RE: Folks using notebook computers and working on tight energy budgets

save a few more mA if they get an inexpensive DC adapter for the laptop.

Mike, I've been trying to tell the list that for a couple of years now but
everyone keeps wanting to use an inverter.  One of the problems that can
also be encountered is that the laptop won't run off the inverter!  Not as
common today as it was a few years ago (laptops have improved).  A friend of
mine (who happens to be a EE) does extensive cruising in a motor-sailor.  He
has a very sophisticated energy monitoring system on board.  His equipment
showed about a 30% lower current draw using a 12v dc adapter than running
through a very good inverter system.  IIRC the only thing that he runs from
the inverter is a microwave. Virtually everything else is 12v dc or uses an
adapter that runs from 12v.  Enough said.....
