Need a small portable speaker with no batteries or adapter required, for mp3 + laptop?

Question

Any recommendations on any brands of this kind of speaker? Like the creative popz speaker for example, powered from audio devices.

Please & Thank you! ;D

Answer 1

If you find such a thing I don't think you are going to be happy with it because the audio output level of the laptop or mp3 is so low it needs amplification.  I don't know of any device that can deliver the amount of power that you need in order to satisfactorily amplify the output signal without batteries or a power adapter.

Good luck and 73 from the Fisherman
