Bose has released four SoundDock speaker systems for the iPod at the date of publication: the SoundDock, SoundDock II, SoundDock Portable and the SoundDock 10. Each of the speaker systems use a power cord for the power supply. In addition to the power cord, the SoundDock Portable uses a rechargeable battery as a power source. You can replace a power supply for the SoundDock if yours is lost or broken.
Check the bottom or back of your Bose SoundDock for a sticker with a serial number on it. The serial number is needed when ordering a replacement power supply.
Contact Bose Product Support at 877-210-3782 Monday through Friday, between 8:30 am and 10:00 pm EST; or Saturday, between 9 am and 7:00 pm EST. Tell the service representative that you are in need of a replacement power supply, and provide him with the serial number of your SoundDock. Replace power sources are not available online.
Pull the power supply cord out of the back of any of the Bose SoundDock systems and plug the small end of the replacement power cord into the "DC" connector.
