my wife and i both have several dell inspire and laptop computers which we use during our motorhome travels they all use the same input voltage but they have two different size power connectors being able to supply power to our computers from coach's 12 volt dc sockets eliminates our need to use an external voltage inverter run our generator or be plugged into 120 vacuum power pwr has wisely now included both size connectors on its dell laptop car charger making it usable with all of our dell laptops this car charger is much more efficient than going through two power conversions that result from using an inverter and it works just fine we are using the pwr plus adapter for deep sky astronomy and remote primitive areas every amp is budgeted carefully i called pwr plus and the staff was quickly able to determine the actual load that their charger would put on my battery possibly the best
