In order to ensure a good charge to your iPod/iPhone, use this device rather than your USB Sync Cable. This compact power adapter offers fast, efficient charging at home, in the office, or on the go.

If you’re having problems with your battery not charging well, it can be caused by any of these reasons:

• Low-powered USB port
• The FireWire (IEEE 1394) ports on some Windows computers may not be powered
• Your computer goes to sleep
• There are too many devices in the FireWire chain
• iPod is locked up
• Faulty FireWire or USB cable
• Faulty port on the computer
• Faulty dock connector or FireWire port on iPod
