In Part 1 of this story, we looked at the history of USB, the reasons that Type-C came into being, and the standards that make it what it is. In Part 2, we'll talk about the added advantages of Type-C, and the practical effects it will have on our lives right now and in the long term.
Additional features and benefits
Beyond the potential bump up to 10Gbps speeds, Type-C allows for a whole raft of other features. The most important of these is the updated Power Delivery spec which allows devices to negotiate for up to 100W of power - ten times more than the 10W USB 3.0 was designed for. For desktop peripherals such as printers, this means separate power bricks could be dispensed with, and smaller devices will be able to charge a whole lot faster than they do now.
A single cable between a laptop or phone and a docking station could let the portable device send audio and video output and connect to networks and accessories such as hard drives and printers, while also receiving power. Multiple devices could be consolidated into one, reducing cable clutter. For example, Apple's Thunderbolt Display already lets MacBook users do this with two cables - a possible future version with Type-C could reduce this to one. Eventually all kinds of desktop accessories could route power to our portable devices, and ports or card readers that can't fit on devices themselves could be accommodated on the chargers we always carry around anyway.
Specific cables will be required for anything more than the basic 10W power level, for safety reasons. There are also larger implications, such as being able to run USB wiring around a house to eliminate the need for "wall-wart" adapters for charging small devices, but this is still a long way away.
