Building
One easy way to build such a cable is to use any USB A cable and with a DB9 femelle connector. It doesn't matter if the cable is charge-only, USB 1.0 or USB 2.0 etc.
Build the cable with the following connexions:

With this cable you will be able to power your quack converter with any USB charger available.
