buying a refurbished MacBook Pro

Any Certified Refurbished MBPro from Apple will come with its own power supply.

There is no guarantee you could use the power supply from a 2012 MBPro with newer models. Late models have USB-C ports, not the old Magsafe power port, and they may also require a higher wattage power supply than your 2012.

No currently available refurbished Macs use the same power supply.

I suggest you only buy a refurbished Mac from Apple: Refurbished Mac Deals - Apple

I am curious as to why you say you want a Mac that uses the same power supply.
