UCTRONICS produces reliable PoE splitters to add Power over Ethernet support to DC 5V devices. PoE splitters save USB adapter wall plugs, extend power line to where your Ethernet cable reaches, and make full use of the extra PoE ports by converting them to 5V power supply.
This adapter is designed for both 5V USB-C and 5.5x2.1mm barrel port devices to be powered over Ethernet cables, for powerline adaptation or extension. We recommend you use this item with IEEE 802.3at compliant PoE switches or injectors. It works with 802.3af PoE equipment but will output less power.
