Touring the Bottom of the iPad Exterior
On the bottom of your iPad are the speakers (two of the four speakers on iPad Pro models) and Lightning connector, as shown in the following figure:
- Speakers: The speakers plays audio — music or video soundtracks — if no headset is plugged in.
- Lightning connector: This connector has three purposes:
- Recharge your iPad‘s battery: Simply connect one end of the included cable to the iPad’s Lightning port and the other end to a USB port.
- Synchronize your iPad: Connect one end of the same cable to the Lightning connector and the other end to a USB port on your Mac or PC.
- Connect your iPad to cameras or televisions using adapters: Such connectors include the camera connection kit or other adapter cables. Make sure to use an adapter that works with the Lightning connector.
If you connect the USB cable to USB ports on your keyboard, USB hub, display, or other external device, or even the USB ports on an older Mac or PC, you may be able to sync, but more than likely you can’t charge the battery. For the most part, only your computer’s built-in USB ports (and only recent-vintage computers at that) have enough juice to recharge the battery. If you use an external USB port on a hub, you’ll probably see a Not Charging message next to the battery icon at the top of the screen (unless the hub has its own AC power source).
