Re: THE BRITISH ARE COMING!....and they need 220v power...
Im a Brit that works in the US regularly (LA and Tucson mainly) and as has been pointed out I've never need 220v due to the power supplies handling any voltage from 100 to 240.
The uk uses 240v by the way.
laptops normally come with one of three types of connectors , IEC ( kettle plugs) , figure of eight and clover leaf so I normally just carry a us plug to what ever my laptop needs.
The plugs used in Europe and the uk are both different so It might also be an idea to ask your client to ship over some uk and European multi socket extension cables then you can cut the plugs off and fit what ever the output from your step up transformer is.
Finally I would not use a us plug in a 220/240 circuit as they are not designed for that voltage .
hope this helps.
