Loose tests on mine have the front USB turning off shortly after the car is off and my back USB lasts around 90 minutes. My dash cam is plugged into the back USB and I've checked it's behavior frequently. The front USB is not something I've tested more than once.Thanks. I'll need to check my Maverick to see how long that port stays active. If it's only a short while, then it will not be as handy I initially thought.
