USB Type-C has the ability to charge laptop as well

The USB 3.0 Promoter Group is looking to make the lives of mobile users a little bit easier with the finalization of the USB Type-C specifications. USB Type-C cables and connectors are aimed primarily for use in smartphones, but the organization behind the standards says that they are also “robust enough for laptops and tablets.”
The big takeaway from this announcement is that the connectors on the cable and matching receptacle allow the user to insert the cable without worrying about its orientation. This is similar in concept to Apple’s Lightning connector, but Lightning [for now] is limited to USB 2.0 speeds.
USB Type-C supports SuperSpeed USB 10 Gbps (USB 3.1) and can also deliver up to 100W of power as well. That latter spec will allow notebooks to be charged over USB, but it remains to be seen how many manufacturers will take advantage of this feature.

“USB has the luxury of consumer familiarity and trust, and as we adapt the technology for the future we are committed to ensuring the USB brand promise continues with this new USB Type-C connector and cable,” said Jeff Ravencraft, USB Implementers Forum (USB-IF) President and COO.
Now that the USB Type-C spec has been finalized, the USB-IF is now tasked with managing the spec as well as handling certification and compliance.

Okay, so with power being supplied onto the cable, what happens if the plug is put in upside down? BANG?
With the connections getting smaller and smaller it was inevitable that we'd get to a point where the plugs have to be "both way round" because the tolerances between right and wrong are getting rather fine.

No "BANG" it is just a question of being clever with the interface. My bet is that the power is only on then some control connections are hooked up and that those connection then tells the power source end which leg is to get what.

Personally I think the USB people have just been lazy for not making a connector that has no up/down as for sure the issue has been there since day 1. It is progress they have finally done something about it, only it would have been even better had they used a circular design so plugging in was even easier (most likely they did not go that way to avoid SUB and Jack connector being confused).
