USB-C is the emerging standard for charging và transferring data. Right now, it’s included in devices lượt thích the newest laptops, phones, and tablets and—given time—it’ll spread khổng lồ pretty much everything that currently uses the older, larger USB connector.

USB-C features a new, smaller connector shape that’s reversible so it’s easier lớn plug in. USB-C cables can carry significantly more power, so they can be used to charge larger devices like laptops. They also offer up lớn double the transfer speed of USB 3 at 10 Gbps. While connectors are not backwards compatible, the standards are, so adapters can be used with older devices.

Though the specifications for USB-C were first published in 2014, it’s really just in the last year that the giải pháp công nghệ has caught on. It’s now shaping up lớn be a real replacement for not only older USB standards, but also other standards lượt thích Thunderbolt and DisplayPort. Testing is even in the works khổng lồ deliver a new USB audio standard using USB-C as a potential replacement for the 3.5milimet audio jachồng. USB-C is closely intertwined with other new standards, as well—lượt thích USB 3.1 for faster speeds and USB Power Delivery for improved power-delivery over USB connections.


Type-C Features a New Connector Shape

USB Type-C has a new, tiny physical connector—roughly the kích cỡ of a micro USB connector. The USB-C connector itself can tư vấn various exciting new USB standard lượt thích USB 3.1 và USB power delivery (USB PD).

The standard USB connector you’re most familiar with is USB Type-A. Even as we’ve sầu moved from USB 1 to USB 2 và on to lớn modern USB 3 devices, that connector has stayed the same. It’s as massive sầu as ever, và it only plugs in one way (which is obviously never the way you try to plug it in the first time). But as devices became smaller and thinner, those massive sầu USB ports just didn’t fit. This gave rise to lots of other USB connector shapes like the “micro” and “mini” connectors.

This awkward collection of differently-shaped connectors for different-size devices is finally coming to a cthất bại. USB Type-C offers a new connector standard that’s very small. It’s about a third the kích cỡ of an old USB Type-A plug. This is a single connector standard that every device should be able to lớn use. You’ll just need a single cable, whether you’re connecting an external hard drive sầu khổng lồ your máy tính or charging your điện thoại thông minh from a USB charger. That one tiny connector is small enough lớn fit inlớn a super-thin điện thoại device, but also powerful enough khổng lồ connect all the peripherals you want to lớn your máy tính xách tay. The cable itself has USB Type-C connectors at both ends—it’s all one connector.

USB-C provides plenty khổng lồ like. It’s reversible, so you’ll no longer have sầu to flip the connector around a minimum of three times looking for the correct orientation. It’s a single USB connector shape that all devices should adopt, so you won’t have sầu to keep loads of different USB cables with different connector shapes for your various devices. And you’ll have no more massive ports taking up an unnecessary amount of room on ever-thinner devices.

USB Type-C ports can also support a variety of different protocols using “alternate modes,” which allows you lớn have adapters that can output HDXiaoMi MI, card VGA, DisplayPort, or other types of connections from that single USB port. Apple’s USB-C Digital Multiport Adapter is a good example of this, offering an adapter that allows you lớn connect an HDMI, VGA, larger USB Type-A connectors, and smaller USB Type-C connector via a single port. The mess of USB, HDMI, DisplayPort, đồ họa, & power ports on typical laptops can be streamlined inkhổng lồ a single type of port.

USB-C, USB PD, and Power Delivery

The USB PD specification is also closely intertwined with USB Type-C. Currently, a USB 2.0 connection provides up khổng lồ 2.5 watts of power—enough lớn charge your phone or tablet, but that’s about it. The USB PD specification supported by USB-C ups this power delivery khổng lồ 100 watts. It’s bi-directional, so a device can either skết thúc or receive power. And this power can be transferred at the same time the device is transmitting data across the connection. This kind of power delivery could even let you charge a laptop, which usually requires up lớn about 60 watts.

Apple’s new MacBook & Google’s new Chromebook Pixel both use their USB-C ports as their charging ports. USB-C could spell the kết thúc of all those proprietary laptop charging cables, with everything charging via a standard USB connection. You could even charge your máy tính xách tay from one of those portable battery packs you charge your smartphones và other portable devices from today. You could plug your máy tính into lớn an external display connected khổng lồ a power cable, and that external display would charge your máy tính as you used it as an external display — all via the one little USB Type-C connection.

There is one catch, though—at least at the moment. Just because a device or cable supports USB-C does necessarily mean it also supports USB PD. So, you’ll need to make sure that the devices & cables you buy tư vấn both USB-C và USB PD.

USB-C, USB 3.1, và Transfer Rates

USB 3.1 is a new USB standard. USB 3‘s theoretical bandwidth is 5 Gbps, while USB 3.1’s is 10 Gbps. That’s double the bandwidth—as fast as a first-generation Thunderbolt connector.

USB Type-C isn’t the same thing as USB 3.1, though. USB Type-C is just a connector shape, và the underlying giải pháp công nghệ could just be USB 2 or USB 3.0. In fact, Nokia’s N1 Android tablet uses a USB Type-C connector, but underneath it’s all USB 2.0—not even USB 3.0. However, these technologies are closely related. When buying devices, you’ll just need to keep your eye on the details & make sure you’re buying devices (and cables) that tư vấn USB 3.1.

Backwards Compatability

The physical USB-C connector isn’t backwards compatible, but the underlying USB standard is. You can’t plug older USB devices into a modern, tiny USB-C port, nor can you connect a USB-C connector into an older, larger USB port. But that doesn’t mean you have sầu to discard all your old peripherals. USB 3.1 is still backwards-compatible with older versions of USB, so you just need a physical adapter with a USB-C connector on one kết thúc và a larger, older-style USB port on the other end. You can then plug your older devices directly inlớn a USB Type-C port.

Realistically, many computers will have sầu both USB Type-C ports và larger USB Type-A ports for the immediate future—lượt thích Google’s Chromebook Pixel. You’ll be able to lớn slowly transition from your old devices, getting new peripherals with USB Type-C connectors. Even if you get a computer with only USB Type-C ports, lượt thích Apple’s new MacBook, adapters and hubs will fill the gap.

USB Type-C is a worthy upgrade. It’s making waves on the newer MacBooks & some thiết bị di động devices, but it’s not an Apple- or mobile-only technology. As time goes on, USB-C will appear in more and more devices of all types. USB-C may even replace the Lightning connector on Apple’s iPhones và iPads one day. Lightning doesn’t have sầu many advantages over USB Type-C besides being a proprietary standard Apple can charge licensing fees for. Imagine a day when your Android-using friends need a charge and you don’t have sầu khổng lồ give the sorrowful “Sorry, I’ve just got an iPhone charger” line!
