I'm trying to connect a relay between the DC connector and the powecord on my Ultimaker so I can turn it on and off via my Raspberry Pi and Octoprint. I've found a DC plug, both male and female, in a local store. The plug specification is 4A, the output on the AC adapter is 6.1A, if I remember correctly. So my question is if it's possible to use the DC plugs anyway or if I should look for a different solution?
