2019 Subaru Outback 12V, Amps, Wattage, and Power Invertor

I got one to be able to run my furnace if power went out. (IIRC 1500W). No it would not be run off the 12V outlet, but clamped onto the battery. Now I may be able to run something like those 60W LED’s off if the 12V outlet, but that’s what I have the 150W inverter for.
