Yep, I was hoping someone here may have second hand one for sale. :)

you could order 65w phone charger with PD & Gan be more compact and portable...

The one above is a pretty good deal regardless of whether you buy new or 2nd hand.  Since it's relatively cheap anyway, I suggest you go with new.

Fair comment.
