TP-Link 802.3at/af Gigabit PoE Injector , Non-PoE to PoE Adapter, supplies up to 15.4W, LED Indicator,Plug & Play , Desktop/Wall-Mount ,Distance Up to 100m, Black (PoE150S)

I've used these in various places with no issues at all. They have powered unifi APs, meraki APs, point to point link stations, cameras etc and never missed a beat. Even in some harsh conditions kept in IP rated boxes in the middle of nowhere during cold winters and hot summers. For the price of them they just work and are cheaper than the genuine ones if you're buying in bulk.

I ordered a couple of these to test with a D-Link DGS 1210-10p POE Gigabit managed switchThe intention was to power a GuruPlug and SheevaPlug which had their internal psu's ripped out and were running on external 5V usb chargers (good mod to do anyway with the overheat prone plug computers)I'm very pleased to say they work, worked first time, and haven't shown any indication to do otherwise (will update if things go awry). GuruPlug and SheevaPlug humming away nicelyThey are small and discrete certainly smaller than your trad psu brick and will be very much more efficient than an old transformer type psu, and being shiny piano black they even look nice - higher than avg WAFI've put one on a Linksys PAP2 voip adapter (aka Cisco SPA2000 or similar to SPA3000 et al) and it works like a charmI've liked them so much I've ordered another 3 - can't go wrong with them being £10 a pop!other advantages of course are that I can now (given a managed POE switch) remote powercycle my kitadditionally they do allow the ethernet ports to sync at 1000bT speeds if you have a gig networkperfect to power those remote WIFI AP, cameras or as in this case even small computers - imagine powering a RaspberryPI at the end of a 100m cat5e ... excellentfinal comments : they work, comply with 802.3af, are small, switchable 5v 9v and 12v, give gigabit speeds (if you have the network) and seems to stay cool to touch and 3yrs TP-Link warranty100% recommended by this customer :)

I've been using devices with POE receivers built in for a couple of years, but wanted to expand the usage to devices that don't have that function. Now I can use one, easy to install, CAT5 cable to install wireless access points and other (low power) network equipment anywhere in my house or garden without having to compromise on the functionality of the device because it doesn't have POE built in.The unit's about the size of a cigarette packet, with a polished plastic case. One end has a lan port which you plug into the network, and a stepper switch that goes from 5v, to 9v, to 12v. The other end has a lan port that connects to your device, a power output socket, and a LED to indicate the unit is working.It is a lot more discrete that the Trendnet TPE-104S, in both size and the fact the Trendnet has an LED to indicate which power setting has been selected and another to show the unit is working, both on the top of the unit, while this TP-Link unit has its LED on the back, so it's out the way.It does lack fixing brackets, but I'm using sticky feet to attach it to my wireless access point, meaning I can move it to where I need it rather than to the wall.If you already have an IEEE 802.3af compatible network, this is very useful and cheaper option than the competition, perfect for home users.Edit: been in use constantly for over six months, connected to a Linksys switch/wifi access point in a spare room. No issues, and no need to run extra cables as already had a Cat5 cable arriving from PoE hub.

Using this in my church network to power a Draytek Vigor 130 modem from a Ubiquiti POE switch some distance away, so that its power is also covered by the main rack's APC UPS.The device is tiny, lightweight and works perfectly: set the switch to 12V (or whatever you need), plug in the Ethernet and power plugs, and you're away.Dropped one star on the rating for a couple of minor points:1. No easy mounting point. It's very light and can just hang on the cables, but some keyhole slots would help for a neat installation on the wall.2. Supplied DC power cable is short with 2.1mm plugs on both ends. This will fit many devices, but for my modem I needed to cut off one of these plugs and solder on a 2.5mm plug instead. Would have been nice to include a multi-adapter like many mains DC power supplies ("wall warts") include.

I bought this to power my wireless access point downstairs through an ethernet cable.The setup (which consists of plugging it in and providing power) was extremely quick and easy and it worked immediately.The only thing I would say is in the description it states "The wall mount and desktop design are suitable for most installation scenarios", which I took to mean a wall mounting plate might be included in the box, or the case was removable in some way to gain access to mounting screw, but that's not the case. There are grooves on the sides which imply it could be slid into a mounting plate, but none is provided. Other than using some form of adhesive to stick it to the wall there is no way to mount it.It's not a big issue but I thought it was slightly misleading and worth pointing out to other potential buyers.
