Modern laptops can demand up to 150 watts or more of 110V AC power with
everything turned on full power (which is usually how we run
navigation). Therefore the Auto Adapter concept is considered unsafe at
these power levels and most laptop manufacturers have dropped the 12
volt Auto Adapter option from their lineup.

Joe,
I hate to disagree with you but I own four modern laptops, two purchased
within the last year. None draws more than 45 watts, even when writing DVDs and
powering accessory equipment through the USB ports. The latest J. C. Whitney
catalog lists at least a dozen 150 watt DC to AC inverters which could supply the
required power. Most cost less than $40.
A laptop drawing 150 watts would be too hot to hold on your lap.
