Power Adapter

• You can plug the iPod dock connector into a power adapter if it is equipped with a USB port. Although the USB dock connector alone requires a powered computer, power adapters only need an electrical wall outlet to charge an iPod. Even if a powered computer is available, power adapters can still come in handy. Oftentimes, the USB dock connector can slow down computer performance when it initiates the iPod's music library to connect with iTunes. Because power adapters solely charge the device, they don't create the same kind of interference.
  
  

Car Chargers

• Long used to power mobile phones, car chargers have emerged as a popular choice for charging iPods. The iPod car charger is a12-volt dock connector that plugs into the in-car cigarette lighter socket. The charger uses the car's battery to supply the iPod with energy. Like any iPod accessory, iPod car chargers range from the basic to the elaborate. Most iPod car chargers are simple, relatively inexpensive cords. Upmarket versions typically have additional features like charging indicators and extra USB outlets. Some car chargers are also equipped with FM transmitters that enable drivers to listen to their iPod music on the car radio.
  
  Some AM-FM car stereos are now manufactured with internal iPod docks that do away entirely with the external setup of a 12-volt cord. In addition to controlling the device through an integrated iPod interface, these car stereos also charge mounted iPods.
  
  

Portable Speakers

• Numerous portable speakers are outfitted with a 30-pin dock connector for iPods. These units make it possible to stream audio from the iPod through the speakers. iPod speaker systems run the gamut in price, design and performance. Even the most basic models can charge connected iPods if the speakers are plugged in. These systems make it possible to play an iPod without compromising battery life. But if the speakers are running on their own battery, iPod energy will surely be depleted with use.
  
  

A Note About Compatibility

• Although many iPod charging solutions are available, none of them accommodate every model of the device. For instance, the iPod shuffle only has USB connectivity, and it is incompatible with the 30-pin dock connector. And while the iPod nano has dock connectivity, it does not fit the standard 30-pin dock connector. Before you select a charging solution, make sure it is right for your iPod. Some alternatives may include dock adapters to accommodate many different versions of the iPod.
