Gold plated usb contacts and upgraded usb male female connector.
Widened power cord make it own 5a high current.
If you set the current accurately to 500 ma you can calculate the wire resistance.
Making your own cables is a particularly difficult endeavour with usb if you wish to have reliable usb 2 0 or above speeds on the data lines because the cable s characteristics in terms of twists meter impedance and capacitance meter as well as screening shielding need to be controlled to tight tolerances to ensure noise doesn t get in.
