Howdy all, swmbo is off to new york in a couple of days (hopefully bringing me back a r/c discovery rock crawler [-o< ) Anyhow, she and her girly shopping buddys are unsure of what to do about hair dryers/straighteners and other electrical things that are "essential" for there trip?? I know you can buy a travel adapter for plug types, but what about the voltage difference?? Many thanks for any help as i need to locate n purchase on today if required??
