48V 0.5A PoE Injector Power Over Ethernet Adapter For Wireless Access
A part of the review has been auto-translated.
My POE model POE-4800500 was dead on arrival : (( no sense in sending it back from the Netherlands >> to China.... so ordered a 2nd one. Hoop that works!
Was originally a little concerned about the very low price of the unit and the length of some of the cable runs that it would be putting POE over. Over ~30m absolutely no issue. The lights on the connected device (phone) don't even dim when receiving a call anymore (which they did with the official adapter)
The device works perfectly with a Yealink T22P phone. Kudos for including the US to EU power adapter in the package, I was not expecting that.
Its good thank you
Please note that this unit puts power on the 2 unused twisted pairs (pin 4&5 , 7&8) In the products description this is described as usage number one. For this price you get good quality.
