Type-C to Micro-B 3.0 adapter
A USB Type-C plug on one end and a Micro-USB Type-B (SuperSpeed) socket on the other. This converts a port rather than carrying a signal any distance, so it is usually a stubby dongle rather than a cable.
USB Type-C — plug
The small oval that goes in either way up - and hides the most variation.
How to recognise it

- Maximum speed:
- 480 Mbps to 80 Gbps, depending entirely on the cable
- Maximum power:
- Up to 240 W with USB PD 3.1 and an e-marked cable
Micro-USB Type-B (SuperSpeed) — socket
A Micro-B with a second block bolted alongside it. Portable drives, mostly.
How to recognise it

- Roughly twice as wide as a plain Micro-B.
- A plain Micro-B plug fits the left half of this socket and works at USB 2.0 speed.
- Maximum speed:
- 5 Gbps

- 4.5 W standard
