I’ve been known to carry a cable or six whilst working out of my bag. This Bestfon 3-in-1 Dual Retractable Cable would tidy things up a bit though. It has a 2m retractable RJ45 Ethernet cable with two plugs on one side and a 1.5m male USB A to male mini USB B type on the other. Bestfon make a whole range of different types of these as well, including FireWire and RCA plugs.
