The iPad includes a 10 watt charger. I'm not sure what that means, but I assume it puts out more power than a standard USB port. It does say on Apples website that the iPad will charge on a computer's USB port. What I am wondering is: Will the iPad charge faster on it's own charger vs. a computer's USB port? Will other USB wall or car chargers work with the iPad? Can a USB Y splitter such as used by portable hard drives, where one plug is data/power and the other is power only work with the iPad to speed up charging? I don't know if there is enough information on Apples site for anyone to guess at this.
