- Capable of delivering data and power with direction being negotiated (a dock could power a laptop, or a laptop power a dock).
- Power up to 100W – devices start at 5V but can negotiate up to 12 or 20V at 5A. The Chromebook Pixel’s supply is 12V 3A (60W), and because this is now standardized, it should be able to power any device (including the new Macbook) … well, in theory.
- Devices can negotiate to repurpose half the data lines as an “Alternate Mode”, with a native DisplayPort video channel defined by VESA being on of the first Alternate Modes defined. The Chromebook Pixel appears to support this, which is how it implements its USB-C to HDMI adapter.
- The USB-C port is very small, thin, but strong. Pins are mirrored on either side of the port and hardware detects and corrects for orientation, so devices can be plugged in either way and work the same.
Dozens of companies and of course Intel were involved with the definition of USB-C. But the surprise here is Apple. Historically, they’ve intentionally created proprietary connectors or re-purposed standards in non-standard ways. But with USB-C, we’re seeing a serious Good Guy Apple moment. They contributed significantly to the USB-C connector, from supporting either orientation (like the proprietary Lightning connector) to making sure USB-C could be a functional superset of every bus that’s gone before. It’s a huge credit to Apple that they saw the potential for a single bus that could be standard across every device – Mac, iOS, Windows, Android, whatever.
Enough talking. Let’s see it in action.
