This is a passthru single port version of what I built, well…other than using the power provided by the port of course…mine uses an external power source
Truthfully you could take a standard USB cord, open it up around 1/2 way down, short the D+ and D- cords together and the device will pull up to a max of 1A then heatshrink it closed again…a “5 watt dedicated charge cable”
