(Apple’s new MacBook)

Apple’s new MacBook is turning a lot of heads, thanks to its superslim design and reimagined keyboard. But the real story, for Mac and PC owners alike, is the inclusion of a new kind of USB port, USB Type-C.

OK, it might not be the sexiest topic –– USB C could use a rebranding, for sure –– but hear me out. This humble port, which you can already try out on Google’s recently released Chromebook Pixel, is going to change the way we use everything from smartphones and tablets to laptops and desktop computers.

You know that rat’s nest of tangled wires you keep bundled in your bag or your desk drawer? A single USB C cable could replace all of them.

Yeah: One cable to rule them all.

Now you’re interested, right? Here’s how it works.

A new kind of standard

You use USB ports every day. Whether it’s connecting your mouse to your desktop or charging your smartphone, USB is everywhere.

The most common form is the USB Type-A standard, the large-size connector on the side of your laptop or desktop. Then there’s the microUSB Type-B standard, which is what you find on most smartphones and tablets. And while those are convenient, they could certainly be faster, smaller, and easier to use.

USB Type-C, or just Type-C, is a new standard that’s completely different from the cables and connectors you’ve previously used.

According to the USB Implementers Forum, the group in charge of setting USB standards, Type-C can not only transfer small amounts of data and charge phones and tablets like current USB standards do, Type-C can also be used to charge something as large as a laptop and even stream video.

It can also transfer huge amounts of data at a mind-blowing 10 gigabits per second; that’s twice as fast as the older USB 3.0 standard on your laptop or the microUSB your smartphone uses.

That’s why Apple is able to use Type-C as the only connector on its new MacBook: It can do everything all of those older ports on your current computer can do. And it’s really small, too: about as thin as a standard microUSB connector.

Charging ahead

But it’s Type-C’s ability to charge a wide array of devices that is truly impressive.

While most smartphones and tablets use microUSB connectors for charging and transferring data, the iPhone and iPad use Apple’s specially made Lightning connector.

Laptops, however, use a wide variety of chargers. That means, if you’re going on a business trip, you need to bring a charger for your phone and tablet and another for your laptop.

Type-C, however, has been designed so that it can power smartphones, tablets, and laptops. That means if you buy a laptop that is USB C compatible, you’ll need just one charger for all of your devices.



Techies out there might be wondering how a charger designed for a laptop can also charge a smartphone without blowing out its battery. The answer is that your phone, or any other Type-C device, can talk to the charger to determine how much power it needs. The charger then sends the correct amount of power to the device without damaging it.

You’ll even be able to charge your MacBook using the charger that comes with your smartphone, albeit at a much slower rate.

That’s an incredible benefit to both companies and consumers. Companies win out by having a single charger and cable for all of their devices, cutting down on packaging and materials. Consumers win by only having to carry a single charger for everything. And if you lose your laptop charger, you can just go to the store to pick up a new one, rather than having to get one sent to you by the manufacturer or taking your chances on some third-party charger.
