I have just bought a USA produced dvd/tv for my son which has the 2 pin USA mains plug. The manual for the tv reads " Insert the AC plug (with the two blades) into a AC outlet having 110-220v, 50/60Hz. Does this mean that it can be plugged directly into a UK mains point using an adapter or do i need a 240v to 110v power converter. Any help would be grateful.
