Hello 
How can I connect my new: Baseus Powerbank (65w 30k amp) for my Laptop (not supported type-c)
Welcome to the Technical Forum. Unfortunately lookin at the Baseus website they only list the options for the USB C. I am not sure on this one. Though this Forum is viewed by many . So hopefully someone will have an option or answer for this one.
Not sure I understand the question. Are you looking for something that will plug into USB C and convert to an input your computer has, such as the below cables, or do you mean something else?
