I was curious to measure the current draw for the P2 in a hot vehicle since heat can be a worse case environment.
I measured the current using a USB-C Tester with the P2 setup with all four channels (front, rear, cabin, thermal). The SD card is 128 MB, normal driving mode with highest resolution settings.
According to the P2 User manual, it's Power Supply (CLA, Cig. lighter adapter) specification is 5V 3A but I was supplied with a 5V 2.5A VP05 (II) Hardwire Kit rather than the newer VP05 (II) rated for 2800 mA.
The Hardwire kit is used when the user wants to implement parking mode, whereas the CLA does not support parking mode.
P2 User Manual for the CLA adapter:
I found a reference on Vantrue's website that indicated the operating current for the P2 is up to 2850 mA which is greater than the VP05 (II) is specified to provide:
Looks like a typo in the website where it says 2850mA/h
The inside vehicle temperature was 101.5 °F (38.6 °C)
I measured a peak current of 2.25 A
The current fluctuated but the average was closer to 2.0 A
Based on these measurements it appears the VP05 (II) should work but the operating requirements of the P2 (for current) do not line up with the output specification of the VP05 (II).
I've been waiting for some poor visibility conditions to test the thermal camera but the weather in the North East has been more like sunny CA.
