Yes, I use microusb charge cables with 20 AWG power wires
to reduce I2R losses. This is the same concept behind those thick battery cables on our vehicles.
I definitely recommend 20 AWG if you're planning to have a longer cable (either in the vehicle or at home).
However, the charger's power rating per port is a much more important consideration. The 20 AWG charging cables just let you maximize the draw.
