thanks for guinea pigging yourself. Does the bolt recharge the 12V even when off or do you need to have the car running or something? I don't even know if there is an accessory mode on this thing.
having an EV "on/running" is really no big deal - since 98% of the battery load comes from the AC/induction motor - which only draws power while it's actually moving - there is virtually NO issue to leaving the car "on/running" in park with the parking brake
turn off the climate control, turn off the radio - and I'm pretty certain the Bolt would sit there almost indefinitely at the sort of electrical loads a non-moving Bolt draws…
we all have to remember 60 kWh - is a _LOT_ of power, an embarrassing amount of power actually -
"In 2015, the average annual electricity consumption for a U.S. residential utility customer was 10,812 kilowatthours (kWh), an average of 901 kWh per month. Louisiana had the highest annual electricity consumption at 15,435 kWh per residential customer, and Hawaii had the lowest at 6,166 kWh per residential customer."

60 kWh of power will run the average US household for 5 1/2 days…
the Bolt uses next to nothing if you turn off cabin heating/cooling and it isn't moving under it's own power.
with a 1,500 watt inverter with a. 10% conversion loss - can run from 60 kWh for 36 hours of continuous load. Even a fridge only used 3-4 kWh/day - cause it's not always on.
