I am thinking of getting an inverter and using that to charge a computer and maybe some other things. My macbook air battery has a capacity of about 50 Watt-hours, which is roughly about 1/3 of the useable capacity of the 12 volt battery of the model 3, so it seems reasonable, but I wonder if 12 volt battery might be adversely effected or if there are other issues I may not have considered?

Also, does anyone know what the charging protocol for the 12 volt battery is in a model 3? I have seen it mentioned that Tesla used to let the charge drop to 50% and then charge the 12 volt from the traction battery. It seems unlikely that it still works that way, since 50% is too low to let a lead acid battery drop to routinely. So I would guess that there is a higher number or different protocol. Does anyone know about that?

Have people had any negative or positive experience with using the 12 volt power port to charge computers or run small refrigerators? Thanks.
