Review: Work really well. Saves on cables - Great idea to turn your standard cat 5 cable unto power over Ethernet. No instructions supplied on how to connect but it's fairly straight forward
Review: Know what you are buying - Anyone saying this these devices cannot possibly work because they are not fully wired is wrong, 10 & 100Mb/s only needs two pairs (Orange & Green) of wires out of the four for Data in a standard Ethernet cable, these devices effective strip out the other two pairs (Blue & Brown) between your network switch & the remotely located device & use these pairs to extend the power, the RJ45 plugs connect into your switch & the same at the remote end, the female RJ45 sockets connect to your cabling between the local & remote locations. You are never going to get Gigabit speeds from these devices as 1Gbs needs all four pairs within the Ethernet cable, I tried mine ovver my longest cable run of around 35m & they worked fine, cabling quality & distance will affect the ability for these to work effectively. I'm using mine to power a 4G/LTE router which is loacted in the loft as that's where it gets the best 4G/LTE signal, I could easily run an Ethernet cable to the loft but not mains power, for me these PoE injector/splitters are a godsend as my 4G speed only peaks at 35Mb/s well within the 100Mb/s that in theory would be possible using these devices. Now for the negative bit, my first set that I ordered were faulty, the injector end had a faulty connection on one of the Data pairs that only worked if the wires were wiggled to get the sweet spot, I ordered another set which were fine & sent back the faulty ones for a refund, luckily I have an Ethernet cabling tester & so I was able to prove what was going on.

## Questions & Answers

**Q: what is the max current?**
A: They don't specify a maximum current but, looking at the size of the conductors they should be happy at 2 amps.

**Q: Hello will this power a virgin superhub 3.0? will the power connector for the back of the super hub?**
A: No. They are designed to add power to a Network cable. Thanks

**Q: Are these for use on POE systems which change the 48 volt down to 12 volt for the camera?**
A: No, these will pass what they are given. If you give them 48v then the device will get 48v.

You need a converter or a step down device for what you are looking for. Or use the cameras standard PSY to supply the power in the first place.

**Q: Will this work for a echo show 5 to be powered by ethernet?**
A: I’m not sure if the power Jack is the correct size or the voltage will be sufficient
