I'm thinking to buy a 12v acid batttery to supply my pi 3b and my external circuit that runs 2 h-bridges (l298n) and 4 DC motors...
Can I use USB Car Charger 2 Port Adapter Cigarette Socket (plugin its + on my 12 v battery positive input and its - on my battery negative input) will it work to supply my pi 3b and its usb ports?
And Can I use 2 (One for Pi and another for another 5v output) ? I mean Duplicating the process above, using another wires and another usb car charger, Will it send 5v to both 5v output?
I know that there are many boards that make 12v to 5v...but I want to use usb car charger because it's cheap and the output is usb port!
Thanks in advance!
