USB-C is the emerging standard for charging & transferring data. Right now, it’s included in devices lượt thích the newest laptops, phones, & tablets and—given time—it’ll spread to 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 to 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 khổng lồ double the transfer tốc độ 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 và DisplayPort. Testing is even in the works khổng lồ deliver a new USB audio standard using USB-C as a potential replacement for the 3.5mm audio jack. USB-C is closely intertwined with other new standards, as well—like USB 3.1 for faster speeds & USB nguồn 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 form size of a micro USB connector. The USB-C connector itself can tư vấn various exciting new USB standard like USB 3.1 & USB power nguồn delivery (USB PD).

The standard USB connector you’re most familiar with is USB Type-A. Even as we’ve moved from USB 1 to lớn USB 2 và on khổng lồ modern USB 3 devices, that connector has stayed the same. It’s as massive 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 và thinner, those massive USB ports just didn’t fit. This gave rise lớn lots of other USB connector shapes like the “micro” và “mini” connectors.

This awkward collection of differently-shaped connectors for different-size devices is finally coming khổng lồ a close. 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 use. You’ll just need a single cable, whether you’re connecting an external hard drive to lớn your laptop or charging your smartphone from a USB charger. That one tiny connector is small enough to lớn fit into a super-thin mobile device, but also powerful enough khổng lồ connect all the peripherals you want lớn your laptop. The cable itself has USB Type-C connectors at both ends—it’s all one connector.

USB-C provides plenty lớn like. It’s reversible, so you’ll no longer have khổng lồ 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 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 tư vấn a variety of different protocols using “alternate modes,” which allows you to have adapters that can đầu ra HDMI, 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 khổng lồ connect an HDMI, VGA, larger USB Type-A connectors, và smaller USB Type-C connector via a single port. The mess of USB, HDMI, DisplayPort, VGA, & power ports on typical laptops can be streamlined into a single type of port.

USB-C, USB PD, và Power Delivery

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

Apple’s new MacBook và Google’s new Chromebook px both use their USB-C ports as their charging ports. USB-C could spell the kết thúc of all those proprietary máy tính charging cables, with everything charging via a standard USB connection. You could even charge your máy vi tính from one of those portable battery packs you charge your smartphones & other portable devices from today. You could plug your máy vi tính into an external display connected lớn a power cable, and that external display would charge your máy tính xách tay 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 lớn make sure that the devices & cables you buy tư vấn both USB-C và USB PD.

USB-C, USB 3.1, and 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, and the underlying công nghệ could just be USB 2 or USB 3.0. In fact, Nokia’s N1 game 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 khổng lồ 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 khổng lồ 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 end & a larger, older-style USB port on the other end. You can then plug your older devices directly into a USB Type-C port.

Realistically, many computers will have both USB Type-C ports and larger USB Type-A ports for the immediate future—like 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 và hubs will fill the gap.

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