Since 3dCadWurx has no control over the source of the switched 12v power supply, the condition of the vehicle wiring, and what else has been added to the circuit that also may present a current draw, it is the vehicle owners responsibility to ensure the power source and wiring can handle the electrical load of ~4A per charging module, which would in theory be the same current draw as a USB power adapter plugged into the cigarette lighter socket.
Just bought this for my 2013 Audi S5. Do you have a suggestion on which switched power cable to use?
