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.

## Questions & Answers

**Q: Will this fit a lexus ct200h?**
A: OBD II (OBD 2) is a standard plug type that is may be also called a diagnostic port. Almost every car has had one for the past 20 years. Check your manual.

**Q: Can two dash cam be hook up to this Front and rear ?**
A: Generally the rear camera plugs into the main camera unit and power is provided to the main camera unit--so yes, this should power a standard 2 camera setup.

**Q: Do you sell a similar power cable with a micro usb connector? can it be longer than 11.5 feet?   i really like the dual working mode feature.**
A: Hi,so far we sell mini usb connector only in US .But the cable and connector can be customized if we send it from China.

**Q: Does this OBD power cable work with 70mai dash cam lite?**
A: I would say yes. I have tested this unit on over 20 different dash cams, and it worked flawlessly with all of them. In my line of work, I recommend and install dash and surveillance cameras. In all of the dash cams, I suggest that they purchase this unit
