Ultra Lead a travel plug, albeit a bulky one
Georges Moanack, a graduate from London's Royal College of Art, is the designer behind the Ultra Lead "electrical management system." It's basically a glorified travel adapter, but a lot better looking than the ones you buy at the airport (if you're like me, you've got about 15 of them sitting at home with nothing to do but file their nails and bitch about how their owner never takes them on holiday, because you forgot to pack them in your case) before jetting off somewhere.
There are British, European, USA and USB modules which you can buy separately, and they link together courtesy of the bright green adaptor. And if you're really bored, you can probably stick them together and revisit your childhood obsession with Sticklebricks.
