However, the most recent USB 4.0 spec can reach up to 40Gbps and is only available in USB-C form. USB-A vs. USB-C: Which is better? For charging speeds we recorded the maximum wattage at which the cable could charge an Asus ROG Strix 15 gaming laptop over its USB-C port using USB-Power Delivery with an Aukey 100 watt USB-PD charger as the source while the laptop was under load.USB-PD today is limited to 100 watts (with a 240-watt spec on the way). Any USB-C to USB-C cable should handle 3 ampsat 20 volts, or 60 watts.All of the USB-C to USB-C cables fell into the standard 60-watt or 100-watt camps. BTW, 10Gbps USB3 introduces a new channel encoding which is more efficient. So while the 5Gbps variant translates to at most ~450MB/s real data (after accounting for channel encoding and protocol overhead), with 10Gbps you get ~1100MB/s. Consequently, Gen1x2 is slower (2x450 = 900MB/s) than Gen2x1 (1100MB/s). But it might work over longer distances.

Landing on a single standard to rule them all is an elusive aim in the realm of personal technology. At best, you end up in a format war, and one faction emerges victorious for a few years until an entirely new technology takes it out. VHS ate Betamax, then was ousted by DVD, which faded in the face of Blu-ray, itself now virtually extinct following the rise of online streaming services.

USB 3.1: THE NEXT EVOLUTION

USB 3.0 can achieve transmission speeds of up to 5 Gigabits per second (or 5 Gbps), whereas USB 3.1 can achieve up to 10 Gbps. However, USB 3.2 has two 10Gbps lanes and is thus capable of achieving 20Gpbs. In 2013, USB-IF announced that it was taking USB up to 10 Gbps and, in doing so, changed the version number for all USB 3.x products. So USB 3.0 (5 Gbps) became USB 3.1 Gen 1 and the new, 10 Gbps speed became USB 3.1 Gen 2. We then looked at how fast the cable would charge and transfer data, and whether it supported an alternate mode to run a monitor, using real-world hardware. pixelpusher220 said:At least for me this was helpful. Basically all that's important is the Gen 1/2 for the Type A, and only Gen2x2 for the zippy zippy.

You’d think you could tell whether a cable is USB-C 2.0 cable by looking at the wires in the connector but that’s not the case. Some cables use connectors with pins that aren’t hooked up to anything. Put simply, the more advanced versions of the USB protocol allow for faster data and power transfer. Most of us will never care enough to tell the difference between USB 3.0 and USB 3.2, but it's nice to know how it all works. Chris Hoffman is the former Editor-in-Chief of How-To Geek. Chris has personally written over 2,000 articles that have been read more than one billion times---and that's just here at How-To Geek. We didn’t test the temperature of each cable’s housing, but we did test the cheapest cable by running it at 5 amps and 20 volts for an hour. The housing heated up by 50 degrees Fahrenheit, and the cable itself became relatively warm (see the thermal image below). Not ideal, but it did this without failure. We subjected other cables to two-hour loads without failure, as well.Even though Thunderbolt offered better performance, it didn’t see a lot of traction because of its high price. Both USB-A and USB-C ports can support USB 2.0 to 3.2, which makes the whole thing a bit confusing since a USB port has both a connector type (USB-C vs. USB-A, or rounded vs. rectangular) and a USB specification which reveals how capable it is.

USB-C is an industry-standard connector for transmitting both data and power on a single cable. The USB-C connector was developed by the USB Implementers Forum (USB-IF), the group of companies that has developed, certified, and shepherded the USB standard over the years. The USB-IF counts more than 700 companies in its membership, among them Apple, Dell, HP, Intel, Microsoft, and Samsung. Hledáte nejlepší Redukce USB C na USB?

Nejlevnější vs. nejdražší Redukce USB C na USB Before I joined the tech-journalism ranks, I wrote on topics as diverse as Borneo's rain forests, Middle Eastern airlines, and Big Data's role in presidential elections. A graduate of Middlebury College, I also have a master's degree in journalism and French Studies from New York University. The 20 Gbps speed is called USB 3.2 Gen 2x2, because it uses two 10 Gbps lanes to give you the 20 Gbps speed. Would it have been less confusing if they called it USB 3.2 Gen 3? Who knows? However, despite the USB-IF's desires, we still see most PC vendors listing their ports as USB 3.2 or USB 3.1, without necessarily telling you what to expect from them. The spec sheets may not even list a generation number, though if they don't, you should assume that it's Gen 1 (5 Gbps).

REVERSIBLE C-CONNECTOR

Confused yet? Further complicating matters: The number scheme around USB 3 has been in flux, which has made references to these ports something of a swamp. Until recently, many USB-C ports carried the USB 3.1 label ("USB 3.2" was not yet a thing) in Gen 1 and Gen 2 flavors, and some spec sheets continue to reference the older name, along with SuperSpeed branding. In a confusing twist, the USB-IF decided to eliminate the use of "USB 3.1" in favor of these various flavors of USB 3.2, as outlined below in this handy decoder chart... USB Type-C connectors have been around for a while now and are found on modern Android devices, headphones, and gaming consoles. They’re pretty much the same size as a micro USB connector that you see on mobile devices. How is USB Type-C Better? Finally, and perhaps most importantly, external SSDs and the best hard drives need at least USB 3.2 / 3.1 / 3.0 speeds. The fastest external SSDs or SSD enclosures can operate at USB 3.2 Gen 2 (10 Gbps) or USB 3.2 Gen 2x2 (20 Gbps), though the 10 Gbps speed is far more common and cheaper.

USB-C (or USB Type-C) is slowly becoming the standard port for consumer devices. Almost every new laptop, tablet or phone has USB-C connectivity. This is because the connection type fixes many of the problems associated with USB-A. It also has many features that surpass its predecessor.

You might think of your old USB Type-A port simply as a data port for connecting drives or peripherals like mice. But USB-C, depending on the specific port's implementation, can do much more. One of USB-C's most useful skills, when designed thus, is delivering enough power to charge the host device, such as a laptop or a smartphone. In fact, many lightweight laptops that have USB-C ports use them in place of a traditional barrel-style connector as the only option for attaching an AC adapter. Starting in 2015, Chris attended the Computer Electronics Show (CES) in Las Vegas for five years running. At CES 2018, he broke the news about Kodak's "KashMiner" Bitcoin mining scheme with a viral tweet. A wave of negative publicity ensued, with coverage on BuzzFeed News, CNBC, the BBC, and TechCrunch. The company's project was later reportedly shut down by the U.S. Securities and Exchange Commission. The Anker Powerline II has a power output of 100W. This feature makes it apt for charging your MacBook Pro, tablet, or your phone with ease. In the end though, it’s what’s inside a cable that matters the most and the Apple USB-C cable has top-notch wiring materials that can deliver the most power to your laptop, phone, or tablet. Want to charge your laptop at 100 watts all day? That shouldn’t be a problem for the Apple USB-C Charge Cable. To reduce confusion, the USB-IF also intends to do away with numbered USB versions in the future, instead encouraging device makers to refer to a port's top speed, as in "USB 20Gbps." We're in favor of that.
