9V-12V from portable battery to usb hub?

I have a portable battery: http://www.xpalpower.com/us/products/xp18000/

I would like to run the output labeled DC9-12V (or DC16-20V) to a 5v/2.1a usb hub that I have.  I was thinking I could strip down a 12v usbhub car charger, but I wouldn't know how to manage the connector.  Has anyone done anything like this?

See the various instructables on building USB chargers. Basically, regulate the 9-12V down to 5V.
Was gonna say that.
