Dell Chromebook 11 3180 3189 uses a very special power jack connector, the power jack is soldering to a iron cover, people have to replace the whole part when the jack is broken/burnt, this is the correct part: https://www.dcincable.com/xnj46-0xnj46-c..., remember not to move the laptop while charging the battery, a good habit can make the laptop working longer.
