What the heck is a thunderbolt port for?

274 viewsOtherTechnology

I have a thunderbolt port on my laptop. I’ve tried to look up what it is used for, watched some videos, but I’m still confused. Can I use it to power my laptop? Does it transfer stuff faster? Do I need a special cord? Can I plug that cord into something normal? Explain it to me like I’m five please.

Think of it this way: A thunderbolt port is essentially a PCIe slot on a cable. It has native access to the PCIe bus in ways that even high-speed USB doesn’t have.

Any regular PCIe device in an external enclosure can be connected via Thunderbolt and function identically as though it were inserted directly into a slot on your motherboard.

Additionally, per the Thunderbolt spec, every Thunderbolt port is also a USB port and a Display Port as well, so yes, you can charge your laptop through it.
