Can I use any Mac or AC adapter to charge the iPad?
Not quite. When we tried to plug the iPad into existing iPod or iPhone accessories, we discovered that some Macs and AC adapters we tried were able to charge the iPad; others caused the iPad to declare it was “Not Charging” despite it being connected and syncable. It turns out that the iPad has some very specific charging requirements. With the included 10-watt USB power adapter, it charges awake or asleep. On high-powered USB ports such as most recent Macs and the iPhone power adapter, it charges as well, though more slowly, according to Apple. On Macs and PCs without high-powered USB ports, the iPad will charge when it’s sleeping, but when it’s awake it will display that “Not Charging” message in the status bar at the top of the screen. Will my iPhone accessories work with it—specifically the wall charger and headphones? I remember when the iPhone came out I had to buy an adapter for my iPod headphones to make them work on the iPhone. Nothing hinky this time—your headphones will work
