I tried an inverter to keep my laptop up to charge...for a couple of
extended trips.  It worked, sort of...but often the inverter's auto shut
off would kick in.   A better more efficient way is to get the 12v plug
that is made for your computer, if you can.  They are more effective. less
loss of juice.   Inverters are not really great at taking 12v DC and making
it into AC, then converting that back to some other DC voltage.  You lose a
bunch in the conversions to heat, I guess.
  If you do get an inverter, get a pretty high capacity one...Nothing more
frustrating than to have the 'low battery voltage' alarm go off when you
are in the middle of something ...
