The downside, of course, is that as a travelled person, you would have a collection
of linecords from varios locales around the globe, and some appliances are just not suited to that sort of connector, however
you could use the two pin variety, commonly use on port, an plauing musical detachable linecords is easier than playing detachable plug.
My solution (especially for places like the UK with clumsy fused plugs), would be to use plug adaptors that would fix to the wall outlet or appliance plug.
