While the 110-volt outlet in the 2023 Prime might be useful when the car is stopped, it could also be useful when the car is driving. Eg. my sister needed an electrically-powered oxygen concentrator, and she had a big battery pack to run it when in the car. Presumably she would have been able to plug it in the Prime's outlet and use it for trips without its battery. But my question is: Does the 110-volt outlet have power if the traction battery is showing empty? Is this why you might want be charging the Prime battery while driving? In other words, if the Prime were running on EV alone, my sister had the concentrator plugged in, and then the traction battery ran out of juice and the car switched to internal combustion, would that 110-volt outlet still have power?
