pimplepounder Can you use a 120ac to 12vdc converter to run a Garmin gps ? I don,t want to bring a battery in the house I want my wife to get used to the Garmin 7608xsv, I talked to Garmin they said it probly won,t work no clear answer. The unit electric specs say 10-32vdc- max power usage@ 10vdc 27w- current draw @12vdc 1.8A- max draw 12vdc 2.3A. The converter is a Garmin 120Ac-12Vdc 6amp
