Type C is the connector which can either be power only, power and data, power data and video, or thunderbolt which is basically faster power data and video. You can’t really burn out the port with the wrong device or charger, it either won’t charge, charge slowly, or not work.
Thanks for answering. Is a old computer with thunderbolt 2 port able to connect thunderbolt 3 & 4 monitors or storage devices? I’m tempted to get an old thunderbolt 2 card for my computer, but don’t know if it’s really a useable port in 2023
Thunderbolt 2 can support a single 4K monitor and they still make TB2 external storage devices. Apple makes a bidirectional adapter that will allow some 3&4 devices to work with a 2 port but every device is different and most will not be officially supported. Link to adapter is https://www.apple.com/shop/product/MMEL2AM/A/thunderbolt-3-usb-c-to-thunderbolt-2-adapter
I would not add a TB2 card to an older machine though. Just find an adapter that works with the fastest port on that machine. There are plenty of devices that work well with usb3.
