P1 Gen 2, suggestions for USB-C chargers?

So, im looking for a USB-C charger for my Thinkpad, as my 170W is very chonky to carry around the university. I searched here but didnt find any "especific" recommendation for my model.

It would charge with an 65W? I know it has a GPU, but I would never game or anything while studying, etc. I will be more interested in a GaN charger, as well.
