I use this cable to power my 15 inch MacBook Pro, iPad and Android phone and it works great no problem. The cord is a little longer than I originally expected (you don't know what 10ft is until you buy it), but I really appreciated the extra length. I can't verify the validity of the 100w charge claim, but it works fine at 60w with a MacBook. I actually went out and bought a second cable (and another charger) just to place a few around the house for convenience.
