Review on Efficient Power Solution: HP Notebook 90-Watt Slim Adapter by Cory Miles

This adapter has about half the volume of the original adapter. I have an HP Elitebook 8470p, a fairly high end model, and this adapter charges and powers the laptop. The BONUS is the built in USB port which charges my iPhone while I work. Such a great idea. Both the cable that connects it to the wall and to the laptop are detachable. I ordered a three prong retractable cord to further lighten my load.
