So I came home to a power outage last night, ah mountain living.

As I am burning the lamp oil for light, and hating the fumes I start to wonder why I'm sitting in the dark with 40 kWh in the battery sitting in my driveway. I decided to plug a small inverter into my cigarette lighter in my Model 3 and power some lights in the house with it. Since its just a 200W inverter I wasn't too worried about draw, but I was aware that it would drain my 12v battery.

Anyone know how often the main HV battery charges the 12v battery? Also, how many amps is the dc-dc converter able to provide safely to the 12V battery?

If this power outage lasts longer I might get crazy and pick up a 1000w inverter and seeing if it will power my refrigerator. I just want to make sure I wont be running down my 12v battery too badly.

If I do run down my 12v battery, what would be the effect? Would the car still be drive able? I guess the 12v systems like lights, windows ect wouldn't function, but I am not sure. Anyone with experience?
