    The Tip

    The Tip: bring an extension cord

    DAVID LYON FOR THE BOSTON GLOBE

    If you’re going overseas to a country that uses different electrical sockets, bring one plug converter and a small extension cord with three or more outlets for US plugs. You can charge your computer, your camera battery, and your phone all at once without a fistful of expensive converters.
