    12V input to 19V@3A output converter

    Would like to build a 12V to 19V@3A converter. Basically it takes a car
    11-14V as input and provide a stable 19 +/-0.5V at 3A max to provide
    power for the laptop/notebook. Any such boost converter circuit available ?

    There are those universal notebook adapters, some of them have a car lighter plug too.

    A working TV? How boring!

      I know about those but I was more interested in building one myself. Found
      a boost controller from Linear Technologies (LTC3786) that supports an
      input voltage of 4.5-24V and output voltages up to 60V. There is a nice
      example of a 12-14V input to a 24V@3A design with some minor adjustment
      that should do what I need it to do.
