Tesla should introduce an optional 1500W inverter that can be used during an emergency power outage. Just have a plug in the frunk. The Tesla app could keep you updated on how long your backup power will last based on current load. A typical refrigerator draws about 150W which a 75kWh battery could supply for over two weeks assuming it never cycles off. Even a full load of 1500W would last over two days. This seems like such an easy feature to add to the car that could be extremely useful in many situations.
