Genuine 90W Samsung NP-P560i NP-P580 AC Adapter Charger

Does ANYone really utilize their laptop correctly unless they have, like, four cords? One for the home office desk, one for in front of the TV, one for your work office, and one that stays in your bag in case you might be, oh, some other place.
Works. Charges. Does not appear to show any difference in speed to the branded HP charger. Like it!
