“It's a PSU, not much to say except that it doesn't like certain multi sockets. I have a 1-to-4 gang wall socket that the PSU doesn't like, with warnings about not enough power for some USB devices (even when nothing attached except a keyboard dongle). When plugged into an extension plugged into that 1-to-4 gang socket, it is perfectly happy. Weird.”
“There are no problems to use the power supply in continental Europe also, but you need an adapter. Perhaps a brief note concerning this matter would be useful.”
