I have my shack set up where I can operate every thing in it for at least 24 to 48 hours on battery power without recharging the batteries. Everything that is except my laptop. The internal battery last about 30 minutes enough time to shut it down. I would like to have it last a lot longer than that. I am considering either buying the converter to be able to use 12 volts or buying an inverter. According to the AC adapter the 110 side pulls 1.6 amps and the 19 volt output is 3 amps. I am thinking of a 400 watt inverter so I can use it for other things but if the 12 volt to 19 volt converter would pull considerable less power from the battery I would go that way. Thanks

The inverter is the least power efficient way.  Definitely use the 12volt adapter and spare your batteries.
