, I really can't say, but I was just needing the project done so I never did find out.

nice from factor. used to replace a defective POW injector. this one is better bc it fits up against the outlrt.

It only power 1 item I got it to connect 2 wifi thru poe but it only supports power to first item the 2nd connection didn't receive any power. Very easy to connect,nice size

Works well with my Polycom vvx311 iP phone

They work fine for standard 48v POE devices. You can't use it for 24v devices, there are other POE Plugs for that, just search it and you will find. The difference is simple; the 802.3af/at standard requires the port to test for power requirement BEFORE applying power, as such, power is NOT always available at the port. Passive POE is not really 802.3af/at compliant because it allows for power to be present at the port at all times. I prefer the safeguard of "test before application" so I never use passive POE for mission critical devices like AP's or VOIP Phones, Security Cams, etc. In fact, for my commercial and industrial installations I ONLY use 48v POE devices that are 802.3af/at compliant and refrain from passive application of power. I use these specific Plugs for quick replacement of manufacturer POE injectors which have failed and cannot be replaced easily overnight or fast ship. I keep 48v and 24v models on the shelf.
