Switching to USB-C is inevitable: most current smartphones, though they do not come from Apple, now support the new take of connection. Even with many modern laptops, USB-C is often the only option for connecting other devices.
But what can actually do USB-C? Is the new connection automatically faster and better? We explain the subtleties
This is USB-C
First, the term "USB-C" describes the physical specifications for a port. USB-C must terminate the previous USB clutter. For example, the standard USB-A port is too big for mobile devices. So, most of the time, the microUSB variant has been used here.

USB-C, on the other hand, is small and robust at the same time, so it can be used for large devices such as monitors or laptops. The USB-C is also symmetrical. Unlike the microUSB, you do not need to turn the cable three times before connecting it until it is in place, but you can plug it in easily.
What the USB-C can do in practice depends on the devices used. Data, audio and video signals can be sent via USB-C, as well as can be used for power. But the connected device must of course support a corresponding function.
What is the USB-C for?
In addition to the physical connection, of course, you also need a transmission protocol. Along with USB-C USB 3.1 has been developed here, but it is not compatible with that. In this way, USB 3.1 connections can be established with the old USB-A ports if the devices used support it.
USB 3.1 supports data transfer at a rate of up to 10 gigabits per second (Gbps). Always assuming, of course, that the two connected devices also support these speeds.
USB 3.2 is already in the starting blocks, for which the first devices will be released next year. Here is 20 Gbps possible. Any commercially available USB-C cable should be able to provide this data transfer rate. Only power supplies for high-powered devices, such as monitors or laptops, require special USB-C cables.
And what is Thunderbolt now?
It would not be technology if there were no exceptions: Apple offers an alternative to the USB 3.x, its own standard Thunderbolt, which also uses the USB-C port in its latest version. It offers even faster transfer rates, up to 40 Gbps, but requires special cables. However, MacBook Thunderbolt ports built into the USB-C format also support USB 3.1, so similar devices can be used with this standard.
It remains to note then that in the case of devices with USB-C, only first knows that USB-C cables can be connected to them. What can be transferred depends entirely on the devices used. Some support the load via their USB-C port, others do not. Some can provide a video signal via the USB-C port, others can not. It is therefore necessary to take a closer look at the technical data of a device to find out what you can actually do with a USB-C connection. At least we can plug the cables but also half asleep – that's the real progress.
