Review: Works As Described With One Exception - Instead of shutting off after five minutes, it actually shuts off after about twenty minutes. That's not an issue, just noting the difference. I assume this device is measuring battery voltage to determine when the car is off or running. Charging voltage on a car battery is around 13.5 to 14v (when engine is running). When the car is turned off, the battery is no longer being charged and voltage is just the battery alone @ 12V. I think that's how it works. ## Features - Designed to free up your cigarette lighter socket and supply a 24 hours continuous power to your dash camera via OBD connection, enable your dashcam to keep working on after you have parked the car. - Dual working mode switch button integrated for your convenience: 1.ACC working mode,5 minutes off when your car ACC is off; 2.
