The Starlink is a power hog. Plugging the Starlink router into A/C sucks even more power than the Starlink uses because of the loss from using the inverter when converting from DC.
Yea… no. Built my own camper, paid meticulous attention to A/C usage vs all other usages (inc Starlink). The RV Starlink at least uses around 100W during heavy usage (hd video streaming). My A/C? 1400W. There is an efficiency loss with an inverter but it’s negligible at these wattages.
