Though I don't have an iPad, I have a bunch of electronic devices that charge via USB and need that extra oomph! I was pretty stoked when I saw this one has a 1A port and a 2.1A port. I have tried standard dual USB chargers that work well for low power devices, and I also had a 1A charger for the more power hungry ones. Unfortunately, that one couldn't handle my Axim, GPS receiver, and Zune at the same time. The Scosche handles that, and I'll bet more, but I'd need a USB hub to find out. It even charged my Axim while charging my Zune from a totally spent state.
It also fits snugly in the AC source in my car unlike the last one I had that kept losing the connection and I had to wiggle it around hoping it wouldn't get dislodged when I hit a bump. And also unlike the last one I had, the LED is bright even in sunlight so I can tell it's working properly.
