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?
I have to assume you don’t have charging ports on your car to just have the phone plugged in the whole time? Does it have a cigarette lighter? You could get a charger that plugs in there.
