I am visiting the USA in October, thinking of buying a Microsoft Surface Pro - they are about dollar for pound, and we are visiting two of the zero sales tax states!

Can any US Loungers help with this? What is the voltage range of the power adapters? Are they suitable for 100-240v? I know that I shall get a US plug, with two flat prongs, plus, perhaps an earth; this is not a problem.

I'd be grateful if any Surface Pro users could have a look at their power adapters and report the voltage range stamped on it.
