I wonder, did anyone succeed in powering the parking mode with a pass-through powerbank? And what capacity do you need for, say 10 hours parking mode?
Someone else on this forum says that this camera draws ~3 watts in parking mode and assuming around 12V
Going off of the example formula found here:
https://answers.yahoo.com/question/index?qid=20130505122001AAXfO7u
40Watts / 12 V = 3.33A= 3333mA
5000mAh / 3333mA= 1.5hours or 1 hours 30 minutes
Converting this to a useful formula:
x mAh / (y Watts / z V) = h hours
h hours = x mAh / (3 Watts / 12 V)
> h hours = x mAh / (1/4 Watts / V)
> h hours = x mAh / (1/4 A)
> h hours = x mAh / (250 mA)
>> x mAh = h hours * (250 mA)
For 10 hours:
x mAh = 10 hours * 250 mA = 2500 mAh
I recently bought a 20100mAh battery, I'm curious to know how many hours to expect:
Using Formula: > h hours = x mAh / 250 mA
h hours = 20100mAh / 250 mA = 80.4 hours
(Probably want to factor in ~15% less actual time due to real-world conditions)
I'm going to try a pass-through bank to get a little bit of charging while I drive, and add a USB switch to only turn on camera (use the battery bank) when I really need it while parked without having to unplug cables. I'll try to remember to post the results.
