BlackboxMyCar PowerCell 5 LiFePO4 USB-C Dash Cam Battery Pack

So far a great product gives me peace of mind. I think the timer function is its best feature for me. I make short trips for shopping mostly and the rest of the time my car is parked in the garage. The timer function allows the camera to stay on for a set amount of time only so it doesn’t drain the battery fully, sitting in the garage. Note the USB inputs in the front of the unit are not controlled by the timer function. You need to access the rear plug for this feature.
