PoE Splitter with MicroUSB Plug - Isolated 12W - 5V 2.4A

802.3af PoE splitter that separates the combined power and data from an RJ45 PoE input into a standard Ethernet data port and a 5 VDC / 2.4 A Micro-USB power output. Isolated 12 W design; adds PoE power delivery to any non-PoE Ethernet device.
