Reviewing and Testing the new Vantrue E360 Ace Dashcam

Things became interesting when the E360 was used without the GPS unit attached. Like the first time, I started with +12v on both the red and yellow wires. I found no difference in voltages on the USB-C pins as a result of connecting/disconnecting the +12v yellow ACC wire, suggesting that drive/parking mode switching is controlled entirely within the GPS unit:

Yep, I get the distinction, I was just curious to see how things would play out. With the E360 camera plugged into my Ecoflow power station as well as my DIY LTO battery pack, I'm seeing fluctuating power draw, so I was making a series of more careful measurements to see if I can get any insight on what is going on. The camera functions well, I'm just wondering why my external batteries report fluctuating power.
 
I just realized that I never posted any power consumption data for the E360 camera. I made a few measurements with my bench top power supply connected to the Vantrue hardwire kit and driving the E360 with the GPS unit attached and the rear camera connected (3-ch mode).

In drive mode with the screen on, I'm measuring an average of 6.76w of power consumption. Minor fluctuations seem to range from 6.32w to 6.92w. So, let's round up just a little and call it a maximum of 7w of power draw.

On the opposite side of the spectrum, with the E360 in 3-ch LBR parking mode and the screen turned off, I'm measuring an average of 4.68w of power consumption. Minor fluctuations seem to range from 4.27w to 4.88w, so with a little bit of rounding, we can call this a maximum of 5w of power draw.

These measurements INCLUDE the power consumption of the hard wire kit in addition to three channels of recording.

Just adding some additional data: The 128GB card that Vantrue sent to me along with the E360 camera holds about 18 hours worth of low bit rate parking mode videos from its three cameras before the camera starts overwriting files on the card.
 
I just posted to measurements of the behavior of the VP03 (II) and VP05 (II) hardwire kits to my thread on the N5S camera. The power efficiencies are pretty good and the user-selectable voltage shut-down levels are EXTREMELY precise.

I also made some measurements of the Vantrue hardwire kits to look at both the accuracy of their battery protection voltage settings and their overall power draw while in drive mode and in parking mode. I tend to think that power draw while in drive mode (with both Red and Yellow wires receiving 12v from the car's electrical system) is mostly irrelevant because the engine is running, so the car's electrical system is energized and charging. Power draw in parking mode (only the Red wire is receiving 12v from the car's electrical system) is much more relevant, since you are drawing battery...
