Good day! I am Independent Advisor Paul R. and also a Microsoft/Windows user like you and I am glad to be able to provide assistance to you today. I understand that you are looking to replace the power cord for your Surface Pro.
As long as the power cord is compatible with your device and also on your wall outlet/socket then there will be no issue on this one and it is also best to bring your device to the shop/retailer on where you will buy the power cord so that they can also check and test it on their end.
Regards,
Paul R.
