I needed to plug into UPS a device with standard Europlug 220V. However, my APC UPS has only eight C13 sockets.
What I did? I bought a standard multi socket extension cord/lead with 3 outlets (variant compatible with Type C and F Electrical Outlets). Then, I cut off the standard plug, and swapped it with rewirable DIY C14 plug.
BTW, there is at least one manufacturer that is producing UPSes with Europlug. It is Orvaldi. See the last photo.
