Dual Car Charging Thru Micro Adapter & Hub?

the belkin adapter outputs a full amp, which if you use the targus mini hub without it's power supply, will be divided by 4 (250mA per port)

You are correct I guess. With the hub in the line and a Motorola H700 bluetooth on it the Droid battery icon shows no indication of charging.
 
The hub is most likely telling the Droid that it can't source the power it is requesting so the Droid doesn't even try. As I recall, USB ports must supply 100ma, but may supply 500ma (or more), it's all controlled by software. A dumb power supply can signal a device that it can supply >500ma but shorting the D+/D- pins on the USB connector.
