TP-Link TL-POE160S 30W PoE+ Injector _MAKE_MODULE_ADAPTERS and includes protection diodes soThis PoE+ Injector from TP Link fully complies with IEEE 802. 3af at standards supplying up to 30W, and can work with all IEEE 802. 3af at PoE compliant PoE equipment such as many of the PoE HATs and add ons we stock for the Raspberry Pi. If your router or network switch doesn't offer PoE injected Ethernet lines, this injector will allow you to 'inject' any Ethernet cable to provide both power and a network connection popular for Raspberry Pi
