USB-C also faster charging, quicker data transfer and the ability to handle a variety of tasks, from video output to copying files. It's likely to make the jump to smartphones and tablets in the near future, as well as the next wave of laptop machines.
In short, it's safe to say you're going to be seeing more of USB-C—a lot more, given the likelihood that it may simply displace many other cables and connectors. So let's take a closer look.
Development
on USB-C began at the end of 2013, building on top of the latest USB
3.1 technology and the groundwork USB 2.0 had laid before that. From the
start, "thinner and sleeker" product designs were the aim of the USB
3.0 Promoter Group behind the standard. (The group is comprised of
representatives from HP, Intel, Microsoft, Renesas Electronics and Texas
Instruments.)
USB Type-C has the capacity to
charge up to 100 watts and 20 volts, which means USB-C can power laptops
and monitors as well as phones. That, in turn, means an end to the
chunky AC adapter bricks we're all used to. Charging happens more
quickly, and data transfer can be handled at the same time.
For
data transmission, 10Gbps is your maximum theoretical transfer rate,
double that of USB 3.0 and enough to move a high-definition movie in a
single second (until bottlenecks such as your hard drive come into play,
at least). The underlying technology isn't an upgrade in the same way
that USB 2.0 to USB 3.0 was—it's the physical connector that's the main
difference.
By the way, don't be confused about a
second USB update, the move from the USB 3.0 standard to USB 3.1. Think
of it this way: USB 3.1 sets the protocols and internal technology
standards for computers and phones that make 10Gbps data and 100-watt
charging possible; the USB-C plug is effectively the "launch device" for
that faster, more powerful technology. USB 3.1 has been around
since July 2013, but both it and USB-C will be new to consumer devices.
It's
worth noting, though, that it's possible for cable makers or hardware
vendors to configure USB-C cables for USB 2.0 or USB 3.0 connections.
Most USB-C cables should be USB 3.1 ready, but it's worth looking out
for in specs lists.
The 8.4mm by 2.6mm 18-pin
connector can be used both ways up, as we've already mentioned, and
there's a quoted lifespan of 10,000 cycles (the same as microUSB).
Identical connectors are used at both ends of the cable, so not only is
there no danger of getting it upside down, you won't get it the wrong
way around, either.
Like Apple's Lightning
connector, USB-C cables contain embedded circuitry that let them work
out which way around they are and what's required of them (power, data
or video). Previous versions of USB only used "dumb" cables with no such
integrated intelligence.
Plenty of
future-proofing has gone into the new USB Type-C standard, so we should
be using these types of ports and connectors for many more years to
come. Like earlier versions of USB, it's an open standard, so won't be
restricted to one company or manufacturer.
A
thinner, more efficient USB standard means thinner and lighter laptops,
as well as smartphones that charge more quickly. As always, it will
take time for manufacturers to move over to the new standard, and you
might have to put up with an awkward adapter or two—or the odd hybrid device—while the transition is underway.
As
the new MacBook and the 2015 Chromebook Pixel prove, USB-C means fewer
ports on your computer. That in turn gives rise to more compact hardware
designs and fewer cables.
The distinction
between large capacity, mains-powered external hard drives and lower
capacity, USB-powered ones is going to disappear. Vendors now have the
opportunity to make bus-powered "portable" external hard drives of much
larger capacities, because USB-C can offer enough power to keep them
running smoothly.
And that power can flow both
ways—a peripheral device could charge a host device in certain
circumstances (e.g., you could use a tablet or a battery pack
to power your laptop). We'll get more flexibility when hooking up our
various bits of hardware, and will have to stuff fewer cables away in a
drawer somewhere.
Same with data and video.
Something playing on your smartphone could show up on your laptop
screen, or vice versa. A few years from now, you might well be using one
cable to charge your laptop, tablet and smartphone—and to fling video or photos at on your big-screen television.
USB
Type-C is going to make cables more versatile and standardized, our
mobile devices smaller and able to charge more quickly, and that's just
the start. In a few short years you may wonder how you ever did without
it.
