Can I get power from my Belkin Express Dock HD (Thunderbolt 2) for my MacBook Pro Retina? I plug my MacBook Pro to my Belkin Express Dock HD via Thunderbolt, but I see that my battery is getting down. I was hopping to get power from the Dock. Is there any solution to this problem?
A Thunderbolt port can provide up to 10W. That's enough to charge a phone or a tablet but definitely not a notebook. 

A Macbook (Air/Pro) needs  between 45 and 90W.
