Charging the battery

You can charge your battery in several ways:

For the quickest charge, connect the device to a power outlet using the USB cable that came with the device and an Apple USB power adapter.Connect the device directly to a USB port on your computer (not an external keyboard) using the USB cable that came with the device. Your computer must be turned on and not in sleep or standby mode; otherwise, the battery may drain instead of charge.Depending on the computer, your device may charge quicker if you remove all USB devices except the keyboard and mouse.If using a portable computer, make sure it is plugged in to power and that the display (or lid) is open. If the display is closed, the computer may go into standby, sleep, or hibernation mode and the device may not charge.Connect the device to an externally-powered USB hub.For the quickest charge, you may need to disconnect other USB devices.

If you sync or use the device while charging the battery, your device might take longer to charge.

Charging with a FireWire-based power source is not supported, except on original iPhone and iPod touch (1st generation). If the device is connected to a FireWire-based charger or accessory, this alert screen will appear:
