Hi, thanks for your question.
The SoundDock Series II system does require a power supply for operation. You could, however, use a third party Bluetooth audio receiver to stream audio from a wireless device to the AUX audio input on the system.
If you have any further questions on this setup, we encourage you to contact our technical support team who can assist. They can be reached at 1-800-380-4831 and are available 8:30am-10:00pm M-F, 9am-7:00pm Sat EST. We hope this helps, thank you!
