USB-C PD 100W for laptop

Should I expect to be able to power a laptop with a USB-C PD 100W charger?

I've only just come across such a thing and am wonder whether they are worth buying.
 
They work great, at least the one just now powering this laptop. I can also use it to charge my phone in no time without fearing for the little wallknob to melt.
 
Check the laptop's manual as well. I own a laptop that has a USB-C port but does not support charging through it. I have to use a special adapter cable with a USB-C on one end and a male barrel connector on the other end.

how does PD work thru a 2 pin adapter ?
or you are stuck to 5V / 3A ?

or maybe the adapter does some magic to select a higher voltage profile

Do I need to specify PD 100W when looking for a charger? This is completely new technology to me and don't really know what to look out for when buying.

Any recommendations?

ThinkPad X1.

But how much of a difference does it make?

All the Thinkpads I've seen use 65 to 90W chargers, but at more like 19V than 5V, providing a round plug with a central pin.

Carefully check your X1's specs to see whaf charger is supplied or required. Check on ThinkWiki.
