When you search for "bluetooth speakers", most of the search results are speakers that contain batteries. I'm looking for one that gets its power from the wall, even though it gets the audio from Bluetooth.
(IMHO, batteries die eventually, and a plugged-in speaker can be more powerful)
(also, I prefer 2.0 speakers over 2.1 or single-unit speakers)
