This is the meat of the converter. Simply a coil of copper to reduce the electricity. I keep it in this ashtray to act as a insulator. It was so popular that Scott bought the same setup for his computer. There is also high speed ethernet driven internet access available in our rooms. This is wonderful. Also for those of you to come. All Sony and Canon products are safe to just plug into the wall if the prongs on the chords can fit. These companies have the traveler in mind and gone ahead and put these converters in their product power supply systems, thanks Sony.
