So I make sure I bring laptop + iPad + external power charger now

If you are any kind of road warrior you carry a cube or adapter to double outlets since they are always in short supply in airport, hotel rooms, etc.
The best one I have is a triplet that is the size of a IPhone charger. It is UL listed...made in ULan Bator
