USB Extensions

I have a dumb question.  When you have a USB port that is rated at 2.1 Amps.  Then you stick a 2-port USB into it.  What power does the 2 extension USB ports have?  Both at 2.1A?

I'm trying to figure out a USB port in a car that is rated at 5V 2.1A.  I want to add a 2-port USB extension to it so I can have 2 USB ports instead of just the one.  I'm trying to find out if I still get 2.1A from both extension USB ports?
