Just buy a A139 dashcam on 2 ch and I dont get it how Parking mode works. Mention that I try to use camera without HK3 hardware kit, the camera is connected to a usb powerbank when parked (30.000mA powerbank). I attached the settings bellow and mention that with these settings the camera records all the time, it seems not be able to enter in parking mode. From Customer support I know that the camera should be enter in parking mode in 5 minutes of 000km/h and without G sensor impact. What should I do? I want that camera start record in auto event detect mode/motion detection not recording all the time. Thanks!

I just ordered a A139 2ch as well as you and was planning to connect the same as you. How long time does it work before you have to recharge?

On a Tellur 30.000 mA (https://www.tellur.com/product/30000mah-compact-power-bank/) it works arround 20 hours at 0 C degree, and 26 hours at 15 C degrees. Its ok if you buy 2 or 3 powerbanks. My camera stay allways on powerbank (even if I drive) and when I park, the camera enter in parking mode with Auto event detection. I am very satisfied with this!
So you have to switch between these power banks? Sounds like a smart solution!
What do you think about this solution that I found on another thread

Yes, one power bank is recharging at home, the second one is in the car, tommorow will switch between. The solution from your post can be a good deal!

How safe is a Lithium Polymer battery for high temperatures in a car? I am just trying to learn. I currently own a Lithium Phosphate battery from BlackBoxMyCar called the BI-750. It is on the pricey side but I like it so far.

From what I know, the problem of Li-Po battery is when charging, not when discharging. For 4 years I use this king of batteries in my car and were no problem until now, only 3 batteries were change because of big numbers of charging cycles.
