The lighter socket is the right place to take power as long as you keep it below 10A. So, more like 100W AC load max (120W DC).Is there anything stopping us from plugging a small 12v inverter into the cigarette lighter or directly to the 12v battery to power some small <1800 watt load? Would the HV battery keep the 12v charged automatically?
If you need 1,800W, you need to take it from the PCS terminals under the back seat and make sure that you don't have any significant surge loads. Also, that's like 150A DC, so make sure you use some nice fat cables.
Taking power directly from the 12V on a 3 or Y can throw errors because the car is monitoring the 12V battery charging current. On Legacy S & X you can take power directly from the battery because the car can't tell where the power is going.
