Type-C to Type-B 3.0 adapter
A USB Type-C plug on one end and a 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
- Rounded oval about 8.4 mm wide, symmetrical top to bottom.
- Reversible: there is no wrong way up.
- A flat tongue with contacts on both faces sits inside the socket.
- 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
USB Type-B (SuperSpeed) — socket
Type-B with an extra storey stacked on top, almost always blue.
How to recognise it
- Looks like a Type-B that has grown a second chamber above it.
- Nearly always moulded in blue plastic.
- A plain Type-B plug will fit this socket; this plug will not fit a plain Type-B.
- Maximum speed:
- 5 Gbps
- Maximum power:
- 4.5 W standard
