What you want is N4UAU's "My All-Purpose Voltage Booster".  It will 
boost 6V anywhere up to 65V and will supply
over 3A.  I purchased the kit about a year ago and use it to power my 
notebook computer.  I boost my auto or camper 12V battery voltage to the 
20V that the computer requires.  The author cautions about RF noise on 
the HF bands, but with careful
construction, should not be a problem.  I haven't heard a peep of RF 
from mine.  His project was written up in the July 1997 QST beginning on 
page 40.  I think I paid about $20 for the kit.

His info from the construction guide:
