Whenever my parents visit there’s always a dilemma about what gadgets they can take back with them. On the one hand they can walk into Best Buy and pick up any 110V gadget and buy the appropriate voltage converters but on the other hand you can take a trip out to Edison, NJ or Jersey City, NJ or Jackson Heights, NY.

808 Newark Ave,
Jersey City, New Jersey
