Review: No More Wires Running Everywhere! - If you're tired of dash cam cables snaking across your interior, this is the perfect solution. Designed to free up your cigarette lighter socket. Integrated dual-mode switch: • ACC Mode: Powers off 5 minutes after your car’s ACC is turned off. • Surveillance Mode: Keeps running until it detects low battery voltage (11.6V), protecting your car’s battery. It draws power solely from the OBD interface, so there’s no interference with other OBD data communication. Easy install, smart features, and no clutter—this cable makes powering your dash cam a breeze.
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.
