Need a charger for Pavilion DV6, anyone?

I just picked up the best freebie ever...

I have already upped the RAM to 8GB, put a larger HDD inside, and have put a macOS compatible WiFi card inside (BCM943224HMS).

I have 14 spare laptop chargers, but none with the outer ring and inner PIN that this requires. If you can help me out, please PM me.

I don't have a lot of money, and I am in Tasmania - Australia.

Many thanks in advance :-)
