Can I use a C13 power cord to replace the chinese C1 cord that came with my IBELink BM-K1+?
I’m not sure I understand. I don’t think C1 is the cord you currently have.
Search IEC 60320 on Wikipedia for the different connectors.
I don’t have a K1+ but I’d guess it has the standard C14 receptacle, which the C13 will plug into.
Your better off buying a new cord. You’ll need a c13 to (your receptacle). For a tripplite pdu the receptacle is a c14 or c20. If you’re plugging it directly into the wall it will a different receptacle. Feel free to reply with a picture of your power outlet and we can tell you what it is.
You can replace the end of a cable, but you’ll need to know how to splice a new end on.
