My friend monitors ATCS Monitor packets (railroad stuff) in his Toyota Corolla with a Motorola Maxtrac and ASUS laptop. Both feed into a splitter connected to the standard 12VDC receptacle. He's frustrated by the common problem found in foreign cars where the 12VDC power is lost when the ignition is turned off. Bottom line is he doesn't want to keep the car idling to keep his car battery charged and power the Maxtrac.
I suggested hardwiring the Maxtrac to the battery but he has cold feet...he's worried he will leave it on and drain the battery. I explained that American cars are already set up this way, but evidently I was unconvincing...
What would you suggest? I have one of those jumpstart batteries with a 12V receptacle on it. It is bulky and about 25 pounds and I don't remember if you can charge it from the car.
