Review on ICreatin Wall Plug POE Injector With 48V Power Supply 802 by Eric Pruett

Despite the description, this is not an 802.3af device. I am giving a 1 star rating because the description is incorrect. If you need 802.3af, this isn't for you. iCreatin Wall Plug POE Injector with 48V Power Supply, 802.3af for Most Cisco/Polycom/Aastra et al Phones sold by Plus Tech Ltd from 8th April 2015 What is the difference between Passive and Active PoE? (Source Tycon)A: Passive PoE always has power on the port. The voltage can be between 12 VDC and 57 VDC. Active PoE conforms to IEEE 802.3af or specifications. It only powers the port when a valid client is connected. The voltage is only 48V to 57V DC.
