Review: Works great for my needs - This product is working great for my needs. I just needed my dash cam to run while my vehicle is on otherwise the camera will drain my battery. It was easy to install and has been working great for me specific needs. I would say this is much easier than other options out there or trusting a dash cam to shut off on its own.
Review: Works as advertised - Works well with my dashcam. Makes supplying power easy and clean. I hate tapping into the fusebox. It's actually a bit dangerous because the taps can get loose over time. This taps into the OBD II port for power. Just plug it in. If you need the OBD port for something, just unplug this until you are good to go. No hassle.

## 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

### ⭐⭐⭐⭐⭐ Solved - random auto shut-off on highway
*by A***E on July 7, 2020*

I'm very pleased with this product and I'm writing a review in case anyone has the same issue. (I drive a 2014 Honda Accord.) I leave this product set in the position that turns off after 5 minutes when the car is off (not the always-on position). I started noticing that my dash cam would randomly turn off on long car rides on the highway. I thought this power cable was faulty and I could get the camera to turn back on by flipping the rocker switch to always-on and back again. But after some more time in the car, I was able to isolate the problem better. When my car is running at a constant highway speed on cruise control for a long time, the OBD voltage drops and the camera turns off. All I have to do is slow down my cruising speed by about 5 mph, and then the dash cam will come right back on - then I can resume my original speed. This might be a function of the OBD protocol at constant speeds, or it may be a gas-saving feature of the car - reducing alternator load (and voltage output) when it's not required. Luckily my dash cam makes an audible tone when turning off, so I know when to adjust my speed and turn it back on. I never seem to have this issue during city driving.
