Type-C USB

[Master of None]

"The new Type-C USB also supports up to 100w power delivery and is capable of up to 10Gbps transfer speeds."

Assuming it runs at the regular 5V dc, how can such a small connector handle 20A.

The 100W power is 5A at 20 volts. Several other voltages are supported.

Bad assumption. My understanding is that the "100W" is 5A at 20V.

Thanks guys, should have looked myself.
I wonder how the cheap import chargers on the horizon will play out with the extra complexity?

Without getting involved with the more complicated Power Delivery protocols, the cable can still provide 3A at 5V (from a suitable source) with very simple (resistive) signalling, so cheap chargers still remain feasible.
