Hi vfrmurphy,
If you are referring to the SoundDock Portable and are based within the US, we have accessories available on Bose.com linked below:
SoundDock Portable Accessories
If you are located outside of the US or are referring to a different SoundDock model, I would recommend contacting your local support center. If you go to our global page HERE, you can select your country, then scroll down to the bottom of the page and click "Contact Us". This should provide you with the phone number, email, and chat services for your country.
Thank you,
-Michael
