Ripcord should be fine. There’s some discussion in another topic here. It’s mostly about power banks but the cables are critical to the function of using a powerbank with an elektron device so there’s information. I’ll find you a link.
Generally speaking, anything with the correct wattage, voltage and then correct size/polarity of tip is fine, but you’ll find that lower quality PSU’s don’t produce power as consistently for the surge at startup so you’re better off with a higher than factory amperage than a lower one. None the less, anything would be fine if it’s in spec. When using a ripcord it might not matter as much as when using a brick style PSU.
If you go into this topic and click on the magnifying glass at the top and search “ripcord” on the line that says “in this topic” you’ll get a bunch of hits. Good luck.
