Type-C offers charge rates up to 100W, which means the voltage is ramped to 20V.

There is an entire protocol to negotiate power delivery (including who charges who) http://www.usb.org/developers/powerdelivery/

And the latter part have caught some people unaware, where a battery pack and a phone will ping pong who is charging who until both are dead.

Or, if you're really unlucky, it'll attempt to charge your wall. No, I'm not joking: https://twitter.com/chimeracoder/status/941820122406064128

My phone has offered that option when I plug into the car. While the car could in theory benefit from the charge (it's a plug-in hybrid), I doubt the phone would be able to provide much of value.

Sounds like a good way to steal power from work -- charge up your phone at the office and supply power to your wall outlet when you come home.

Ok, that's it. Murphy does not need to verified any more. And i need a really really stiff drink.

That is hilarious. At least it gives you the option.

Gotcha, I was wondering if the VBUS was dynamic. Thanks for clearing that up for me and linking to the documentation, I appreciate that.
