The current version is Thunderbolt 3 and is mainly used with notebook, tablet PCs and corresponding peripherals. This connector allows you to connect, for example, compatible monitors, memory drives or various entertainment electronics. In addition, there are different docking stations that support multiple devices at the same time.
If you are looking for a used notebook or a computer that already has a Thunderbolt interface, simply use this feature to directly filter your search results. In the meantime, plug-in cards have already been introduced, which enable Thunderbolt to be retrofitted in the desktop PC.
In addition to audio and video signals, as well as pure data, Thunderbolt also transmits power. With version 3 up to 100 watts are possible, which is why some notebooks can be charged directly via this port. In addition, of course, a better supply of the additional peripherals is possible, so that, for example, smartphones can be loaded faster on such a port.
