2017 Cmax Energj

I have a new dashcam that included a USB C power kit so it's always on, even when parked / car turned off.

I'm curious as to how I should wire this to ensure I don't drain the (small) starter battery.. Does this battery get topped up from the larger battery bank? Is it viable to connect the USB c directly to the cells in the trunk vs the traditional methods?
