P650 200W Compatible Charger

Hello, My charging cable seems to have stopped charging my P650 laptop which is a few years old but in good condition. The website does not appear to sell replacements, though it has a listing, and I was wondering if anybody knows if I can buy a third party 200W laptop charging cable somewhere and have that charge the laptop or if it only functions with the Eluktronics model. Thank you for the help!
