As you can see above, some USB-C ports use the USB 3.2 Gen 2x2 specification, with maximum speeds of 20Gbps. The USB-IF decided on "2x2" because this standard doubles the data lanes within a USB-C cable to achieve the 20Gbps transfer speed. These ports have not been widely available. They will likely go by the wayside in favor of another emerging flavor of USB-C port, supporting USB4, which the USB-IF has announced will eventually support data speeds up to 120Gbps. If you're using a USB hub, you'll want at least a 5 Gbps connection, because all of the peripherals connected to that hub will be sharing that bandwidth. So, if you have a mouse, a keyboard and a webcam all plugged into the same hub, they will definitely need at least the 5 Gbps that USB 3.2 Gen 1 / USB 3.1 Gen 1 provides.
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? I've appeared on CBS News, in USA Today, and at many other outlets to offer analysis on breaking technology news.USB 4 has tried to avoid falling into the naming trap. There are only two versions of USB 4: USB 4, and USB 4 v2.0. Regular USB 4 has a maximum transfer rate of 40 gigabits per second, and USB v2.0 has a maximum transfer rate of 80 gigabits per second.
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. Obviously, you want USB3+ for anything data intensive. Apart from the speed, it has the added advantage that it's full duplex, so data can flow simultaneously in both directions, like on Ethernet networks or PCIe. The presence (or absence) of a USB-C port is increasingly becoming a consideration when buying a PC. If you buy an ultrathin laptop, it will almost certainly have at least one USB-C port, which will catapult you into the ecosystem automatically. If you're more of a lover of desktops, you're certain to find the ports there, too, with at least one on the motherboard-side I/O panel and likely more on high-end and gaming desktops. Some desktops and aftermarket PC cases are putting one on the front panel, too. (Desktop DIY types should know, though, that a USB-C port on a PC case's front or top will require a specific USB-C header connector at the motherboard end, and only late-model motherboards will have these.) 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. 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.USB-C’s reversibility will put an end to the classic USB upside-down jokes, but that’s not all. You’ll also be able to plug either end of a USB-C cable into the computer to connect your peripherals, provided the device also has a USB-C port. 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).
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.

Nejlevnější vs. nejdražší Redukce USB C na USB 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.

If your device (like a modern Mac) offers Thunderbolt compatibility and you don’t mind splurging a little extra on Thunderbolt-equipped accessories, you should consider investing in a Thunderbolt accessory for top-notch performance.
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. U každého produktu najdete všechny důležité informace. U některých z nich i uživatelské recenze, které vám pomohou s výběrem. USB 2.0 is USB 2.0, and anywhere you see it you can be sure that you'll have a maximum transfer speed of 480 megabits per second. Obviously, as a charge cable it’s terrible for data transfer and can’t drive Thunderbolt devices nor your monitor, but as a charging cable it’s excellent.USB-C includes support for DisplayPort Alt Mode, which allows USB-C cables to transmit video signals directly between your computer and display via the DisplayPort standard. That means your ultra-thin laptop doesn't need a chunky DisplayPort port, manufacturers can opt for a small USB-C port instead. Some USB-C cables feature a chip or e-Marker that contains information the device reads. This two meter cable’s e-Marker is incorrect.
