UCTRONICS produces reliable PoE splitters to add Power over Ethernet support to 5V USB-C 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 USB-C power supply. It’s designed for 5V USB-C devices to be powered over Ethernet cables for powerline adapting 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.
