How much battery do I need to run a phone camera in my car? (lemmy.world)

I was thinking of buying an unlimited data plan and using an old phone to record around my car through an app.

Problem is the power source, how big of a battery do I need to keep in my car?

Like.. can I just use one of the regular travel chargers and like switch it out wit another daily or? Would it last a day?

Like how big does it have to be for a week then?

lets say you got a mediocore fon containing a 4Ah battery, which will last 12h when constantly recording (estimated, correct it if I am wrong). A 20Ah powerbank will run the device for app. 2.5-3 days. Two power banks around 5 days. Charge powerbank from the usb port or a usb cigarette lighter adapter. Usually cigarette lighters get switched off when you turn off the car to prevent the 12V battery from discharge
