USB TYPE-C: WHAT YOU NEED TO KNOW
What Is a Type-C Connector?
Type-C simply refers to the shape and size of the connector. It
is the newest USB and is much smaller and shorter than the traditional Type-A
connector that most people still use. USB Type-C was introduced in 2014, but it
really began to take off this year. It is now in Apple laptops, Google's Pixel C tablet and Pixel phones, HTC and LG smartphones, and a handful of laptops from Dell
and HP.
What Are the Benefits of Type-C?
Type-C plugs can do the work of any other USB connector, but
they are small enough to fit into phones as well as computers. They’re about
the same size as Micro-B and just half of the height of Type-A ports. That
means electronics makers won't need to use the Micro, Mini, and other types of
USB ports anymore. Ultimately, you should be able to pack fewer cables into
your travel bag, leaving more room for snacks and cheap paperbacks. Here's
another benefit: USB Type-C plugs are reversible—there's no upside down, so
they'll work no matter how you plug them in.
Do All Type-C Devices Work the Same?
No. There's a lot of variety in how fast data can be transferred
through a USB Type-C cable and how long it takes to charge your device. Type-C
connectors will work with devices that support USB 2.0, USB 3.0, and USB 3.1,
which are standards that control the speed at which data is transferred. The
higher the number, the better the performance. With USB 3.0, the maximum
rate you can transfer data is 5 gigabits per second. The newest standard, USB
3.1, has a data rate up to twice as high, 10 gbps.
Keep in mind that the slowest device controls the speed at which data moves. So if you're plugging your new laptop into a hard drive that follows USB 2.0, the max rate is just 480 megabits per second.
Now, the truth is your files won’t move from one device to another quite as fast as the spec would suggest. So it’s best to consider these as relative numbers—USB 3.1 is up to twice as fast as USB 3.0, and up to 20 times as fast as USB 2.0.
To add a big wrinkle to this discussion, the USB Type-C ports on new MacBook Pros ouble as Thunderbolt 3 ports. They support speeds of a whopping 40 gbps, and USB Type-C and Thunderbolt 3 cables are interchangeable.
You can usually identify USB 3.x devices by the blue plastic tabs inside the ports.
Are All Type-C Connectors the Same Quality?
No. It depends on the manufacturer and whether the connectors
comply with technical standards.
Earlier this year there was a lot of buzz online about USB Type-C adapters wreaking havoc with people’s electronics. In those cases, the problem was poor product design and manufacturing, including cables that looked like USB Type-C but didn’t actually meet the standards.
A Google engineer provided a public service by reviewing lots of different cables, and he’s still a great source of updates on USB Type-C news.
Jeff Ravencraft, president and COO of USB-IF, says that sticking to well-known brands is probably a good idea, even if they cost a little more.
"If you're buying your USB cable at a convenience store from a jar near the cash register and it costs less than the bottle of Coke you're also buying, you might want to think twice," he says.
