A few years ago I purchased a computer ac supply power cord while in Europe with the appropriate plug and it is far superior to using an NA plug and an adapter. I have since added a South African ac cord when doing work there. I am tired of fiddling with plug adapters and am now looking to expand my collection to an ac cord for the UK and original-equipment USB wall chargers for Europe and the UK. Is there North American supplier of such things? I checked Amazon in Canada and didn't quite find what I am looking for.
