Re: using laptop in the UK
TigerDirect or NewEgg probably sell a converter to UK style plugs from US standards. Unfortunately, since the cable for the wall and the inverter box are a proprietary parts made by the manufacturer, you'd have to contact them about purchasing a cord that is intended for use in the UK.
I may have answered the wrong question as I did not fully understand what you were looking for. I apologize if I made a mistake.
