How to add a second wire to car battery?

[ShiWarrior]

At what low vehicle battery voltage does it stop charging the neo ? (how much does it leave for the vehicle) seems like it is 11.7V

expensive piece of kit though, can you accomplish the same with https://www.amazon.com/Yukuma-Power-Bank-Engineered-Certified/dp/B073PN843G or similar ?

Not sure how long it would last if its in constant use for parking mode
and could you link this to a thinkware ? (its not usb or micro usb
Could you install it in the car and forget about it like the cellink ? i wouldn't want to remove it i want to hide it away and forget

yes that power bank does not have very good reviews too.

An alternative 'budget' solution might be a usb - pd power bank
https://www.amazon.co.uk/gp/product/B071JWNQ8Y 20000maH and a pd car charger https://www.amazon.co.uk/gp/product/B075R8Q1FY
but has 2x the charge time.

4 hours to charge is way to long for me, also again , thinkware is not any usb, the connector is a round type

yes, ok, it's not usb, but cellink is £250, this has 2x capacity and would charge to same capacity as cellink in 2hrs, versus its 1hr10.

cellink will charge in 45 mins from flat which is why i opted for the more expensive model and should last 38 hours for a 2-channel camera setup
