What USB cable do I need?
Sixteen connectors, photographed from the same angle at the same scale. Find the one in your hand, then find the cable that fits it.
All USB connectors
Shown plug-first, looking straight at the face - the view you get holding one up. Tap any connector for how to recognise it, what it plugs into and what it can carry.

The flat rectangle everyone pictures when they hear “USB”.

The small trapezoid that charged every phone before Type-C.
Still around -

What cable do I need?
Pick the connector at each end. Not sure whether an end is a plug or a socket? A plug is the bit you push in; a socket is the hole it goes into.
Why two identical USB-C cables behave differently
Every connector on this page can be identified by looking at it - except one. A USB-C plug that carries 480 Mbps and 15 W is physically identical to one carrying 80 Gbps and 240 W. Nothing on the outside tells you which you are holding.
