UPDATE: I have confirmed with MobileMustHave that the USB C port on their converter is powered at 5V, 3 amps, which is a PERFECT fit power supply for the GL-iNet Beryl AX router. I can just tap the wires going to the 12V port in the attic to power their POE converter, then plug the Beryl AX into the USB C port on the converter. That will get me a 100% DC solution off the camper batteries and I only have to send out a single ethernet cable to the Starlink Mini dish, through the existing satellite coax port on the Ollie. I can then save my Starlink power cable for other applications when using it away from the camper.
