I'm going to install a new USB / Power outlet in my vehicle.
It consists of two USB A sockets rated at 2.2Amps each AND one standard size "Cigarette Lighter" socket (amp rating unknown)
To power this, I intend to run positive and negative wires directly from the vehicle battery (fused of course) to this new USB panel.
The total distance is approximately 7 feet.
What I'm wondering is what is the MINIMUM gauge of stranded copper primary wire I can safely use for this?
I have 16ga primary wire on hand but I'm concerned this may not be sufficient. Surely 14ga would be adequate?
Thanks
