that is a dc supply, different animal, but you can get electronic converters that look similar and plug into your US walls and have a euro socket on the front for 220 or 240V appliances OR a transformer in a box with flying lead to plug.
A quick google and this is the first to come up: http://www.dcacpowerinverters.com/itemdesc.asp?CartId=EVEREST{493094CF-24FD-46A6-B4F3-D58C6689854A}&ic=VC100W
14 $ for the 100W should be ok for continuous use, or 20 $ for the 200W gives a bigger safety margin.
Ebay has some electronic converters very cheap occasionally but I have no knowledge of their reliability or production design competence, so a few extra $ for a brand name with warrantee is probably wise for your precious 7k.
