Samsung Galaxy S6 fast charging with Desktop Dock EDD-D200BE

Hello,

This is my first post on XDA. So I hope I my question has'nt been posted already...

I have a Samsung S6 with the original fast charger.
I still own a Desktop dock from my Samsung Galaxy S3.

Question 1 :
Can I use this desktop dock, with the original charger included with that dock, to charge my Samsung S6 ?

Question 2 :
Can I use this desktop dock, with the fast charger included with my S6, to charge my Samsung S6 ?

Thanks in advance...
