I am aware that such "minimally invasive" options might well not be available everywhere. On the other hand, my experience is that it's not difficult in Europe to buy "power strips" or whatever you want to call them, boxes of receptacles on the end of an extension cord, which also include a USB power supply. That also seems to me like a reasonable compromise.
