I have a few laptops – a Dell Latitude D510, an Acer eMachine and an HP something
and I want to buy a generic laptop power supply for my car which has a 12 volt battery). I have looked on the laptop corded adaptors and don’t understand the amp verses wattage for each and how this relates to a 12 volt car battery?
What should I look for – does it matter – what about amp
Could someone please explain it to me?
Thanks
