Agree with comments below, am observing that the British (commonwealth etc) plug standard is a good common denominator (and a perfect calthrop. grin!). Living in North America where the 110 V is standard... the GBR plug/socket is a lovely standard, my brother-in-law gifted us a UK power bar for travel a few years ago, worked great. [[1]]. Since then, it's become common that wallwarts handle 100-240, so recently I just use physical adapters, and if need be wallwarts with multiple charging ports and/or feed-through mains sockets. [[1]] use whatever physical adapter to power it -- we know that it's ok for 240 V. Then use whatever adapters to charge. I did have a bagful of physical adapters.
