Can i use my iPod external battery pack, power adapter, wall outlet iPod charger, or other power accessory with iPhone?
Yes! iPhone also uses the same 30-pin dock connector as iPod, and the wide range of external battery packs, power adapters, wall chargers, vehicle chargers, aircraft chargers, USB and FIreWire charging cables, and many other Apple and third party power accessories for iPod are already compatible with iPhone! Many new vehicles as well as aftermarket automotive audio equipment are also available with optional iPod dock connectors. These same connectors with work with, and charge, iPhone as well, in addition to allowing music playback and control functionality just as with iPod. Since iPhone is a wireless device, it may cause interference with some iPod accessories; for this reason, look for the “Works with iPhone” label when you buy new iPod or iPhone accessories.
